Abstract: The effects of climate change on building climate zones in China were investigated by using the recent 55-year (1961-2015) meteorological observation data. The results show that the building climate zones have largely changed under climate warming. The changed areas were 31.8 × 104 km2, 70.0 ×104 km2 and 78.5 ×104 km2 for the periods of 1971-2000, 1981-2010, and 1991-2015 relative to 1961-1990, accounting for 3.4%, 7.4%, and 8.3% of the land surface. Among the five climate zones, the severe cold zone has reduced, whereas the other four climate zones have expanded, with the largest expansion occurring in cold zone. The major transition was from severe cold to cold zones. The results in this study suggest that climate change has apparent effects on building climate zones in China. Hence, new climate zones should be reformulated, and accurate building design strategies are urgently needed.
