Abstract: Nowadays, the employees spend around 8 to 10 hours a day in their offices , therefore, the creating of right work environment is an essential matter in today’s designs for offices. However , some people till today don’t know how could the lighting influences the workers at the offices . In this study , the researcher has explored the effects and impacts of one parameter which is the ‘surface reflectance’ in interior spaces as walls , ceiling and floor , on the illuminance level that is visible on the work plane by employees . For the purpose of proving it , two digital models were created in this study in order to run the simulations. Significantly, the small area office illuminance increased with high values when the wall surface reflectance is high . In the large open spaces , and when the ceiling surface reflectance is high , the illumination will be increased more than results of increasing wall reflectance values . In this study , the researcher addressed the effects of the wall reflectance through a variety of simulations for the reflectance’s of ceiling , walls and floor , to demonstrate the effects of the surface reflectance on increasing the space illumination , which can play a role as an energy saving as well as cost saving while the high demand of lighting is needed .
