EFEITOS DAS VARANDAS NO DESEMPENHO TÉRMICO, ENERGÉTICO E LUMINOSO DE EDIFICAÇÕES

REVISÃO SISTEMÁTICA DA LITERATURA

Abstract

Shading and natural ventilation are effective passive strategies to assure thermal comfort in most part of the Brazilian territory. Balconies can be used as a solar shading device that behave as an eave to the lower floor, reducing the incidence of direct solar radiation, while allowing reflected and diffuse daylight and natural ventilation through windows openings. A systematic literature review was conducted aiming to present the state of the art about the effect of balconies on thermal, energy and daylight performance of buildings and identify trends and gaps in this subject. The systematic review indicated an increase in the number of publications in the last five years, showing, as a main focus, the analysis of the effect of balconies on the thermal performance of residential buildings, through computational simulations. This study shows the complexity in crossing the results obtained for thermal, daylight and energy performance in buildings provided with balconies, showing the interdependence of the independent variables and, often, negative relation between them. As future work, we identify the need of studies specifically for the office typology and to develop design guidelines for the early design stages, so balconies can behave to their full potential in providing thermal, daylight and energy performance concurrently.
