Calculation assumptions

The reflectivity of walls, ground and ceiling are respectively 0.75, 0.45 and 0.75.

The Lighting French Association recommands an illuminance level of 300 lux in a typical office

[4] . In this study, the value of acceptable illuminance level has been set to 300 lux. To quantify the mean daylight autonomy in the room, the room has been divided into three equal strips (see Figure 3). The illuminance level is supposed to be the worst in the middle strip. For this reason, we will focus on this specific zone.

3. Results and discussion

This section presents some preliminary results of the study to determine a combination between the solar shading and daylighting in buildings.
