New Single-Family Residence in Los Angeles Achieves Official Passive House Institute Certification! Congratulations to the team for successfully completing certification!

This SB-9 project embraces California's forward-thinking regulations to combat the housing shortage in Los Angeles by introducing additional residential units. Designed to meet the rigorous International Passive House Standard, it ensures superior energy efficiency, exceptional comfort, and outstanding indoor air quality.

The International Passive House Standard represents a globally recognized benchmark for energy-efficient building design. It focuses on principles like airtight construction, high-performance insulation, thermal bridge-free design, optimized ventilation with heat recovery, and the use of high-quality windows. These elements combine to create homes that are not only energy-efficient but also provide unparalleled comfort, reduced utility costs, a smaller environmental footprint, and enhanced acoustic performance.

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.

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.
