Abstract: | This research focuses on physiological equivalent temperature (PET), a thermal index, situated in Central, Hong Kong, a financial center gathering numerous people. under the 'Smart cities building' background to realize cost-beneficial effect. Research data, air temperature, relative humidity and wind speed, includes two parts, one is measuring data used for RayMan PET model and the other one is government data used for ENVI_Met PET model. The PET differences between RayMan model and ENVI_Met model are reasonable. By comparing with RayMan model, researcher analyzes ENVI_Met model under conditions of weather, time and location. PET in Central is higher than air temperature in the morning and at noon, while it is lower in the afternoon. PET change depends on its location. PET of the area beside the sea and under high sunlight changes faster than that inside the building clusters and PET at higher altitude places is relatively lower. And ENVI_Met PET model applications are demonstrated on two respects, time series: months, seasons and year, and special dates: Summer Solstice, Winter Solstice, heavy rain day and Columba typhoon day. PET on heavy day and the days before or after it doesn't change obviously while it on Columba typhoon day declines sharply compared with the days before or after typhoon day. At last, the conclusions, shortage and further discussion of this research are illustrated. |
