INFLUÊNCIA DA COBERTURA E DA ORIENTAÇÃO NO DESEMPENHO TÉRMICO DE UMA CRECHE DO PROGRAMA PROINFÂNCIA EM CLIMA QUENTE E ÚMIDO

Abstract

Standard projects are often used in public works due to rationalization in construction. In the education´s area, the Proinfância Program stands out, which advocates standard projects of the Municipal Center for Early Childhood Education (CMEI) for Brazil. However, the thermal performance of these projects can be impaired, since issues such as project implementation can not be predicted against the possibility of implementation in different climatic contexts of the country. Thus, the article seeks to evaluate the influence of different orientations and coverage on the thermal performance of a CMEI type B of the Proinfância program in Maceió-AL. The development of this research involved: the definition of a computational model representative of the CMEI and simulation with EnergyPlus Program; surface heat gain analysis; simulations in eight implementation guidelines and tests with different coverage. The results indicated the highest heat gain from the coverage, reaching 180 W/m², from 7 am to 4 pm. It was observed that there was no significant variation in the thermal performance of the rooms when the guidelines varied, where all rooms presented annual percentages of discomfort of approximately 38% (600 ° ChR). The coverages evaluated resulted in reductions of approximately 50% in discomfort compared to the real model (dark coverage without insulation), with clear coverage being the most feasible. With the results it is possible to make adaptations in the project that potentialize the activities developed in the environments, and favor the learning process of the children through the achievement of thermal comfort.
