GIRALDO-CASTANEDA, Walter; CZAJKOWSKI, Jorge Daniel  and  GOMEZ, Analía Fernanda. Thermal comfort in multi-family social housing in a warm climate in Colombia. Rev. Arquit. (Bogotá) [online]. 2021, vol.23, n.1, pp.115-124.  Epub July 15, 2021. ISSN 1657-0308.  https://doi.org/10.14718/revarq.2021.2938.

Residential energy consumption in Colombia increased by 30% between 2010 and 2018, due, in part, to spending on active air conditioning of social interest housing (VIS). Research on single-family VIS reported "very hot" thermal sensations with the PMV-PPD model in hot weather. The objective of the present research is to complement the state of the art by evaluating the thermal environment of a multifamily SIV with two different comfort models: 1) the PMV-PPD and 2) the adaptive model. The methodology had two phases: 1) monitoring of a VIS environment, and 2) assessment using the two models mentioned above. The results indicated thermal dissatisfaction due to excess heat with both models during daytime hours, very similar to what has been reported in the state of the art for single-family typology. However, a 35% saving in energy dedicated to air conditioning was also found if evaluated with the adaptive model. The absence of solar protection in openings was evidenced, and the high values of air temperature and mean radiant temperature indicated that the thermal insulation of the vertical envelope of these buildings is insufficient to provide thermal comfort. Passive improvements are proposed to ameliorate the habitability of these dwellings and their mandatory inclusion in Regulation 0549, to reduce energy consumption and its environmental impact.
