Abstract:

This paper compared the changes in climate zoning for buildings between 1951-1980 and 1981-2010 using monthly average temperature data and discussed the change characteristics of climatic conditions for heating from 1951 to 2018 using daily average temperature data.The results show that compared with the period from 1951 to 1980, the range of severe cold area decreases from 1981 to 2010, and the southern boundary moves northward.The cold area, the hot-summer and cold-winter area, the hot-summer and warm-winter area move northward.However, the mild area expands westward, and the range of hot-summer and warm-winter area becomes larger.From 1951 to 2018, the heating degree day in all building climate zones decreases significantly.The largest reduction rate is in the severe cold area and the smallest is in the mild area.The anomaly percentage of heating degree day has a big fluctuate in the hot-summer and cold-winter area, and has a small fluctuate in the severe cold area.During the period of 1998 to 2012, the heating degree day and the average daily heating intensity of all building climate zones increased, and the trend of hot-summer and warm-winter area passes the 0.05 significance test.

Key words: China, Climate zoning for buildings, Heating
