摘要
This paper investigated the variation of build- ing heating energy consumption caused by global warming in Tianjin, China. Based on the hourly historical and monthly projected future （B1/A1B emissions scenarios） meteorological data, the variation of those relevant meteorological parameters was first analyzed. A TRNSYS simulation model for a reference building was introduced to investigate historical variation of office building energy consumption. The results showed that the 10-year-average heating energy consumption of 2001-2010 had reduced by 16.1% compared to that of 1961-1970. By conducting principal component analysis and regression analysis, future variation of building heating load was studied. For B1/A1B emissions scenarios, the multi-year-average heating load was found to decrease by 9.7% （18.1%）/ 10.2% （22.7%） compared to that of 1971-2010 by 2011- 2050 （2051-2100）.
