SAMPLE LETTER
Dear Representative ________,
I am writing to express my support for AB 368 and its recognition of certified Passive House standards as a key tool in reducing California’s building-related carbon emissions.
[Use this space to personalize your letter by sharing your experience with a project, living or working in Passive House, or your thoughts on the benefits of this bill.]
Buildings generate 25% of the state’s greenhouse gas emissions. Without stronger efficiency measures, we risk locking in high emissions for decades. Incorporating Passive House as an alternative compliance pathway to Title 24 will accelerate California’s shift to clean, all-electric buildings while easing grid strain.
Passive House standards cut heating and cooling energy use by up to 90%, reducing fossil fuel reliance and ensuring long-term affordability. They also improve air quality, enhance resilience to extreme weather, and lower fire risk—critical benefits for vulnerable communities and economies statewide.
We have the expertise to build safer, healthier, and more efficient buildings. AB 368 will make high-performance buildings more affordable and accessible while helping California meet climate goals faster.
Thank you.
Sincerely,
[Your name, city, and zip code]
