Full textAbstract:
Building energy certification is stipulated by law in the majority of the European countries. The intention of these regulations is to offer key performance indicators (KPIs) to relevant and interested stakeholders. Another motivation for implementing these calculation schemes was to compare the energy performance of different buildings. However, existing guidelines for building energy evaluation do not comprehensively outline the input data collection process and the derivation of substantial KPIs. Furthermore, practitioners do not share a common understanding of the approach to energy certificates, resulting in different practical methods and different interpretations of the calculation guidelines. As a result, the envisioned comparability between buildings is not ensured, as a number of studies illustrated in the past.This contribution focuses on a specific uncertainty in building energy evaluation input data, pertaining to zoning and usage assumptions. Toward this end, two case studies are presented. A number of existing buildings (typical Viennese building stock) were subjected to the Austrian normative energy certification calculation. Thereby, different scenarios regarding the zoning and usage profiles of the buildings were developed. On the one hand, the calculated performance of individual (residential) units was compared with the calculated performance of the whole building. On the other hand, calculations considering different usage assumptions in different zones within the building (detailed calculation) were compared to results based on generalized assumptions for the whole building. The evaluation of the case study buildings showed significant differences in KPIs, given different input data (depending on the case study, heating demand showed deviations up to 50%). The results emphasize the importance of a clear documentation of input data assumptions for building-related energy assessment.

Full textAbstract:
As a result of an increasing demand for energy-efficient buildings with a better experience of user comfort, the built environment sector needs to consider the prediction of building energy performance, which during the design phase, is achieved when a building is handed over and used. There is, however, significant evidence that shows that buildings do not perform as anticipated. This discrepancy is commonly described as the ‘energy performance gap’. Building energy audit and post occupancy evaluation (POE) are among the most efficient processes to identify and reduce the energy performance gap and improve indoor environmental quality by observing, monitoring, and the documentation of in-use buildings’ operating performance. In this study, a case study of UAE university buildings’ energy audit, POE, and dynamic simulation were carried out to first, identify factors of the dynamic energy performance gap, and then to identify the utility of the strategy for reducing the gap. Furthermore, the building energy audit data and POE were applied in order to validate and calibrate a dynamic simulation model. This research demonstrated that the case study building’s systems were not operating as designed and almost a quarter of the cooling energy was wasted due to the fault of the building facility management of the mechanical systems. The more research findings were discussed in the paper.

Salt damage can affect the service life of numerous building structures, both historical and contemporary, in a significant way. Therefore, various conservation methods have been developed for the consolidation and protection of porous building materials exposed to the salt attack. As any successful treatment of salt damage requires a multidisciplinary attitude, many different factors such as salt solution transport and crystallization, presence and origin of salts in masonry, and salt-induced deterioration are to be taken into account. The importance of pre-treatment investigations is discussed as well; in a combination with the knowledge of salt and moisture transport mechanisms they can give useful indications regarding treatment options.Another important cause of building pathologies in buildings is the rising damp and this phenomenon it is particularly more severe with the presence of salts in water. The treatment of rising damp in historic building walls is a very complex procedure. At Laboratory of Building Physics (LFC-FEUP) a wall base hygro-regulated ventilation system was developed. This system patented, HUMIVENT, has been submitted to laboratorial monitoring and to in situ validation and a numerical simplified model was developed to facilitate the practical application. Having in mind the practical application of scientific and technological knowledge from Building Physics to practice, this paper presents the design of the system (geometry, ventilation rate and hygrothermal device), the detailing and technical specification of its different components and information about the implementation in three types of buildings: a church, a museum and a residential building.

Conservation of heritage buildings has become a very important issue in many countries, as it is in Italy, where a great number of existing buildings of historical–artistic importance are seismically vulnerable. To improve existing building behavior, researchers focus on the design of retrofit interventions. This paper presents the application of energy dissipation devices in the retrofit of two existing Reinforced Concrete (RC) buildings, both irregular in plan and along their heights, designed for gravitational loads only. These buildings are representative of Italian public housing built in the 1960s and early 1970s. Technical information and mechanical properties of materials are presented, and non-linear analyses are carried out to evaluate the buildings’ behavior under earthquake loads. Many of their structural members do not satisfy the verifications required by the Italian Building Code. Retrofit interventions with buckling-restrained axial dampers in one building and viscous fluid dampers in the other are proposed. The verifications of the retrofitted buildings and the amount of the energy absorbed by the devices with respect to that absorbed by the unretrofitted buildings show the effectiveness of the proposed interventions. Moreover, it is demonstrated that adequate dispositions of the dissipative devices in plan and along the height increase the torsional stiffness of the buildings, improving their structural response under seismic action.

This paper presents the negative impacts on residential buildings in Kosovo, - as well as the main factors of the occurrence of sick building syndrome (SBS) in residential buildings in the case of Kosovo. It also examines the impact of different materials on this phenomenon and how many constructions in Kosovo are protected from this phenomenon. For the assessment of the impact of materials on health and the environment, it is necessary to consider all the phases. Starting from the phase of construction, selection of materials, application from the beginning of the use of the building, including all the materials processing from the beginning until their application, the use of natural resources for the production of various construction products, the necessary energy for the production and processing of the materials used, and the amount of release and imitation of CO2 (carbon dioxide). This paper also discusses the question of what sick building syndrome SBS is, how materials are affected by this phenomenon, what are the main materials affecting the residential buildings in SBS phenomenon in Kosovo, what buildings are affected by this phenomenon and how does this phenomenon affect human health. Furthermore, this paper provides a deep analysis on factors influencing the phenomenon of SBS in different municipalities and several companies. It also discusses the influence of Asbestos and its impact on SBS, through a survey conducted in different municipalities and institutions and other companies. Through this discussion the paper attempts to provide information on the current knowledge about asbestos, as well as the manner of its assembling and dismantling, storage and all other information related to this material which has a great impact on the appearance on phenomena of SBS. A special emphasis has been put on the impact of materials on our health, recent research on the materials used and impact on the appearance of SBS case, including the diseases that occur as a consequence of the occurrence of diseased buildings.

Full textAbstract:
From the 19th century onwards, glass has been used intensively in buildings. During the design process, the importance of aesthetics is very common for architects in general. The application of glass walls as part of the building’s structure has given flexibility in design together with transparency as well as aesthetics. Structural glass systems have been used in different building types for example office, residential, educational, commercial, transportation, cultural … Beyond the high - rise and high - tech buildings, structural glass systems have been applied also to historic buildings during their conservation process. The adaption of the structural glass system and the opportunity to reuse the existing building are other important aspects to be discussed. In this article, the literature review will be formed with a brief explanation of transparency in contemporary architecture, structural glass systems focusing on ‘suspended glass systems with pre-stressed cable trusses’ (SGSPCT) which has three application methods; 1) between floor systems 2) independent body systems 3) distance bridging systems and the reusability of existing buildings. The ‘between floor system’ which is commonly used as a contemporary solution technique for historic buildings together with its effects, will also be analysed with the help of a case study, Esma Sultan Mansion. This historic building’s present glass structure will be studied to create an alternative proposal less dependent to the existing building. Another case study will be the Ballapais Abbey. Part of this gothic building (the common room) that has collapsed in the past will be analysed. An independent glass structured annex designed with SGSPCT will be proposed giving joint details of the adaptation to the existing building. This case of study is a literature analysis based on books, internet resources, articles and architectural drawings, like plans, sections and details related to the buildings. Both case studies will be proposing an alternative glass structured annex that is focusing on gained transparency and reusability in respect to the existing historic building.

Each historic building or cultural heritage site requires proper care at every stage of its life cycle. Appropriate interventions aim to prevent building disasters and preserve invaluable cultural objects from ageing or deterioration processes. This article is a case study of mistakes made in various phases of a building’s life—in the design, execution, and use. The work aims to point out various aspects of the errors made during the building’s restoration. The conducted material research, computational analyses, laboratory tests, and documentation studies comprehensively consider the presented examples. The structural analysis of the buildings consists of its load-bearing capacity and its stability.

International Journal of Structural Integrity 9, no. 1 (February 5, 2018): 38–49. http://dx.doi.org/10.1108/ijsi-03-2017-0018.
Full textAbstract:
Purpose The purpose of this paper is to study the method of hysteresis energy distribution and maximum relative lateral displacement in buildings’ stories, under the influence of scaled records for near-fault and far-fault earthquakes. The bracings in the considered buildings’ plan are distributed in two different ways: in the first case, the braces are added in external frames of the building, and in the second case, in the internal ones. Design/methodology/approach This research first selects some steel buildings with concentric braces and studies the seismic vulnerability of buildings under different earthquakes in accordance with the concepts of input and Hysteresis energy. In order to study the impact of braces’ distribution in the building’s plan, the buildings were modeled in this study in two ways. In the first way the braces were added to the building’s external frames and in the second way in its internal ones. Findings Results show that the need for far-fault scaled records’ displacement is more than the near ones and that the resultant relative lateral displacements in buildings with external braces are more than those with internal ones. Originality/value After these studies on the way of hysteresis energy distribution, it was shown that in case of buildings with internal braces, as the building’s height increases, the share of higher stories of the hysteresis energy rises. Also, it was illustrated that hysteresis energy distribution in buildings with internal braces is more uniform than those with external ones.

Full textAbstract:
Flex−buildings are buildings which are literally designed to change. A flex−building must be able to accept different infills and its users must be able to easily adapt their surroundings. Flexibility is defined as the capacity of a building to undergo modifications and accept changes of function with limited structural interventions. More than 40% of the activities housed in a flex building can continue to function during modification. Studies into flex−buildings (commissioned by the Dutch Government) have elicited a number of insights. These are not hard−and−fast conclusions but more in the region of statements and reminders for those involved with flex−buildings. These studies show that it takes more than civil engineering to successfully realise such buildings. Aspects of use and management are at least as important. Besides, it requires designers who are willing to let go of their design after it is finished. For the result is not a completed ‘architectural’ product but a continually changing object. Following insights (among others) will be illustrated with built and unbuilt projects in the Netherlands. • The façade design, for example, figures prominently in designing flexible buildings. It makes special demands on the design’s presentation during the design process, as the building can assume different appearances over time. The double facade is a promising concept that allows for expressive and/or open facades in flexible buildings. It can also help to reduce a building’s energy consumption. • Also by deliberately incorporating excessive space and construction a building has the necessary leeway to accommodate future developments. A building’s flexibility is enhanced by oversize in structure as well as space. • A big multi−use building in Rotterdam (H. A. Maaskant / W. van Tijen (1951)) and recent projects of RUIMTELAB are presented as case−studies. These are an inspiration for architects and planners looking for design tools to help achieve an open architecture.

Full textAbstract:
The paper presents results from an experimental program implemented for three representative buildings in Bucharest metropolitan area and aimed to explore the potential of various dynamic identification methods in providing information about building state changes. The objective is to establish reference values of potential use in rapid earthquake damage detection systems. Each of the selected buildings was designed according to a different seismic code, in force at the time of its construction. The methods employed for this study were: the analysis of Fourier spectra, the analysis of the transfer function and the random decrement technique. To validate the results, the fundamental periods of vibration determined experimentally were compared with the corresponding values predicted by the empirical formulas specified in the corresponding editions of the Romanian seismic code. The results revealed consistent values for both the fundamental period and the damping ratio of the buildings. However, small variations of the two parameters were identified, depending on the time the recordings were performed, noise sources and levels and building occupancy. The results, in terms of validated data on the dynamic characteristics of Romanian building stock and of assessment of methods performance, add up to the information pool needed for the development of countrywide pre- and post-earthquake assisted decision tools.

Buildings are the only resource growing constantly. Although relevant data for Serbia is not available, it is presumed that even more than 50% of energy production is spent on buildings in our country. This conclusion is based on two facts: the present industrial production and the state of buildings. In order to establish measures for energy efficient refurbishment, one residential building was analyzed in Belgrade. The chosen building represents the construction period when application of thermal insulation was not obligatory according to building regulation. As more than 35% of buildings were built in that period, they represent great potential for energy savings through the process of refurbishment.

Purpose – Scotland’s built heritage (pre-1919 building stock) is exhibiting varying levels of disrepair, in particular for stonemasonry works, despite the government’s on-going efforts for promoting higher standards of repair and maintenance (R & M) of historic buildings. The purpose of this paper is to examine the problems associated with the R & M of historic buildings. Design/methodology/approach – Two case studies (Projects A and B) exhibiting critical disrepair are reported. Site surveying was carried-out on both projects, to identify site features and R & M problems along with proposed solutions drawing on the lead author’s extensive industry experience as a stonemasonry consultant. Three semi-structured interviews were conducted with professionals involved in each project to elicit views on the challenges faced. Additionally, three industry experts were interviewed to provide a wider perspective of the R & M challenges facing historic buildings. Findings – Neglect and poor practice resulted in both projects becoming more challenging and expensive than they needed to be, which was attributed to generic and advanced skills 6deficiencies of the workforce. There is an urgent need for a multi-disciplinary approach to the development of a method statement for R & M, drawing on the expertise of professionals and contractors, particularly when specifying repairs to structural elements. Originality/value – This paper has provided original and valuable information on R & M problems, highlighting the importance of continued investment in skills development for historic building R & M to enhance existing current training provision and practice. There is a need for further similar project-based data to inform skills development strategies for the R & M of historic buildings as well as enhancing existing qualification frameworks.

In 1987, the Brundtland report defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The 30 percentage of the whole world greenhouse gas per year come from buildings. In many situation when architects design tall buildings, they often take into more consideration operational efficiency instead of some influence of environment. The consumption of energy ascend dramatically in developing counties, which leads to air pollutions and increase of greenhouse gas in these countries. In China, the number of tall buildings are increasing and these tall buildings take large proportion of energy consumption. The number of tall buildings was 400 until 2000 and the energy consumption of huge tall buildings is 6 to 8 times more than common buildings. Therefore, how to reduce energy consumption in tall buildings plays a vital role in sustainable development. The holistic sustainability includes three aspects which are economy, society and ecology. The purpose of this essay is critically assessing sustainable tall buildings in China and UK. Then limitation of holistic sustainability of building scale in China would be analyzed and how to enhance it.

The conservation of historical timber structures requires both the knowledge of structural behavior of complete building and behavior of any single element in structure. Because of a poor communication between the institutions involved in the conservation and restoration of buildings and institutions that urgently require renovation of structures, renovation of historic buildings is often performed inappropriately due to engineering and architectural approach. Buildings are frequently subjected to inappropriate interventions, replacements of structural elements, or even worse, they are demolished. First case study in this paper is Cathedral from Gospic city which was subjected to inappropriate reconstruction in 1990s. Second case study is small traditionally constructed timber chapel in village Lijevi Stefanki which represents a valuable monument of rural cultural heritage.

In the context of exploring and implementing China's new urbanization, green eco-city have become a transformation model for urban development. Sharpening green buildings in the construction industry can significantly influence and determine China's economic growth trends, as well as the growth and overall development of its national economy. However, current green eco-city still lack appropriate standards and scientific theoretical basis to determine the target star program of green buildings. To fully implement the green building standards, establish and improve a sound technical standard system for the construction of green building demonstration areas, this study considers the spatial layout of green buildings as the core, adopts a plot potential evaluation method for evaluating a few green building plots, and utilizes four factors in verifying plots with great star potential. The study also establishes a system to calculate the star proportion of green buildings and applies the system in calculating the green building ratio of GM New District. Results indicate that the system can quantitatively analyze a plot potential, calculate the star proportion of green buildings scientifically and rationally, and provide some references for the construction of eco-city and the preparation of special planning for green buildings. The system construction is conducive to provide technical support for the construction of green eco-city. The improved system can be applied in the green building demonstration areas in China, and will be a reference model of constructing green building demonstration areas in the country.

National heritage buildings are considered as the memory of the cities and its civilization’s legacy. Such buildings are receiving more attention these days especially from architectures who are trying to restore them by using the proper techniques to bring them back to their former appearance to serve the community in the present time. From that point, the general goal of this research is to concentrate on the used techniques of restoring national heritage buildings by using the proper materials for the damaged or the collapsed parts as the restoration process differs from a building to another. All these points should be done according to the laws and protocols of UNSCO and ICOMOS to keep the authentic features of the building and pass it on to the next generations. This research deals specifically and practically with restoring the Qishla building in Kirkuk as a restoration sample. Some parts of that building collapsed recently and the research aims to save that building by studying the techniques of restoring it using the materials and building techniques of the era the building was built in. This research rises an important point, which is finding a general prospective of scientific and technical ways in restoring cultural heritage buildings which are made from stone specifically. From all that above the main issue that this research deals with is “The unclear techniques of restoring cultural heritage buildings in general and the restoration process of Qishla building with stone in specific”. Accomplishing the aim of this research lies in two points: First: Studying the rules which govern the restoration process of cultural heritage buildings. Second: Studying the restoration process of Qishla building and that includes; the restoration process with stone should be done by examining the chemical and physical features of the stone, durability of the used stone, conducting chemical tests in international labs as (ACMAE ANALYSES/ Canada) and the last step is to analyze and discuss the results to take final decisions.

This study investigates the energy and cost performance of thirtyrecent buildings in Melbourne, Australia. Commonly, buildingdesign decisions are based on issues pertaining to constructioncost, and consideration of energy performance is made onlywithin the context of the initial project budget. Even where energyis elevated to more importance, operating energy is seen asthe focus and embodied energy is nearly always ignored. Forthe fi rst time, a large sample of buildings has been assembledand analysed to improve the understanding of both energy andcost performance over their full life cycle. The aim of this paperis to determine the relationship between energy and cost usingregression analysis for a range of building functional types.The conclusion is that energy and cost are strongly correlated,independent of building area, and equations are presented forfuture modelling of energy using cost as the independent variable.

The residential sector is one of the largest energy-consuming sectors in Taiwan. Taiwan applies building codes and appliance standards to reduce the total energy demand for buildings, especially for façade design. Some research studies demonstrate that design decisions regarding the envelope shape have a direct effect on a building’s energy performance. This paper presents a comparative study of four façade design strategies for low-rise residential buildings by combining energy performance and architectural creativity. The research aims to provide insights for Taiwan’s building designers and energy policymakers and to provide an overview of façade standards for residential buildings in urban areas that is not only innovative in design but also has an energy-saving potential. The approach used in this research combined the overhang and side fin shading design with an open plan, which allows for optimum daylight exposure across all spaces in order to reduce energy consumption.

Current studies have discussed the significance of building orientation to the building indoor micro-climate and highlighted the need for more empirical research in other to establish the best orientation for buildings. Other scholars have argued that the impact of building orientation is insignificant and varies from one climatic region to another. This study, therefore, examines two prototype classroom buildings at the Kafanchan campus of Kaduna State University –Nigeria. The main purpose of the study is to determine the effect of building orientation on the indoor micro-climatic performance of two classroom buildings. Three Hobo Weather Data Loggers (HWDL) were used to collect data in the selected case-studies, and the third one was used as a benchmark. The study showed a remarkable difference in the indoor microclimatic conditions of the two buildings. The air temperature in case-study (B) is 1oC to 2oC lower than that of case-study (A) in all the respective time intervals. Also, 2% to 4% relative humidity difference was observed in favour of case-study (B). In conclusion, case-study (B) has demonstrated a more favourable indoor micro-climatic performance than case-study (A), and future simulation studies towards understanding the indoor micro-climatic performances of all possible building orientation options such as North-East/South-West, North-West/South-East, North/South and East/West in other to ascertain the optimum option are recommended.

Full textAbstract:
This study investigates the energy and cost performance of thirty recent buildings in Melbourne, Australia. Commonly, building design decisions are based on issues pertaining to construction cost, and consideration of energy performance is made only within the context of the initial project budget. Even where energy is elevated to more importance, operating energy is seen as the focus and embodied energy is nearly always ignored. For the first time, a large sample of buildings has been assembled and analyzed to improve the understanding of both energy and cost performance over their full life cycle, which formed the basis of a wider doctoral study into the inherent relationship between energy and cost. The aim of this paper is to report on typical values for embodied energy, operating energy, capital cost and operating cost per square metre for a range of building functional types investigated in this research. The conclusion is that energy and cost have quite different profiles across projects, and yet the mean GJ/m2 or cost/m2 have relatively low coefficients of variation and therefore may be useful as benchmarks of typical building performance.

Full textAbstract:
The earthquake that shook Mexico City on 19 September 1985, destroyed several hundred buildings and took thousands of lives. Two buildings located in the most highly damaged part of the city experienced strong shaking, but suffered only slight damage. These reinforced concrete frame buildings had been retrofit with steel bracing systems and infill reinforced concrete walls prior to the earthquake. Forced vibration tests, analytical studies and geotechnical investigations for each building have been conducted. The results indicate that the steel bracing systems strengthened the buildings and stiffened them, moving their natural periods away from the 2.0-second predominant ground period in that part of the city. Implications for the design of strengthening systems have been determined.

Purpose – The purpose of this paper is to identify the most influential buildings elements in term of the cost for timber restoration works. Design/methodology/approach – The research employed the case studies methods with questionnaires surveys. Two case studies were chosen and questionnaire surveys were distributed to contractors and consultation companies. The cost was identified based on the elemental cost analysis of historic timber buildings. Findings – The restoration of historic timber buildings in Malaysia has grown rapidly, especially in the UNESCO world heritage sites, Melaka and Penang. Data obtained on the restorations of timber buildings show that the most influential elements were upper floors, roofs and walls. Termites’ invasions and the lack of building analysis were found to be the major issue in timber restoration works. In addition, the availability of timber material contributed significantly to the increase of cost for restoration works. Originality/value – The cost for every element was identified and was used as a reference for new restorations projects of historical, timber buildings. This paper also highlighted the causes for the problems and the factors affecting the cost of timber restoration works. These data are useful information, especially for surveyors and contractors who are involved in the restoration of historic timber buildings. Maintaining or replacing these elements with other material can help to minimise the restoration cost of timber buildings in Malaysia.

Passive solar control solutions have been widely used in buildings in tropic countries like Malaysia. It is assumed that these solutions may notably control the heat-gain of buildings. However, there is a lack of empirical studies that assess the extent of green-glazed techniques to sufficiently control solar heat-gain. The current study uses a case study approach to examine the thermal indoor performance, particularly the near-glazed workplace area. The performance of the ST Diamond Building (in Putra Jaya, Malaysia) has been examined in terms of: outdoor/indoor dry bulb temperature; glass surface temperature; heat flux through glazing; outdoor/indoor air movement; lux and; solar radiation. The results of the field analysis indicated that ST Diamond Building’s green-glazed solutions are efficient to control solar heat gain, which in turn will lead to reduce energy consumption for controlling solar heat loads.

Full textAbstract:
Office buildings built before the entry into force of the first thermal regulation in 1991 constitute a relevant group for analysing the energy performance of the Portuguese building sector. A dynamic energy simulation was used to assess the energy performance of an existing office building located in the town of Bragança, Portugal. Four energy efficiency measures were selected and a financial evaluation through the internal rate of return (IRR) method was undertaken to choose the best retrofit option for improving the building’s energy performance. An investment package consisting of the roof insulation and a new equipment for the domestic hot water system presented an IRR higher than the discount rate used in the analysis, and, thus, a positive financial return. The results of the study also suggest that the EU’s comparative methodology framework is not particularly suitable for assessing building retrofit investment at the private investor’s perspective and further refinement in the cost-effective approach to renovations is needed to help stimulate building’s energy renovation market. Suggestions for further studies conducted for office buildings in the different climate zones in Portugal are also proposed.

Full textAbstract:
The buildings and construction sector accounts for the majority of the energy consumption in the Kingdom of Saudi Arabia (KSA). For a sustainable future, energy consumption in the sector should be reduced and existing buildings need to be energy retrofitted. A number of studies present energy retrofitting of residential buildings in KSA; however, there is a lack of studies presenting retrofitting of educational buildings. Thus, the aim of this study is to adopt a BIM-based approach to assess Energy Conservation Measures (ECMs) in a prototypical Government-built educational building in Dammam, KSA. The methodology consists of six prime steps, (1) case study data collection, (2) energy auditing, (3) proposing ECMs, (4) BIM model development, (5) energy assessment, and (6) economic assessment. The energy audit revealed several inefficiencies in the building construction and operation and four ECMs were proposed and simulated. It was found that annual energy consumption can be reduced by 22.7% in the educational building, and the investment for the four ECMs is paid back in 2.7 years only. Therefore, implementing the proposed ECMs is a viable option to energy retrofit such educational buildings in the country, and the presented BIM-based approach can be adopted to efficiently conduct the energy retrofitting process.

Full textAbstract:
Buildings contribute around 45% of the world's energy consumption. Reducing energy demand in buildings therefore plays a vital role in addressing the depletion of energy resources and associated environmental issues. Previous research explored the optimisations of the costs and energy consumption of buildings, but often overlooked the connections, tradeoffs and synergies between them. The aim of this paper is thus to develop a theoretical model of the influencing parameters of the life cycle cost-energy relationship (LCCER) of buildings using the Political, Economic, Socio-cultural, Technological, Environmental and Legal (PESTEL) analytical framework. This study was carried out through a critical literature review, model development and validation through case studies with four zero or nearly zero energy building projects carefully selected from the European Union and Australia. The developed model addresses the buildings' LCCER by identifying the key influencing parameters and explicating the mechanisms (namely, the simultaneous and unilateral effects) by which the identified parameters affect such relationship. The important influencing parameters were found to reside in two aspects: (1) internal project designs covering building characteristics, building structure and function, and construction process, and (2) external environments covering climate, economic condition, occupant behaviour, policy and regulation, and buildings' lifespan focused in the studies. Various statistical correlations were found to exist between the costs and energy consumption of the studied cases. It is summarised that these correlations may be attributable to the synergy between the simultaneous and unilateral effects of the identified parameters. The developed model contributes a systemic approach to examining the building's life cycle economics and energy in a comparative manner.

Full textAbstract:
In the rapidly growing economies of Southeast Asia, energy consumption and energy costs in buildings continue to increase. Over the past decade, energy consumption from the commercial building sector in Thailand has increased at an average of 4% per annum and currently represents over 30% of total electricity consumption, second only to the industrial sector. Buildings that exist today will continue to represent most of both energy and greenhouse gas (GHG) emissions from the built environment, with newly constructed buildings representing only a small additional portion. This paper analyzes the environmental, technical, and financial characteristics of energy efficiency retrofit activities in commercial buildings in Thailand through detailed case studies of forty-two projects undertaken over the past 8 years. Our findings suggest that retrofits provide significant opportunities to reduce energy use, energy costs, and GHG emissions while also validating the economic feasibility of investments into such retrofit activities. Through this detailed analysis of past retrofit projects in Thailand, we found that the marginal abatement costs (MAC) relating to the key energy conservation measures (ECM) implemented within these retrofit projects all have negative costs. However, although these findings demonstrate positive economics and should be sufficient to instigate widespread adoption, in reality, this is not taking place. It is evident that greater public policy and leadership are needed to stimulate growth in the building retrofit sector to take advantage of the opportunities and benefits that building retrofits offer.

The adaptation of post-industrial building allows for solving problems connected with the protection of relics and is useful in the process of providing order to the cultural landscape. However, the adaptation of historic buildings is associated with many problems. At the same time, the conservation, architectural, construction, technological requirements and the investor's ideas must be met. Meeting all conditions at the same time is a difficult task, but possible. The change in the way that a historic building is used requires a series of preliminary studies of the building to be carried out. The article presents the results of the diagnosis of the technical conditions preceding the adaption of a former factory in Zielona Góra.

Energy consumption in buildings varies considerably depending on type and usage. However, monitoring and regulation of electrical power consumption due to user-related activities are not presently embedded in current English Building Regulations. These energy uses include lifts, server rooms, and small power loads, and are collectively referred to as unregulated energy usage. As part of a larger study of unregulated energy usage in university campus buildings, this paper describes the development and demonstration of a methodology for quantifying unregulated power usage using Building Energy Management System data for a case study university. The methodology was applied to four different buildings. This approach was applied to a Chemical Laboratory, a Physical Science Laboratory, a Library and an Administration Office. The results obtained revealed that electrical consumption was consistently much higher than traditional benchmarks suggest as being normal, particularly within the laboratories. Additionally, within the specific unregulated electricity case study, four rooms in the Physical Science Laboratory indicated very high unregulated electricity usage figures, averaging at 89 kWhm−2 per annum across just four rooms. Practical application: Unregulated energy research, within the Higher Education Sector, is undeveloped. Previous literature focuses on specific areas of unregulated energy, such as equipment usage. However, analysis based on different room types has not been completed on a wider scale. Hence, there is a gap in the current research. This research shows analysis of unregulated energy in different university buildings. It develops a methodology to further understanding on this undeveloped area. Additionally, it advises that unregulated energy must be calculated during a building’s design stage. By using a selection of case studies, this research furthers understanding on the overall effects of unregulated energy.

Over the past four decades, building modeling has taken numerous forms utilizing available technologies and software. Building information modeling (BIM) has significantly developed with the continuous advancements in the information technology and hardware industries. The evolution of BIM has attracted many researchers to explore its possible applications in modeling buildings and facilities with a humanitarian heritage value. However, researches have not been limited to that, as they later expanded to test the applicability of BIM in progressing the fields of maintenance and rehabilitation, operation and management, and even checking the durability of such buildings against varying circumstances and usability as well. As a result of a deep literature review, this research is developed to provide a critique of the previous studies conducted on the fields of heritage building information modeling (HBIM), the relevant software and equipment used in those studies, as well as case studies and applications used to demonstrate HBIM capabilities. Also, two case studies of Qasr Al Farid and Al-Bugiry buildings in KSA were implemented in this research to demonstrate the capabilities of HBIM in preserving the heritage value of historic buildings and monuments and to provide possible means of archiving the heritage value of those buildings utilizing state-of-the-art technologies. This study is expected to aid governments and decision makers of heritage buildings in understanding the positive impacts of including the HBIM in their management and operational processes, and will also act as a beneficial guiding tool for academic researchers to identify the gaps and limitations in previous studies to work towards overcoming them.

This paper presents a number of case studies related to the strengthening of concrete and masonry structures damaged by the April 6, 2009, Mw 6.3 earthquake that struck the Italian city of L’Aquila and surrounding localities. After a brief overview of the existing challenges in buildings constructed prior to 1972 when the first building code addressing seismic construction was enacted in Italy, the paper describes interventions using technologies that can be considered innovative in that they are not addressed in the majority of the current building codes worldwide. The following strengthening methods are described: a) fiber-reinforced polymer (FRP) composites in the forms of manual lay-up, procured laminates and spikes; b) steel-reinforced polymer (SRP) lay-up and spikes; and, c) fabricreinforced cementitious matrix (FRCM). The paper concludes with a description of how the deployment of innovation for construction takes place in the United States. This example is intended to identify challenges to innovation and a possible method to overcome them.

Purpose Historic buildings can make a significant contribution to the history and culture of a country. Today, land scarcity has led to the demolishing of existing buildings to meet the demand for new constructions. Adaptive reuse of buildings (ARB) while preserving the hidden prestige of historic buildings plays a pivotal role in regenerating the built environment to cater to the demand that exists for new buildings. Sri Lanka has so far not embraced ARB, which can help to preserve the historical and cultural values of the existing building stock in the country. Hence, the study aims to analyze the remedial actions that can overcome the barriers to and challenges of ARB in Sri Lanka. Design/methodology/approach This study adopted a qualitative research approach by using three expert interviews and five case studies. The data collected from the case studies were analyzed using content analysis. As a part of the case studies, semi-structured interviews with 15 professionals who are already practicing ARB were conducted. Findings When making the ARB decision, key drivers and parameters of ARB have to be considered. ARB has socio-cultural, environmental and economic benefits. Sri Lanka as a developing country will definitely face barriers and challenges when adopting ARB. These barriers/challenges could be categorized as social; environmental; economic; legal-regulatory; and physical-technical-other barriers/challenges. The economic barrier, “Higher opportunity costs,” and the legal barrier, “Health and safety requirements,” stipulated by the authorities were common to all five case studies. Originality/value The study identifies the actions that can overcome ARB barriers and challenges present in Sri Lanka to reap maximum socio-cultural, environmental and economic benefits.

Progress does not amount to destroying the future, but to preserving its essence, to generate the impetus to do it better today (Y. Ortega Y Gasset 1951). Working in the areas of history and construction technology, the spirit of these statement guided my research: developing a research method for buildings not listed (yet) as monuments but needed to be analysed before the next approach. When studying buildings it is essential to consider not only the art history, social and urban planning factors, but especially the construction engineering aspects. In this way, a deeper understanding of the underlying design and building methods used in our built environment can be developed. There have been many historical and architectural studies of buildings. The period since the Second World War has received particular interest. Unfortunately, most of these studies do not address the technical aspects of the construction of these buildings. However, these issues were covered by publications at the time these buildings were constructed. Technology provided me with the inspiration to develop a more comprehensive research method to assess buildings: Analysing Buildings from Context to Detail in time: ABCD research method. Technology, at academic level, should be considered in the analysis of a building. Here we are concerned with construction engineering, the study of the requirements associated with constructing buildings. The Analysing Building Construction in time research matrix (ABC matrix) can be used in practice. It incorporates the study outcomes which relate to the building itself. Contextual aspects as well as building aspects are included. They can be analysed at the three time levels to draw conclusions which are relevant to the future existence of the building. The case study of the Friesland Provincial Library in Leeuwarden will be worked out in the conference paper.

Full textAbstract:
Improving the energy efficiency of existing buildings by implementing building automation control strategies (BACS) besides building envelope and energy system retrofitting has been recommended by the Energy Performance of Buildings Directive (EPBD) 2018. This paper investigated this recommendation by conducting a simulation-based optimization to explore cost-effective retrofitting combinations of building envelope, energy systems and BACS measures in-line with automation standard EN 15232. Two cases (i.e., a typical single-family house and apartment block) were modeled and simulated using IDA Indoor Climate and Energy (IDA-ICE). The built-in optimization tool, GenOpt, was used to minimize energy consumption as the single objective function. The associated difference in life cycle cost, compared to the reference design, was calculated for each optimization iteration. Thermal comfort of the optimized solutions was assessed to verify the thermal comfort acceptability. Installing an air source heat pump had a greater energy-saving potential than reducing heat losses through the building envelope. Implementing BACS achieved cost-effective energy savings up to 24%. Energy savings up to 57% were estimated when BACS was combined with the other retrofitting measures. Particularly for compact buildings, where the potential of reducing heat losses through the envelope is limited, the impact of BACS increased. BACS also improved the thermal comfort.

Full textAbstract:
This work proposes an innovative integrated retrofitting system aiming to improve both the seismic and energy performance of existing reinforced concrete and masonry buildings. The system is based on engineered insulating concrete form panels, installed on the outside of existing buildings as a shell exoskeleton. A key major advantage of the proposed system is that it addresses the contemporary improvement of seismic and energy performances of existing buildings in a single installation stage, operating exclusively from outside of the building. The insulating formworks are ad hoc prefabricated in a factory on the base of the specific geometry of the existing buildings so as to greatly maximize the ratio between overall retrofitting benefits and costs and at the same time to simplify the installation procedures. The objectives of the presented research are, on one hand, to highlight the major structural issues that the system aims to address, and on the other hand to illustrate the main characteristics and combined benefits of the proposed retrofitting system. From a structural point of view, the proposed system is conceived to behave as a non-dissipative structure with regard to seismic actions, and the lateral strength and stiffness of the structural elements are designed accordingly. An analytical design approach is proposed and validated using the available data from an experimental test performed on a full-scale simple building. Moreover, numerical modeling strategies for the proposed system are illustrated for two complex case study buildings. The results of the analyses show a considerable increase in lateral stiffness of the retrofitted buildings that, considering the non-dissipative behavior of the elements, leads to a relevant reduction of seismic deformation demand on existing structural elements.
