Double façades and thermal performance

a systematic review

Abstract

The double facade system, characterized by the addition of a second skin to the building envelope, maintaining an intermediate air chamber, is presented, in several studies, as an effective solution for reducing the heating of buildings. The objective of this research was to systematically analyze scientific articles on energy efficiency in double facades, categorizing them according to construction typology, location and chronology of publications, with the intention of observing existing gaps that can be addressed in future research. The research method provides for the definition of a search syntax for the databases, eliminating duplicate articles and those outside the proposed topic and organizing the results in tables and graphs. The main results show the topic to be of recent interest in the international scientific community, with few studies published on double facades with opaque materials and few studies carried out in countries with a tropical climate, such as Brazil.
