Schade, Jutta. "A design process perspective on the energy performance of buildings." Doctoral thesis, Luleå tekniska universitet, Byggkonstruktion och -produktion, 2013. http://urn.kb.se/resolve?urn=urn:nbn:se:ltu:diva-25984.
Full textAbstract:
From a sustainable development perspective, buildings should be designed to be as energy-efficient as possible, as the contribution of buildings to total energy consumption has steadily increased, reaching between 20% and 40% in the developed countries. One of the main challenges for achieving this goal is to develop more cost-effective systems and processes for energy renovation and modernising of the building stock of Europe. This challenge is addressed in this thesis. The research presented herein has had the overall purpose to identify and explore obstacles in the design process of constructing more energy-efficient buildings. Three research questions have guided the research work: (1) How can life cycle cost be used to predict the cost benefits of energy efficient buildings?; (2) How can the handling of energy performance requirements in the design process for buildings be improved?; (3) How do client requirements, political governance and regulations affect the design of energy performance in buildings? The research is based on literature reviews, interviews and surveys, as well as case and computational studies. A computational study was performed with three different building types situated in Finland using three different energysaving design concepts for each building. Energy consumption and construction costs were analysed for each case and the financial viability was analysed using the discounted payback method. Individual interviews were carried out to determine to what extent life cycle cost calculations are used in the construction sector and how energy performance is taken into account in model-based design processes for buildings. A decision-making framework and an axiomatic design model for a performance-based design process was then developed and the conceptual model was compared with a real case of low energy design in Sweden. Finally, a survey explored energy conservation strategies in the design of buildings in Germany and Sweden and a longitudinal investigation of key policy instrument regarding energy conservation in Germany and Sweden was conducted to support the main findings of the survey. The main results of the research work show that: * There is no evidence that the design of energy performance is considered differently in the design process for buildings in Sweden and Germany, even if regulations and building codes differ between the two countries. However, the somewhat steeper reduction in space heating in Germany compared with Sweden could be due to the stricter regulation in the building codes in Germany over the last decade. * The transparency of the design and the associated decision-making about energy performance can be improved by using the requirement management model developed, which is based on axiomatic principles and the proposed decision-making framework for evaluating, structuring and detailing the requirements from the conceptual to the detailed design stages. * Energy performance design can give cost benefits over a specific time for a building, as measured by the resulting life cycle costs. In general, life cycle cost analysis can be a tool for evaluating cost benefits over time and provide support for the decision-makers, but the challenges and uncertainties of its use have to be taken into account in the decision-making process. To conclude, the "energy gap" between regulations and what is technologically possible can be reduced to a certain extent by facilitating the energy design process with a performance-based design process and decision-making tools that support the evaluation of life cycle performance. However, it seems that regulation is a more important driver for the development of technology for low energy housing than market forces so the regulatory limit should therefore be set with respect to what is possible and not with respect to current practice.Godkänd; 2013; 20121121 (jutsch); Disputation Ämne: Byggproduktion/Construction Engineering Opponent: Professor Johnny Kronvall, Strusoft AB/Malmö högskola, Malmö Ordförande: Professor Ove Lagerqvist, Institutionen för samhällsbyggnad och naturresurser, Luleå tekniska universitet Tid: Torsdag den 7 februari 2013, kl 10.30 Plats: F1031, Luleå tekniska universitet

Full textAbstract:
Currently there is a growing pressure on energy efficiency for new buildings in the UK and worldwide. This has arisen partly due to the increasing awareness of the public for sustainable building construction. In addition, there is pressure on building materials manufacturers, due to new government regulations and legislations that are targeting energy usage and carbon dioxide emissions in new buildings. This research work reports on unfired clay building materials (unfired clay bricks) technology for sustainable building construction. The technology aims at the reduction of the high energy input, especially that arising from firing clay bricks in kilns. The research has investigated the use of lime or Portland cement as an activator to an industrial by-product (Ground Granulated Blastfurnace Slag-GGBS) to stabilise Lower Oxford Clay (LOC). Portland cement was used in the formulation of the unfired clay brick tests specimens predominantly as a control. The development of an unfired clay brick in this current work is considered by the researcher as a significant scientific breakthrough for the building industry. Another breakthrough is the fact that only about 1.5% lime was used for GGBS activation. This is a very low level of usage of lime that is not comparable to, or sufficient for, most road construction applications, where far less strength values are needed and where 3-8% lime is required for effective soil stabilisation. Hence, the final pricing of the unfired clay brick is expected to be relatively low. Industrial scale brick specimens were produced during two separate industrial trials. The first trial was at Hanson Brick Company Ltd, Bedfordshire, UK, while the second was carried out at PD Edenhall Ltd, Bridgend, South Wales, UK. The results clearly demonstrate that all key parameters such as compressive strength, thermal properties and durability were within the acceptable engineering standards for clay masonry units. From the environmental and sustainability analysis results, the unfired clay material has shown energy-efficiency and suggests a formidable economical alternative to the firing of clay building components. This study is one of the earliest attempts to compare fired and unfired clay technology, and also to combine energy use and CO2 emission for unfired clay bricks relative to those bricks used in mainstream construction. This is an attempt to come up with one parameter rating. The overall results suggest that the spinoff from this technology is an invaluable resource for civil engineers and other built environment professionals who need quick access to up-to-date and accurate information about the qualities of various building and construction materials.

Full textAbstract:
It is vital that Turkey keep abreast of developments in the world and build up its technology to become a developed country. Steel construction is one of these areas. In this context, the main purpose of this study was to define, analyze and evaluate the general characteristics of structural steel and steel construction with the purpose of throwing new light on its advantages and disadvantages.
Within this framework, a literature survey was conducted on structural steel components and structuresand on steel construction in Turkey. Additionally, a case study was carried out on a steel office building in Ankara. In this, the Tü
rkiye Esnaf ve Sanatkar Kredi Kefalet Kooperatifleri Merkez Birligi (TESKOMB) Building was investigated in terms of the design and production criteria for steel structures and to determine problems faced during these processes. As a result of this study, the existing condition of the construction sector and the means to improve use of structural steel in Turkey were discussed more realistically.

Full textAbstract:
In the construction sector, capturing the building product in a single information model with good interoperable capabilities has been the subject of much research efforts in at least the last three decades. Contemporary advancements in Information Technology and the efforts from various research initiatives in the AEC industry are showing evidence of progress with the advent of building information modelling (BIM). BIM presents the opportunity of electronically modelling and managing the vast amount of information embedded in a building project, from its conception to end-of-life. Researchers have been looking at extensions to expand its scope. Sustainability is one such modelling extension that is in need of development. This is becoming pertinent for the structural engineer as recent design criteria have put great emphasis on the sustainability credentials in addition to the traditional criteria of structural integrity, constructability and cost. Considering the complexity of nowadays designs, there is a need to provide decision support tools to aid the assessment of sustainability credentials. Such tools would be most beneficial at the conceptual design stage so that sustainability is built into the design solution starting from its inception. This research work therefore investigates how contemporary process and data modelling techniques can be used to map and model sustainability related information to inform the structural engineer’s building design decisions at an early stage. The research reviews current design decisions support systems on sustainability and highlights existing deficiencies. It examines the role of contemporary information modelling techniques in the building design process and employs this to tackle identified gaps. The sustainability of buildings is related to life cycle and is measured using indicator-terms such as life cycle costing, ecological footprint and carbon footprint. This work takes advantage of current modelling techniques to explore how these three indicators can be combined to provide sustainability assessment of alternative design solutions. It identifies the requirements for sustainability appraisal and information modelling to develop a requisite decision-support framework vis-à-vis issues on risk, sensitivity and what-if scenarios for implementation. The implementation employed object-oriented programming and feature modelling techniques to develop a sustainability decision-support prototype. The prototype system was tested in a typical design activity and evaluated to have achieved desired implementation requirements. The research concludes that the utilized current process and data modelling techniques can be employed to model sustainability related information to inform decisions at the early stages of structural design. As demonstrated in this work, design decision support systems can be optimized to include sustainability credentials through the use of object-based process and data modelling techniques. This thesis presents a sustainability appraisal framework, associated implementation algorithms and related object mappings and representations systems that could be used to achieve such decision support optimization.

Full textAbstract:
The green building market has seen tremendous growth in the past decade. Organizations such as the US Green Building Council have emerged to become a dominant leader in the building industry. Although the green building rating systems are cross-disciplinary, much of the focus has been directed towards design-related input.
General Contractors play an important role in delivering successful sustainable construction projects. If an integrated project delivery method is chosen, the General Contractor may offer insightful preconstruction assistance by providing ideas on green construction methods and materials. As sustainable building practices become more prominent in the construction industry, General Contractors must remain knowledgeable on current green building standards in order to stay competitive.
Two of the most important aspects of business for a General Contractor involve time and money. Through qualitative literature review and quantitative results from a case study, this research analyzes time and cost in sustainable construction projects from a General Contractor's perspective. The research also examines whether the management of a sustainable construction project is substantially different than a non-sustainable construction project for a General Contractor. Finally, because the green building process involves multiple parties, the collaboration effort from all parties involved in a green building project will be studied.

Full textAbstract:
Space conditioning and lighting together account for about a third of end-use energy consumption in residential buildings in Hong Kong. Previous research shows that such energy consumption can be significantly reduced by employing energy-efficient building envelope design. However, despite that fact, the envelopes of many residential buildings in Hong Kong are designed in ways that impair building energy performance. For example, most residential buildings in Hong Kong have single-glazed windows and solar-absorbing roofs, many leak airs, and some have no external wall insulation or exterior shading.
There are many energy-efficient envelope (EEE) design measures that improve overall building energy efficiency, but their selection has been widely recognized as a difficult task for design decision-makers, as it requires good engineering judgment and substantial building performance data. Apart from the energy considerations in EEE design, the reasons why professionals do or do not incorporate EEE design measures voluntarily into building design have not been thoroughly investigated. The majority of previous studies have focused on evaluating design alternatives after the design decision is made, but largely overlook the issue of informing the design before the decision-making process.
The aim of this research is to inform design decision-making for selecting appropriate EEE measures for residential buildings in Hong Kong. The research included three major interrelated steps. Firstly, a comprehensive literature review was conducted of the energy-related parameters and non-energy-related factors critical to the selection of EEE design measures in the Hong Kong context. Secondly, the influential design parameters identified from the literature review were used for detailed parametric simulation and analysis. Their effects on building energy performance were evaluated, and their relationships with selected outputs were analysed. Thirdly, a survey was set up to investigate the perceptions of building professionals about EEE design decision-making criteria and factors affecting the adoption of EEE designs. Taken together, these three study components contribute to the development of a decision support framework that buttresses the effective selection of appropriate EEE design measures for low-energy residential buildings in Hong Kong. The framework shortlists the critical parameters in EEE design, highlights their effects on building energy performance, points out the drivers and barriers to adoption, and suggests strategies to expedite the adoption of those measures.
The findings should support the effective comparison and selection of EEE design measures for delivering low-energy residential buildings in Hong Kong. They should also help to achieve the targets of relevant industry and government programmes in Hong Kong for expediting the adoption of EEE design measures.published_or_final_version

Clarke, John Lester. "Sustainable buildings : sustainable behaviour? : to what extent do sustainable buildings encourage sustainable behaviour through their design, construction, operation and use?" Thesis, Kingston University, 2013. http://eprints.kingston.ac.uk/27728/.
Full textAbstract:
The environmental impact of human behaviour on the design, construction and operation of buildings is often overlooked, frequently resulting in sub optimal performance over the lifecycle of the building (credibility gap and value-action gap). An over-reliance on technological and market solutions (false positivity) throughout the design, construction and operation of sustainable buildings means changing user behaviour is not currently envisaged by all but the most sustainability-minded built environment professionals. This study aims to develop an understanding of the dynamic and complex systems by which responsible environmental, social and economic action (sustainable behaviour) emerges from the relationship between people and the built environment. The primary research question asks to what extent sustainable buildings encourage sustainable behaviour, with broader research objectives covering the need for sustainable buildings and their social, environmental and economic benefits; a clear definition of sustainable behaviour and sustainable buildings; identifying opportunities for behavioural change from current best practice and how behavioural change theory can be applied to the built environment to encourage and optimise sustainable behaviour. Literature review reveals existing theory and practice in the fields of sustainability, architecture, behavioural psychology and pedagogy applied generally to the design, construction and operation of sustainable buildings. Five exemplar sustainable buildings with pedagogical functions are also investigated. The primary empirical research methodology uses grounded theory, ethnography and phenomenology through interview and survey data analysis, highlighting common best practices and innovative approaches, as well as revealing barriers to achieving sustainable built environments that encourage sustainable behaviour. The research reveals that there are numerous opportunities for behavioural interventions at critical stages throughout the lifecycle of buildings where ‘value-action’ gaps between our intentions to be more sustainable and our often sub-optimal actions or behaviours are identified. Strategies includes education, information provision, training, experiential learning, feedback, participation and regulation. The research contributes original knowledge by relating the way building mechanisms for change can be understood through the lens of behavioural psychology and the synthesis of the three disciplines of sustainability, architecture and pedagogy.

Full textAbstract:
This creative project examines trends in school planning and design at both the community and site levels. At the community level, two trends have shaped many of the decisions made in school planning: consolidating schools into mega-sized schools and placing schools on the periphery of development. These practices contribute to sprawl, urban disinvestment, racial and social segregation, environmental degradation and educational inequality. Alternatives in school planning such as school renovation and schools as community centers, are examined through case studies.At the site level, schools are typically built on acres of land covered by lawn, sports fields and asphalt parking. Research shows that school grounds can serve as valuable educational resources when designed as learning landscapes. A conceptual master plan for Storer Elementary School in Muncie, Indiana illustrates how a bland school landscape can be transformed into an educational resource to improve learning, environmental quality, safety and health.Department of Landscape Architecture

Full textAbstract:
In the last few decades, there has been well documented evidence that the performance of the public building projects in local authorities in Indonesia does not fully meet the expectation of the stakeholders involved and demonstrates sustainable practices. This mediocre performance impacts on the competitiveness of building industry, and therefore would require the development of a strategic approach to address these fundamental structural and cultural issues. The strategic approach, which facilitates sustainable practices, to a large extent, depends on the local priorities, goals and success criteria, which are dynamic and influenced by the expectations of various stakeholders involved in the procurement of public buildings. This research aims to develop a conceptual framework that will help local authorities to enhance sustainable practices of public building management. The empirical research work adopted case study strategy involving interviews with 24 public building practitioners and investigation of building defects on 34 projects. This research proposes LACU model, which represents a triangular relationship between contractors, local authorities and building end-users to illustrate the interactions between parties when undertaking their tasks throughout the project lifecycle. A framework of Sustainable-Dynamic Capabilities was developed and applied to enhance understanding of sustainability provisions in public building development. Based on this framework and stakeholders’ mapping illustrated by LACU model, this research has enhanced understanding on strategies of local authority to implement sustainable practices on public building projects. A template analysis through interview transcripts has been adopted to identify strategic approaches of local authority to deliver successful project by determining the roles of stakeholder at three different levels, provincial, regency or city and special authority. This research provides a novel empirically-based guidance for the local authorities to undertake sustainable public building procurement throughout project life cycle by adopting strategic approaches, such as employing innovative construction method, appropriate policy intervention by local leader, and changing business orientation.

Doctoral thesis, Faculty of Engineering and the Built Environment, 2005. http://hdl.handle.net/11427/30115.
Full textAbstract:
The fundamental premise of research presented in this thesis is the search for conceptual approaches and practical measures to enhance the practice of building assessment in fostering sustainable construction. Hence, this thesis advances the theory for the practice of building assessment that incorporates the principles of sustainable development. The research findings are communicated via a functional specification for a building sustainability assessment model, suitable to the South African context. The research focuses primarily on process-related aspects of building assessment. Important insights for the development of the model's specification are gained from the review of the practice and experience of Environmental Assessment (EA) in addressing sustainability at a project level. Lessons are also drawn from the Process Protocol (PP), which provides a means of describing the building project process in a way that is transparent and accessible to building stakeholders. The most relevant insights sourced from these two fields of expertise are grouped into three key themes. These include integration (i.e. integration of sustainability principles, stakeholder values and perspectives), transparency and accessibility (i.e. open participation and communication competence) and collaborative learning (i.e. active involvement and transfer of knowledge). It is proposed that these themes form key outcomes of building assessment and be viewed as crucial functionalities of the model.
The model is presented as a generic method that can be customised to suit the context of its application. The potential use scenarios of the model, identified in this thesis, include the formulation of a building project proposal, a building project sustainability appraisal and a building performance audit. The use of process maps produced through this research facilitates the identification of interfaces between the model and the building process in terms of decision-points and associated information needs in each use scenario. The model's user personas are also discussed (i.e. building stakeholders) with regard to the potential benefits and challenges of their participation in the building assessment process. The theory for building assessment advanced in this thesis was validated during a workshop with South African academics and built environment practitioners, held at the University of Cape Town.
The thesis concludes that building assessment methods can do more than assess the sustainability of a building. More importantly, they provide a means of introducing the principles of sustainable development into the processes that produce the built end-product. This suggests a need to move beyond the terminology of building assessment and instead talk of enhancement models that would facilitate a shift in the practice of building assessment from measuring to one of proactive improvement.

Full textAbstract:
Construction is known for consuming large quantities of raw materials and high amounts of energy. In 2018, the construction industry was responsible for 6% of global energy consumption, 11% of global CO2 emissions, and approximately 36% of the total waste in the European Union. These drawbacks are just a part of the gap between the construction sector and Sustainability, which can also be perceived as challenges to the industry and demands for new and innovative strategies to increase Sustainability. For example, recent efforts of EcoDesign on structural systems show a trend in the importance of materials efficiency, durability, adaptability, and reuse. This thesis aims to create a set of guidelines that will help designers and other construction stakeholders apply Design for Deconstruction and Adaptability DfD/A principles to increase the knowledge of how structural design and structural systems in buildings can be designed to promote Sustainability. For this purpose, a grading tool to assess structural systems based on the ISO 20887 was developed. The general methodology for this research was adapted from Design Research Methodology with a particular focus on the Product Development approach for the tool development. A literature Review was conducted in both scientific and grey literature to identify relevant information and current efforts on sustainable design of structural systems and application of DfD/A principles on the construction sector. Three additional methods for data collection were used: (1) questionnaire for identification of customer needs and expectations, (2) benchmarking to identify similar tools, strategies, and certifications systems that include sustainability performance in buildings; and (3) workshops with the purpose to rate the usefulness quality of the tool based on the application of the tool by potential users in different case studies. A ready-to-use computer-based EcoDesign tool was developed. The assessment performed by this tool consists of an indicator system of DfD/A strategies to enhance sustainable development by improving material efficiency and stimulate a circular economy in the construction sector. A top-down approach was used for the concept generation, which starts with the ReBuilding Index as an indicator of sustainable performance for structural systems. This index is based on five categories defined on the relationship of the DfD/A principles with the design process of the structural system. A total of 20 principles are distributed in these categories, defined by 54 strategies to reach the goal of the principles. The tool was tested by 11 potential users with different roles in the construction sector. Five case studies were selected to grade the design of five different typologies of structural systems. The usefulness quality of the tool was evaluated based on indicators of usability, utility, and user experience. It was found that developing the tool based on DfD/A principles and the ISO 20887 gave the tool a solid theoretical background and a flexible structure that can be used for sustainable design or as part of an extensive framework of certification systems or ecolabel programs. The tool accomplishes the goal of grading and helping to improve the structural design. However, during the evaluation of the tool, many barriers and difficulties of application were found. Therefore, these findings and obstacles are instead identified as challenges and turn them into opportunities for improvements in future versions of the tool.InFutUReWood project

Full textAbstract:
A substantial amount of credible evidence shows that properly designed healthcare built environments can positively impact upon the health outcomes of the building users. This offers an opportunity to improve the quality of healthcare through appropriately designed healthcare built environments. Evidence-based design (EBD) emerged within healthcare building design practice to enhance the process of designing with credible evidence. This research explored improvement opportunities for EBD in the UK which would subsequently improve the quality of healthcare through built environment interventions. Specifically, three key research gaps were addressed during this research. Firstly, this research explored current practices of evidence use during healthcare designing and opportunities to increase the direct use of research-based evidence and alternative ways of conveying research-based evidence into the design process through other source of generic evidence for design. Secondly, this research explored how evidence could be effectively expressed within healthcare design standards, guidance and tools (SGaTs) in the forms of performance and prescriptive specifications. Finally, considering the unique nature of built environment design, this research explored how project unique contextual circumstances impact EBD processes and how practitioners reflect on these circumstances. These challenges were then transformed into six objectives. Following a comprehensive literature review, this research was divided into four phases. First, a model of the sources and flows of evidence (SaFE) was developed to represent evidence for EBD within generic evidence for design. The initial conceptual model was developed through desk study, based on the literature review, self-experience and the experience. This model was then verified with the comments from five un-structured interviews conducted with lecturers and senior lecturers of the School of Civil and Building Engineering. Finally, the model was validated using 12 semi-structured interviews conducted with design practitioners from the industry. In addition to the validating the sources and flows of evidence these interviews revealed rationales behind design practitioners use of evidence from four types of evidence sources. These results revealed improvement opportunities to increase the intake of research-based evidence use during healthcare built environments designing. The main data collection method for this research was case studies. Eight exemplar design elements within three case studies were investigated to explore details of evidence use practices; practices of using performance and prescriptive specifications; and impact of project unique contextual circumstances for EBD process and how design practitioners reflect on these circumstances. Results of this research revealed that EBD needs to be supported by both externally published research evidence and through internally generated evidence. It was also identified that EBD could be significantly facilitated through research- evidence informed other generic design evidence sources. Healthcare design SGaTs provides a promising prospect to facilitate EBD. Performance specification driven healthcare design SGaTs supplemented by prescriptive specifications to define design outputs and design inputs could improve effective use of evidence-informed SGaTs. These results were incorporated into a framework to guide development of healthcare design SGaTs. Finally, by exploring how projects unique contextual circumstances impact EBD processes and how practitioners reflect on these circumstances, this research identified the need for procedural guidance for designers to guide evidence acquisition, evidence application and new evidence generation.

Full textAbstract:
Building industry is one of the most influential economic sectors, which accounts for 10% of the gross domestic product (GDP) globally and 40% of the world energy consumption. To achieve the goal of sustainable development, it is necessary to understand the sustainability performance of building construction in the environmental, the economic and the social aspects. This study quantitatively evaluates impacts of building construction in the three aspects by using the recently developed life cycle sustainability assessment (LCSA) methodology, in which environmental life cycle assessment (ELCA), environmental life cycle costing (ELCC), and social life cycle assessment (S-LCA) are integrated. The scope of this research covers ‘cradle-to-site’ life cycle stages, from raw material extraction to on-site construction.
Three life-cycle models are developed, namely the Environmental Model of Construction (EMoC), the Cost Model of Construction (CMoC), and the Social-impact Model of Construction (SMoC). EMoC is a comprehensive ELCA model that evaluates environmental impacts of building construction by considering eighteen impact categories. CMoC is an ELCC model that provides analyses on construction costs and externalities. SMoC is an innovative S-LCA model being able to quantify social impacts of building construction in thirteen social impact categories. The three models are then integrated into a newly proposed LCSA framework.
In order to select an appropriate LCIA method for EMoC, the differences among existing life cycle impact assessment (LCIA) methods are investigated. It is found that LCIA methods are consistent in global impact categories, while inconsistent in regional impact categories. ‘ReCiPe’ is selected as the LCIA method to be used in EMoC. Midpoint and endpoint approaches of ‘ReCiPe’ can lead to different interpretations. Endpoint approach emphasizes on certain impact categories and can only be used when midpoint results are provided.
A life cycle inventory is established for ready mixed concrete and precast concrete based on site-specific data from concrete batching plant and precast yard. EMoC is employed to compare environmental performance of precast and cast-in-situ construction methods. It is found that adoption of precast concrete can significantly improve environmental performance of building construction. SMoC suggests that adoption of precast concrete can have both negative and positive impacts on local employment.
A case study is conducted to test the model performance. It demonstrates that environmental impacts of ‘cradle-to-site’ construction activities are mostly attributed to the material stage. The external cost due to carbon emission is about 2% of the total construction cost. Environmental-friendly on-site construction practices can significantly improve social performance of building construction.
The major findings of this study are verified through interviews with the local experts in Hong Kong. These validation interviews confirm that the proposed LCSA framework and the developed models contribute to the building industry in Hong Kong. In particular, this study can be used as a supplementary to the building assessment scheme, HK BEAM Plus. Results from this study can improve the understanding of building sustainability.published_or_final_version

Full textAbstract:
The construction industry is by far the greatest consumer of resources and waste producer of all industries in the UK; being responsible for 32% of total waste generation, which equates to three times the combined waste produced by all households. Consequently, construction waste management and minimisation became a priority in the EU and UK environmental policy programmes resulting in a combined plethora of government-driven waste related legislation and guidance documents to curb construction waste production. Similarly, an ever-increasing global research on construction waste has been conducted over the last decade ranging from ‘soft' onsite waste auditing tools and methodologies to ‘hard' material and recycling technologies. However, the current state-of-research is largely dominated by endeavours to manage waste that has already been produced. Very few studies have been undertaken on how architects could go about minimising waste through a change in design practices. Hence, this research set out to construct and validate a Designing out Waste (DoW) Framework to assist architects in embedding design waste reduction strategies in each design stage.

Full textAbstract:
As a major energy consumer and CO2 emitter, buildings have an undeniably important role to play in cutting carbon emissions and combating climate change. Over the recent decades, green buildings have gained increasing attention and popularity from various stakeholders in the construction industry. Green building design practice builds upon the conventional building design practice but adds the concerns of environmental impacts and occupants’ well-being in the design philosophy.
Many researchers advocate utilizing optimization for green building design due to its capability in obtaining improved design solutions and providing building designers a better understanding of the design space. A comprehensive and in-depth review on previous relevant optimization models has revealed the following two limitations which might undermine their application in practice. Firstly, the focus of optimization in most of these models was on the reduction of cost and energy consumption while occupants’ comfort level in terms of indoor environmental quality was seldom considered. Secondly, for those models which have set comfort level of indoor environmental quality as a design objective, only thermal comfort was taken into account and thus they failed to address other essential factors governing indoor environmental quality such as visual comfort and indoor air quality.
Aiming at addressing the limitations of previous related studies, this research has developed an improved optimization model for green building design with a more comprehensive set of design objectives, namely minimization of cost, minimization of energy consumption, and maximization of occupants’ comfort level in terms of indoor environmental quality. The importance of the three design objectives and the necessity for including them in the model were verified through a series of semi-structured interviews with respondents from different stakeholder groups in relation to green building design and construction. The three design objectives are evaluated in the developed model in terms of (i) cost according to life cycle cost; (ii) energy consumption analyzed by a widely-adopted building energy performance simulation program – EnergyPlus; and (iii) comfort level of indoor environmental quality by adopting an empirical-based multivariate-logistic regression model identified from literatures. Non-dominated Sorting Genetic Algorithm II, a powerful multi-objective optimization technique, was selected as the optimization engine in the developed model. The developed model was then implemented into to a prototype tool in the MATLAB environment which can be utilized by building designers to determine the appropriate design solutions. Through a hypothetical office building design problem, the applicability of the model was demonstrated. Finally, the developed model was validated through demonstration and face-to-face discussion with experts.published_or_final_version

Full textAbstract:
In the year 1755, the lower part of the city of Lisbon was hit by a severe earthquake. Immediately following the earthquake a complex reconstruction process began, which introduced new urban, architectural and constructional concepts. This resulted in the creation of new innovative rentable buildings termed the Pombaline rentable buildings, after the Marquis of Pombal who directed their construction. This thesis comprises a wide ranging and detailed study of these buildings. At the beginning of this work, in Chapter I, "The Pombaline rentable building" is placed in its historical context. The origins of the old city are described and its historical development within Portugal. The results and consequences of the 1755 earthquake are outlined, and the subsequent process of reconstruction is described. All immediate measures, decrees, and proposals for the reconstruction of the city, plus Manuel da Maia's Dissertations, are carefully compared and analysed, as are the various plans proposed for the reconstruction. The preceding periods of Portuguese Architecture are studied to identify possible origins for the architecture of the Pombaline rentable buildings. Also a clear definition of the Pombaline Rentable building and the limits of the genuine Pombaline area are established. In Chapter II the general methodology used in the research is described, which includes a survey of 315 buildings and a documentary search for material relating to the construction of the buildings. In Chapter III an analysis is made of the general external and internal architectural characteristics of the rentable buildings. An extensive search for original drawings, produced drawings only of the elevations of the main streets. These are carefully analysed and compared with existing buildings and a classification system is developed. A complete survey by the author of the buildings' interiors, for which no documentary information exists, reveals a great complexity and variety of interior plans. To achieve a systematic classification of the interiors particular aspects are analysed including, the types of stairs, the organization of the interior spaces, the building location and the finishing details. Chapter IV describes some of the technical innovations shown by the rentable buildings, particularly those referring to earthquake resistance in construction and to prefabrication. During the survey of plans and elevations the Author identifies evidence for the existence of prefabrication, in terms of sizes of components, tolerances and detailing. This evidence is supported indirectly by documentary material although the extent of documentation is very limited. vii Possible evidence for an evolutionary development in the internal plan and design of the buildings based upon the position of stairs in the buildings is presented in Chapter V. An attempt is made to relate this classification to the dates of construction of the different buildings. This is achieved by an analysis of previous tax records which enable numbers of buildings constructed on different streets at different periods to be determined. Based on this analysis the evidence for an evolutionary development is discussed. In Chapter VI the Pombaline rentable buildings of Lisbon are compared with other contemporary developments at Porto Cövo, Vila Real and Manique do Intendente in order to assess the influence of the Pombaline development, both in terms of the architecture and the construction processes, on other construction projects outside Lisbon. Chapter VII discusses the principal findings of the research and their importance in the context of Portuguese architecture.

According to a recent study, about 30 percent of U.S. real estate projects are canceled midstream, while more than half run up to 190 percent over budget and 220 percent over the initial time estimate. The reasons for this are
manifold but poor decisions during the initiation and early planning of the project can be pointed to as main causes. Most poor decisions stem from lack of information, bad judgment, and lack of communication and transparency between what the client expects and what the project team can deliver. Proper
project planning procedures and methods will lead to proper contingency planning, management of partner relationships and contracts, management of dynamic change and associated risks that can, and most probably will, occur in
the course of the project.
The role of the owner cannot be overstated in all of these targets. Historically, the owners of healthcare facilities have a once in a lifetime involvement in the planning, design and construction (or major renovation) of
their facility. The interaction with planners, public bodies, architects, engineers, and other entities is a daunting prospect for which an owner will seek help from specialized firms that represent the owner.
This guide may serve as a healthcare project planning guide for owners, and in particular CEOs, to navigate the process. It will prepare the owner to recognize the major tasks and decision steps throughout project planning,
while keeping the focus on the desired outcome. Any owner should recognize that the slogan: if you dont know what you want, you will not get what you need is as true today as it ever was. This guide will include research, best practices from industry experts, and a case study on the New Orleans public healthcare planning process post-Hurricane Katrina.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2000.Includes bibliographical references (p. 311-315).
An analytical framework is developed for examining the critical characteristics of design strategies for new and renovation construction that increase the capacity of buildings to accommodate change, and for selecting appropriate design strategies for particular projects. Unlike previous building studies, this research explicitly takes into account the interactions within and between building systems and subsystems that affect the capacity of the building to accommodate change. A sample of 37 unique design strategies is identified through interviews with construction industry professionals and a review of recent literature. All design strategies and data are empirically derived and have been used in one or more buildings throughout the world. The achievements of design strategies are compared to the needs of users, to identify strategies that successfully fulfill the building user's needs over time. These achievements and needs are consistently characterized in matrix form, accounting for types of changes expected, enhanced, or enabled, building systems affected, and timeframe of expected changes. Benefits of each design strategy are evaluated over the full life of a building. Strategies with common means of increasing systems' capacities to accommodate change are compared and contrasted. Several strategies are recommended for particular building types, and for three individual case study buildings. Application of the analytical framework provides new insight into the nature of changes needed in different types of facilities, and the variety and applicability of means to achieve those changes. A building designer or facility manager could use this framework to properly select one or more design strategies that would satisfy the needs set forth by an owner for a particular project.

Full textAbstract:
The purpose of this research was to study the selection of architectural firms for 1997 and 1998 Indiana school construction projects of two million dollars or more. The study reported rankings for architectural selection criteria. Additionally, the study analyzed architectural selection procedures, architectural fees, the degree of respondent satisfaction with architectural services and the finished product, and the amount of inclusiveness in the selection.State records were used to identify the projects approved during the two-year period. Additional data were collected for 81% of the projects via surveys completed by superintendents or their designees.Major findings reported in the study include the following:1. Fees paid to architects ranged from 3.2% to 12.9% of construction costs, with the mean fee being 5.7%.2. In approximately 60% of the projects studied, respondents reported using an inclusive selection procedure for employing an architect.3. Slightly less than one-third of the projects (29%) used a direct selection procedure that precluded the use of a selection committee or the consideration of more than one firm.4. The two most frequently named selection criteria were experience in designing schools and reputation for completing projects within budget.5. The only variable found to have a significant association with the amount of fee paid was satisfaction with architectural services. Respondents in the low-fee category identified the highly satisfied response more than was expected.Outcomes suggest that a considerable number of school officials in the state did not adhere to the accepted best practices concerning competitive selection and the use of inclusive selection committees. The considerable variance in fees paid to architects was not explained by district size, district wealth, the nature of the construction project, or by the selection procedure used.Additional research was recommended in the following areas: (a) replication of the study in other states, (b) qualitative studies of superintendent attitudes about selection criteria and selection committee membership, (c) criteria for setting architectural fees, and (d) factors contributing to superintendent satisfaction. In addition, Indiana policymakers were encouraged to require local school districts to use competitive selection procedures.Department of Educational Leadership

Thesis (MBA)--Stellenbosch University, 2012.The professional team play a critical role during the design phase to ensure the implementation of a green building design, but in what way do they differ from a traditional design team? The research seeks to determine, whether the professional team members need to be specifically alert to green building principles and willing to learn and apply green building principles through an investigation of a commercial project case study. The research design embraces a qualitative approach through the gathering of data on the case study, where project information was examined and the professional team members interviewed. To reinforce the project specific information, professionals in the construction industry were canvassed for their opinions on the awareness of professional team members, and their willingness to learn and apply, green building principles on commercial projects seeking green star rating. The findings from the case study indicate that a non-traditional, integrated design approach stimulated the professional team‟s alertness and willingness to learn and apply green building principles to great success, as the project achieved a four star green rating. The survey found that professional‟s perceived green buildings to have a positive impact on the environment and if possible reverse the harmful effects that conventional buildings have on the environment. Furthermore, professional team‟s early involvement is highly imperative to achieve a green star accreditation. The green design process requires continuous input and sharing of information from all professional team members. The respondents who were surveyed indicated a positive attitude towards developing their awareness and willingness to learn and apply green building principles. Knowledge of green star rating requirements for commercial developments in South Africa as well as general green building principles, allow professional team members to gain a competitive edge over more traditional practitioners in the building sector. In addition, professional members who are aware and alert to green building are at a better position to successfully implement a green building design, consequently minimising the negative impact buildings have on the environment and ensure sustainability.

Full textAbstract:
Investigations into the behaviour of precast buildings under earthquake loading have shown that the connections are likely to be the weakest link in a pre-cast structure, and the stability of the structure under earthquake loading depends upon the strength & stability of these connections. A 2-dimensional non-linear dynamic analysis of a one storey box-type pre-cast buildings is presented. The shear walls in the buildings are modelled by linear springs, the properties of which depend upon the connections connecting the rigid panels of the shear walls.
To check the effectiveness of the NBCC code design, computer studies have been made on a box-type building statically designed for different eccentricities. The strength of the shear walls was calculated assuming that each panel was a cantilever fixed at the base with dowel bars providing the flexural steel. To make the building survive a major earthquake, we need dowel connections that can take 5mm to 6mm elongation which can be easily accommodated. Studies have also shown that under the action of an earthquake, the response of a highly unsymmetrical building will not be very different from that of a symmetric building as long as the building is properly designed using the NBCC code provisions for earthquake loading. It has also been shown that the NBCC code design eccentricity equation is somewhat conservative in calculating the design eccentricity and that a small change in the stiffness of walls perpendicular to the direction of earthquake has little effect on the response of the structures.Applied Science, Faculty of

Full textAbstract:
As spotlighted urban occurrences of significant global influence, mega-events such as the Olympics and the Expos usually create a great demand for mega-event flagships (MEFs). These purpose-built cultural, civic or sports landmarks not only serve as prominent event venues but often play a catalytic role in long-conceived renewal initiatives on a much broader scale. Lacking no successful event stories, it is not unusual to hear prominent post-event failures in MEFs. Despite its lasting appeal, such a highly controversial and challenging development has received surprisingly little in-depth analysis in existing literature. Academic interests have long concentrated on assessing impacts rather than profiling risks. Moreover, to realize such a dually oriented initiative clearly needs a competitive organization. Yet, this driving force behind becomes another understatement. Apart from tangential studies on western-based practices, pinpoint research is rare in emerging economies towards which MEFs are shifting their grounds. Such a triple imbalance may likely keep ambitious yet inexperienced hosts ignorant of tremendous risks behind overstated rewards.
To argue that MEFs should be pre-post oriented than treated simply as a legacy issue, this study presents four landmark cases of Expo 2010 Shanghai China – a mega-event as not only a crowning touch to China’s thirty-year economic rise but a catalyst for Shanghai’s renaissance towards a global center. As the centerpieces of this mega-undertaking, the Big Four (the Big4) represent the largest MEF cluster in history and the latest epitome of major projects of national significance. To explore how the Organizer has forged the sixty-year vision beyond the six-month extravaganza, participant observation is adopted due to the author’s special role as a key project coordinator of Expo 2010 during the early stages of the Big4. In gaining more useful insights for future practices, this multiple-case study takes the following three steps. First, rationales and practices of MEF development are analyzed through a historical review of eight selected cases of mega-event built legacies in five countries over 150 years. Next, programming practices of MEFs and non-MEFs in China are investigated through a pilot questionnaire survey in 2009. Finally, the 600,000-sq.m Big4 are explored respectively and collectively against the ongoing Trilogy of the Huangpu Riverfronts Renewal.
Multifold findings from previous and present cases confirm the hypothesis that MEF development is rather an issue of dualism than dichotomy. To meet existing and emerging challenges, a framework plan is developed containing four approaches and ten steps key to the vitality of MEFs. Conclusions are made from both local and global dimensions. Four major breakthroughs, two pressing problems and two emerging trends are identified for major project developments in China; whereas six essential conditions to sustain MEF development are generalized for significantly comparable cases worldwide. A timely reminder of rethinking the commitment to MEFs and a much-needed complement to related western literature, this pioneering research would be of cross-boundary value and spark interdisciplinary interest.published_or_final_version

Full textAbstract:
Estimating the construction time and cost of a building project is an essential task of construction manager, which benefits owners, engineers and contractors. Construction duration and cost, in particular, have profound influence on the outcome of a project at the conceptual stage of its life. The conventional methods used to estimate the time and costs of construction projects are based on 2D models, which need much time and effort from engineers, estimators and schedulers who are involved in preparing them because all of this process is done manually, especially when the project has several design alternatives. Considering that, Building Information Modelling (BIM), which is a technology that enhances data transfer and ensures cooperation among designers, engineers, and contractors, can provide an efficient way for cost estimating and schedule planning. On the other hand, sustainability has drawn more and more attention by the construction industry, this is because a project’s construction process has crucial impacts on society, the environment, and the economy. Modular Construction has been proven to ensure sustainable construction by reducing the negative impacts on the environment, reducing construction time, and improving manpower productivity. This research aims at developing an integrated model that interrelates BIM with construction cost estimation, scheduling, and sustainability at the conceptual design stage of projects. The aim is to reduce the preparation time and increase the efficiency of making major decisions for both conventional construction and modular construction.
The proposed model consists of five modules, including a data collection module, a cost estimation module, a scheduling module, a sustainability evaluation module, and a 5D integrated module. Plug-ins were developed in the model to link BIM tool (i.e., Autodesk Revit) with Microsoft Excel to ensure automatic data transfer among these modules all within a BIM platform so that owners and designers can quickly generate a reliable construction cost estimate, construction schedule, preliminary sustainability evaluation, as well as construction process simulation.

In this thesis, an environmentally sound and human scale set of design principles, which values ideas like environmental friendliness, human comfort and locality, is formulated, examined and justified. These principles are inspired by experiences in Latin America and South Asia and their universal significance is illustrated through case studies from several countries around the world.In the design project, these principles are applied in a local setting, in this case a residential hall on the Ball State University campus in Muncie, Indiana. The design embraces a ‘green’ approach to campus facility renovation as part of the holistic movement to make the campus more sustainable.The design focus will be on the reuse and revitalization of materials thrown away on campus. Projects in which economic limitations enhance this specific creativity serve as role models. Through the reuse of material, the renovation process of campus facilities can be linked to the recycling program and the curriculum of the university.Department of Architecture

Full textAbstract:
To build for living is to understand that built form exists only in relationship to the life that occupies it and that human life is better when it is in constant interaction with the built environment; we design it, build it, and change it as we design, build, and change our selves. Making your own place and changing it over time is an important component of living one's life to its fullest. To explore these issues, designs were made for an adaptable building type - the "mountain hut," a temporary accommodation for its wandering inhabitants. Designing it twice, as well as relocating the initial building type across the globe, from the mountains of Sierra Nevada to the Himalayas in Nepal, provided an opportunity to compare and understand the influences of local environmental and cultural conditions on the building's adaptability, as well as the level of interactivity its inhabitants could experience as they occupied and transformed the dwelling. Both designs incorporate sustainable design principles, which strengthen the overall comparison of climatic responses and the use of local materials and building technologies.Department of Architecture

As more owners seek to develop sustainable buildings, the construction industry is adapting to new requirements in order to meet owner's concerns. Material selection has been identified as an area where designers and contractors can have a significant impact on the sustainable performance of a building. Objective factors such as design considerations and cost constraints can play a role in the selection of materials. However, there may be subjective factors that could also impact the selection of materials. Building upon the potential impact of sustainability perceptions in an optimization model that can be used to help decision makers to select materials, this study defines and tests an instrument to identify and measure such perceptions. The purpose of this dissertation is to develop a conceptual instrument that measures the user-based assessment of product sustainability and validates decision-maker's perceptions in order to evaluate the contribution of subjective characteristics in materials selection. A survey of design and construction students and practitioners is carried out to capture the subjective factors included in the instrument. A Factor Analysis approach is used to refine and validate the measurement instrument and predict decision-makers' sustainability appraisal due to the factors considered.

Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: The thesis was initiated by a Consulting Engineering Company (KV3) as a research project to investigate various options in which the efficiency and energy utilisation of conventional air conditioning systems may be enhanced by using alternative and renewable energy. Initially, eight options had been identified and through a process of determining the degree of commercialisation the alternative options were reduced to three. These options, referred to as the sustainable cooling alternatives, are active mass cooling, night flushing and roof cooling system. The roof cooling system comprised a roof-pond, roof-spray, pump and storage tank. The roof cooling system was mathematically and experimentally modelled. The roof cooling experiment was performed under a variety of weather conditions with the roof-pond and storage tank temperatures continuously recorded. The experimentally recorded temperatures were compared to the temperatures generated by the theoretical simulation calculations for the same input and weather conditions. Good agreement was found between the mathematical and experimental model. The largest discrepancy found between the simulated temperature and the experimental temperature was in the order of 1 ºC. A one-room building has been assumed to serve as a basis to which the sustainable cooling alternatives could be applied to for theoretical simulation. The one-room building had four façade walls and a flat roof slab. Night flushing, active mass cooling and the roof cooling system were applied to the one-room building such that the room air temperature and space cooling load could theoretically be simulated. The theoretical simulations were also repeated for the case where the roof-pond and roof-spray were applied as standalone systems to the one-room building. The theoretical simulation calculations were performed for typical summer weather conditions of Stellenbosch, South Africa. Under base case conditions and for a room thermostat setting of 22 ºC the peak cooling load of the one-room building was 74.73 W/m². With the application of night flushing between the hours of 24:00 and 07:00, the room cooling load was reduced by 5.2% by providing 3.9 W/m² of cooling and reducing the peak room temperature by 1.4 ºC. The active mass cooling system was modelled by supplying water at a constant supply temperature of 15 ºC to a pipe network embedded in the roof slab of the one-room building. The sea may typically be considered as a cold water source for buildings situated at the coast. The active mass cooling system reduced the peak cooling load of the one-room building by 50% by providing 37.2 W/m² of cooling and reducing the peak room temperature by 6.7 ºC. When the roof-spray and roof-pond systems were applied as standalone systems to the oneroom building, the peak cooling load of the one-room building could be reduced by 30% and 51% respectively. This is equivalent to 22.3 W/m² of peak cooling by the roof-spray and 38 W/m² of peak cooling by the roof-pond. The roof-spray reduced the peak room temperature by 3.71 ºC while the roof-pond reduced the peak room temperature by 5.9 ºC. Applying the roof cooling system to the one-room building produced 46 W/m² of peak cooling which resulted in a 61.1% reduction in peak cooling load. The roof cooling system reduced the peak temperature by 8 ºC. By comparing the sustainable cooling alternatives, the roof cooling system showed to be the most effective in reducing the one-room building peak cooling load. Over a 24 hour period the roof cooling system reduced the net heat entry to the one-room building by 57.3%. In a further attempt to reduce the peak cooling load, the sustainable cooling alternatives were applied in combinations to the one-room building. The combination of night flushing and roof-spray reduced the peak cooling load by 36% while a combination of night flushing and active mass cooling reduced the peak cooling load by 55%. Combining night flushing with the roof-pond also yielded a 55% peak cooling load reduction. The combination of roofpond, active mass cooling and night flushing provided 51 W/m² of cooling which corresponded to a 68% reduction in peak cooling load. Utilising the sustainable cooling alternatives in a combination in the one-room building gave improved results when compared to the case where the sustainable cooling alternatives were employed as standalone systems. It is illustrated by means of a sensitivity analysis that the ability of the roof cooling system to produce cool water is largely influenced by ambient conditions, droplet diameter and roofspray rate. Under clear sky conditions, an ambient temperature of 15 ºC, relative humidity of 80%, a roof-spray rate of 0.02 kg/sm² and a roof-pond water level of 100mm, water could be cooled at a rate of 113 W/m². The roof-spray energy contributed to 28 W/m² whilst the night sky radiation was responsible for 85 W/m² of the water cooling. It must however be noted that the water of the roof cooling system can never be reduced to a temperature that is lower than the ambient dew point temperature.
AFRIKAANSE OPSOMMING: Die tesis is geïnisieer deur ‘n Raadgewende Ingenieurs Maatskappy (KV3) as a navorsingsprojek om verskeie opsies te ondersoek waarmee die effektiwiteit en energie verbruik van konvensionele lugversorgingstelsels verbeter kan word deur middel van alternatiewe en hernubare energie. Agt opsies is oorspronglik geïdentifiseer en deur middel van ‘n proses waarby die graad van kommersialisering van hierdie alternatiewe maniere bepaal is, kon die opsies verminder word tot drie. Hierdie opsies, ook verwys na as die volhoubare verkoelingsalternatiewe, sluit in aktiewe massa verkoeling, dakverkoeling en nagventilasie. Die dakverkoelingstelsel bestaan uit dakwater, ‘n dakspuit, ‘n pomp en ‘n stoortenk. Die dakverkoelingstelsel is wiskundig en eksperimenteel gemodelleer. Die dakverkoelingseksperiment is uitgevoer onder ‘n verskeidenheid van weersomstandighede. Die dakwater asook die stoortenk se water temperatuur is voortdurend aangeteken. Dieselfde weer- en insetkondisies is gebruik vir die simulasie berekening en die temperature van die stoortenk se water en die dakwater is vergelyk met die temperatuurlesings van die eksperimentele werk. Die temperature van die eksperimentele lesings het goed vergelyk met die temperatuur simulasie berekeninge. Die grootste verskil tussen die simulasie en eksperimentele temperatuur was in die orde grootte van 1 ºC. ‘n Een-kamer gebou is aangeneem om as basis te dien waarop die volhoubare verkoelingsalternatiewe aangewend kon word vir teoretiese simulasie. Die een-kamer gebou het uit vier buite mure en ‘n horisontale beton dak bestaan. Nag ventilasie, aktiewe massa verkoeling en die dakverkoelingstelsel is toegepas op die een-kamer gebou en die kamer se verkoelingslas asook die kamer se lugtempertuur is teoreties gesimuleer. Die teoretiese simulasies is ook herhaal vir die geval waar die dakwater and dakspuitstelsel apart aangewend is op die een-kamer gebou. Die teoretiese simulasie berekeninge is uitgevoer vir tipiese somer weersomstandighede vir Stellenbosch, Suid Afrika. Onder basisgeval omstandighede, waar die een-kamer gebou gesimuleer is, sonder enige volhoubare verkoelingsalternatiewe en ‘n termostaat verstelling van 22 ºC, is die piek verkoelingslas bereken as 74.73 W/m². Met die toepassing van nagventilasie tussen die ure 24:00 en 07:00 was die piekverkoelingslas van die kamer verminder met 5.2% deur 3.9 W/m² se verkoeling te verskaf en die piekkamer temperatuur te verminder met 1.4 ºC. Aktiewe massa verkoeling is gesimuleer deur water teen ‘n konstante temperatuur van 15 ºC te verskaf aan ‘n pypnetwerk, geïnstalleer in the beton dak, van die een-kamer gebou. Geboue geleë aan die kus kan tipies seewater oorweeg as ‘n bron van koue water. Aktiewe massa verkoeling het die piekverkoelingslas van die een-kamer gebou verminder met 50% deur 37.2 W/m² se verkoeling te verskaf en die piekkamer temperatuur te verminder met 6.7 ºC. Wanneer die dakspuit- en dakwaterstelsel aangewend is op die een-kamer gebou as enkel staande stelsels, is die piekverkoelingslas verminder met 30% en 51% onderskeidelik. Dit is ekwivalent aan 22.3 W/m² se verkoeling vir die dakspuitstelsel en 38 W/m² se verkoeling vir die dakwaterstelsel. Die dakspuitstelsel het die piekkamer temperatuur verminder met 3.71 ºC terwyl die dakwaterstelsel ‘n 5.9 ºC verlaging in piekkamer temperatuur tot gevolg gehad het. Die dakverkoelingstelsel het 46 W/m² se piekverkoeling verskaf wat ‘n 61.1% vermindering in piekverkoelingslas tot gevolg gehad het. Die ooreenstemmende piek temperatuur vermindering is 8 ºC. Deur die verskeie volhoubare verkoelingsalternatiewe met mekaar te vergelyk, word getoon dat die dakverkoelingstelsel die mees effektiefste manier is om die een- kamer se piekverkoelingslas te verminder. Oor ‘n tydperk van 24 uur het die dakverkoelingstelsel die totale energievloei na die een-kamer gebou met 57.3% verminder. In ‘n verdere poging om die piekverkoelingslas te verminder, is die volhoubare verkoelingsalternatiewe toegepas in kombinasies op die een-kamer gebou. Die kombinasie van nagventilasie met die dakspuitstelsel het die piekverkoelingslas met 36% verminder, terwyl ‘n kombinasie van nagventilasie en aktiewe massa verkoeling ‘n 55% vermindering in piekverkoelingslas tot gevolg gehad het. Die kombinasie van dakwater en nagventilasie het ook ‘n piekverkoelingslas vermindering van 55% teweeggebring. Die kombinasie van dakwater, aktiewe massa verkoeling en nagventilasie het 51 W/m² se verkoeling veskaf, wat ooreenstem met ‘n 68% vermindering in piekverkoelingslas. Deur die volhoubare verkoelingsalternatiewe in kombinasies toe te pas op die een-kamer gebou, kon beter resultate verkry word toe dit vergelyk is met die geval waar die volhoubare verkoelingsalternatiewe as enkelstaande stelsels toegepas is. Dit is geïllustreer deur middel van ‘n sensitiwiteitsanalise dat die vermoë van die dakverkoelingstelsel om koue water te produseer, beïnvloed word deur buitelug kondisies, waterdruppel deursnee en dakspuit massa vloeitempo. Onder die oop hemelruimteomstandighede, ‘n buitelug temperatuur van 15 ºC, ‘n relatiewe humiditeit van 80%, ‘n dakspuit massa vloeitempo van 0.02 kg/sm² en dakwatervlak van 100 mm, kon water verkoel word teen ‘n tempo van 113 W/m². Die dakspuit gedeelte het 28 W/m² bygedra terwyl die nagruim radiasie sowat 85 W/m² se verkoeling verskaf het. Daar moet egter kennis geneem word dat die water temperatuur van die dakverkoelingstelsel nooit verminder kan word tot onder die buitelug doupunttemperatuur nie.

It is a widely known fact that the only way to achieve sustainable development in the building sector is through green building design. The path to sustainability, however is riddled with the presence of existing buildings that are far from being efficient or environmentally practical. The way to overcome this problem is to deal with existing buildings in each city, and retrofit them to the level of being environmentally, economically and socially sustainable. This paper assesses the complete scope of retrofitting existing buildings in Hong Kong, the economic, social and environmental benefits of it, and the policy reforms to further expand its scope.published_or_final_version

Full textAbstract:
In practice, the building design process can be divided into three major stages; schematic design, design implementation and construction documents development. The majority of the time in the building design delivery process is spent in the latter two stages. Computers can greatly aid the designer in the latter two stages, by providing a tool that helps in choosing the best assemblies for a particular design and, helping in automating the process of construction detail generation. There is lack of such a tool in the architecture design domain.
In this dissertation, a novel approach for the selection and generation of building assemblies is presented. A building product model is described. In this model the building is broken down into assemblies. Each assembly has a graphical representation. By using the assemblies' representations a designer can specify his/her design concept. These assemblies are intelligent. They know how to select the correct assembly constructions for each particular design situation, based on a set of defined criteria and constraints. The different kinds of criteria and constraints that affect the selection of assemblies are identified, and examples are provided. A selection procedure is developed that can perform the selection taking into consideration the various criteria and constraints to produce a best compromise solution.
A computer prototype is developed on top of a traditional computer graphics package (AutoCAD) as a proof of concept. In the prototype, the design knowledge is encapsulated and intelligence is added to the building assemblies of a specific construction type. This intelligence allows the assemblies to be automatically selected and analyzed. Several examples of assemblies are developed in the computer prototype.
The treatment of building components as intelligent objects will significantly increase the efficiency of design in terms of economy and performance. This is because issues related to the specific design can be addressed in an organized way. Issues like cost, constructability, and other performances can be taken into consideration at the design level. The approach described here provides a more efficient and time saving way for selection of building assembly constructions.Ph. D.

Full textAbstract:
This study proposes a specification for an assessment tool that integrates sustainable development into briefing and design processes of buildings in developing countries. The building and construction industry have a significant role to play in supporting sustainable development in developing countries. However until the implications of sustainable development for the building and construction industry in developing countries are understood and interpreted into a plan of action, little progress can be made. The research proposal aims to make a contribution to knowledge within the field of sustainable development and building and construction in developing countries. The study suggests that an effective way of beginning to integrate sustainable development into building and construction is to make sustainable development an explicit goal during the briefing and design process of the building. The study develops a specification for assessment tool that enables the goal of sustainable development to be interpreted into building and construction objectives and shows how this can be used in the briefing and design processes of buildings. The study is based on both a qualitative and quantitative approach. Through critical review of literature and inductive analysis key concepts pertaining to sustainability, sustainable development, developing country contexts, assessment frameworks, and building and construction are defined. These are compared and analysed to formulate a specification for an assessment tool. In order to test and validate findings the specification is compared with an existing building assessment tool, the Sustainable Building Assessment Tool. All hypothesis developed by the study are successfully demonstrated and the study is successful in proposing a specification for an assessment tool that integrates sustainable development into briefing and design processes of buildings in developing countries.Thesis (PhD(Architecture))--University of Pretoria, 2004.

Full textAbstract:
The purposes of this study were: (1) to study the conditions that influenced the construction of early rural schoolhouses in Indiana, (2) to examine how emerging concerns for sanitation and student health surfaced from the construction of early rural schoolhouses, and (3) to provide a data base for individuals who desire to do further research on school buildings and their historic preservation. The research concentrated on the period of 1875 to .1915. Special attention was given to conditions that led to the passage of the Sanitary Schoolhouse Act of 1911.Results revealed that early schoolhouses often were constructed as little more than shelters. Virtually no consideration was given to either educational processes or the health and safety of occupants. As a result, water and other design and care of water and sewage systems resulted insanitary factors became major concerns. The inadequate serious health concerns for students and teachers. These concerns contributed to the passage of laws that eventually led to: (1) the abandonment of early rural schoolhouses, and (2) the construction of more sophisticated structures often designed by professional architects.This study also revealed that some of those early schoolhouses that survived have been converted to residential, business, or civic purposes. Photographs of such buildings in Boone, Hamilton, Hancock, Hendricks, Henry, Madison, and Tipton counties in Indiana are included in the thesis. They provide evidence that preservation is a means with which these buildings can continue to serve a useful existence.There is historical value in understanding conditions that led to the rise and fall of early rural school buildings. Collectively, data about the construction and sanitary conditions provide insights into rural culture, expand an appreciation of the uniqueness of design for these buildings, and enhance the importance and desirability of preserving these structures. The net product of this thesis is to provide a view of the construction of buildings in central Indiana of this period.Department of Architecture

Full textAbstract:
Although requirements in relation to indoor environment quality (IEQ) have been made in green building rating systems such as LEED (Leadership in Energy and Environmental Design) and China GBL (Green Building Label) to promote occupant comfort, health and productivity, in practice, very little is known about user perception and satisfaction with IEQ in green buildings. Recruitment and post-occupancy evaluation of 10 office buildings (8 green buildings and 2 non-green buildings) and their 696 occupants for this study generated a dataset representing many potential avenues of inquiry. From the occupant’s point of view, the green offices in buildings with whole-building certification were significantly more satisfactory than the non-green offices, whereas the green offices certified only on the basis of their interiors were comparable to the non-green offices. Mixed-mode ventilation performed much better than other ventilation types (central air-conditioning and split air-conditioning). However, the mixed-mode green buildings were invariably perceived to be too cold in winter. A correlation model showed that green building users tended to appreciate a well ventilated, daylit, and quiet indoor environment for their health and productivity. The findings in the study made critical suggestions with regard to pursuing green building certification and addressing human factors in sustainable building design and research. The strengths and weaknesses of this study were discussed to inform future studies.published_or_final_version
