Local Passive House Design and Building Projects

Projects in the San Diego region.

Casa Aguila is targeted to be San Diego County's first Passive House upon completion and final certification.  The home is being constructed by Alliance Green Builders, and is also seeking LEED for Homes Platinum certification.

Because of California's stringent energy codes, there is the potential for any home built in San Diego to achieve the Passive House standard doing little more than is already required by code.  Keeping Passive House principles in mind, a home in this region can be designed and built as a Passive House at little additional cost, yet offer huge ongoing savings on energy bills. Eliminating the need for expensive heating and cooling systems may even allow for Passive Houses to be constructed at less cost than conventional homes.

National Passive House Design and Building Projects

Some projects throughout the United States


Architect: Jarrod Denton

Located just blocks off the plaza in historic downtown Sonoma, PassivWorks has built the first Certified Passive House™ in California and the first Certified Passive House™ retrofit in the country.

The existing house was a run down,1,933 sf eyesore without a street-front entry and in an odd configuration consisting of two separate structures connected by an outdoor breezeway. Cathy had purchased the home based on its location and its “good bones.” Zoning requirements and expansive soil on the site required that the footprint of the building be unchanged and that the existing uninsulated concrete slab floors remain. The solar orientation of the house was not ideal and there was a 30-foot Chinese Pistache tree that would have to be moved in order to make room for the new covered porch on the west side.

Architect Jarrod Denton devised a beautiful solution to the odd structure by connecting the two existing parts with a long, angled corridor that would house the new kitchen and frame the courtyard, making the house into a U-shape and adding an additional 400 sf to the house.

The Center for Energy Efficient Design (CEED) in Franklin County, Va., is the first public school (K-12) in the United States designed to the Passivhaus building performance standard. From conception, CEED was intended to act as both a classroom for advanced placement environmental studies studentsand as a practical demonstration of sustainable building practices. In addition, this new learning center was intended to be a demonstration project for Southwest Virginia and the mid-Atlantic region, open to surrounding schools jurisdictions as well as having its real time data and curriculum available on the internet for long distance teaching. The location is a rural setting in a mild mixed humid climate, and the building is situated at an altitude of approximately 1,050 ft. above sea level.
