在欧盟 (EU)，住宅部门的能源消耗约占总能源消耗的 40%。成员国现有的建筑存量效率低下，可以而且必须进行改造。本文介绍了一种创新方法，用于分析改造现有建筑群的潜在节能效果。特别是，本研究考虑了实施可行的能源效率措施的实际技术和经济限制。该分析适用于米兰省五个签署了市长盟约的城市，承诺到2020年达到并超过欧盟二氧化碳减排20%的目标。由于分析的规模是城市，因此所需数据的分辨率很高。为了实现现实且可实现的节能，我们建立了能源地籍，并对每个城市进行了大规模的现场调查。通过检测建筑群的特征，我们能够了解哪些能源改造干预措施从技术、法律和经济角度是可行的。其结果是一个不会高估潜在节能潜力的工具，有助于公共行政部门制定节能政策。 (C) 2012 Elsevier B.V. 保留所有权利。
In the European Union (EU), the residential sector is responsible for approximately 40% of the total energy consumption. The existing building stock of member states is inefficient and can and must be retrofitted. This paper describes an innovative approach for the analysis of the potential energy savings of retrofitting existing building stocks. In particular, this study considers the actual technological and economic constraints of the implementation of feasible energy efficiency measures.The analysis was applied to five municipalities in the province of Milan that have signed the Covenant of Mayors, committing to meet and exceed the 20% CO2 reduction objective of the EU by 2020. Because the scale of the analysis is municipal, the resolution of the requested data is high. In order to achieve realistic and achievable energy savings, we realise an energy cadastre and conduct a large in-field survey for each municipality. By detecting the characteristics of the building stock, we are able to know which energy retrofit interventions are feasible from a technical, legal and economic point of view. The result is a tool that does not overestimate the potential energy savings, helping the public administration make energy saving policies. (C) 2012 Elsevier B.V. All rights reserved.
