This research studies the implementation of technologies and guidelines for the large-scale retrofitting of representative urban housing. It evaluates the energy performance of a typical social housing dwelling with a high level of replicability. To this end, the potential energy savings resulting from the application of various building envelope improvement strategies in accordance with Argentine regulations are calculated. The technology and the thermal and energy behavior of a dwelling located in the “645 Dwellings” neighborhood (645 Viviendas) built by the Institute of Planning and Promotion of Housing (IPPV) in the city of San Carlos de Bariloche are described. This neighborhood presents a major energy emergency, since the houses are located in bio-environmental zone IV (very cold) and are not connected to the natural gas grid. Subsequently, the results of the 2016 energy audit are examined and a thermal simulation with Ecotect Analysis 2011 software incorporating the actual audited conditions of use is shown. After adjusting the model, 24 thermal envelope improvement strategies are analyzed in order to identify those with the greatest impact on energy demand reduction.
