Abstract

This research has resulted in the proposition of a group of directives which may enable the implementation and outlining of an energetic regulation project for office buildings as related to daylighting. To that end, current codes, norms and certification systems, in use in Brazil, United States, Canada, Portugal, United Kingdom, France, and Germany, all regarding daylighting and its interaction with artificial lighting in office buildings, were raised. We have added to this group of regulations the ISO and CIE norms, due to their being international references. Starting out from these regulations, the items that contain indicators for the evaluation of daylight admission in office buildings have been grouped and outlined by category. In chapter 5, Case Studies, five office buildings in Sao Paulo city have been analyzed regarding their insolation and daylight performance. The projects were computer-simulated and, through the results obtained by applying the Radiance software, the conformity of these projects with the collected indicators were verified. These evaluations led to conclusions about the projects, as well as about the used indicators. From these conclusions, directives have been presented for use in the Brazilian case, identifying items for regulations that, when applied, will optimize the use of daylight in offices. (AU)
