CONSIDERAÇÕES SOBRE O DESEMPENHO TÉRMICO, LUMÍNICO E ACÚSTICO DE SISTEMAS CONSTRUTIVOS INOVADORES EM USO

Abstract

Industrialized self-supporting prefabricated building panels are part of the innovative construction system used in the social housing program Minha Casa Minha Vida (PMCMV). The panels represent an improvement in the conventional production process. Innovative technologies are approved under the Brazilian Technical Assessment System (SiNAT) and have technical assessment documentation certifying the performance of the product. However, laboratory tests have not covered the ‘behavior in use’ of the panels in social housing applications. The purpose of this article is to assess the thermal, lighting and acoustic performance in use of dwellings differentiated by the construction technology used: reinforced concrete panels molded in polyvinyl chloride (PVC) and a system of light panels structured in treated wood (Light Wood Frame). In this context, the Post-Occupancy Evaluation (POE) was adopted as a research strategy because it is a method that enables a technical assessment, as well as a complementary gauging of user perceptions. The results show the need to re-evaluate the criteria for thermal, lighting and acoustic performance for reapproval of the PVC-concrete system in future social housing applications. The thermal and acoustic performance of the light wood frame system was satisfactory, but in both cases the expansions impaired lighting performance.
