Effect of several methods for generating typical meteorological year on building energy consumption

Researches the difference of the typical meteorological years (TMY) generated by four methods, namely Sandia, CSWD, CTYW and TPCY, and the effect on the simulation of the building energy consumption in Xi’an using the same meteorological data of thirty-year period. The results show that the selected TMY is repeated and the difference is very small when selecting the top five items as priority in the above four methods. The simulated energy consumption with the TMY selected by the CTYW method is the most close to the simulated energy consumption year by year, and the relative standard deviation is 10.37%, followed by TPCY, CSWD and Sandia methods.
