世界各地的许多政府都在为减少政府/公共建筑的能源使用设定更严格的目标。10年前建造的建筑占建筑存量能源的主要份额。然而，业主指导的能源改造项目的资金和“技术诀窍”（应用知识）没有跟上新的要求。在典型的改造项目中，能源使用的减少在10%到20%之间，而全球执行项目的经验表明- 减少使用量可超过50%，翻新建筑可经济高效地达到被动房屋标准或甚至接近净零能耗状态（Hermlink和Muller，2010年；NBI 2014年；RICS 2013年；GreenBuildingAdvisor.com2013年；Shonder和Nasseri 2015年；Miller和Higgins 2015年；Emmerich等人，2011年）。此前根据国际能源署的建筑和社区能源计划（IEA EBC）附件46开展的研究确定并分析了400多项可用于建筑改造的能效措施。 措施包括与建筑围护结构、机械和照明系统、能源生产和分配以及内部流程相关的措施。实施一些单独的措施（如建筑围护结构隔热、提高气密性和热电联产）可以显著降低建筑热负荷和冷负荷，或最大限度地减少能源浪费，但需要大量投资和长期回报。然而，当有限数量的核心技术一起实施或捆绑在一起时，它们可以以较小的投资显著减少能源使用，从而提供更快的回报。 在一些国家，节能绩效合同（ESPC）已被证明是实施能源改造项目的有效工具。然而，在许多国家，由ESPC资助的项目数量仍然不构成公共机构能源改造预算总投资的重要部分。本文介绍了这一概念和几个案例研究，阐明了提高深度能源改造（DER）接受度的机制，并扩大了使用ESPC对现有建筑进行全面翻新的接受度。 引文:2015年年度会议，佐治亚州亚特兰大，2015年交易，第121卷。2.

Many governments worldwide are setting more stringenttargets for reductions in energy use in government/publicbuildings. Buildings constructed more than 10 years agoaccount for a major share of energy used by the building stock.However, the funding and "know-how" (applied knowledge)available for owner-directed energy retrofit projects has notkept pace with newrequirements.With typical retrofit projects,reduction of energy use varies between 10% and 20%, whileexperience fromexecuted projects around the globe shows thatenergy-use reduction can exceed 50%, and renovated buildingscan cost-effectively achieve the passive-house standard oreven approach net zero energy status (Hermelink and Muller,2010; NBI 2014; RICS 2013; GreenBuildingAdvisor.com2013; Shonder and Nasseri 2015; Miller and Higgins 2015;Emmerich et al. 2011). Previous research conducted under theInternational Energy Agency's Energy in Buildings andCommunities Program (IEA EBC) Annex 46 identified andanalyzed more than 400 energy-efficiency measures that canbe used when buildings are retrofitted. Measures include thoserelated to the building envelope, mechanical and lightingsystems, energy generation and distribution, and internalprocesses. Implementation of some individual measures (suchas building envelope insulation, improved airtightness, andcogeneration) can significantly reduce building heating andcooling loads or minimize of energy waste, but require significantinvestments with long paybacks.However, when a limitednumber of core technologies are implemented together, orbundled, they can significantly reduce energy use for a smallerinvestment, thereby providing a faster payback.In some countries, energy savings performance contracts(ESPC) have proven to be an effective tool for implementingenergy retrofit projects. Nevertheless, in many countries thenumber of projects funded by ESPCs still do not form a significantpart of the total investment budgeted by public institutionsfor energy retrofits. This paper presents the concept andseveral case studies that illustrate mechanisms that willincrease the acceptance of deep energy retrofit (DER) andbroaden acceptance of its implementation using ESPCs for acomprehensive refurbishment of existing buildings.
