Avaliação de conforto térmico eficiente em edificações de interesse social na zona bioclimática 2: simulação computacional do desempenho da envoltória

Abstract

The present work proposes a composition of strategies for a popular building project in the city of Alegrete-RS, located in the bioclimatic zone 2. Bioclimatic strategies of passive conditioning recommended by NBR 15220 (2005b) were developed for conditions of great climatic variation, seeking to optimize the thermal performance of the envelope in an efficient way. After the development of the project with the strategic constructive interventions, both were evaluated by computational simulation based on the RTQ-R (2010) parameters and definitions , through the Open Studio and EnergyPlus programs. For the analysis of the thermal performance of the projects, it was used as base the system degrees-hour of discomfort in relation to the internal operating temperature of the rooms of prolonged permanence. The results show an improvement in the cold periods of the year, where it was possible to verify in the environments an increase of time within the comfort range, between temperatures of 20 to 26ºC, as well as a decrease of thermal amplitude within these environments, increasing the sensation of thermal comfort to users.
