This needs assessment provides the industry needs to establish and implement the BPS from the market perspective.

To support policymakers and interested professionals in this process, ASHRAE convened a BPS Working Group under its Task Force on Building Decarbonization (TFBD) that is working to produce a Technical Resource Guide that guides jurisdictions through the target-setting process and outlines the available methodology options. The guide also provides additional background in metric selection.

This document developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Task Force for Building Decarbonization provides an overview of the BPS development process, including considerations such as performance target-setting, implementation and enforcement timelines, equitable policy application, and compliance support. ASHRAE also compiled a list of BPS Resources and PublicationsPDF that provide an overview of BPS policy elements, performance metrics, relation with new construction, and available compliance tools.

As leading cities and states seek to meet their aggressive climate, energy, and decarbonization goals, they are turning increasingly to mandatory policies that require improved energy and emissions performance across their existing building stock. The most comprehensive of these policies is the 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 both buildings and fuels in performance standard legislation.
