Climatic Zoning for the Thermal Design of Residences in China Based on Heating Degree-Days and Cooling Degree-Hours

Abstract

In this paper, using the integrated surface observations for 430 Chinese locations, equations for estimating heating degree-days and cooling degree-hours were developed. The distribution of heating degree-days and cooling degree-hours was clarified and contour maps of heating degree-days and cooling degree-hours were created. Based on these maps, a new climatic zoning was proposed for the thermal design of residences in China.
