摘要
随着存量建筑增多,既有建筑综合改造对减少全球能耗和碳排放发挥越来越重要的作用,以往的建筑碳排放多关注于新建建筑,近年来越来越多的学者开始关注改造建筑的碳排放.文章首先对研究中广泛出现的减碳改造措施进行总结,包括被动式技术、主动式技术、可再生能源技术,再对既有研究中应用较多且具有发展前景的改造措施碳排放量化预测方法进行对比分析,包括单一或组合措施的碳排放量化、改造方案碳排放计算、改造措施的选择方式等,最后从改造措施、量化方法、隐含碳排放、改造决策等方面对既有研究进行分析展望,为相关学者提供理论参考.
Abstract
With the increase of existing buildings,the comprehensive renovation of existing buildings plays an increasingly important role in reducing global energy consumption and carbon emissions.Previous studies of carbon emissions have mostly focused on new buildings,but an increasingly number of scholars have begun to pay attention to the carbon emissions of building renovation in recent years.This paper first summarized the carbon reduction retrofit measures that often appeared in existing research,including passive strategies,active technologies and renewable energy technologies.Then,a comparative analysis was conducted on the quantitative prediction methods for carbon emissions of retrofit measures that were widely used in existing research and have development prospects,including the quantification of carbon emissions of single or combined measures,the calculation of carbon emissions of renovation schemes,the selection of retrofit measures,etc.Last,existing studies were analyzed and explored for their prospects in terms of retrofit measures,quantitative methods,embodied carbon emissions,renovation decisions,etc.,to provide theoretical reference for relevant scholars.
