The Thermal Influence of Envelopment in Naturally Ventilated Environments

Motivated by the increase of 42% on average in Brazilian demand for electricity in the period 2003-2013, due to population growth of 12.3% since the year 2000, it has become a priority the adoption of improvements in construction, seeking thermal efficiency. More efficient buildings have as targets the intervention and identification of solutions on the project stage, as the choice of materials with different thermal characteristics performance. The study aimed to analyze the influence of envelopment for the thermal performance of university building in a tropical and humid climate, and the use of natural ventilation as a strategy to improve the comfort, according parameters of Frequency Thermal Discomfort (FDT-%) and Degrees hours of Thermal Discomfort (GhDT-°C.h), seeking the least energy expenditure and promote buildings suitable for the environment. There were made three methodological steps with the 1st on the review of the key concepts work; the 2nd descriptive experimental research simulation with DesignBuilder software; and 3rd of results analysis. Among the results, it was observed that the analyzed environments are all uncomfortable especially the located on the upper floor, with an increase in rates of FDT and GhDT, pointing great interference in thermal gains the roof, intensified by the impossibility of heat exchange ventilation by night, due to the window models, so being required artificial conditioning and required specification of efficient materials. | Marlon - marlon.oliveira@ifes.edu.br
