The European Unions (EU) Green Deal plans for a carbon neutral economy by 2050. Achieving this goal will require actions across all economic sectors, especially the building sector, which currently accounts for 40% of energy use. Residential energy use is a significant contributor, much of it due to an aging, poorly insulated building stock, much of which is concentrated in urban neighbourhoods. This research focusses on the application of an Urban Building Energy Model (UBEM) to support the Green Deal and the planned ‘renovation wave’. An archetype approach is used to efficiently derive the building data needed to run the Urban Modelling Interface (UMI) to test the efficacy of energy retrofitting policies for neighbourhoods, using a case-study area of 9,000 residential buildings in a European city. Initially, UMI simulations of energy use intensity are evaluated against reported energy performance certificate data in the study area. The UBEM is then used to quantify the most cost-effective mix of envelope retrofit and onsite energy production to achieve a 60% reduction in greenhouse gas emissions by 2030. The methodology shown here is based on residential building archetypes that are available for many EU countries and the method outlined can be replicated in other urban settings.

欧盟 (EU) 绿色协议计划到 2050 年实现碳中和经济。实现这一目标需要所有经济部门采取行动，尤其是目前占能源使用量 40% 的建筑部门。住宅能源使用是一个重要的贡献者，其中很大一部分是由于老化、绝缘不良的建筑存量，其中大部分集中在城市社区。这项研究的重点是应用城市建筑能源模型 (UBEM) 来支持绿色交易和计划中的“改造浪潮”。使用原型方法有效地获取运行城市建模接口 (UMI) 所需的建筑数据，以测试社区能源改造政策的有效性，使用欧洲城市 9,000 座住宅建筑的案例研究区域。原来，能源使用强度的 UMI 模拟是根据研究区域中报告的能源性能证书数据进行评估的。然后使用 UBEM 来量化外壳改造和现场能源生产的最具成本效益的组合，以实现到 2030 年温室气体排放量减少 60%。此处显示的方法基于许多欧盟国家可用的住宅建筑原型并且概述的方法可以在其他城市环境中复制。
