AMPLITUDES TÉRMICAS DIÁRIAS NO ESTADO DO PARANÁ

SUBSÍDIO PARA PROJETO DE EDIFICAÇÕES

Abstract

Buildings must fulfill the function of a shelter with low environmental impact. Among the parameters for efficient building projects are adaptive thermal comfort models, which impose limits on the daily thermal amplitudes in indoor environments. In order to respect such limits in a given climate, it is necessary to know the daily thermal amplitudes of the external environment in order to define measures to control internal temperature fluctuations. Techniques are used such as: walls with high thermal capacity, resistive insulation on the external faces of the envelope, shapes with high compactness, among others. However, in Brazil, maps of specific daily thermal amplitudes for civil construction are not available. This research aimed to map the daily thermal amplitudes in the state of Paraná in order to produce subsidies for housing projects with low energy consumption. Data from meteorological stations in 49 municipalities were used. The maps produced allow designers, from the coordinates of localities in the state, to obtain daily thermal amplitudes of reference for the project in the 99, 97.5 and 95 percentiles.
