Urban building energy modeling (UBEM) is a bottom-up, physics-based approach to simulate the thermal performance of new or existing neighborhoods and cities. The field has flourished in recent years, creating increasingly robust urban data streams that lead from Geographical Information Systems, CityGML, Light Detection and Ranging, and tax assessor databases to synthetic hourly building energy demand profiles for current and potential future conditions. Depending on the availability of historic building energy use data, a variety of modeling, simulation, and calibration approaches as well as use cases have been proposed. This paper provides a consolidated UBEM workflow with data and process requirements, and organizes UBEM proposals into four main application categories: urban planning and new neighborhood design, stock-level carbon reduction strategies, individual building-level recommendations, and buildings-to-grid integration. For each application, the paper further introduces a minimum viable UBEM, a novel concept for UBEMs conceptualized in the spirit of a minimum viable product. Specific case studies and/or examples are listed for each application area where available.

城市建筑能源模型（UBEM）是一种基于物理的自底向上方法，用于模拟新的或现有的街区和城市的热力性能。近年来，该领域蓬勃发展，创建了越来越强大的城市数据流，这些数据流从地理信息系统，CityGML，光检测和测距以及税务评估员数据库到针对当前和潜在未来条件的合成每小时建筑能源需求概况。根据历史建筑能源使用数据的可用性，已经提出了各种建模，模拟和校准方法以及用例。本文提供了具有数据和流程要求的合并的UBEM工作流程，并将UBEM建议组织为四个主要应用类别：城市规划和新社区设计，库存级别的碳减排策略，个别建筑物级别的建议以及建筑物到电网的集成。对于每种应用，本文还介绍了最低可行的UBEM，这是一种基于最低可行产品的精神概念化的UBEM新概念。在可用的情况下，列出了每个应用领域的具体案例研究和/或示例。
