Purpose: The aims of this paper is to establish an appropriate physical-change-based renewal (PCBR) projects selection mechanism capable of selecting the combination of the PCBR projects that can make up an integrated urban renewal program in high-density cities. Design/methodology/approach: The research design follows a sequential integrated methodology that combines the calculation algorithms of Fuzzy Analytic Network Process (Fuzzy-ANP) with Zero-One Goal Programming (ZOGP) to support decisions for the selection of PCBR projects. In the first phase, general criteria for assessing the sustainability performance of PCBR projects were collected from relevant literature. In the second phase, the Fuzzy-ANP was used to identify the priority weights of the candidate projects through clarifying the interdependent degree between the criteria and candidate projects. Finally, ZOGP method was selected as a predetermined number of PCBR projects among candidate projects. Findings: The feasibility and effectiveness of this hybrid approach is then verified in a case study of Yuzhong District, Chongqing in China. The results of this study indicate that the integrated method is capable of directing the decision maker toward the best compromising solution of PCBR program that can achieve the maximization of sustainable benefits and allocate limited resources most efficiently. Originality/value: The novelty of this paper consists in combining the algorithms of the Fuzzy-ANP method with those of the ZOGP model that serves as an effective analysis tool to address practical decision problems. This is the first hybrid algorithms to make PCBR projects selection decision that reach the maximization of the sustainable benefits, both in economic and socio-environmental terms.

The research works to highlight the importance of sustainability and its role in raising the efficiency of commercial centers and upgrading them to achieve optimal performance in terms of environmental, functional, economic and construction terms to achieve the desired goals and help in attracting the largest number of users and achieving the largest possible percentage of profits, as commercial buildings are an important element of attraction Which, in turn, is reflected in contributing to raising the national economy, by explaining the concepts related to sustainability, starting from identifying sustainable development strategies, leading to sustainability in the commercial environment, to extract the standards that must be met in commercial buildings to achieve sustainability, a case study of the Guangzhou Taiko Building in China and analyzed through sustainability criteria.

The sustainable construction and operation of large stadiums has been widely recognized as an important goal. Existing building sustainability evaluation criteria mainly focused on the energy-saving dimension. However, more dimensions (such as economy, intelligence level, conversion difficulty, etc.) that are quite important for multifunctional buildings' sustainable operation have earned only limited attention. This research aimed to develop a sustainability evaluation system that integrates multidimensional parameters by taking Chinese stadiums as a precursor to influence the assessment criteria for the sustainable operation of local multifunctional buildings. Based on an extensive review of sustainable building assessment methods in the published literature and expert interviews, this research constructed a stadium sustainability performance database as an initial pool of criteria to comprehensively reflect the environmental, social, and economic attributes of stadiums. The indicators and data gathered were evaluated through regression analysis and principal component analysis (PCA) to clarify the impact and weight of indicators in the evaluation system. In addition, the study developed an online visual evaluation platform based on the evaluation system combined with Building Information Modeling (BIM) to assist architects to complete the performance evaluation of the stadium and the prediction of future design. 3 cases of different types of stadiums in China were evaluated to demonstrate the platform interface. The findings of current research will help architects, administrators, and researchers accomplish sustainability in the design, management, and operation of stadiums. [ABSTRACT FROM AUTHOR]

Sustainability assessments are an increasingly common tool for measuring progress towards sustainable development. Despite their popularity, sustainability assessments and the indicators that compose them are said to have had little impact on the policy arena. In this paper we discuss four attributes that we contend will improve the use of sustainability assessments to guide decision making: non-compartmentalization, site specificity, built-in guidance for target setting, and ability to measure active sustainability. We present a novel assessment tool for wastewater treatment infrastructure that illustrates these attributes. The assessment is composed of two-dimensional indicators we call “burden to capacity” ratios, that reveal and quantify the local value of resources embodied in wastewater and treatment byproducts, and the tradeoffs between designing systems for disposal versus reuse. We apply the sustainability assessment framework to an existing treatment plant in Chengdu, China and discuss the results. [Copyright &y& Elsevier]
