Considering the magnitude of energy loss in building, development of energy saving methods appears to be essential. Daylight plays a significant role in designing energy efficient buildings and improving visual comfort for the occupants. Many daylight analysis methods have been developed in this area. Most of these methods focus on opening maximization. These methods unfortunately might reduce comfort since it causes direct solar glare. There is a need for a reliable lighting simulation model to control the lighting strategy in early stage design. This study proposes a strategy for visualizing daylight analysis of buildings by using Integrated Dynamic Model (IDM). IDM is a combination of design tools used during the conceptual phase for holistic classroom that considers the building’s energy usage, daylight distribution, and thermal indoor environment. The optimization focus is related maximize the performance of the building envelope design. The purpose of this paper are; firstly, providing a new strategy for visualizing the predicting daylight while respecting architectural integrity. The second purpose is to facilitate the designer for choosing window and envelope design alternatives during early stages. The third is to maximize the positive impacts of daylight. Lastly, hopefully IDM could present a simplified simulation and analyze method with the timely, accurate and efficient process.

Abstract Tall buildings with irregular forms are gaining popularity in creating the vertical city model, and they are designed and built today with the help of computational technologies. This paper aims to highlight the significant link between the architectural and structural conceptual design of tall buildings with irregular geometries by using performance-driven evaluation and parametric design approach at conceptual stage to develop a sustainable design. Initially the review of previous research shows how the form of tall building is be defined. Furthermore, the parametric design approach is investigated for generating alternative options to satisfy building aesthetic and structural performance criteria with the aid of aerodynamic optimization technicque to generate an optimum solution for decision-making at an early stage, as well as allowing modifications in the later stages of design, and making it possible to handle the design process in a repetitive manner. Finally, a framework is proposed where computational techniques are integrated and an effective collaboration between professional designers is achieved in order to produce an optimal complex-tall building conceptual design that is architecturally pleasing, structurally efficient, and environmentally sustainable.

Purpose Effective building maintenance management is vital for reducing the impact of building defects and costly building maintenance work. Such practice significantly contributes to the public sector in terms of cost reduction, improved effectiveness and efficiency in maintenance works, increasing safety and well-being of the occupants, expanding the life of building stocks and expanding the value of investment for the government building assets. The maintenance practice in Malaysia is still emerging in comparison to many developed nations. The purpose of this study is to determine the current scenario of the building maintenance approach at the design stage in public buildings in Malaysia. Design/methodology/approach An extensive questionnaire survey was held, involving 312 key players (38 per cent out of 820 predetermined participants) in Malaysia. Findings The analysis showed that building maintenance in public building in Malaysia still uses the reactive approach. Despite the Malaysian Government’s adoption of a proactive maintenance approach, unfortunately, there are some misunderstandings among the key players regarding the approach. The research results demonstrate that the key players had a lack of understanding on the concept of the proactive maintenance management approach and that they were either ignorant or had insufficient awareness of proactive maintenance approach. Originality/value The contribution of this study is useful for the government to adopt a more proactive building maintenance policy at the design stage, to give awareness on proactive building maintenance to the key players in their construction project and as a guide to the key players to adopt a maintenance plan at the design stage of work.

Today the construction of green buildings is in full swing, and the concept of green goes deeply into the hearts of the people. However, practitioners in the construction industry often place the emphasis of green building construction on the stage of design and construction. They hardly realize that green building's operation stage is the most important part in the whole life cycle of the building. To build real green building, it also needs sustainable development in the operation stage. The appearing of BIM (Building Information Model) technique effectively solved this problem. Using BIM technique in operation stage can effectively promote work efficiency of the operation organization, improve quality of service to customers, reduce the occurrence of emergencies in building's operation stage, improve safety performance, reduce resources waste and then construct real green buildings.

The development of basketball in Pontianak City is in line with the availability of basketball sports facilities owned. Existing facilities are still inadequate or do not meet standards. Based on this phenomenon, the goal to be achieved in designing the Pontianak Basketball Arena is to produce a type A basketball sports building design in Pontianak City. This design refers to the Instruction Manual for Technical Planning for Sports Buildings published by the Ministry of the Public Works (1994) and Minister of Youth and Sports of the Republic Indonesia Number 0445 of 2014 concerning Standards for Sports Infrastructure in the Form of Buildings and using the design method proposed by Jones (1992), where the method is divided into several stages, namely the idea stage, problem identification stage, data collection stage, data analysis stage, synthesis stage, and design stage. This design gave a building divided into 2 floors. The square shape of the building was chosen because it is considered to be the most suitable shape according to the land site and also be the most efficient shape according to the room organization. The facade of the building displays a shape inspired by the patterns found in basketball and the culture that exist in the city of Pontianak. The colors in the building are contrasted to create a prominent feel to make it more attractive and sporty. The space frame structure system applied to the roof of the building was chosen based on several considerations.

To manage the concerns regarding the energy performance gap in buildings, a structured and longitudinal performance assessment of buildings, covering design through to operation, is necessary. Modelling can form an integral part of this process by ensuring that a good practice design stage modelling is followed by an ongoing evaluation of operational stage performance using a robust calibration protocol. In this paper, we demonstrate, via a case study of an office building, how a good practice design stage model can be fine-tuned for operational stage using a new framework that helps validate the causes for deviations of actual performance from design intents. This paper maps the modelling based process of tracking building performance from design to operation, identifying the various types of performance gaps. Further, during the operational stage, the framework provides a systematic way to separate the effect of (i) operating conditions that are driven by the building’s actual function and occupancy as compared with the design assumptions, and (ii) the effect of potential technical issues that cause underperformance. As the identification of issues is based on energy modelling, the process requires use of advanced and well-documented simulation tools. The paper concludes with providing an outline of the software platform requirements needed to generate robust design models and their calibration for operational performance assessments. Practical application The paper’s findings are a useful guide for building industry professionals to manage the performance gap with appropriate accuracy through a robust methodology in an easy to use workflow. The methodological framework to analyse building energy performance in-use links best practice design stage modelling guidance with a robust operational stage investigation. It helps designers, contractors, building managers and other stakeholders with an understanding of procedures to follow to undertake an effective measurement and verification exercise.

Buildings are one of the largest energy consumers in the world, and have great energy saving potential. Thermal systems and lighting systems take most of the energy in a building. Comparing with the optimization solutions developed for a thermal system, the research of improving the lighting system is insufficient. This study aims to improve the lighting environment and reduce the energy by optimizing the building design, which has the largest potential for cutting energy economically compared with the other stages in the life cycle of a building. Although many approaches have been developed for building design optimization, there is still one big problem obstructing their successful practices, in that the designers who take the responsibility of making building designs are not experts in building physics, thus they are not capable of calculating the most appropriate parameters and operating the professional software to optimize their designs. Therefore, this study proposes a user-friendly method for designers to improve building designs. Firstly, Building Information Modeling (BIM) and particle swarm optimization algorithm are applied to build an intelligent optimal design search system. The optimized design from this system can largely use daylighting for internal illumination and save energy. Secondly, different types of lighting control systems are compared and the one which can save maximal energy is added to the selected optimal design. A case study demonstrates that optimized designs generated by the proposed design method can save large amounts of life cycle energy and costs, and is effective and efficient.

Improving the energy efficiency of existing and new buildings is an important step towards achieving more sustainable environments. There are various methods for grading buildings that are required according to regulations in different places for green building certification. However, in new buildings, these rating systems are usually implemented at late design stages due to their complexity and lack of integration in the architectural design process, thus limiting the available options for improving their performance. In this paper, the model ENERGYui used for design and rating buildings in Israel is presented. One of its main advantages is that it can be used at any design stage, including the early ones. It requires information that is available at each stage only, as the additional necessary information is supplemented by the model. In this way, architects can design buildings in a way where they are aware of each design decision and its impact on their energy performance, while testing different design directions. ENERGYui rates the energy performance of each basic unit, as well as the entire building. The use of the model is demonstrated in two different scenarios: an office building in which basic architectural features such as form and orientation are tested from the very beginning, and a residential building in which the intervention focuses on its envelope, highlighting the possibilities of improving their design during the whole design process.

Optimizing the building performance at the early design stage is justified as a promising approach to achieve many sustainable design goals in buildings; in particular, it opens a new era of attractive energy-efficient design for designers and architects to create new building constructions with high-energy efficiency and better overall performance. Accordingly, this study aims to provide a comprehensive review of performance optimization studies on heating, cooling, and lighting energy systems of buildings during the design stages, conducting a systematical review covering various aspects ranging from the building type, optimization inputs, the approach used, and the main conclusion. Furthermore, the benefits and limitations of early optimizations in the energy-efficient design performance of buildings and future research directions are identified and discussed. The review results show that previous research efforts of optimizing energy-efficient design performance in buildings have addressed a wide variety of early stage design optimization issues, including orientation and multi-objective building function-related conflicts, such as cooling and lighting. However, significant research issues related to investigations of design envelope materials, proper energy-efficient design form, and other passive parameters, such as solar photovoltaic systems, are still lacking. Therefore, future research should be directed towards improving existing optimization approach frameworks in the context of appropriate energy-efficient design features; integrating sensitivity and uncertainty analyses in the performance optimization framework of buildings to provide a more balanced assessment of influential design envelope properties and extending optimal design envelope investigations of buildings to include other passive parameters and lifecycle assessment under long-term weather conditions.

Renewable energy systems (RES) in buildings should be designed carefully, not only because of the need for an optimal design, but also to comply with related laws. Therefore, the design of RES in the buildings requires close collaboration between architects and engineers from the beginning of the design process. To support such collaboration, this study proposes a simplified design method for RES in buildings during the early design stage. By using the proposed design method, design alternatives that meet the required energy standards as suggested by law are first generated. Further designs are made to evaluate the performance and cost of the design alternatives and to find the optimal types of RES for the building. The study also uses a case study to verify the applicability of the design method to the early design stage. Although the performance and cost of the different design alternatives are similar, the implementation of each type of RES in each design alternative is different. Nonetheless, by analyzing performance patterns and the cost ratio of each type of RES in each design alternative, the study allows the most suitable type of RES to be chosen for the building.

Building performance evaluation is generally carried out through a non-automated process, where computational models are iteratively built and simulated, and their energy demand is calculated. This study presents a computational tool that automates the generation of optimal building designs in respect of their Life Cycle Carbon Footprint (LCCF) and Life Cycle Costs (LCC). This is achieved by an integration of three computational concepts: (a) A designated space-allocation generative-design application, (b) Using building geometry as a parameter in NSGA-II optimization and (c) Life Cycle performance (embodied carbon and operational carbon, through the use of thermal simulations for LCCF and LCC calculation). Examining the generation of a two-storey terrace house building, located in London, UK, the study shows that a set of building parameters combinations that resulted with a pareto front of near-optimal buildings, in terms of LCCF and LCC, could be identified by using the tool. The study shows that 80% of the optimal building’s LCCF are related to the building operational stage (σ = 2), while 77% of the building’s LCC is related to the initial capital investment (σ = 2). Analysis further suggests that space heating is the largest contributor to the building’s emissions, while it has a relatively low impact on costs. Examining the optimal building in terms compliance requirements (the building with the best operational performance), the study demonstrated how this building performs poorly in terms of Life Cycle performance. The paper further presents an analysis of various life-cycle aspects, for example, a year-by-year performance breakdown, and an investigation into operational and embodied carbon emissions.

Buildability is increasingly becoming a major requirement in building construction practice. The aim of buildability is to improve efficiency of the overall building process by developing construction sensitive designs. The objective of this study is to develop a model to assess the buildability of the buildings within Malaysian construction projects. To achieve the objective of this study, a structured interview with an expert panel, including 30 construction professionals, was conducted to compare the common buildability attributes with common construction systems for building structure in Malaysia using analytical hierarchy process (AHP). The proposed model to assess the buildability of the construction buildings was evaluated and the model was amended to fulfill the requirements of the construction industry in Malaysia. Results of this study are useful to evaluate the design of the buildings within Malaysian construction projects, thus saving time, cost, and enhancing quality.

Quantifying the environmental impacts and simulating the energy consumption of building’s components at the conceptual design stage are very helpful for designers needing to make decisions related to the selection of the best design alternative that would lead to a more energy efficient building. Building Information Modeling (BIM) offers designers the ability to assess different design alternatives at the conceptual stage of the project so that energy and life cycle assessment (LCA) strategies and systems are attained. This paper proposes an automated model that links BIM, LCA, energy analysis, and lighting simulation tools with green building certification systems. The implementation is within developing plug-ins on BIM tool capable of measuring the environmental impacts (EI) and embodied energy of building components. Using this method, designers will be provided with a new way to visualize and to identify the potential gain or loss of energy for the building as a whole and for each of its associated components. Furthermore, designers will be able to detect and evaluate the sustainability of the proposed buildings based on Leadership in Energy and Environmental Design (LEED) rating system. An actual building project will be used to illustrate the workability of the proposed methodology.

Design of seismic isolated building is often a highly iterative and tedious process due to the nonlinear behavior of the system, a large range of design parameters, and uncertainty of ground motions. It is needed to consider a comprehensive optimization procedure in the design of isolated buildings with optimized performances. This can be accomplished by applying a rigorous optimization technique. However, due to many factors affecting the performance of isolated buildings, possible solutions are abundant, and the optimal solution is difficult to obtain. In order to simplify the optimization process, an isolated building is always modeled as a shear-type structure supported on the isolated layer, and the optimal results are the parameters of the isolated layer which could not be used as a practical design of the isolated structure. A two-stage optimization method for designing isolated buildings as a practical and efficient guide is developed. In the first stage, a 3D isolated building model is adopted that takes into account of nonlinear behavior in building and isolation devices. The isolation devices are simplified as a kind of lead-rubber bearing. The genetic algorithm is used to find the optimal parameters of the isolated layer. In the second stage, the location parameters of isolation bearing layout are optimized. Moreover, the cost of the isolation bearing layout should be as low as possible. An integer programming method is adopted to optimize the number of each type of isolator. Considering vertical bearing capacity of isolators and the minimum eccentricity ratio of the isolated layer, the optimal bearing layout of the isolated building can be obtained. The proposed method is demonstrated in a typical isolated building in China. The optimum bearing layout of the isolated building effectively suppresses the structural seismic responses, but the cost of the isolated layer might slightly increase.

Life Cycle Assessment (LCA), developed over 30 years ago, has been helpful in addressing a growing concern about the direct and indirect environmental impact of buildings over their lifetime. However, lack of reliable, available, comparable and consistent information on the life cycle environmental performance of buildings makes it very difficult for architects and engineers to apply this method in the early stages of building design when the most important decisions in relation to a building’s environmental impact are made. The LCA quantification method with need of employing complex tools and an enormous amount of data is unfeasible for small or individual building projects. This study discusses the possibility of the development of a tool that allows building designers to more easily apply the logic of LCA at the early design stage. Minimising data requirements and identifying the most effective parameters that promise to make the most difference, are the key points of simplification method. The conventional LCA framework and knowledge-based system are employed through the simplification process. Results of previous LCA studies in Australia are used as the specific knowledge that enable the system to generate outputs based on the user’s inputs.Keywords: Life Cycle Assessment (LCA), early design stage, most effective parameters, life cycle environmental performance

Purpose The purpose of this paper is to present a review of the implications building information modelling (BIM) is having on the building energy modelling (BEM) and design of buildings. It addresses the issues surrounding exchange of information throughout the design process, and where BIM may be useful in contributing to effective design progression and information availability. Design/methodology/approach Through review of current design procedures and examination of the concurrency between architectural and thermophysical design modelling, a procedure for information generation relevant to design stakeholders is created, and applied to a high-performance building project currently under development. Findings The extents of information key to the successful design of a buildings energy performance in relation to its architectural objectives are given, with indication of the level of development required at each stage of the design process. Practical implications BIM offers an extensible medium for parametric information storage, and its implementation in design development offers the capability to include BEM parameter-integrated construction information. The extent of information required for accurate BEM at stages of a building’s design is key to understanding how best to record performance information in a BIM environment. Originality/value This paper contributes to the discussion around the integration of concurrent design procedures and a common data environment. It presents a framework for the creation and dissemination of information during design, exemplifies this on a real building project and evaluates the barriers experienced in successful implementation.

Purpose Design teams have difficulties in assessing building carbon emissions at an early stage, as most building energy simulation tools require a detailed input of building design for estimation. The purpose of this paper is to develop a user-friendly regression model to estimate carbon emissions of the preliminary design of office buildings in the subtropics by way of example. Five sets of building design parameters, including building configuration, building envelope, design space conditions, building system configuration and occupant behaviour, are considered in this study. Design/methodology/approach Both EnergyPlus and Monte Carlo simulation were used to predict carbon emissions for different combinations of the design parameters. A total of 100,000 simulations were conducted to ensure a full range of simulation results. Based on the simulation results, a regression model was developed to estimate carbon emissions of office buildings based on preliminary design information. Findings The results show that occupant density, annual mean occupancy rate, equipment load, lighting load and chiller coefficient of performance are the top five influential parameters affecting building carbon emissions under the subtropics. Besides, the design parameters of ten office buildings were input into this user-friendly regression model for validation. The results show that the ranking of its simulated carbon emissions for these ten buildings is consistent with the original carbon emissions ranking. Practical implications With the use of this developed regression model, design teams can not only have a simple and quick estimation of carbon emissions based on the building design information at the conceptual stage but also explore design options by understanding the level of reduction in carbon emissions if a certain building design parameter is changed. The study also provides recommendations on building design to reduce carbon emissions of office buildings. Originality/value Limited research has been conducted to date to investigate how the change of building design affects carbon emissions in the subtropics where four distinct seasons lead to significant variations of outdoor temperature and relative humidity. Previous research also did not emphasise on the impact of high-rise office building designs (e.g. small building footprint, high window-to-wall ratio) on carbon emissions. This paper adds value by identifying the influential parameters affecting carbon emissions for a high-rise office building design and allows a handy estimate of building carbon emissions under the subtropical conditions. The same approach may be used for other meteorological conditions.

Due to the ozone layer depletion, global warming and climate change, there is a significant increase to reduce carbon emission. Practitioners and academia undertake studies to promote environmentally friendly built environments. Developed countries have established specific standards to achieve a carbon neutral as their commitment to contribute for a better earth condition. Design phases are considered as the early stage where the environmental approach needs to be applied to predict the building performance as soon as possible to maximise the energy efficiency of the proposed building. Another significant factor affecting the building energy performance is climate. Climate becomes the first parameter to generate building proposals as it is contextual to the site. This study aims to assess the application of environmental approach in designing educational building in temperate climate during the early design stage. The combination of design and simulation during the early design stage, helps to define the best design proposal to adopt passive design that harvest the environment condition as much as possible to deliver comfort into the building.

Building energy waste has become one of the major challenges confronting the world today, so specifications and targets for building energy efficiency have been put forward in countries around the world in recent years. The schematic design stage matters a lot for building energy efficiency, while most architects nowadays are less likely to make energy efficiency design decisions in this stage due to the lack of necessary means and methods for analysis. An integrated multi-objective multivariate framework for optimization analysis is proposed for the schematic design stage in the paper. Here, the design parameters of the building morphology and the design parameters of the building envelope are integrated for analysis, and an integrated performance prediction model is established for low-rise and medium-rise residential buildings. Then, a comparison of the performance indicators of low-rise and medium-rise residential buildings under five typical urban climatic conditions is carried out, and the change patterns of the lighting environment, thermal environment, building energy demand, and life cycle cost of residential buildings in each city under different morphological parameters and design parameters of the building envelope are summarized. Specific analysis methods and practical tools are provided in the study for architectural design to ensure thermal comfort, lighting comfort, low energy consumption, and low life-cycle cost requirement, and this design method can inspire and guide the climate adaptation analysis and design process of low-rise and medium-rise residential buildings in China, improve architects’ perception of energy-saving design principles of low-rise and medium-rise residential buildings on the ontological level, as well as provide them with a method to follow and a case to follow in the actual design process.

There is currently an increasing demand for Building Information Modelling (BIM) to be integrated into green projects. BIM is able to evaluate green building assessment tools by digitising and assessing buildings during their development stage. In Malaysia, the Green Building Index (GBI) promotes sustainability in the built environment. Six categories of criteria will be assessed in three of the certification stages. This study focuses on how BIM applications can digitise the GBI criteria for GBI processes. It examines BIM uses and tools of each GBI credit and defines the responsibility and role of construction stakeholders in using BIM to examine the assessment methods used for new non-residential building construction based on GBI. The primary method for data collection is the focus group interview which involves the groups of stakeholders involved in a BIM and GBI project. The result of the BIM–GBI assessment method showed that BIM could digitise and assess 25 credits in Design Assessment (DA), which can achieve 55 points of the total 100 points. This study helps stakeholders define the design team and facility manager’s roles to obtain GBI certification and maintain the certification during the building’s operation stage.

Purpose Buildings and their construction activities consume a significant proportion of mineral resources excavated from nature and contribute a large percentage of CO2 in the atmosphere. As a way of improving the sustainability of building construction and operation, various sustainable design appraisal standards have been developed across nations. Albeit criticism of the appraisal standards, evidence shows that increasing sustainability of the built environment has been engendered by such appraisal tools as Building Research Establishment Environmental Assessment Method (BREEAM), Code for Sustainable Homes (CfSH), Leadership in Energy and Environmental Design and Comprehensive Assessment System for Built Environment Efficacy, among others. The purpose of this paper is to evaluate the effectiveness of the appraisal standards in engendering whole lifecycle environmental sustainability of the built environment. Design/methodology/approach In order to evaluate the adequacy of sustainability scores assigned to various lifecycle stages of buildings in the appraisal standards, four case studies of a block of classroom were modelled. Using Revit as a modelling platform, stage by stage lifecycle environmental impacts of the building were simulated through Green Building Studio and ATHENA Impact estimator. The resulting environmental impacts were then compared against the assessment score associated with each stage of building lifecycle in BREAAM and CfSH. Findings Results show that albeit the consensus that the appraisal standards engender sustainability practices in the AEC industry, total scores assigned to impacts at each stage of building lifecycle is disproportionate to the simulated whole-life environmental impacts associated with the stages in some instances. Originality/value As the study reveals both strengths and weaknesses in the existing sustainability appraisal standards, measures through which they can be tailored to resource efficiency and lifecycle environmental sustainability of the built environment are suggested.

The goal of sustainable construction is to improve the energy efficiency of a building, which today is a challenge for software developers, builders, owners within the constraints of time, cost, provision and resources. Building functional, sustainable, safe, comfortable and easy-to-use buildings will increase consumer demand. The problem of implementing sustainable construction lies in the division of responsibilities and tasks from the relevant specialists. This article explores the role of Building Information Modeling (BIM) in reducing fragmentation among professionals at every stage of construction. The possibility of using a virtual storage of information using BIM is analyzed, which provides easy access to data and their exchange in real time. Thus, BIM provides a professional platform for working in an integrated environment at any stage of the building construction process. When analyzing Russian and foreign sourcesthe prerequisites are being created for the future research required to generate improvements towards sustainable construction.

The analyzed research issue provides a model for Carbon Footprint estimation at an early design stage. In the context of climate neutrality, it is important to introduce regenerative design practices in the architect’s design process, especially in early design phases when the possibility of modifying the design is usually high. The research method was based on separate consecutive research works–partial tasks: Developing regenerative design guidelines for simulation purposes and for parametric modeling; generating a training set and a testing set of building designs with calculated total Carbon Footprint; using the pre-generated set to train a Machine Learning Model; applying the Machine Learning Model to predict optimal building features; prototyping an application for a quick estimation of the Total Carbon Footprint in the case of other projects in early design phases; updating the prototyped application with additional features; urban layout analysis; preparing a new approach based on Convolutional Neural Networks and training the new algorithm; and developing the final version of the application that can predict the Total Carbon Footprint of a building design based on basic building features and on the urban layout. The results of multi-criteria analyses showed relationships between the parameters of buildings and the possibility of introducing Carbon Footprint estimation and implementing building optimization at the initial design stage.

Due to the scarcity of water and the harsh desert climate of the United Arab Emirates (UAE), water and energy are two of the main challenges for the design of sustainable buildings in the UAE. Relevant literature calls for the consideration of building systems and materials at the design stage to achieve high-performing buildings and to save on the operational costs of the building. The aim of this research was to design a high-performance building that meets the environmental sustainability requirements for water and energy, in the city of Dubai to reflect the technological advancements of the UAE Mars mission. This has been achieved through following an integrated design process, which was mainly focused on the evaluation and specification of the building engineering systems based on performance, besides the goal of achieving visually appealing building with advanced structural design. The performance verification of the final building design, which considered engineering systems design from conception and through the design and detailed design stages, revealed a 15% reduction in water consumption and a 60% reduction in energy consumption. This provides a valuable contribution to architectural engineering practice, by demonstrating a case study for enhancing energy and water efficiency via building design, which consequently contributes to the environmental sustainability of the built environment.

BIM -Building Information Modeling is the fastest growing branch of modern design and execution of buildings. In the United States there is a requirement for the design of public investment based on BIM technology. Similar legislation has been in force since 2016 in the United Kingdom. In the near future also in Poland, it becomes necessary the use of BIM technology in the implementation of investments co-financed from European Union funds. The most important part in the design of a new approach is the treatment of structural parts of geometric models, as information which can be changed as desired at any stage of design. A comprehensive approach to design using BIM technology allows to carry out a series of analysis and collision detection at the design stage, in order to reduce costs at the stage of execution of the investment. The paper presents the design of the structural part of a reinforced concrete building, multi-storey in BIM technology. It uses an innovative design approach, enabling the analysis of the object using CAD (Computer Aided Design), which previously was based BIM method and a new approach based on the method of CAE (Computer Aided Engineering), which permit the object generated in BIM, static-strenght analysis. The article presents opportunities and benefits of BIM methods, using innovative design CAE/CAD.

Developments in information technology are providing methods to improve current design practices, where uncertainties about various design elements can be simulated and studied from the design inception. Energy and thermal simulations, improved design representations and enhanced collaboration using digital media are increasingly being used. With the expanding interest in energy-efficient building design, whole building energy simulation programs are increasingly employed in the design process to help architects and engineers determine which design strategies save energy and improve building performance. The purpose of this research was to investigate the potential of these programs to perform whole building energy analysis during the early stages of architectural design, and compare the results with the actual building energy performance. The research was conducted by simulating energy usage of a fully functional research laboratory building using two different simulation tools that are aimed for early schematic design. The results were compared with utility data of the building to identify the degree of closeness with which simulation results match the actual energy usage of the building. Results indicate that modeled energy data from one of the software programs was significantly higher than the measured, actual energy usage data, while the results from the second application were comparable, but did not correctly predict monthly energy loads for the building. This suggests that significant deviations may exist between modeled and actual energy consumption for buildings, and more importantly between different simulation software programs. Understanding the limitations and suitability of specific simulation programs is crucial for successful integration of performance simulations with the design process.

Understanding issues early in the integrated design process is important, as this is when designers and engineers are able to have the largest impact on the final product. In this article the technology of conceptual architectural design for low energy buildings is proposed to address this issue. Here two methods – Quality function Deployment and Axiomatic design are used to develop the conception and to eliminate the main disadvantages of traditional building design. The integration of BIM, energy modelling (DesignBuilder) help to highlight the issue of energy efficiency at the early stage of building design, resulting in effective and more to posed requirements orientated design process.

Green Building rating tools are the essential need of this era, to cope up with the sustainable development goals, climate change, and natural resource degradation through buildings. Realization of green building incentives decently increased within past few decades with abrupt declination in real estate markets and economic depletion has decelerated the interest of investors towards the green building projects. This research calculates influence of costing elements in MyCREST (IS-design) using questionnaire survey distributed amongst qualified professionals (QP’S) of green buildings and expert practitioners. Firstly, factor score and then weightage factor was performed to produce the final result with weightage output for evaluating weighatge and ranking of the relevant criteria of MyCREST and life cycle cost elements respectively. It is found that the criteria of storm water management has weighatge of 0.236 as highest and criteria environmental management plan (EMP) as 0.061 as lowest. Research also identified another perspective by finding association of cost element at design stage of MyCREST and found that management cost is highly associated at design stage with the value of 87.7%. The outcome of this research will add value to green building development and map road towards sustainable development using green building tools to uplift quality of life. Furthermore, this paves a way to integrate various stages of MyCREST with life cycle costing tool to potentially contribute in evaluating cost association through green building rating tool.

Any construction project through several stages, starting from the feasibilitystudy stage to the project delivery stage, as the most critical stage that must be focused on is the design stage. It was essential to adopt modern and advanced programs at the design stage to avoid problems and claims between the employer and the contractor due to changes and errors that occur in the project—design process. BIM is one of the modern technologies with many benefits that can be used to solve these errors and obstacles. This research aims to clarify the effectiveness of introducing the BIM system in the design stage of the construction building by comparing it with traditional CAD systems. In this research, ten different actual projects were studied in the architectural design stage to be used in the comparison process between BIM and CAD systems. The researcher reached a set of results, including that introducing the (BIM) in the architectural and structural design stage can reduce the time required to produce design documents by up to (67.6%). This study is helpful for all governmental and private design companies and encourages decision-makers to use the BIM system.

Energy-efficient building retrofits must be approached from three perspectives: law regulation approach, financial incentives approach, and practice approach. The concepts of zero energy building and life cycle energy building are presented as the basis for energy retrofits. Multi-criteria boards to assess the decision-making process are reviewed, analysed, and categorised under an architectonic perspective. Some examples are presented, with different packages of measures, from deep to non-invasive energy retrofits. Passive and active energy generation systems, together with control and management strategies, are the physical elements identified with the potential to improve buildings’ energy efficiency. From a practice approach, this literature review identifies the concept of performance-based architectural design to optimise the planning and design of buildings’ energy retrofits. In addition, tools such as Building Information Modelling are described as part of optimisation processes, as they enable designers to rapidly analyse and simulate a building’s performance at the design stage.

PurposeTraditionally, early-stage investment decisions on buildings purely based initial capital costs and simply ignored running costs and total lifecycle cost. This was basically due to the absence of estimating models that yield running costs at the early design stage. Often, when the design of a building, which is responsible for 10–15% of its total cost, is completed, 80% of the total cost is committed. This study aims to develop a building characteristic-based model, which is an early-stage determinant of running costs of buildings, to predict the running costs of commercial buildings.Design/methodology/approachA desk study was carried out to collect running costs data and building characteristics of 35 commercial buildings in Sri Lanka. A Pareto analysis, bivariate correlation analysis and hedonic regression modelling were performed on collected data.FindingsAccording to Pareto analysis, utilities, services, admin work and cleaning are four main cost constituents, responsible for 80% of running costs, which can be represented by highly correlated building characteristics of building height, number of floors and size. Approximately 94% of the variance in annual running costs/sq. m is expressed by variables of number of floors, net floor area and working hours/day together with a mean prediction accuracy of 2.89%.Research limitations/implicationsThe study has utilised a sample of 35 commercial buildings due to non-availability and difficulty in accessing running cost data.Originality/valueEarly-stage supportive running costs estimation model proposed by the study would enable construction professionals to benchmark the running costs and thereby optimise the building design. The developed hedonic model illustrated the variance of running costs concerning the changes in characteristics of a building.

While design optimization of buildings seeks to improve energy efficiency and, thus, leads to greenhouse gas emissions reduction, the thermal performance of buildings can be compromised. Thermal performance is an important aspect as it directly affects the health and well-being of occupants. This study aims to investigate using a simple simulation tool to examine the correlation between a set of building physical design parameters such as orientation, shading and shape, optimization of which helps to make a positive impact on the thermal performance of the building in a cold climate zone. The thermal performance simulation tool Passive Design Assistant (PDA) was used to build a simulation model and test the interdependence between the design parameters and thermal performance. The results indicate that modifications of building’s parameters such as orientation and shape or the addition of shadings lead to improvements of the internal thermal temperature, heat gain and loss, hence the optimal parameters should prevail. A case study for cold climate is analyzed, in Nur-Sultan, Kazakhstan, the optimal orientation for the squared building is 30° from East to South (building rotated 120°) and the optimal building’s shape is rectangular, which attracts up to 2.6 times higher solar gains than the square one. Moreover, the use of shadings can regulate the internal temperature of the building by 2 °C. General recommendations based on the findings are made and could be considered in the earlier stage of building design and construction processes.

This study suggests the design construction process of green buildings based on the construction process for green buildings in Korea. In this construction process, the planning purpose lies in the CO2 reduction of each element technology not considered during the general building construction processes and energy saving construction processes and that of overall buildings. The interaction of each element technology was considered so that evaluation and feedback could be provided at each stage. Different from existing construction processes, CO2 reductions were evaluated and fed back at each stage and alternative designs could be selected to draw the optimal design.

The paper describes a simple design tool for architects to estimate daylight performance of high-rise residential buildings in high-density urban sites during the early design stage. The tool is based on a modified version of the original split flux formulae. The tool resolves the formulae to a set of tables relating vertical obstruction angles with horizontal obstruction angles. Given the geometrical properties and the required daylight performances, an architect could work out, at the early design and planning stage, the design configuration of the building block itself, the spacing between building blocks, and the sizes of windows required. Working examples demonstrate how the tool might be used in design.

The procedures of solving them are considered to be possible variants for BIM-scenarios usage. The main goal of the study is demonstration of an example of using algorithmic design for the object operation stage. In this article we formulated and analyzed BIM-scenarios for the building operation stage at the building technical condition monitoring sub-stage and we offered to use tools for algorithmic design to automate implementation of processes of a considered scenario and also formed the main conclusions for the presented study.
