Description
The use of daylight is indicated as a primary factor in energy savings of buildings, since it can reduce the use of electric lighting through control systems. However, the efficiency of systems is also associated with technical characteristics and performance of various elements. The positioning of fixtures, as well as its specifications can contribute for environmental comfort and energy conservation. Such concerns, however, are not part of the currently established practice of lighting design professionals. Considering this gap, this paper seeks to develop a study that addresses the integration of natural and electric light. The methodology is based on evaluating the performance of light, such as distribution of illuminance and estimated energy consumption of lighting systems through computer simulation. It’s estimated daylight availability for a open plan office, located in Florianópolis / SC. Analyses of daylight are used to measure the energy consumption for different proposals for lighting systems, by dividing the drive circuits. The systems are differentiated by photometry and disposal of the fixtures. The results show significant differences in light distribution, as well as in energy consumption, reaching average values of 32% savings. One of the major goals of this study is to obtain criteria that lead to a better design of the electric lighting system as well as generating knowledge about the design process.
