Abstract
Daylight utilization in office buildings for creating natural indoor working condition and saving lighting consumption was reported in this paper. An office model was developed for the simulation on the influence of glazing transmittance, sill height and Window-to-wall Area Ratio (WAR) on indoor illuminance distribution and lighting saving. The equations expressing the relationship between the illuminance and the affecting factors were presented. The simulation results indicated that the lighting saving was a quadratic function of glazing transmittance. The increase of sill height by 0.1m produced an increased lighting saving of 0.219 W/m 2 in sunny day as well as 0.225 W/m 2 in cloudy day. The increase of WAR by 0.1 produced an increased lighting saving of 2.719 W/m 2 in sunny day as well as 1.687 W/m 2 in cloudy day.
