The goal of the Perlita Project is to show a new path for low energy consumption buildings in Los Angeles and in Southern California through realistic, affordable and reproducible solutions.
The main focus was the energy efficiency. We followed the PassiveHouse standard path, which is the leading international low energy building standard with more than 85,000 buildingsaround the globe in all climate zones, to deliver ahigh level of comfort with very low energy consumption.
This strategy allowed us to design a site Net Zero Energy, fossil fuel free house, with only 12 solar panels; 4 panels were added to supply all the required electricity for the annual consumption of an electric car used for most of the home owners’ local commute. A storage battery allows to shave peak hours demand.
Of course, the project was designed to be water conscious with only low water consumption fixtures, adrought tolerant landscaping and arain garden. Black water and grey water pipes were also separated to easily use the grey water for the yard.
After the first 12 months of operation, the house is one of the most energy efficient building in Los Angeles with a verified site EUIbelow 39 kWh/m²/yr, which is the maximum total energy consumption allowed for a Passive House. Both certification from the Passive House Institute and from the Living BuildingChallenge are in progress.
This project should be the beginning of a new construction paradigm; more than 300 people already toured the house.

Owner approach of sustainability
The goal of the Perlita Project is to show a new path for low energy consumption buildings in Los Angeles and in Southern California through a realistic, affordable and reproducible solutions which will become the standard in the near future with the new rules which will apply, but also because this is the proper way to build. The Perlita Project is the first Passive House project completed in Los Angeles.
Modern design respecting the vernacular architectural style; Keeping the scale of the existing surrounding houses & Open towards the local community.
If you had to do it again?
For our next project, we will make sure to use Passive House solutions which have been validated by experienced Passive House crews; We will also make sure our architect has experience in Passive House design and therefore for the Passive House principles to be integrated as well as possible into the building design; Lastly we will make sure to have every construction details and MEP systems to be 100% design before starting the construction phase, because decisions we made on site were not as efficient and cost effective that the one we would have thought about before the construction phase.
Building users opinion
Great comfort, indoor air quality and noise reduction from outside noise; And all that without any energy bill!
