This 2026 Summer Study paper addresses how to decarbonize affordable multifamily housing while preserving affordability, improving resident comfort, and supporting healthier, more resilient homes.
This 2026 Summer Study paper discusses how to align building energy codes and building performance policies
An overview of how alternative compliance paths help buildings of all types improve energy efficiency and overall building performance.
As state and local governments look for ways to reduce emissions and improve the affordability and resilience of buildings, a growing number are turning to Building Performance Standards. These policies address energy waste in existing buildings and use multiple alternative compliance paths (ACPs) to provide flexibility. But not all of these alternative pathways are created … Continued
Buildings are more than bricks and walls: they’re where we live, work, and learn. In most large cities in North America, buildings are also the largest source of the greenhouse gas emissions warming our planet.
The report provides a landscape assessment of alternative compliance pathways used for building performance standards nationwide.
This year marks an exciting milestone in our field: the first BPS compliance deadlines are taking effect in cities like New York City, Denver, and St. Louis.
This paper explains the role of efficiency programs in building performance standards (BPS) implementation and considers how the next phase of BPS policies can accelerate an equitable, low-carbon future.
The new definition is a foundation to move us toward a future of high-performing, zero carbon buildings for all of us to live, work, and learn.
At what point do buildings exit the realm of energy codes and enter the realm of BPS? Marshall and Louise detail why we need alignment between the two to effectively decarbonize buildings.
