The increase in energy consumption in the world contributes to a greater environmental impact and one of the ways to provide the reduction of this impact is through bioclimatic architecture. The objective of the research was evaluate the use of passive strategies in the University Restaurant building at the campus UFES Alegre-ES, with emphasis on thermal comfort. The strategy used was the chimney effect, considering the conditions of hot and humid weather. The method used was divided into three stages: Definition of constructive solutions for comparative analysis: conventional, with side openings and the combined use with clerestory - chimney effect; Characterization of the model, material properties, and the period of the simulation with the software Design Builder; and Simulations with the methodology proposed by Nico-Rodrigues (2015) for the evaluation of the thermal performance of naturally ventilated environment, with emphasis on thermal comfort, using the indicators FDT (Thermal Discomfort Frequency) and GhDT (Degrees hours of thermal discomfort). The results obtained for all summer months show a higher efficiency in the environment that was simulated using the clerestory, resulting lower temperatures, unlikely the model without clerestory where there were longer periods of frequent and severe discomfort. Considering the need to use passive strategies, this study allowed the choice of the technical solution with the best cost / benefit for obtaining the thermal comfort. | Ricardo N.
