Sustainable design and construction introduces another layer of complexity to project delivery processes for buildings. To achieve increased efficiencies and improved environments, project teams seek to optimize building systems through the iterative process of integrated design. These sustainable delivery methods are maturing, and there is a growing population of sustainable buildings in operation. Thus, a fundamental question arises—are sustainable buildings performing as expected? And, how can building performance be comprehensively measured? This research investigates sustainable building performance and demonstrates a new methodology for evaluating buildings using the House of Quality matrix to structure the data. The matrix synthesizes data from building operations (including occupant satisfaction, operator satisfaction and actual building performance) to evaluate with respect to the original design intent. Two recent projects provide empirical data collected through an embedded research program. Rigorous data collection procedures were developed to provide information describing building performance. Occupant data was collected using a survey instrument and sampling techniques based on social science research methods. Data collection from building operators was based on triangulation, collecting data through interviews of different operator groups and through the environmental management and control system of each building. Project data was collected through field and embedded research programs and was based primarily on project documents and focused interviews of project team members. Upon completion of the three point evaluation, building performance is described on many levels using the House of Quality to structure the data. Performance metrics, based on the original design intent of the building, are rated by the user groups to enable cross comparison. The House of Quality speeds the process of analyzing the performance data to identify the crucial performance aspects for all stakeholder groups. This is a significant advance from existing research and evaluation practices. By quickly identifying critical building areas, resources are leveraged to investigate building systems of highest importance. The results of this research demonstrate the importance of the project team’s focus on the customer during project delivery—the owner organization, as well as significant end-user groups. In each of the two applications of the methodology, the research highlights the tensions that exist between the end-users and the project managers in organizations. The two applications of the building evaluation methodology also show that sustainable buildings do not necessarily perform better than their non-sustainable counterparts. This methodology provides feedback that is crucial to building owners and project teams as sustainable design and construction strategies continue to penetrate the construction industry. The results also indicate that project teams must continue to adapt project controls to establish owner values early in the project and focus design solutions towards these values. For their part, building owners must coordinate user groups to define their multi-layered definition of value and supply timely information to the project team for effective decision making in design.

This report evaluates the outcomes of World Bank Group support to Afghanistan from 2002-11. Despite extremely difficult security conditions, which deteriorated markedly after 2006, the World Bank Group has commendably established and sustained a large program of support to the country. The key messages of the evaluation are:•While World Bank Group strategy has been highly relevant to Afghanistan’s situation,beginning in 2006 the strategies could have gone further in adapting ongoingprograms to evolving opportunities and needs, and in programming activities sufficientto achieve the objectives of the pillars in those strategies.•Overall, Bank Group assistance has achieved substantial progress toward most ofits major objectives, although risks to development outcomes remain high. Impressive results have been achieved in public financial management, public health,telecommunications, and community development; substantial outputs have alsobeen achieved in primary education, rural roads, irrigation, and microfinance—allstarted during the initial phase. Bank assistance has been critical in developingthe mining sector as a potential engine of growth. However, progress has beenlimited in civil service reform, agriculture, urban development, and private sectordevelopment.•The Bank Group’s direct financial assistance has been augmented effectively byanalytic and advisory activities and donor coordination through the AfghanistanReconstruction Trust Fund. Knowledge services have been an important part ofBank Group support and have demonstrated the value of strategic analytical work,even in areas where the Bank Group may opt out of direct project financing.•With the expected reduction of the international presence in 2014, sustainabilityof development gains remains a major risk because of capacity constraints andinadequate human resources planning on the civilian side.To enhance program effectiveness, the evaluation recommends that the Bank Group help the government develop a comprehensive, long-term human resources strategy for the civilian sectors; focus on strategic analytical work in sectors that are high priorities for the government; assist in the development of local government institutions and, in the interim, support the development of a viable system for servicedelivery at subnational levels; assist in transforming the National Solidarity Program into a more sustainable financial and institutional model to consolidate its gains; help strengthen the regulatory environment for private sector investment; and scale up IFC and MIGA support to the private sector.Chapter AbstractsChapter 1This chapter examines the country context, including continuing conflict and insecurity, poverty, and the role of development partners and non-state actors (civil society and humanitarian organizations) in Afghanistan.

With the acceleration of urbanization and industrialization, carbon neutrality and peak carbon dioxide emissions have become common sustainability goals worldwide. However, there are few literature statistics and econometric analyses targeting carbon neutrality and peak carbon dioxide emissions, especially the publication trends, geographic distribution, citation literature, and research hotspots. To conduct an in-depth analysis of existing research fields and future perspectives in this research area, 1615 publications from the Web of Science Core Collection, between 2010 and 2020, were evaluated by using three analysis tools, under the framework of the bibliometrics method. These publications are distributed between the start-up (2010–2015) and the stable development (2016–2020) phases. Cluster analysis suggests three areas of ongoing research: energy-related carbon emissions, methane emissions, and energy biomass. Overall, future trends in this field include cumulative carbon emissions, the residential building sector, methane emission measurement, nitrogen fertilization, land degradation neutrality, and sciamachy satellite methane measurement. Finally, this paper further examines the most comprehensive coverage of nitrogen fertilization and the most recent research of the residential building sector. In view of the statistical clusters from 1615 publications, this paper provides new insights and perspectives for climate-environment-related researchers and policymakers. Specifically, countries could apply nitrogen fertilizer to crops according to the conditions of different regions. Additionally, experiences from developed countries could be learned from, including optimizing the energy supply structure of buildings and increasing the use of clean energy to reduce CO 2 emissions from buildings.

For decades, non-renewable resources have been the basis of worldwide economic development. The extraction rate of natural resources has increased by 113% since 1990, which has led to overexploitation and generation of vast amounts of waste. For this reason, it is essential that a sustainable development model is adopted—one which makes it possible to produce more food and energy with fewer fossil fuels, low pollutant gas emissions and minimal solid waste. Certain management policies and approaches, such as the strategy of a circular ecocomy or bioeconomy, are oriented towards sustainable production and consumption. The present study focuses on the importance of intensive horticulture in the Mediterranean region, specifically in the province of Almería (Spain). After having conducted a study of the main crops in this area, it was determined that the waste biomass generated presented strong potential for exploitation. With the proper regulatory framework, which promotes and prioritises the circularity of agricultural waste, there are several opportunities for improving the current waste management model. In the same way, the results of the economic evaluation demonstrate that the alternative of self-management of waste biomass is profitable, specifically from tomato crops. Compost and green fertilizer production also prove to be a key strategy in the transition towards a more circular and sustainable agricultural production model. As for the said transition, government support is vital in terms of carrying out awareness campaigns and training activities and providing financing for Research and Development (R&D).

Background Energy-efficient university campuses will play a vital role in the development of future sustainable cities, and will be important for achieving the Chinese carbon-neutrality goals. It is, therefore, necessary to develop new decision-making tools for evaluating the sustainability of campus buildings. Since university campuses typically comprise a broad variety of building types, standardized evaluation methods and tools, such as Green BIM, are needed. Green BIM (Building Information Modeling) emphasizes the importance and role of BIM technology in the design and construction of green buildings, providing a standardized framework for the decision-making process, and methods for improving the green performance of buildings. Methods This study develops a method based on the Green BIM framework, using BIM architecture to analyse building performance, and the Assessment Standard for Green Building (GB/T 50378-2019) standard to establish benchmark values for evaluation, and project objectives. The method is evaluated on three examples of the most representative university buildings in northern China. The goal is to understand common denominators and differences between different types of campus buildings, in terms of green building indicators, that are important to consider in the early design stages of campus building complexes. Results In this study, a library is used as a case study to demonstrate the tools for evaluating green performance. The study optimizes green performance from five aspects: surrounding environment, function layout, envelope performance and system transformation, and management measures improvement. The results show that this optimization scheme can achieve reductions of the annual loads of about 47.4%, in line with the national energy efficiency standards for public buildings. In particular, the heating load was reduced by 59.1%, and the cooling load reduced by 21.5%. Conclusion A comprehensive approach, combining the aspects of planning, building design, system design, energy management, and energy conservation planning, is required to improve the green performance of university buildings to meet the goals. In the future, it will be further necessary to perform data mining of energy consumption patterns, and continue energy retrofitting of existing buildings and energy systems, to achieve the goal of green and low-carbon campuses.

With ecological problems and energy crises intensifying today, greening is essential to sustainable development. Compared with other types of buildings, hospital buildings account for a relatively larger proportion of building energy consumption. In order to realize the rapid cycle optimization of a green hospital project in the design stage and improve the green grade of the building, a pre-evaluation Building Information Model (BIM) of green hospital building performance was established in this study. Firstly, the literature review and expert consultation established the building performance pre-evaluation index system for green hospitals. Then, BIM technology is taken to extract data needed for building a performance pre-evaluation system, and the Cloud Model and the Matter–Element Extension Theory are used to build models. The final green grade calculation is realized in MATLAB. Finally, the Maluan Bay Hospital is taken as an example to test the applicability and effectiveness of the proposed model. The results show that the green hospital building performance pre-evaluation model has advantages of simulation, cyclic optimization and fuzzy quantification, which can effectively guide the design and construction of a green hospital.

In recent years, the performance of the construction industry has highlighted the increased need for better resource efficiency, improved productivity, less waste, and increased value through sustainable construction practices. The core concept of sustainable construction is to maximize value and minimize harm by achieving a balance between social, economic, technical, and environmental aspects, commonly known as the pillars of sustainability. The decision regarding which structural material to select for any construction project is traditionally made based on technical and economic considerations with little or no attention paid to social and environmental aspects. Furthermore, the majority of the available literature on the subject considered three sustainability pillars (i.e., environmental, social, and economic), ignoring the influence of technical aspects for overall sustainability assessment. Industry experts have also noted an unfulfilled need for a multi-criteria decision-making (MCDM) technique that can integrate all stakeholders’ (project owner, designer, and constructor) opinions into the selection process. Hence, this research developed a decision support system (DSS) involving MCDM techniques to aid in selecting the most sustainable structural material, considering the four pillars of sustainability in the integrated project delivery (IPD) framework. A hybrid MCDM method combining AHP, TOPSIS, and VIKOR in a fuzzy environment was used to develop the DSS. A hypothetical eight-story building was considered for a case study to validate the developed DSS. The result shows that user preferences highly govern the final ranking of the alternative options of structural materials. Timber was chosen as the most sustainable option once the stakeholders assigned balanced importance to all factors of sustainable construction practices. The developed DSS was designed to be generic, can be used by any group of industry practitioners, and is expected to enhance objectivity and consistency of the decision-making process as a step towards achieving sustainable construction.

The article briefly discusses the content and terms of construction project management. It identifies the main problems of construction management and discusses ways to solve those using multi-criteria methods. Well-performed management is one of the critical factors which leads to the success of any significant sustainable project. Construction project management consists of setting goals and defining user requirements, project constraints, and resources needed. This paper aims to create a practically useful model. The paper presents a comprehensive set of criteria, which led to the creation of a decision-making model for construction management, which was applied to a Turkish case study. The Analytic Hierarchy Process (AHP) method and the Expert Choice computer program were used for calculations.

The building sector accounts for 38% of carbon emissions, the principal cause of climate change. To meet the targets set by the Paris Agreement, including zero net emissions by 2050, it is necessary that governments develop a culture of sustainability. Whole Life Carbon Assessment of a building, comprehensive of operational and embodied carbon (EC), is described by EN15978:2011. Net Zero Carbon Buildings (NZCB) achieve a balance of zero emissions during their life cycle, promoting both reduction and compensation by adopting many strategies (e.g., reuse of existing structures, design for adaptability and disassembly, circular economy principles). Choosing bio-based materials is also helpful to compensate for EC, thanks to the biogenic carbon stored during their growth. The aim of this research is to find out which strategies are relevant to meet NZCB target, in order to apply them to a case study of reuse of an abandoned building in Milan, highlighting the design process. Material quantities were extracted from the BIM model and imported in OneClick LCA to assess embodied carbon emissions (A1–A5 modules, material production and supply, transport, construction). The final design stage achieved a reduction of 91% in EC compared to a standard new construction, while the bio-based materials compensated for the rest. Further research can improve the Environmental Product Declaration (EPD) of materials and assess the entire building life cycle.

PurposeThe purpose of this paper is to identify the key facilitating factors for smart sustainable practices (SSP) and develop a project evaluation model (PEM) for SSP implementation in Nigeria and Hong Kong. SSP is coined from the integration of digital technologies such as Building Information Modelling (BIM) to facilitate sustainability practices.Design/methodology/approachThe study employed a quantitative research design approach using empirical questionnaire surveys to solicit the opinions of 69 and 97 construction practitioners in Nigeria and Hong Kong. Purposive and snowball sampling techniques were used to identify the potential survey respondents. The fuzzy synthetic evaluation technique was used to develop the PEMs.FindingsThe findings revealed that adequate technical expertise of the SSP processes is critical in enhancing its implementation in Hong Kong and Nigeria; as well as the provision of training programs for specialists in smart and sustainable initiatives. Meanwhile, the study's findings advocated that for an SSP-enabled construction project, its project performance is mainly influenced by the client's satisfaction level and the early involvement of the project teams.Research limitations/implicationsThe study's results are limited to the Nigeria and Hong Kong construction industries.Practical implicationsConstruction stakeholders such as the clients, developers, contractors can utilize the PEMs to determine and track SSP initiatives implementation in building projects in a reliable and practical way.Originality/valueNo tool has been developed for evaluating SSP initiatives at the project level in the construction industry. Using case studies of Hong Kong and Nigeria, PEM indices were developed to measure and track SSP implementation in construction projects.
