Effects of long-term climate change on global building energy expenditures
研究了气候变化对全球建筑能源支出的影响，发现制冷用电增加导致支出上升，但不同地区因取暖需求减少而抵消程度不同，加拿大和俄罗斯等取暖主导区净支出下降，而制冷需求大的地区支出增加。
Our paper explores potential future implications of climate change on building energy expenditures around the globe. Increasing expenditures result from increased electricity use for cooling, and are offset to varying degrees, depending on the region, by decreased energy consumption for heating. WE conducted an analysis using a model of the global buildings sector within the GCAM integrated assessment model. The integrated assessment framework is valuable because it represents socioeconomic and energy system changes that will be important for understanding building energy expenditures in the future. Results indicate that changes in net expenditures are not uniform across the globe. Net expenditures decrease in some regions, such as Canada and Russia, where heating demands currently dominate, and increase the most in areas with less demand for space heating and greater demand for space cooling. We explain these results in terms of the basic drivers that link building energy expenditures to regional climate.
