%X the technical quality regulation on the energy efficiency of commercial, service and public buildings (rtq-c) is the brazilian reference for evaluating the energy performance of buildings. this study focuses on the influence of solar protection devices in building consumption based on this code. a building without solar devices is analysed under the prescriptive method of rtq-c. overhangs and lightshelves are designed for the building and the performance under rtq-c is recalculated. then, the same devices are applied to a room in the building. the total energy consumption of the room with and without solar devices is obtained through computer simulation. the results of this process are the basis for a discussion about the performance evaluation criterion of the prescriptive method of rtq-c. the main results reinforce that the geometry and solar orientation of a device must be considered, although the prescriptive rtq-c does not consider those aspects.
