Social housing in Colombia presents a problem associated with the selection and use of materials that are consistent with climate change and the conditions of thermal and lighting comfort. This research evaluates different options to suggest a bet ter selection of building envelope materials; for this, an urban housing prototype located in the Bella Vista district of Soacha (Colombia) was used. The modeling used three groups of materials categorized as traditional, avant-garde, and innovative. 144 thermal and 18 lighting simulations were carried out, considering the climate and its variations during the next fifty-five years of useful life of the building, in order to compare and identify the combination of materials that achieve better thermal and lighting efficiency. As a result, the paper found that traditional and innovative materials have greater efficiency, although they require passive design actions since they are outside the comfort ranges. Avant-garde materials showed balanced values within the two categories.

Keywords : Adaptation to climate; bioclimatic architecture; thermal behavior; thermal and lighting comfort; construction materials; simulation model.
