Resumo
This work has as goal to study the resultant daylight from International Style buildings openings in São Paulo, in Avenida Paulista and Berrini axis, analyzing illuminance distribution. The approach was done from the solar geometry and glass types point of view. The use of daylight and natural ventilation in buildings has always been part of architects challenges, nevertheless with the beginning of energetic crises during the 1970s, these issues became more important. However the concern with energy saving and use of natural resources are not usually demonstrated in the finished building. As São Paulo has a subtropical climate, the biggest concern is to avoid buildings inner heat, and the typical solution is the use of solar control glasses to reduce costs with air conditioning. Nevertheless even high performance glasses block a substantial part of daylight, beyond the heat. The compensation for low interior luminousness is done by artificial means, increasing unnecessarily buildings use and maintenance costs. Buildings from São Paulo, Brazil, Berlin and Frankfurt, Germany, were studied with local measurement and with floor modeling in Relux Professional 2010. Daylight distribution characteristics of each building were identified with the purpose of delineating potential projects improvements, focusing São Paulo daylight availability throughout the year The analysis results showed that international style façades have limitations to increase the use of daylight since the whole shell has a single treatment. Both in German and Brazilian buildings the daylight distribution followed a trendline, indicating the need of using other means to obtain illuminance levels with fewer variations between room endings
