Building Codes

States have started to introduce building code language that acknowledges Passive House design as a legitimate indication of code compliance. It is a small but important step in the normalization of the Passive House approach in meeting state energy and carbon emissions reduction goals. Here is a collection of policy and code documents that reference Passive House, across the US. Check back as we will be updating this page as new information warrants.

Mass Building Code Update with Passive House

Massachusetts Residential Building Code

The 9th Edition of the State Building Code Amendments includes explicit reference to Passive House, recognizing the use of “approved software” by PHI, aka the Passive House Planning Package or PHPP, and certified as a Passive House to demonstrate energy code compliance. See the State code page here.

NYS Stretch Energy Code Update with Passive House

New York State Residential Stretch Energy Code – 2020

The 2020 update to the State Building Energy Stretch Code, Passive House is explicitly recognized, like Massachusetts before as an alternate pathway of compliance. And like Massachusettes, they don’t require meeting the full Passive House thresholds but indicate the “Low Energy Building” certification performance levels as sufficient. See the State code page here.

NYS Stretch Energy Code Update with Passive House

Washington State Residential Energy Code – 2018

The 2018 update to the State Building Energy Stretch Code, Passive House is explicitly recognized, like the others before as an alternate pathway of compliance.
