SIMULATION OF ANNUAL DAYLIGHT PERFORMANCE UNDER HONG KONG REPRESENTATIVE SKIES FOR USINE LIGHTING ENERGY INTELLIGENTLY

摘要

This on-going study proposes a method to predict hourly Hong Kong Representative Sky (HKRS) by hourly irradiance data from Typical Meteorological Year (TMY) data. Rather than being based on the traditional static simulation only under CIE overcast sky, the annual daylight performance of buildings in high-density Hong Kong can use the hourly HKRS to assess the "real "daylight performance during a whole year for using artificial lighting energy intelligently.
