Passive House Los Angeles

USA


Innovation and Sustainability Christian Kienapfel

Passive House Los Angeles (PHLA+) is the first newly built “Certified Passive House” in Los Angeles close to the Los Angeles international airport and Beverly Hills. “Passive House” is a fast growing international building construction performance standard combining comfort with very low energy consumption and at the same time providing a high indoor air quality. It is strategically planned to showcase the technologies and benefits of the “Passive House Standard”, including home health, efficient energy use, and sustainable building practices. With those attributes, this makes PHLA+ a Zero Net Energy (ZNE) home. The project aims to educate potential owners about the benefits of Passive House design, emphasizing energy cost savings and quantifiable home health benefits based on actual performance.

Key Achievements

  • Passive House Certification was achieved for the home. This was the primary goal of the home, which was used as a showcase home by the architect.
  • Passive House Los Angeles received recognition by the American Institute of Architecture and was honored with the Cote Merit Award.

Key Challenges

Passive House certification - North American building scientists and builders with funding from the U.S. Department of Energy (DOE) and the Canadian government were the first to pioneer passive building principles in the 1970s.

In cooperation with Building Science Corporation under a U.S. DOE Building America Grant, the PHIUS Technical Committee developed passive building standards that account for the broad range of climate conditions, market conditions, and other variables in North American climate zones. The result is the PHIUS+ 2015 Passive Building Standard – North America, which was released in March of 2015.

Contemporary Design - The contemporary design applies modern drywall materials contributing to achieving indoor air quality and acoustic performance design requirements, which are key components of part of Passive House performance standards.
