Abstract: This paper presents a computer application which applies methods for detailed daylighting and electric lighting numerical simulation, allowing interior illumination levels assessment. For the natural light, vertical windows are considered. For the artificial light, illumination levels can be calculated for a great variety of commercial fixtures, considering their luminous distribution curves. The performance of the integrated design is calculated in an hourly basis and represents the achieved energy savings if automatic (sensor-based) electric light control is used. All the calculations can be carried out in a very fast way, allowing the optimization of the electric light system and helping lighting designers in the adoption of such calculations in their everyday practice. The application interfaces and program utilization are presented.
