摘　　要：供暖能耗在建筑总能耗中占较大比例,由此带来的环境影响不容小觑。采用不同的全寿命周期影响评价(LCIA)方法对北方地区办公建筑常用的热源形式进行了评价,同时根据当地环境政策与能源法规建立了本地化的LCIA方法。结果表明:不同LCIA方法在全球变暖、酸化和富营养化方面的评价结果具有一致性;本地化LCIA方法与其他LCIA方法在资源耗竭方面的评价结果相差很大,本地化LCIA方法得出燃油锅炉影响最大。在环境影响加权结果中,本地化LCIA方法评价结果为除燃气热电联产外,地源热泵和燃气锅炉具有一定的环境效益,燃油锅炉的环境效益较差,不值得推广。The heating energy consumption accounts for a large proportion in the total energy consumption of buildings,so its environmental impact cannot be underestimated.Adopts different life cycle impact assessment(LCIA)methods to evaluate the heating sources commonly used in office buildings in northern China,and establishes a localized LCIA method according to local environmental policies and energy regulations.The results show that different LCIA methods have much consistency in the evaluation results of global warming,acidification and eutrophication.The localized LCIA method and other LCIA methods have different evaluation results in resource exhaustion.The former concludes that oil-fired boilers have the greatest impact on resource exhaustion.In the weighted results of environmental impact,the localized LCIA method concludes that ground-source heat pumps and gas-fired boilers have certain environmental benefits,except for the gas-fired cogeneration.Oil・fired boilers are not worth promoting with poor environmental benefits.
