AbstractThis paper proposes a method to predict the hourly Hong Kong representative sky from Typical Meteorological Year data. An evaluation of the sensitivity of the vertical sky component demonstrates that the Hong Kong representative sky can provide better results than the Perez all-weather sky model. Error reductions of 9-23% can be expected in the four cardinal directions. To predict the Hong Kong representative sky from the Typical Meteorological Year data, a clear sky index can be derived from global horizontal irradiance. Three Hong Kong representative skies can be classified by the clear sky index corresponding to skies 1, 8 and 13 of the Hong Kong representative sky, respectively. The predicted hourly Hong Kong representative sky can provide the sky luminance data for the dynamic simulation of buildings.
