Evaluación del confort térmico en recintos de 10 edificios públicos de Chile en invierno

Abstract

Environmental comfort in working space is an essential component in any architectural project and takes more strength every day, but little is known about. Environmental variables were measured and surveyed satisfaction of 10 public buildings in use throughout Chile obtaining the predicted percentage of dissatisfied (PPI), predicted mean vote (PMV), Percentage of Dissatisfied (PI) and mean vote (MV). We compare the neutral conditions contained in the standards ISO 7730 and ASHRAE 55, and the calculated indices. Also discusses the satisfaction surveys and possible adaptation factors. The results showed low level of environmental acceptability in 4 schools mainly because of poor air quality and low temperatures, correlating positively with the surveys and the difference between operational and effective temperature, which reaches -10.05 °C. In 80% of the buildings prefer warmer environments in winter, moving the neutral +0.52 points on the scale of thermal sensation. It is hoped that such investigations will go in rise given the countrys real need to have comfortable venues that improve productivity and user acceptance for their work environment.
