Abstract

As interest in district-level approaches for design and renovation of the built environment grows, new technical solutions have been developing and there is an increasing diversity of technologies and measures available. A characterization of the available solutions and of their adoption in practice is performed, using a meta-analysis of a selection of case studies depicting district interventions in Europe, based on a comprehensive literature review. The analysis included categorization of measures and technologies, quantification of their occurrence in the case-studies, how their impact was evaluated, and which performance indicators were used. Results showed that the majority of carbon emissions and economic savings were related to improved energy performance. The technical measures more often declared concerned energy supply, especially photovoltaic panels, followed by options for HVAC and DHW. A wide variety of indicators for performance assessment was found. The most prevalent ones are from the category of energy performance, followed by economic cost and carbon emissions. The work concludes with an analysis for the impact of the measures on the several categories of performance. Measures seldom adopted that showed good potential to contribute to impactful solutions were also identified.

区域层面能源、碳和经济目标解决方案的元分析

随着人们对建筑环境设计和改造的地区级方法的兴趣与日俱增，新的技术解决方案也在不断发展，可用的技术和措施也越来越多样化。本报告以全面的文献综述为基础，通过对描述欧洲地区干预措施的精选案例研究进行元分析，对现有解决方案及其在实践中的采用情况进行了描述。分析包括措施和技术的分类、案例研究中出现的措施和技术的量化、如何评估其影响以及使用了哪些绩效指标。结果表明，大部分碳排放和经济节约都与提高能源绩效有关。技术措施更多涉及能源供应，尤其是光伏电池板，其次是暖通空调和热水供应。绩效评估指标种类繁多。最常见的是能源性能指标，其次是经济成本和碳排放。最后，分析了这些措施对几类性能的影响。此外，还确定了一些很少采用的措施，但这些措施显示出促进有影响力的解决方案的良好潜力。
