DETERMINAÇÃO DA TEMPERATURA DE NEUTRALIDADE EM EDIFICAÇÕES PÚBLICAS, COMERCIAIS E DE SERVIÇO NAS ZONAS BIOCLIMÁTICAS 5 E 6 DO ESTADO DE MATO GROSSO

Abstract

Thermal neutrality represents the condition in which a person in a given environment does not feel heat or cold, being in thermal balance. This is a conditioning factor for achieving thermal comfort. There are not known zones of comfort and neutrality temperatures in the State of Mato Grosso, contributing to the low thermal performance of buildings. This study aimed to determine the neutral temperature of public, commercial and services buildings, for the 5 and 6 bioclimatic zones in the Mato Grosso state. It was applied the Spot-Monitoring concept, which relates the collection of environment data (by the usage of equipment with sensors) with a simultaneous appliance of questionnaires that collects sensations and thermal preferences of the users. A total of 247 measurements were performed and 2223 questionnaires were applied to the cities of Sinop and Primavera do Leste. By utilizing linear least-squares regressions analysis that correlates the thermal sensation vote with the operative temperature, equations that determine the neutral temperature were obtained. For these buildings, in those cities, the neutrality temperature average was 24,6°C.
