A Proposed Model for Building Energy Lighting Simulation

摘要

The use of building lighting simulation has increased in recent years, due to the growing demands of economic consequences from energy consumed by electricity in buildings. The building energy efficiency is of high priority in many countries of the world. This research investigates the important underlying issues affecting the effective use of one of the most powerful computational lighting simulation software, ECOTECT, to assist in the daylighting design of an actual building. The validation studies, which were carried out in the UWE in Bristol, U.K. revealed that ECOTECT can be used to predict the internal illuminance with a high degree of accuracy under overcast sky conditions. This is of particular concern for commercial and institutional buildings.
