Despite substantial advances in technologies enhancing the energy efficiency of buildings, they remain the largest consumers of energy in the USA compared with other sectors. In addition, the current rating systems for sustainable buildings do not reflect all potential energy savings during the design, construction, and occupancy of the built environment. The purpose of this paper is to examine the application of multi-attribute utility theory (MAUT) as a framework for quantifying energy decisions made during the design phase of a building construction project.

The MAUT method was applied to a case study, and the results were compared with subjective results from the decision makers. Analysis of the results suggested that MAUT is a decision analysis tool that could aid decision makers in communicating their decision criteria and expectations.

Findings from this research suggest that using an analysis method provides the decision makers with a systematic way to include their concerns and preferences and specific requirements of the project along with the criteria for sustainable energy and the built environment at the same time. Using a multi-criteria, decision-making method provides the decision makers with quantitative information, which facilitates the comparison of alternatives. MAUT enabled the various stakeholders of the project to collaborate on the inputs of the problems and allowed the decision makers to communicate their priorities and expectations more effectively.

The findings indicated that MAUT provides stakeholders with a quantitative and holistic approach to decision making in which they can track changes in parameters during the process. The implementation of MAUT as a decision analysis tool in designing construction projects ultimately could lead to better decision making for sustainable building designs.

The purpose of this study is to examine the feasibility of using 3D simulation transfer processes to streamline the environmental assessment of buildings that have been designed digitally using building information modelling (BIM). The case study presented relates to a competition (“Build Qatar Live”) in which one of the winning team’s objectives was to create a smart process for assessing the design against the Leadership in Energy and Environmental Design (LEED) criteria. The experience indicated that a rapid, concurrent and efficient LEED evaluation was possible within the BIM process. The study presents technological approaches that can be adopted within the BIM environment to simplify the environmental assessments and embrace practices that reduce environmental and ecological impacts.

The methodology encompassed an overview of how rapid high-value data exchange occurs within BIM to achieve a sustainable building design as part of an international design competition. Achieving a LEED rating through sustainable design was a key requirement of the competition.

The findings of this case study has revealed that key credits in LEED can be integrated within the BIM design process. Therefore, tackling such important environmental design issues in parallel to building design and providing key information on building elements needed to meet the sustainability criteria.

This research highlights the benefits of streamlined, architectural and data software exchange through applying data interoperability of a building design; thus, skipping conventional 2D building and conventional documentation for environmental and energy designs simulations needed for LEED certifications and general low carbon design.

The purpose of this paper is to seek to contribute to the objective of the sustainable development process. A factor that may be hindering progress towards sustainable building in many developed states is the sheer complexity of the instruments available and the convoluted nature of policy. Acknowledging this difficulty, this article questions whether a simplified, integrated structure to coordinate policy and instruments is feasible. Compared with many developed nations, New Zealand's approach to sustainable construction and buildings is de minimis. The New Zealand Government is, at present, reviewing building legislation and policy in order to incorporate, inter alia, the objective of sustainable development.

The article employs a literature review.

This article proposes a simple, practical structure for integrating policies and instruments that are aimed at facilitating sustainable construction and buildings. It concludes that New Zealand is in a prime position to develop this structure within which to propel industry and consumers forward, towards achieving sustainability in building.

This paper aims to stimulate discussion and development of the proposed structure.

The article draws upon the experience of European states, in particular, and acknowledges that existing instruments, carefully coordinated, can maximise the progress towards sustainable buildings. The resulting concept could be used by any state.

With the impending development of green buildings in Kuala Lumpur, the capital city of Malaysia, managing the criteria within the requirements of the rating tool’s certification shall be the responsibility of the respective parties when these buildings are in operations. In tenanted buildings, a lease agreement spells out the responsibilities of the owner/landlord and the tenants. The paper aims to discuss these issues.

The main aim of this study is to gauge the implementation of green lease among office buildings in Kuala Lumpur. This is made through an initial review of the adoption of green building criteria as well as the determination of the drivers and barriers perceived by office building managers in implementing green lease.

A survey amongst the managers of top grade office buildings in Kuala Lumpur revealed that the majority practiced some of the green criteria outlined in the Green Building Index. It also revealed that the most significant green lease terms commonly acknowledged by the respondents were energy and water-saving consumption as well as recycled material usage.

Through the identification of the barriers to implement green lease, the most significant barriers identified were related to cost and financing. Having identified these obstacles, appropriate action can be taken to bring forward green lease awareness amongst the various stakeholders in the office building sector in ensuring the successful operation of green buildings.

The purpose of this research is to develop a building information modelling (BIM)-enabled sustainable design process model that identifies critical decisions actions in the design process along with the information and level of detail that facilitate an informed and timely decision. Building performance analysis is usually performed after the design and construction documents are produced, resulting in lost opportunities.

A number of research methods have been adopted; these include extensive literature review and 11 in-depth exploratory interviews with industry practitioners (sustainable building design experts, early BIM adopters).

Project delivery methods have a significant effect on the sustainable outcome of buildings. The development of a structured process can assist sustainable design practice among building professionals. Learning from implemented projects, that have utilised BIM processes, facilitates the scope of creating this process and advises future projects to prevent failures. Process mapping is essential to streamline the process, support key project processes and help the design team manage their own responsibilities and deliverables required by them.

The identification of the gap and the need for a structured process for sustainable building design for BIM execution is discussed. The synergies that exist between BIM, building performance modelling, Building Research Establishment’s Environmental Assessment Method assessment and the Royal Institute of British Architects Plan of Work are shown. The effect that project delivery has on sustainable design outcome has been established. A coordinated collaborative design process model is presented based on the findings from interviewing early adopters.

Sustainability in the built environment is rapidly gaining attention worldwide, although many developing countries have not accomplished much on the ground as many sustainability aspects still remain untreated. Despite their low greenhouse gas contributions to the globe, the high rate of construction activities that do not embrace sustainable practices in these countries pose challenges to the environment. Using the case of Tanzania, this study assesses the level of sustainability awareness among key stakeholders in the built environment.

The study uses a mixed-method research approach where primary data was collected using a questionnaire and semi-structured interviews with key informants comprising engineers, architects, property managers, property owners, property users and academicians from institutions of higher learning.

Results show that despite the potential for a sustainable built environment, there is a low level of awareness among key stakeholders. Whereas few architects, who were aware, admitted to have not incorporated sustainability aspects in their building design, other stakeholders did not have active roles in decision-making involving building construction projects. Compared to the rest, the awareness level of property users was the lowest. Lack of a specific policy or policy statement on sustainable building, high initial costs of sustainable building, few skilled professionals and lack of a broad choice of building materials are some of the factors accounting for the low level of sustainability adoption in the built environment.

The significance of this study lies within the objective of showing awareness levels of sustainability aspects among key built environment stakeholders and policymakers, which is important in devising strategies for promoting sustainable construction practices.

Developing countries are currently on the verge of adopting principles used in achieving a sustainable urban future. As the urban population increases due to factors like urban–rural migration, increase in birth rate, migration, industrialisation, commercialisation, amongst others, there is a drastic need to adopt sustainability principles within urban spaces. To understand how sustainability can be achieved, there is a need to recognise how developed countries have designed assessment tools that work within their context which can inform how developing countries can work on their assessment tool. Urban neighbourhood sustainability assessment tools are used to reflect on the overall goal of the project and the most important indicators needed to be implemented within the project. Sustainability indicators are used to measure the levels and progress at which sustainability has been implemented within a project based on the data collected and these results can be used to make informed decisions. The purpose of this paper is to investigate the development of urban sustainability assessment tool.

This research investigates the techniques utilised in developing an urban sustainability assessment tool Sustainable Composite Cities Environmental Evaluation and Design (SUCCEED-ND) tool within the Nigerian context. The data instrument used includes a questionnaire survey that sampled 50 correspondents, and the results were used to develop an urban assessment tool tailored for the Nigerian countries.

The findings used social, environmental, economic and planning sustainability dimensions in the design of the assessment tool which composes of 21 core sustainability indicators and 105 indicators to develop SUCCEED-ND tool.

This work developed the first urban sustainability assessment tool for the Nigerian urban environment. The result is meant to evaluate and implement sustainability within existing and proposed neighbourhood development.

Buildings/infrastructure are recognised to have a significant impact on the environment and the community, and hence there is pressure on industry practitioners to incorporate environmental and social considerations in addition to the traditional cost, time and quality. The development of sustainability reporting tools (SRTs) to assist in the management of “green” building/infrastructure projects is pivotal in informing on progress in sustainability practices. However, the rapid growth of SRTs in the last decade, with different criteria and methodology, has created complications for stakeholders.

The paper provides a comprehensive review of tools to guide practitioners, property investors, policy makers and developers towards making informed choices in “green” building/infrastructure projects. Comparative analyses, benefits and limitations of these tools are discussed in the paper.

Some of the findings from the analysis of SRTs include: an emphasis on environmental issues; scoring which does not account for uncertainty or variability in assessors’ perceptions; lack of published reasoning behind the allocation of scores; inadequate definition of scales to permit differentiation among projects; and the existence of non-scientific benchmarks.

The paper departs from earlier reviews to include a discussion on infrastructure SRTs, life cycle tools, and issues broader than the environment. Changes and additions, subsequent to earlier reviews, have been made to SRTs, making the updated review provided here useful.

System dynamics has several applications in the built environment, and few studies indicate that it has potential in evaluating sustainability. Sustainability in the built environment involves numerous entities and multiple trade-offs. Hence, a Multi-Criteria Decision-Making (MCDM) method is ideal for promoting sustainability-based decision-making in the built environment. Therefore, this study integrates system dynamics with an MCDM method to enable the sustainability assessment by capturing the time-induced dynamic changes affecting long time sustainability performance of buildings.

Conventional sustainability assessment tools in the built environment lack a comprehensive evaluation that balances the needs of the society, economy and environment. This study develops a system dynamics-based framework to enable sustainability-conscious decision-making and policy analysis in the built environment.

Various material, technology and water-related policies specific to the buildings are investigated for a case study building. It is found that the effect of penetration of renewable energy technology to the tune of 80% and above in the energy mix is a much superior policy in sustainability improvement in comparison to material and water-related policies. The study also demonstrates the effect of weights assigned for the different indicators on sustainability-based decisions.

The study provides a methodological framework for a sustainability-based decision support system for the built environment that enables dynamic performance evaluation by coupling system dynamics with the MCDM. This coupling further strengthens system dynamics as a decision-making and policy analysis for sustainability evaluation in the built environment.
