Software calculation tool for light savings in the buildings compared with real measured data
Original language description
This paper describes modeling of possible savings in lighting systems of artificial lighting, working in combination with daylight. The proposed model works with overcast sky daylight (CIE). Based on knowledge of geographical position, day and time, thecalculations are done in the conditions of unshadowed outdoor illuminance levels. From this figure (when daylight factor is known) illuminance caused by daylight can be gain in the different parts of the room. By controlling the artificial lighting (dimming) to constant cumulative value (daylight plus artificial light) in the areas of visual tasks, then it is possible to determine potential of savings in areas with controlled lighting system and without it. According to this model (calculation), we canconsider a suitability of the dimmable lighting systems in the specific work areas and make recommendations to reduce energy requirements of buildings in energy audits. The sample model was compared with measurement of illuminance in the
