Studies related to social sustainability assessment have presented a variety of methods and criteria, but there is a need to better understand how these studies incorporate multiple criteria along with the issues addressed, the decision-makers, and the overall process followed to promote more socially sustainable outcomes. A systematic literature review methodology is conducted to identify, analyze, and synthesize scholarly articles that use multiple criteria to assess the built environment's social sustainability. This study explores types of problems, decision-makers, criteria, and methods adopted by researchers. The analysis involved 42 studies identified in the Web of Science, ScienceDirect, and Scopus databases. The results revealed a diverse range of studies, covering various issues, project types, and methodologies, highlighting the multifaceted nature of social sustainability evaluation in the context of the built environment. The most considered social sustainability issues in the studies were 'Impacts in Community' and 'Employment'. While most of the selected papers used multi-criteria decision-making/aiding (MCDM/A), not all engaged in these methods for decision-making purposes. Moreover, despite the prevalence of studies involving multiple decision-makers, issues related to group decision-making were often insufficiently addressed. The types of problems that the methods are used for are discussed, as well as the decision context and the process for selecting methods, thereby highlighting future research opportunities. Future studies should ensure that the criteria used are manageable but encompass all facets of social sustainability in the built environment, prioritizing methodological rigor when selecting MCDM/A methods and focusing on the nuances of preference aggregation in group decision-making scenarios.

This study presents an analysis of the potential uses of BIM for managing the maintenance and refurbishment of existing housing assets to propose thermal comfort and energy efficiency guidelines for future social housing projects in Brazil. To do so, a case study analysis of a residential development with social–environmental certification in the city of Garanhuns, Pernambuco, Brazil was performed, and a literature review on the use of BIM for residential unit maintenance was conducted. The standard house in the residential development was found to be noncompliant with the Brazilian standard for ventilation openings (NBR 15.220). Therefore, three alternative layouts were created and analyzed to meet the requirements of the standard as well as the needs of the residents. The authors recommend that socio-environmental certifiers use BIM models so that energy performance and other simulations can be carried out. The study also proposes guidelines for BIM implementation in future government housing projects. These guidelines were grouped into five categories: BIM encouragement, energy efficiency, maintenance management, user requirement management, and continuous improvement. The significance of this study is in providing a path for the gradual implementation of BIM for maintenance and post-occupancy management in the Brazilian housing program. [ABSTRACT FROM AUTHOR]

This study aims to assess the applicability and adherence to social sustainability indicators by large and medium-sized construction companies in Pernambuco, Brazil. The study measures the importance and influence of these indicators in companies' decision-making processes. The social indicators from the Global Reporting Initiative (GRI) were selected as they come from a globally recognized and widespread organization. The research focuses on nine companies by conducting semi-structured interviews, site visits, and data validation through observations. The results indicate that most of the indicators were considered to have a high level of importance. However, these indicators are not as influential in decision-making as their importance suggests they should be. Currently, only 26% of the indicators are being measured by the companies, covering only three of the 19 GRI categories. The categories reported are occupational safety and health, local communities, and customer privacy. Most companies would be able to report the other 16 categories with minimal additional effort. A prioritization matrix is presented according to the importance and influence of the indicators and the effort to implement them. Overall, this study reveals that companies could easily measure most social sustainability indicators, making it possible to implement more sustainable decisions with less effort.
