Abstract
This paper presents a computational application that allows choosing membranes and sizing them for tensioned structures in order to provide thermal and luminous comfort. The membrane thermo-luminous characteristics database was developed through field researches and lab researches using spectrophotometer. The computational modeling consists of: thermo-physiological balance, radiation model, calculation of sky temperature, calculation of surface temperatures of ground, vegetation and membrane. The Heat Load index was adopted for assessing thermal comfort. Concerning luminous comfort, membrane transmission and the contribution of the uncovered sky were considered. The final result is a computational application, with data of 27 different kinds of membranes and climatic data of 57 Brazilian cities, which assesses the thermal and luminous comfort of a given environment, considering: dimensions, activities, membrane, surrounding characteristics and city. The assessment is done hourly for a typical day of each month of the year. Software validation was done through positive comparisons with results of empirical data gathered in field researches.
