According to the decree 1285 (1), regulating the approaches of sustainable construction in Colombia as part of the inclusion of "Environmental Criteria for the Design and Construction of Urban Housing" of the Ministry of Environment and Sustainable Development, the following research work is part of the management of passive measures for the improvement of the thermal condition of housing buildings.
Under this approach, the analysis of envelopes (walls and roofing) is key to enriching the proposals for improving thermal comfort focused on light dry construction systems and their components. In the case of walls, described and expanded in the text "Analysis and Evaluation of thermal performance of the Light Dry Construction System in Residential Buildings” (2), factors that trigger heating inside the spaces due to heat transfer phenomena are detected. In this section we isolate the roof variable that is addressed in the current project, called "Analysis and evaluation of the thermal performance of roofing systems used in dry constructions for Residential buildings located in the city of Santiago de Cali and its area of influence", where different roofing solutions are tested in the field considering this variable as fundamental in the analysis, thermal comparison and evaluation, not including architectural management variables that can be simulated later (openings of gaps in specimens and arrangement of spaces).
At the same time, they considered technical aspects that were successful in the previous study, being that they determined the behavior of the components of the construction system and their location; These mechanisms include ventilated chamber and well-performing thermal insulation such as glass wool and polyester foam
