随着主要城市和州寻求实现其积极的气候、能源和脱碳目标，它们越来越多地转向强制性政策，要求改善现有建筑存量的能源和排放性能。这些政策中最全面的是buildingperformance standard（BPS），其中设置了性能阈值，建筑物所有者必须在指定时间或触发事件发生时满足这些阈值。BPS可以解决一系列排放、能源和电网相关的目标。本文探讨了在性能标准立法中，为建筑物和燃料设定关键指标所采用的技术方法。其中一些指标包括每平方英尺的排放水平、每平方英尺的能源消耗和每千瓦的温室气体磅数- 消耗了一个小时。本文将考虑如何设置现有建筑物的标准，包括ASHRAE Standard 100和ASHRAE标准105，在设置这些参数时被引用。BPS中这些指标的方法和水平直接影响建筑业主将采取哪些措施来满足其技术要求。指标、合规期和设备更换周期之间的细微关系会极大地影响BPS与辖区气候政策目标的一致程度。本文还分析并解释了新建筑标准（包括ASHRAE标准90.1和ASHRAE标准189.1）中的绩效水平与BPS的指标和绩效水平之间的关系- 着眼于确保新建建筑的位置符合拟议的BPS。在总结了BPS标准制定过程中涉及的技术问题之后，本文为数据收集、建筑存量数据分析和BPS语言编制中的情景规划提供了一系列建议。引文:2021篇虚拟会议论文

As leading cities and states seek to meet their aggressive climate, energy, and decarbonization goals, they are turning increasingly to mandatory policiesthat require improved energy and emissions performance across their existing building stock. The most comprehensive of these policies is the buildingperformance standard (BPS), in which performance thresholds are set that building owners must meet at a specified time or when a triggering event occurs.A BPS can address a range of emissions, energy and grid-related goals. This paper examines technical approaches used to set the key metrics for bothbuildings and fuels in performance standard legislation. Some of these metrics include emissions levels per square foot, energy use per square foot, andpounds of greenhouse gases per kilowatt-hour consumed. The paper will consider how standards for existing buildings, including ASHRAE Standard100 and ASHRAE Standard 105, are being referenced in setting these parameters. The methodology and level of these metrics in a BPS directlyimpacts which actions will be taken by building owners to meet its technical requirements. Nuanced relationships between metrics, compliance periods, andequipment replacement cycles can greatly influence the degree to which a BPS is aligned with a jurisdiction’s climate policy goals The paper also analyzesand explains how performance levels in standards for new construction, including ASHRAE Standard 90.1 and ASHRAE Standard 189.1, relateto the metrics and performance levels of BPS - with an eye to ensuring that newly constructed buildings will be positioned to meet a proposed BPS.Following concluding summaries on the technical issues involved in BPS standard-setting, the paper provides a range of recommendations for datacollection, analysis of building stock data, and scenario planning in the preparation of BPS language.
