Full textAbstract:
t has been argued that green buildings have a better indoor environmental quality than conventional buildings and that this translates into a more satisfying workplace for the building's occupants and, inturn, a more productive workforce. Assessing a building's cost effectiveness means taking into account all the costs that will be incurred during its life cycle not just development costs. People found no evidence to believe that green buildings are more comfortable than conventional building. In fact, the only difference between the buildings was that occupants of the green building were more likely to perceive their work environment as warm, and occupants who felt warm were more likely to describe their work environment as poor.

Purpose The aim of this paper is to demonstrate the use of historical building performance data to identify potential issues with the build quality and operation of a building, as a means of narrowing the scope of in-depth further review. Design/methodology/approach The response of a room to the difference between internal and external temperatures is used to demonstrate patterns in thermal response across monitored rooms in a single building, to clearly show where rooms are under-performing in terms of their ability to retain heat during unconditioned hours. This procedure is applied to three buildings of different types, identifying the scope and limitation of this method and indicating areas of building performance deficiency. Findings The response of a single space to changing internal and external temperatures can be used to determine whether it responds differently to other monitored buildings. Spaces where thermal bridging and changes in use from design were encountered exhibit noticeably different responses. Research limitations/implications Application of this methodology is limited to buildings where temperature monitoring is undertaken both internally for a variety of spaces, and externally, and where knowledge of the uses of monitored spaces is available. Naturally ventilated buildings would be more suitable for analysis using this method. Originality/value This paper contributes to the understanding of building energy performance from a data-driven perspective, to the knowledge on the disparity between building design intent and reality, and to the use of basic commonly recorded performance metrics for analysis of potentially detrimental building performance issues.

AbstractThe acquisition of data regarding the performance of buildings and the use of metrics to understand their performance level are critical for efficient building management. Performance indicators are key elements in this process. They shall be clearly defined and provide the means for easily measuring building performance. These performance indicators should cover all aspects of a building's life cycle including safety, operability and sustainability. To facilitate such a process, it is preferable to group the performance indicators into categories, namely the key performance indicators. In this paper, the key performance indicators for buildings are determined by compiling the identified critical ones in the literature. A case study of an R/C building in Greece is used to quantify the presented metrics focusing mainly on safety. The reliability index indicator is calculated based on the simulation and analysis of a building subsystem. Other key performance indicators relevant to building maintenance are considered on scenario basis. The study has been conducted as part of the IABSE Task Group 5.2. – “Key Performance Indicators: Definition” and provides valuable insight into using quantified metrics for decision‐making in building management.

Full textAbstract:
Indoor environmental quality (IEQ) is important to the health, comfort, and well-being of building occupants. Unsatisfactory IEQ is associated with a number of phenomena, most notably, sick building syndrome (SBS), building-related illnesses (BRIs), and multiple chemical sensitivity (MCS), which have major negative effects on productivity. However, green building investors (owners) are not only concerned about reducing the negative impact of their buildings on the environment, but also about the potentially negative impact green buildings can have on their employees' productivity. This research sets out to address, through a questionnaire survey in South Africa, what constitutes the determinants of green building occupants' satisfaction with the IEQ elements of a green building and the health implications of a building's IEQ on the building occupants. Data analysis (involving a one-sample t-test) reveals some interesting findings in regard to what constitutes the determinants of green building occupants' satisfaction with the IEQ elements and the health implications of the IEQ elements of a five-star green rated building in South Africa. Findings from the survey revealed that the occupants of the building were not satisfied with the green building's IEQ, most especially the ineffectiveness of blocking natural and artificial lighting. Also, it was revealed that the IEQ with particular reference to the noise level and ventilation of the space has some serious health implications for the building occupants. The occupants' evaluation revealed that the major health issues from which they suffer include fatigue, headache, common cold, coughing, and influenza, and these affect their productivity and performance. Since building occupants are a rich source of information about IEQ assessment and its effect on productivity, the study can be used to assess the performance of green buildings, identify areas needing improvement, and provide useful feedback to designers and operators about specific aspects of green building design features and operating strategies that need improvement. This study adds to the body of knowledge on green buildings' IEQ performance.

Performance based design explicitly evaluate how a building is likely to perform given the potential hazard it is likely to experience , considering uncertainties inherent in the quantification of potential hazard and uncertainties in assessment of the actual building response. It is an iterative process that begins with selection of performance objective, followed by the development of a preliminary design assessment as to whether or not the design meets the performance objective and finally redesign and reassessment if required until the desired performance level is achieved. In present study two R.C. buildings, one rectangular and one square in plan are analyzed using pushover analysis and redesigning by changing the reinforcement in columns.

Full textAbstract:
Purpose: This study is a development of previous studies that focused on testing building performance from the aspect of building comfort. A house is a place to live that is used daily that must meet the needs of the occupants' thermal comfort which is greatly influenced by environmental and building conditions, such as natural lighting, air flow, and thermal performance as well as the conditions of the building's orientation layout and space openings. To determine the thermal performance of a building, it is necessary to conduct several analyses of several parameters of air temperature, air circulation and thermal conditions that occur in buildings in several conditions of building layout or orientation and openings made. Theoretical reference: Adaptive buildings are buildings that have adaptation to external environmental conditions, occupant needs and building operational conditions with the aim of increasing energy efficiency, comfort and sustainability. These adaptive buildings are able to provide a more comfortable environment, flexible and efficient space by maximizing natural ventilation and using building materials that function as insulation against temperature and solar radiation. Method: To determine the thermal comfort conditions of the building, it is necessary to conduct several tests on several parameters, such as natural lighting, air flow, and thermal performance using several analyzes such as solar analysis, air movement analysis and thermal analysis of the planned building prototype with several alternative building orientations. To test the thermal performance of the building, solar analysis and thermal analysis are carried out using Revit-based computational fluid dynamics (CFD). Results and Conclusions: The results of the study showed that the influence of building orientation and opening placement patterns will produce several different thermal performances. And the optimal results obtained from this adaptive strategy were that the optimal heat generated caused heat generation in the envelope of 0.76 kW/m2, meaning that by considering the heat transfer value of the building envelope not exceeding 35 W/m2 (SNI 6389:2020), a wall envelope made of 10 cm thick calciboard with air holes was used to withstand the rate of heat flow into the room. Research implications: As part of the adaptive building context that supports the field of knowledge and practice in the fields of architecture, engineering and the environment, it has positive implications related to the flexibility of spatial arrangement to adjust to the needs of occupants' space, the use of more efficient and environmentally friendly building technology and materials according to the needs of adaptive buildings, and the adjustment of natural ventilation strategies according to local climate potential. Originality/value: The components that distinguish this research from previous research can be seen from the various approaches and innovations carried out by the author, namely: Adaptive Design Method: developing the functionality of spatial arrangements in post-disaster residential buildings that apply the principles of spatial efficiency and arrangement to improve more dynamic relationships between spaces and their relationships with the surrounding environment. Use of New and Data-based Technology: applying new technology in ways to monitor and control the quality of space with the surrounding environment that affects it in real-time. Using technology applications for data analysis, modeling and predicting the performance of post-disaster residential buildings according to environmental and building parameters that affect them, and using big data analysis to understand the thermal behavior of buildings to optimize building design and operations.

Mitigation measures against railway vibration in buildings include elastomeric mounts or springs inserted between building foundations and upper-structures. This paper aims at evaluating on site the field performance of such building base isolation. Two performance indicators are defined and used, both expressed as insertion gain: a Power Flow insertion Gain (PFIG) based on the power transmitted to the building upper-structure, and a Building Insertion Gain Indicator (BIGI) based on the building floor velocities. The paper shows that both indicators can be used to evaluate the field performance of base-isolated buildings: the PFIG can be indirectly obtained from local measurements of the isolator transmissibility and some knowledge of the mobility magnitudes of the building structures in contact and the BIGI indirectly obtained from measurements of the treated building transmissibility (as defined in ISO/TS 14837-31) and some knowledge of the transmissibility of similar but untreated buildings. The methods are successfully validated using a numerical model of a 2D ground-building configuration easy to calculate and assumed realistic enough. The paper ends with a discussion on the practicality of obtaining these performances on- site in real buildings.

 Energy demand in buildings can reduce by improving energy efficiency. MS1525 has recommended that energy efficiency for Non-Residential Buildings in Malaysia to be not more than 135kWh/m²/year. A school building is a non-residential building and has major social responsibilities. Based on the theory of building energy-efficiency, energy efficiency can be achieved through three main factors: a) design of buildings; b) design of services; and c) user behavior. This study aims to investigate the user perceptions in High-Performance Schools.

The earthquake accompanied by a tsunami that occurred in Palu City in 2018 resulted in damage, especially reinforced concrete buildings, one of which was the FISIP Dean Building, Tadulako University. This study aims to evaluate the seismic performance of the building using SeismoStruct software. This software is able to predict the behaviour of large displacements of space frames under static or dynamic loading by considering geometric nonlinearity and material inelasticity. Building modelling is made based on Detail Engineering Design drawings. The results of the analysis in the form of a capacity curve show that the building's performance is at the life safety level, which means that structural components are damaged so that the building's strength is reduced. There are two types of building collapse mechanisms that occur, namely yielding in the reinforcement (yield) and collapse in the concrete cover (crush-unconfined). Collapse occurred in the column where it should have occurred in the beam.

Of the total 5.9 million existing buildings, the Office occupies the 2nd position of the most types of buildings with 16% of the Total Total. The least used aspect of BIM (Building Information Modeling) is the ability to obtain building energy models using the 6D BIM methodology. This digital information model is to simulate building energy and improve building energy systems. In this way, 6D BIM simulation allows us to make building design and operational decisions. In the case of increased energy, which leads to greater quality and comfort in the sustainable use of buildings. This issue has a special relationship in public buildings. Where energy efficiency and comfort are two fundamental criteria that are highly valued by society. Once the building's energy model is prepared, it will study and identify possible ones to improve energy efficiency, as well as analyze the incorporation of other, more efficient forms of renewable energy such as the use of natural light.

The high-performance insulations and energy-efficient HVAC have been widely employed as energy-efficient retrofitting for building renovation. Building performance simulation (BPS) based on physical models is a popular method to estimate expected energy savings for building retrofitting. However, many buildings, especially the older building constructed several decades ago, do not have full access to complete information for a BPS method. To address this challenge, this paper proposes a data-driven approach to support the decision-making of building retrofitting under incomplete information. The data-driven approach is constructed by integrating backpropagation neural networks (BRBNN), fuzzy C-means clustering (FCM), principal component analysis (PCA), and trimmed scores regression (TSR). It is motivated by the available big data sources from real-life building performance datasets to directly model the retrofitting performances without generally missing information, and simultaneously impute the case-specific incomplete information. This empirical study is conducted on real-life buildings in Sweden. The result indicates that the approach can model the performance ranges of energy-efficient retrofitting for family houses with more than 90% confidence. The developed approach provides a tool to predict the performance of individual buildings from different retrofitting measures, enabling supportive decision-making for building owners with inaccessible complete building information, to compare alternative retrofitting measures.

The building sector accounts for 19% of Australia's energy consumption and around 23% of the greenhouse gas emissions. In 2005, commercial buildings in Australia were responsible for 10% or 26 megatonnes (Mt) of the nation's greenhouse gas emissions. They are two effective ways to reduce the building sector's emissions, namely constructing new energy efficient buildings or retrofitting existing buildings. Due to the life expectancy of existing building stock the greatest reduction in emissions before 2030 could be achieved through retrofits. Building performance assessment and evaluation uses predictive modelling method to investigate and evaluate building performance in energy demands, thermal occupant comfort, indoor air quality, building retrofit options and many other related environmental and wellbeing aspects. This paper discussed the use of building performance simulation software to investigate the impacts of various retrofit options have onto energy performance of existing commercial buildings with heritage values in Australia. The research explores the use of thermal and airflow modelling in assisting understanding of building energy performance with various retrofit options applied to existing commercial buildings. The finding highlights the capabilities of building performance simulation software in decision making for building performance investigations.

The global warming issue has become a concern for environmentalists activists, including many governments. This concern is due to the increasing attention to reducing the use of fossil energy because fossil energy has significantly exacerbated global warming. To minimize the use of fossil energy, especially the housing sector that is one of the extensive energy users. Building performance's analysis is done by creating changes to the case study's building envelope material. Case study buildings were simulated in energy analysis software. Preliminary analysis shows how the performance of the case study building is still far from the standard of thermal comfort. Air conditioning (AC) usage in the room will give comfort in terms of temperature. But, even though with the AC, the humidity level of the room was still high. Two building models are then created in the software to see the performance of the building by making changes to the building envelope material. With the settings on air-conditioning (AC) and environmental conditions in both models, the results indicate differences in the building performance of the two buildings. The results show that the building with insulation are using less energy and can provide optimal comfort for building users. Comfort is not only in terms of the building's temperature but including building relative humidity. In buildings with insulation, the temperature and humidity of the building are relatively stable throughout the year.

Abstract Post-occupancy evaluation (POE) is a method for measuring building performance in terms of meeting design intent, and identifying any gaps between actual and modelled performances in the of aspects indoor environmental quality (IEQ), occupant satisfaction, energy consumption, etc. In this paper, a structured POE assessment was conducted using the Building Use Survey (BUS) methodology in two higher educational buildings in the United Kingdom. This study aims to help close the building performance gap, optimize building operation systems, and improve occupants’ satisfaction levels. In this research, the questionnaire survey investigated the influences of environmental factors on user satisfaction from the main aspects of building overall design, thermal comfort, perceived control, indoor environment quality for noise, lighting, ventilation, and other non-environmental factors, such as the background information about age, gender, time in buildings, workgroup size, and so on. The results indicate that the occupant satisfaction with the main aspects of building overall design, indoor environment quality, and thermal comfort in summer and winter in both buildings is lower than the benchmark data. The feedback of this POE assessment has been reported to the building management team to allow managers to develop high-performance building operation guidelines to narrow down the performance gap and improve user satisfaction, comfort, and productivity.

Building performance evaluations (BPEs) were carried out for nine Canadian green buildings using a standardised assessment framework. The aim was to explore and measure the discrepancies between the operational performance of the buildings and their predicted performance, as well as to identify lessons for their owners, design teams and the construction industry. The objective of this paper is not to report individual buildings in detail (we refer the reader to the individual building reports) but to report on some general lessons that came from doing this study. Overall these buildings performed well compared to benchmarks. However, the findings suggest that occupancy is not well understood and often incorrectly predicted during design, and that this affects various aspects of performance, including energy and water use. Also energy and water use modelling is often undertaken principally for building code/green rating compliance purposes and does not necessarily represent an accurate prediction of likely operational use. Combined with variations in occupancy this can lead to considerable discrepancies in performance from the modelled values. This may be understood by experts but is often misleading to building owners and others. Water use is often not well predicted and also not carefully managed in buildings and there is a lack of understanding of what constitutes good water performance. Overall, it is important to recognise that each building has its own individual “story” that provides necessary context for effective management and improvement of the building during its ongoing life. It is proposed that a BPE process allows that context to be better understood, and enables more effective decision making about building management, improvements, occupant satisfaction, energy use, etc.

Full textAbstract:
Seismic behaviors of a five-story welded steel moment-frame (WSMF) office building in Kobe, Japan, and a six-story WSMF office building in Northridge, California, are compared. Both experienced earthquake damage (1995 Kobe and 1994 Northridge earthquakes, respectively). Computer models of the buildings are formulated, having the ability to simulate damage in terms of fractured moment connections. Analyses are conducted to assess building response during the earthquakes. The calibrated models are then analyzed using a suite of earthquake records to compare building performance under consistent demands. The Kobe building is found to be more rugged than the Northridge building. Analysis suggests it would experience much less damage than the Northridge building from shaking equivalent to 2,500-year earthquake for a generic Los Angeles site. Superior performance of the Kobe building is attributed to its relatively greater stiffness and strength. The results provide insight into the difference in seismic fragility expected for this class of mid-rise WSMF buildings in Japan and the United States.

Several studies have analyzed the integration of energy-saving strategies in buildings to mitigate their environmental impact. These studies focused mainly on a disaggregated analysis of such strategies and their effects on the building's energy consumption and thermal behavior, using energy engine simulation software (EnergyPlus, TRNSYS, and DOE2) or graphical interface software (DesignBuilder, eQuest, and ESP-r). However, buildings are complex systems whose energy behavior depends on the interaction of passive (e.g., location and construction materials) and dynamic (e.g., occupation) components. Therefore, this study proposes a composite indicator Building’s Energy Performance (BEP) as an alternative to deal with this complex and multidimensional phenomenon in a simplified way. This indicator considers energy efficiency and thermal comfort. The Electrical Engineering Building (EEB) of the Universidad Industrial de Santander was selected to verify the performance of the BEP indicator. In addition, a sensitivity analysis was performed for different mathematical aggregation methods and weighting values to test their suitability to reproduce the building behavior. Different simulation scenarios modeled with DesignBuilder software were proposed, in which the energy-saving strategies integrated with the building was individually analyzed. The results confirmed that the integration of the building's energy-saving strategies improved the BEP indicator by approximately 16%. It has also been possible to verify that the BEP indicator adequately reproduces the building’s energy behavior while guaranteeing comfort conditions. Finally, the Building Energy Performance indicator is expected to contribute to the integration of sustainability criteria in the design and remodeling stages of buildings.

Full textAbstract:
A courtyard masonry building is a series of masonry buildings built in-close forming a square or rectangular space at middle of buildings. Courtyard is the central part of the buildings. It is also the flourishing place for social and cultural activities and the safer place for rescue and shelter during earthquake. In different places of Kathmandu valley courtyard typed housing is found which are historically important and preserved as a world heritage sites. These buildings are susceptible to damage due to interaction of adjacent building and due to the arrangement of buildings in courtyard pattern. This study evaluates the performance of the buildings in court-yard form during seismic loading. Typical arrangement and height of the buildings in conglomeration which is usually found in different parts of Bhaktapur district are selected. From the simulation and analysis, the buildings in conglomeration are more flexible and resist more seismic force, while the buildings in corner are more vulnerable, and hence weak for the same seismic loading.

Full textAbstract:
Structural engineers typically improve the seismic performance of deficient structures by adding strengthening elements to the structural system, which also add stiffness to the structure. However, as performance based design becomes more common practice, the focus is on the total performance of not only the structural system but the building components and contents. A stiffer and stronger building will generally be subjected to lower drifts but higher floor accelerations than a weaker and/or more flexible building. Reduced drift related damage may be accompanied by increased damage to components and contents which are sensitive to accelerations.
 This paper examines two common forms of hardware used to strengthen existing buildings, buckling restrained braces (BRB) and viscous damping devices (VDD). Both types of device augment the existing structural system, rather than replace it. A series of nonlinear analyses is used to quantify the performance of two prototype frame buildings strengthened with each type of device. It is shown that equivalent structural performance, in terms of overall deformations, can be achieved with both types of device, and generally for lower cost by BRBs if only moderate levels of drift reduction are required. However, when the total building performance is examined the VDDs provide additional benefits in the form of reduced floor accelerations. The benefits of this may besufficient to warrant the higher cost solution.

Full textAbstract:
Existing buildings are likely to consume more energy and emit more greenhouse gases than new buildings because of inevitable deteriorations in physical performance. Accordingly, retrofitting of existing buildings is considered essential to reduce energy consumption and greenhouse gas emissions from the building sector. However, assessing the energy performance of existing buildings accurately has limitations because building materials undergo physical deterioration and the actual operational conditions differ from as-built documentation. There is also a difference in the level of data acquisition required for building energy performance assessment depending on the conditions of the building. The aim of this paper is to present types of methods for energy performance assessment of existing buildings considering this data acquisition level. We analyzed various assessment methods, which were classified into three prototypes of methods according to the required level of data acquisition. Type 1 assessed the target building based on literature sources. Type 2 conducted on-site audit and assessed the target building based on additional collected data. Type 3 assessed the target building by further estimating the building properties through analysis of the measured energy data. The applicability of the proposed methods were demonstrated using case studies of three buildings located in Seoul, South Korea.

Building Integrated Photovoltaic (BIPV) systems can be defined as PV modules, which can be integrated in building's envelope by replacing conventional building materials such as windows, tiles etc. and have an impact on the functionality of the buildings. Considering the huge share (40%) of buildings in total energy consumption and nearly zero-energy building target of the European Union (EU), BIPV systems present a sustainable solution and have gained increased interest in last years. In this study, the performance of a BIPV system, which was installed on Feb. 8, 2016 on the façade of a campus building at Yasar University, İzmir, Turkey within the framework a EU/FP7 project and has a capacity of 7.44 kWp, is evaluated for a three-year period using first and second laws of thermodynamics. Within this context, real (experimental) monthly and yearly electricity productions are determined and compared with the results obtained from the simulations. Energy and exergy efficiencies and performance ratios of the system are also calculated based on the cell and total areas.

Abstract Energy efficient design is a high priority in the national energy strategy of European countries considering the latest requirements of the European Directive on the Energy Performance of Buildings. The residential sector is responsible for a significant quantity of energy consumptions from the total amount of consumptions on a worldwide level. In residential building most of the energy consumptions are given mainly by heating, domestic hot water and lighting. Retrofitting the existing building stock offers great opportunities for reducing global energy consumptions and greenhouse gas emissions. The first part of the paper will address the need of thermal and energy retrofit of existing buildings. The second part will provide an overview on how various variables can influence the energy performance of a building that is placed in all four climatic zones from Romania. The paper is useful for specialist and designers from the construction field in understanding that buildings behave differently from the energy point of view in different climatic regions, even if the building characteristic remain the same.

The case study presents, green building's positive net present value (NPV) investment in real terms and potentially enhanced stock market returns at the firm level compared to competitors.Design/methodology/approachThe case study examines secondary data on a green building certification and longitudinal operation costs to estimate green building investments' financial benefits. The case study also compares the stock market performance of green building portfolio company with non-green building competitors of similar size and industry.FindingsThe case study finds out that the real return rate on green building investment is higher than the weighted average cost of capital (WACC) of the company with an inflation-adjusted payback period of fewer than ten years. Findings compare favourably to the extant literature which was mostly in developed economies. The paper further highlights that stock market performance for a green building focused company shows improved returns to shareholders relative to non-green competitors.Research limitations/implicationsThe results are specific to the time and building researched; green buildings costs have reduced over time, and a new study may show improved case study findings. The case study results on stock market performance are indicative and may need further research for evaluation.Practical implicationsThe case study presents a model for critical appraisal of green buildings investment. The paper further indicates that green building investment may lead to operational savings and superior stock performance compared to competitors.Originality/valueThe paper presents a green building investment appraisal model which might be useful for the industry and academia. Developing countries have limited literature on green buildings' financial benefits; this case study quantifies the financial benefits and compares them with the available literature related to developed economies’ green buildings.

Full textAbstract:
Hospitals are controlled yet complex ecosystems which provide a therapeutic environment that promotes healing, wellbeing and work efficiency for patients and staff. As these buildings accommodate the sick and vulnerable, occupant wellbeing and good indoor environmental quality (IEQ) that deals with indoor air quality (IAQ), thermal comfort, lighting and acoustics are important objectives. As the specialist nature of hospital function demands highly controlled indoor environments, this makes them energy intensive buildings due to the complex and varying specifications for their functions and operations. This paper reports on a holistic building performance evaluation covering aspects of indoor air quality, thermal comfort, lighting, acoustics, and energy use. It assesses the performance issues and inter-relationships between IEQ and energy in a new building on a hospital campus in the city of Bristol, United Kingdom. The empirical evidence collated from this case study and the feedback received from the hospital staff help identify the endemic issues and constraints related to hospital buildings, such as the need for robust ventilation strategies in hospitals in urban areas that mitigate the effect of indoor and outdoor air pollution and ensuring the use of planned new low-carbon technologies. Whilst the existing guidelines for building design provide useful instructions for the protection of hospital buildings against ingress of particulate matter from outdoors, more advanced filtration strategies may be required to enact chemical reactions required to control the concentration levels of pollutants such as nitrogen dioxide and benzene. Further lessons for improved performance in operation and maintenance of hospitals are highlighted. These include ensuring that the increasingly available metering and monitoring data in new buildings, through building management systems, is used for efficient and optimal building operations for better IEQ and energy management. Overall, the study highlights the need for an integrated and holistic approach to building performance to ensure that healthy environments are provided while energy efficiency targets are met.

Full textAbstract:
Internationally, buildings are a major contributor to carbon emissions. Despite significant advances in the technology and construction of energy-efficient buildings, in many cases a performance gap between designed and actual performance exists. While much research has investigated the drivers of the building energy performance gap – both static and transient– there has been considerably less research into the total performance gap, defined here as performance gaps in building energy use, occupant satisfaction and Indoor Environmental Quality parameters such as thermal comfort and air quality which may impact on occupant health and wellbeing. This paper presents a meta-analysis of building performance data from buildings in the UK and China – selected due to their contrasting development environments – which illustrate the presence of and complexities of evaluating total performance gaps in both countries. The data demonstrate the need for (1) high end-use, spatial granularity and temporal resolution data for both energy and Indoor Environmental Quality, and (2) developing methodologies that allow meaningful comparisons between buildings internationally to facilitate learning from successful building design, construction methodologies and policy environments internationally. Using performance data from a UK building, a potential forward path is illustrated with the objective of developing a framework to evaluate total building performance. Practical application: While much research has examined building energy performance gaps, Indoor Environmental Quality and occupant satisfaction gaps are rarely included despite their relationship to energy. We use a meta-analysis of energy, indoor environmental quality, and occupant satisfaction data from buildings in the UK and China to illustrating the presence of and complexities of evaluating total performance gaps for buildings in the two countries, and the need for high resolution dynamic buildings data and novel methodologies for comparison between buildings across different contexts. Illustrative case studies are used to demonstrate potential future directions for evaluating ‘total’ building performance.

Full textAbstract:
Seismic isolation systems have been recognized for their effectiveness in protecting building and their contents. Despite costly technology, seismic isolation has been used in several countries, including Japan. Base-isolated building response could be substantially reduced, which is very favorable compared to conventional fixed-base buildings. Several studies have focused on base-isolated building response and the effects of isolation properties, for example, but none has talked about performance in ways that nonengineers such as building owners could understand. The slight damage from an earthquake may protect a building’s structural integrity, but it may also damage nonstructural components and disrupt ongoing building functionalityCF. The PEER methodology framework used to considerCFdamage to nonstructural components uses a nonstructural component fragility curve, taking into account building location, and produces results in the form of a return period, in years, indicating how long the building may be expected to exceed that specified damage state. Several building structures are investigated and discussed.

Purpose The complex nature of multi-ownership, multi-storey buildings requires the services of property management companies (PMCs). Naturally, homeowners favor PMCs with good performance. Yet, their performances vary. The purpose of this paper is to measure the performance of PMCs in managing high-rise flats using the logic model as the contextual framework with its indicators adapted from the building quality index (BQI) scheme. Design/methodology/approach For this pilot study, the research was based on visual inspection and interviews with building management staff for the information concerning the output and outcome indicators. The authors also tested the relationship between outcomes and outputs and other factors that affect the performance of PMCs. Findings Based on our pilot study of 41 high-rise residential buildings, the performance outcomes of the PMCs varied considerably. The same PMC was likely to yield different performance outcomes due to unique building characteristics. The outputs, building ages and rehabilitation statuses of the buildings were the contributing factors to the PMCs’ performance outcomes. Practical implications The performance outcomes of the logic model can help homeowners and PMCs understand current PMC performance, which can help trigger the development of a strategy to enhance the health and safety of residential buildings in the future. Originality/value Unlike traditional performance measurements that use financial figures or balanced scorecards to measure organizational performance, the authors used the logic model performance measurement system because the performance outcomes of the PMCs were explicitly reflected in the physical building conditions. This framework was relatively straightforward and could be applied to cities dominated by multi-ownership, multi-storey apartments.

The Buildings on the hills differs from other buildings constructed in plain terrain. Each floor of building steps back towards the hill slope and at the same time buildings may have designed with setbacks configuration also. Buildings constructed in hilly areas are more vulnerable to seismic environment. This study is on generating a 3D analytical model of multi-storey buildings analyzed using structural analysis tool ‘ETABS” to study the effect of varying height of columns due to sloping ground and the effect of bracing at different positions in a different configuration of the building during an earthquake. Seismic analysis has been done using the response spectrum method. The performance of the buildings on the sloping ground is highly vulnerable to earthquake on each storey level. Buildings resting on sloping ground with step back configuration are compared to buildings resting on the plain ground with same type load applied to each of the structure. From this study entire modelling the behaviour of normal ten storey building, step back, set-step back ten storey building is studied, it is found that the displacement and base shear value shows the performance of step back building and set-step back building. This is research also focus on effective placement of bracing with different types and in different positions. The displacement values show better performance by providing X bracing in the lateral direction.

Full textAbstract:
In order to achieve carbon neutrality in the building field as expected by the Energy Performance of Buildings Directive, it is important to not only be able to calculate energy performance during design but also to be able to measure the actual energy performance of buildings during occupancy. However, there is currently no approved methodology for assessing the energy performance of the building envelope of an occupied building independently of its occupants, its systems and the climate. We applied a mathematical method to determine the heat loss coefficient (HLC) of the building envelope, from data collected in occupied buildings. The paper describes the in-situ measurement protocol and the mathematical models that contributes to address this challenge. Our methodology is demonstrated on a new semi-detached house, more insulated than the regulatory level, located in Brussels from a full year of monitoring data. For this case study, the results are promising. Indeed, some mathematical models show results of the same range value for the occupied insitu HLC and the reference HLC, obtained from in-situ measurements but without occupancy. However, more case studies should be evaluated, in order to validate the methodology.

Climate change and environmental degradation have become pressing global issues, and building construction will inevitably affect the environment. Based on data from the World Building Council, buildings globally contribute to 40% of energy emissions and 50% of CO2. The rapid growth of urbanization and increased demand for residential and commercial space demand more environmentally friendly solutions. Green building performance assessment has become an increasingly important topic in the construction industry. Green building is an innovative approach to designing and operating environmentally friendly buildings. Green building performance assessment in campus buildings is an important process in an effort to improve the sustainability of the campus environment. The results of the research analysis of green buildings in Building F Faculty of Engineering obtained cumulative results of light intensity 1080.8 lux for the minimum value, 1143.7 lux for the maximum value, and 1140.5 lux for the average value. Cumulative temperature obtained a minimum value of 28.6 ̊C, a maximum value of 28.7 ̊C, and an average value of 28.6 ̊C. Cumulative humidity obtained a minimum value of 60.2 RH, an average value of 60.4 RH, and a maximum value of 60.7 RH. The result of the WWR value on the envelope is 31.5% ≥ 30%. In the checklist of the 2021 PUPR Regulation No. 21, 31 out of 83 points were obtained for green building research. This assessment aims to evaluate the extent to which campus buildings meet sustainability criteria, which include energy efficiency, water management, use of materials and resources, and indoor environmental quality.

Full textAbstract:
The environmental performance assessment of the building and construction sector has been in discussion due to the increasing demand of facilities and its impact on the environment. The life cycle studies carried out over the last decade have mostly used an approximate life span of a building without considering the building component replacement requirements and their service life. This limitation results in unreliable outcomes and a huge volume of materials going to landfill. This study was performed to develop a relationship between the service life of a building and building components, and their impact on environmental performance. Twelve building combinations were modelled by considering two types of roof frames, two types of wall and three types of footings. A reference building of a 50-year service life was used in comparisons. Firstly, the service life of the building and building components and the replacement intervals of building components during active service life were estimated. The environmental life cycle assessment (ELCA) was carried out for all the buildings and results are presented on a yearly basis in order to study the impact of service life. The region-specific impact categories of cumulative energy demand, greenhouse gas emissions, water consumption and land use are used to assess the environmental performance of buildings. The analysis shows that the environmental performance of buildings is affected by the service life of a building and the replacement intervals of building components.

Full textAbstract:
Engineers usually focus on the performance of structural members, whereas the occupants of a residential building are affected mostly by the performance of infill and partition walls in buildings after a moderate earthquake. This often creates controversy and discussion regarding the post-earthquake use of buildings. Seismic rehabilitation codes for existing buildings offer sophisticated measures in rating the seismic performances of structural components, whereas performance measures suggested for infill and other partition walls are crude by comparison. Furthermore, seismic design codes for new buildings totally disregard such disparity, since their force-based approaches are built on single-level performance targets specified implicitly for the entire building under a design level, that is, a rare earthquake. In this paper, performance levels of buildings after an earthquake of moderate intensity are discussed from the viewpoints of engineers and building occupants. Suggestions are made for achieving uniform performance in structures where the seismic forces are resisted by structural members as well as the infills and partition walls coupling with the structural system although the contribution of such walls to seismic resistance and their performance is not usually considered in design.

Building performance management requires massive data input; however, the relevant data are separated and heterogeneous; thus, it prevents a comprehensive building performance management. Building information modeling brings a new way to capture rich information of a building, and has great potential in data interoperability for building performance management. This article presents a scalable building information modeling–based cyber-physical platform for building performance monitoring to integrate heterogeneous data from different buildings. A smart sensor network based on Arduino and standard protocol is installed for data sensing and collection. A building information modeling–based sensing information model integrating heterogeneous data in a unified structure is proposed, and a scalable NoSQL database is established to store data in a cloud environment. A series of RESTful web services is developed to share data for building performance management applications. The proposed platform is developed taking the advantage of horizontal scalability of NoSQL database, and the data schema and services are generated automatically based on the unified data model. The platform has collected data from 77 buildings in China, and the results of a case study show the platform brings a new paradigm in collecting, storing, integrating, and sharing of sensor data and building information for building performance monitoring and analytics.

Full textAbstract:
The rising interest in low energy building has led to an inflation in related terminology: (nearly) zero energy buildings, or (n)ZEBs, passive houses, positive energy buildings and districts, off-grid buildings, energy autarkic buildings, etc. Each of these terms involves (sometimes subtle) differences in interpretations, system boundaries, included energy end uses, etc. This paper maps the differences and overlaps in applications of various cases of residential High Energy Performance Buildings (HEPBs), aiming to contribute in the development of a novel taxonomy to evaluate the extent to which a building can be considered energy or carbon neutral. Three dimensions are suggested for specification in novel taxonomy for HEPBs: (i) the spatial dimension (energy use, locally renewable energy production and sometimes energy storage), (ii) the time dimension (during which period is the building and its systems balanced, e.g. yearly or momentary) and (iii) the end-use dimension (these are the end-uses that are included or excluded for the calculation of the total energy needs of the buildings).

This article aims to describe the main manifestations found in the external area of the residential building. The case study was performed through visual inspections of the structures, identifying the causes and proposing a correction method for these anomalies. Based on the literature review in books, articles, norms and laws, we sought to understand the definitions related to the inspection and preventive maintenance and corrective to the performance of the building, presenting the main points of interest using as reference the ABNT NBR 5674: 2012 - “Maintenance of buildings” and ABNT NBR 15575: 2013 “Performance of Housing Buildings”. After all the on-site survey was carried out, the intervention strategies were presented, ensuring that the facilities receive the necessary maintenance according to the needs of each environment. Therefore, it is concluded that the lack of maintenance in the residential building has caused discomfort in the residents and the expected performance for the building. Therefore, it is very important to have proper planning and conducting the building inspection throughout the building's life, and should have specialized and qualified professionals to perform preventive and corrective maintenance, so it will be possible to rescue its performance, ensuring durability, comfort and real estate appreciation.
