The increasing urbanization of the built environment has bolstered the need to promote green Building Information Modeling (BIM) initiative in new construction projects and the rehabilitation of old premises. This study aims to explore and examine the key benefits of the implementation of BIM and sustainability practices in the built environment.

The study gathered the worldwide perceptions of 220 survey participants from 21 countries which were analyzed using descriptive and inferential analytical methods. The identified individual benefits of green BIM were further categorized into their underlying clusters using factor analysis.

The key benefits are related to enhancing project efficiency and productivity, ensuring real-time sustainable design and multi-design alternatives, facilitating the selection of sustainable materials and components, together with reducing material wastage and project’s environmental impact, among others. The study analyzed and compared the perceptions of the diverse groups of the respondents as well.

Effective blueprints and insightful recommendations for enhancing the various stakeholders’ capacities to implement green BIM in their construction projects were put forward to achieve the aim of sustainable smart urbanization.

The study identified salient benefits of the adoption of BIM and sustainability practices. The proper integration of these concepts and the execution of the recommended useful strategies by construction stakeholders, policymakers and local authorities will enable the built environment to reap the gains of its implementation.

Laboratories typically consume 4‐5 times more energy than similarly‐sized commercial space. This paper adds to a growing dialogue about how to “green” a laboratory's design and operations.

The paper is divided into three sections. The first section reviews the background and theoretical issues. A case is made for sustainable laboratories, introduce the Harvard Green Campus Initiative's (HGCIs) study of potential energy reduction in Harvard's research laboratories and examine other issues including: behavioral change, technical change, and the required codes and suggested standards that influence laboratory design and operations. Next, a survey conducted through a partnership between HGCI, Harvard School of Public Health (HSPH), and Laboratories for the twenty‐first century (Labs21) to clarify issues surrounding use of codes and standards in high‐performance laboratory design and maintenance is introduced.

Survey findings highlight the confusion among survey participants surrounding the applications and interpretations of current lab guidelines, codes and standards, particularly addressing sustainable performance. The findings suggest that confusion has financial, environmental, and human health consequences, and that more research is needed to define the operational risks to laboratory workers. Findings indicate that many energy efficient technologies and strategies are not routinely specified in lab design, perhaps in part due to confusion concerning the guidelines, standards and codes.

Although the survey sample size is too small to be statistically significant, it does provide valuable insight into the general confusion surrounding the applications and interpretations of current codes and guidelines, especially those addressing sustainable performance.

The practical implications of this research are many, including that there are many opportunities for technical and behavior improvements within modern university laboratories that yield great energy savings. This is critical as laboratories are one of the most energy‐intense building types on a university campus.

The critical originality of the paper is provided in the analysis of the obstacles to achieving the great potential energy savings that exist within the university laboratory context.

Buildings, which account for approximately half of all annual energy and greenhouse gas emissions, are an important target area for any strategy addressing climate change. Whilst new commercial buildings increasingly address sustainability considerations, incorporating green technology in the refurbishment process of older buildings presents many technical, financial and social challenges. This paper aims to explore the social dimension, focusing on the perspectives of commercial office building tenants.

Semi‐structured in‐depth interviews were conducted with seven residents and neighbours of the case‐study building undergoing green refurbishment in Melbourne, Australia. Responses were analysed using a thematic approach, identifying categories, themes and patterns.

Commercial property tenants are on a journey to sustainability. Tenants are interested and willing to engage in discussions about sustainability initiatives, but the process, costs and benefits need to be clear.

The findings, while limited by non‐random sampling and small sample size, highlight that the commercial property market is interested in learning about sustainability in the built environment.

The findings highlight the importance of developing a strong business case and transition plan for sustainability in commercial buildings. As sustainable buildings become mainstream, tenants predicted the emergence of a “non‐sustainability discount” for residing in buildings without sustainable features.

This research offers a beginning point for understanding the difficulty of integrating green technology in older commercial buildings. Tenants currently have limited understandings of technology and potential building performance outcomes, which ultimately could impede the implementation of sustainable initiatives in older buildings.

The purposes of this paper are to: investigate schedule performance of new and retrofitting green building projects; identify the critical factors that influence the schedule performance of new and retrofitting green building projects; and provide solutions to improve schedule performance of new and retrofitting green building projects.

A questionnaire survey were conducted and responses were received from 34 firms experienced in green building projects in Singapore. After the data from the survey had been analyzed, face-to-face interviews were conducted with two senior project managers to solicit comments on the survey results.

This study identified the degree of project delay in 98 new green building projects and 51 retrofitting green building projects in Singapore. The result indicated that 22 percent of the Singaporean green building projects were plagued with delay and retrofitting projects had a significantly higher likelihood of delay and significantly longer extension than new projects. In addition, “consultant cooperation to solve problems” was the most influential to schedule performance of both new and retrofitting green building projects, and the two project groups agreed on the overall ranking of the factors affecting schedule performance.

There may be geographical limitation on the conclusions drawn from the findings. Also, the sample size was still small, despite a relatively high response rate. In addition, the majority of the respondents were contractors as other project players were reluctant to respond to the survey.

This study provides a clear understanding of the schedule performance of green building projects as well as the critical factors that should be highlighted when constructing green building projects. Also, strategies to overcome the negative impact of these factors allow practitioners to better deal with the potential causes of delay and to attain the schedule performance.

Although construction delays have been widely investigated in previous studies relating to construction management, few have attempted to analyze the schedule performance of new and retrofitting green buildings. Thus, this study adds significantly to the existing research on both green building and construction delay.

The sustainable green movement is significantly gaining momentum around the globe and South Africa needs to follow suit. However, such a movement needs to be significantly tested. It is therefore essential to present both foundation and supplementary research in the primary concepts within this topic in order to lay the groundwork for future analysis. The purpose of this paper is to analyse the cost‐effectiveness of the heat recovery ventilation (HRV) technology incorporated within Lincoln on the Lake, against a direct‐expansion (DX) ducted system of conventional practice utilising the life cycle cost analysis (LCCA) to determine if the sustainable option is the better choice.

This paper is a case study, based on a green building in KwaZulu‐Natal, South Africa using a ten step life cycle cost analysis.

In terms of the LCCA performed at Lincoln on the Lake, this case study has found that sustainable measures were far more cost effective over the 20 year study period than that of the comparable conventional system. The life‐cycle cost analysis tool has provided a simple, uniform and predetermined manner for which the life‐cycle costs of sustainable designs can be successfully quantified.

The value which sustainable building practices can pose, has not been fully realised among clients and professionals within the South African construction industry due to lack of proof that value incentives do exist. This paper, therefore, emphasizes that savings can be made over the long term by going the sustainable route.

Literature review indicates that Leadership in Energy and Environmental Design – Accredited Professionals (LEED APs) practicing during the first ten years of LEED in the building industry hold perceptions that have influenced the adoption of LEED. These perceptions may include that some LEED credit points are more difficult to obtain than others, LEED projects have higher first costs, and LEED projects have higher levels of complexity. The literature also indicates that the relationship between these three topics merits research attention, in an effort to discover the magnitude of those perceptions. This paper aims to address these issues.

Both self‐administered questionnaires and interviews are utilized to secure information directly from practitioners. Out of a pool of 8,000 possible interviewees, a total of 102 qualified respondents participated in the cross‐sectional survey. Statistical Package for the Social Sciences (SPSS) software is used to analyze the data derived from the survey information and to arrive at conclusions.

The survey identify which LEED credit points are perceived by LEED APs as more difficult, as contributing to higher initial costs and as increasing project complexity. The conclusions indicate a trend toward a higher adoption rate of points that are perceived as having lower initial costs and a lower level of complexity. These findings are primarily due to two reasons: increased cost in managing project documentation; and increased cost in project complexity.

The results of this study can be used by designers, construction professionals, and facility managers who are involved in new construction projects. The trends in credit point adoption, and the professionals' perceptions of their initial cost and level of complexity, may encourage others to consider using systems that introduce sustainability concepts into their design and construction process.

The research investigates valuers' understanding of the value of sustainability in property and its' consideration in valuation practice in Australia. This paper explores valuers' perceptions of the relationships between sustainability and market values, sustainability and valuation variables, and the value influence of industry sustainability certification schemes. Further, this paper tracks prevalence of certified buildings in Australian commercial markets and the evolution of valuers' knowledge of sustainability certifications used in Australia.

This paper reports on the next rendition of a longitudinal study examining valuers’ practice in Australia. This research explores the evolution of Australian valuers' perception and knowledge of sustainability in valuation practice. The survey data has been periodically collected from practising valuers from 2007 to 2021. The survey questions investigate valuers' knowledge development, understanding, reporting and consideration of the relationship between sustainability and market value.

The results have identified the evolution of the influence of normative research on valuers' perceptions of the relationship between sustainability and value; with a clearer understanding emerging over time of where the value relationships are identified in valuation variables. Greater alignment between empirical Australian studies and valuers' perceptions of the influence of sustainability ratings on value, demonstrate the value connection for higher rated buildings under NABERS (energy rating) and Green Star. Whilst only 41% of the study's participants are including sustainability in their valuation reports, they include a higher level of commentary on building descriptions and initiatives, building ratings, and reporting of owner and tenant objectives, than in previous studies. Knowledge development relating to sustainability certification tool, NABERS was identified. This is likely linked to the introduction of mandatory disclosure legislation. This has also led to increased awareness and valuers' knowledge of the differences between the two key rating tools used in Australia.

The research has several limitations: firstly, recruitment of valuers and the number of valuers' responses has varied over time; secondly, due to collection methods respondents have a greater likelihood of having an interest in and knowledge of sustainability creating potential for positive bias; thirdly, respondents may have responded to the survey in different years, but due to anonymity there has been no ability to track this. The results provide insights into the Australian valuation profession but may not be fully representative of the profession overall in Australia.

The broader agenda of net zero, climate change, mitigation and carbon requirements, whether driven by market forces or government legislation, are generating changes in property markets as investors' reconsider their positions and model the implications of carbon emissions on their bottom lines. Introductions of policy and legislation over time in the Australian context have led to changes in valuation practice and increasing consideration of energy efficiency and ratings in the valuation of assets. However, further guidance and research still is required in Australia to assist in the knowledge development of valuers, and their ability to consider the emerging effects of sustainability, net zero and other market driven objectives including legislation, and how these may affect or influence their evaluation of market evidence and thus property values.

The research has tracked valuers' understanding, knowledge, and consideration of sustainability and energy efficiency in valuation practice since 2007. In that time the research has found that, as the market has evolved and more rated buildings are built (or retrofitted), so too has valuers' knowledge and consideration in valuation practices evolved. Valuers are more engaged with industry rating tools such as NABERS. This suggests that the Australian mandatory disclosure policies have contributed to changes in the market, which are then interpreted by valuers and reflected in their perceptions and consideration of energy ratings in valuation practice.

The key to green building (GB) success is to have GB expansion driven by consumer demand rather than enforced rules and regulations. Yet, only a few studies have focused on the market impediments to GB development. This study systematically identified and evaluated the critical impediments to the demand for green and sustainable architecture by construction clients in Ghana.

The study adopted a two-stage data gathering approach. Qualitative data was collected first through an interview administered to 18 construction clients in Ghana. Based on the early findings, a survey instrument was subsequently developed to seek the views of 120 GB experts and professionals with 96 valid responses-returned.

The study discovered that – ineffective advertisement of GB, the perceived cost of implementation, lack of expertise, lack of financial incentives, illiterate construction market and risk and uncertainties were the top six reasons for the low demand for GB by construction clients in Ghana

Findings from this research would guide industry practitioners and stakeholders to make informed decisions regarding how to stimulate demand for GBs among construction clients.

The paper models and presents contextual realities on barriers to GB demand in Ghana. The study has added to previous studies by unearthing what constitutes the lack of demand for sustainable architecture. The findings of this study are expected to provide valuable information and insight to policymakers to catalyze green construction by actively involving construction clients.

This paper aims to investigate the benefits derived from sustainable office buildings in People’s Republic of China (PRC) through their green features, with particular reference to energy efficiency.

A survey on operating costs, energy impacts, productivities from property managers and tenants of sustainable office buildings was conducted in Shenzhen, PRC. All survey data were collected from a portfolio of 12 sustainable office buildings and from 76 responses out of more than 400 tenants who had moved into these buildings from conventional office buildings.

Most tenants were concerned with sustainable operations, practices and policies. Some of them held that sustainable office buildings contribute to higher productivity and less sick time. These buildings typically consume less electricity and water, and have higher occupancy rates and rents.

There are only 40 sustainable office buildings in Shenzhen, and our study, albeit with proper methodology, with 12 sample buildings may not reflect entirely the attitudes of tenants and property managers of sustainable office buildings in Shenzhen. Advisably, future works can be carried out on a larger scale in other main cities of PRC to obtain a more comprehensive and precise evaluation on which strategic sustainable central/local government policies might be formulated.

The concept of facilities management on sustainable buildings, especially on their derived benefits, is relatively new in developing countries such as China. This study is one of the first attempts in this area. In addition, this paper also contributes to existing literature by looking into the green lease provisions and operating policies of these sustainable buildings.

The purpose of the study is to estimate the potential of end‐user effect on energy conservation in office buildings. The study quantifies the energy conservation potential and estimates the current level of energy management in four banking organisations in the Nordic countries.

The multiple case study employs quantitative scenario analysis for estimating the energy conservation potential of office equipment and lighting, and uses a qualitative model for estimating the current level of end‐user energy management in the organisations.

The study found that noticeable potential for energy conservation exists in the end‐user energy consumption. The tested scenarios significantly decreased the yearly electricity consumption of office equipment, for some 70 per cent, from 21 kWh per m² to 6 kWh per m². The electricity consumption of lighting was also noticeably improved, for some 30 per cent, from 38 kWh per m² to 27 kWh per m², equalling a 29 per cent reduction there. Altogether, the identified savings equal an improvement of roughly 20 per cent in the overall electricity consumption of the organisations. At the same time, the evaluation of current energy management showed that the management practices implemented represent only a rather modest level of end‐user energy management.

The multiple case study focused on four Nordic countries and banking organisations only. As the banking sector tends to be more conservative than some other industries, the results are not necessary valid in all industries. The simulation tools used, especially for lighting, only give estimation of the “best case” type of situation for tested scenarios, in which it is assumed that all end‐users would start to behave according to the scenario.

This study implies clearly that end‐user‐energy‐management services are needed in FM. Although the user behaviour is more challenging to manage than pure technology, it can be quite profitable. For example, in the studied organisations, the savings found in end‐user energy would equal yearly profits of roughly 1.7 million €, i.e. some 20 per cent of the overall electricity budgets of the companies.

Most of the quantitative energy conservation studies in the offices have concentrated so far on new constructions and building system improvements. This study quantifies the potential influence of good facilities management with the end‐user activation on the energy efficiency of office buildings.
