Housing indicators for sustainable cities in middle-income countries through the residential urban environment recognized using single-family housing rating systems

This study presents a comparative analysis of the housing indicators used by the single-family housing rating systems (SHRSs), in which the residential urban environment (RUE) influences buildings’ certification scores, emphasizing the relationships of six systems developed by middle-income countries (MICs)—BEST, CASA, GBI, BERDE, Green Homes, and LOTUS—and the two most-recognized rating systems, BREEAM and LEED. The aim is to provide new housing indicators that are capable of bringing the concept of sustainability into the cities of MICs. The results reveal that the percentage of influence that single-family housing (SFH) can achieve in the metric established by each system is relatively low. However, considering all of the identified indicators, this influence could increase to 53.16% of the total score in multi-criteria evaluations. Furthermore, a significant lack of indicators for mandatory criteria evaluations was found, with CASA being the only system that considers their inclusion. This paper identifies 37 indicators for multi-criteria assessments and two for mandatory-criteria assessments, providing new perspectives on several topics. Furthermore, the methodology established to obtain the indicators could be useful for other researchers in the identification of new sustainable indicators.
