The 20% Stretch Code Provisions measures are the first outcome of a larger project that is focused directly on the technical development of stretch codes and standards, and on support for jurisdictions in adopting and implementing these policies. As jurisdictions move forward with the adoption of codes and policies that support building stock performance improvement, a set of increasingly stringent performance metrics are anticipated, ranging from a 20% improvement over baseline code performance to a policy that delivers zero energy performance in buildings.
The costs of building energy improvement could be prohibitive for many affordable multifamily property owners and managers, but exempting them misses an opportunity to decarbonize buildings and improve energy equity for residents. This paper identifies potential solutions for improved energy performance of affordable housing.
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.
The Building Decarbonization Code is a groundbreaking tool aiming to deliver carbon neutral performance. The Version 1.2 code language from NBI serves as a building decarbonization overlay to the 2021 International Energy Conservation Code (IECC) and is now compatible with ASHRAE 90.1. It is designed to help states and cities working to mitigate carbon resulting from energy use in the built environment, which accounts for 39% of U.S. emissions.
For cities exploring and implementing building performance standards, a high-performance building hub provides critical guidance, technical assistance, or access to available incentives to building owners, designers, contractors, and operators.
Preparing for Building Policy: This resource aims to enhance city personnel perspectives on how the real estate industry functions—including how different market actors work together throughout the various phases of a building’s lifecycle—and foster more meaningful conversations with stakeholders.
