Sensitivity studies on elements of meteorological data for building energy simulation in China

As well known, Hourly weather data should be available before running building energy consumption simulation.A large number of Chinese locations have only six-hourly or daily measured weather data, because observed data are not easily obtained or not digitalized. Measured hourly, sixhourly and daily weather data for four cities in China, namely Xi’an, Kunming, Hangzhou and Shantou were gathered and analyzed. Three climatic variables, namely dry-bulb temperature, relative humidity and atmospheric pressure, were investigated. Some methods of interpolation or meteorological models are applicable, such as linear interpolation, cubic spline interpolation and Fourier’s progression interpolation. The sensitivity of climatic variables on building energy consumption were discussed.
