A disponibilidade de luz na residência: análise do desempenho de luz natural e a influência do layout de interiores em habitações do PMCMV

Abstract

The Minha Casa, Minha Vida (PMCMV) program, as well as other policies aimed at social housing in Brazil, do not present adequate solutions regarding the luminous comfort inside the residences, nor do they express the relevance of a furniture layout that favors an adequate distribution of daylighting for the environments. Thus, the objective of this work is to evaluate the influence of furniture on the performance of natural lighting in housing units of the Residential Condominium Jardim Tropical, in Maceió. An evaluation of the luminous performance of the housing unit was carried out with the insertion of furniture in the living/dining room environment. In addition, the results of the models with variations in furniture and material were compared. The TropLux 8 software was used as a tool for computational simulation and the metrics Mean Annual Illuminance Variation (∆EMA), Mean Annual Uniformity Variation (∆UMA) and Simplified Probability of Daylight Glare (POLNs/DGPs) were adopted. It is considered the work plan of the living/dining room; the period corresponds to the interval from 7:30 am to 4:30 pm for all days of the year; and the orientations and south­southeast and north­northwest, according to the implementation adopted in the place. The results indicate that the insertion of furniture, compared to the environment without bulkheads, does not cause significant changes in the level and distribution of illuminance, being the factor that most interferes with the materiality in the furniture. Based on the analyzes carried out, it was also verified that in situations in which the individual is in work planes facing windows/doors with natural light, the probability of glare is greater, compared to the use of the user in a position perpendicular to the incoming light. Such results form a knowledge base relevant to the proposition of parameters that contribute to the guarantee of a good performance of daylighting in future projects of ambiance in housing of social interest.
