Passive House LA+ (PHLA+) Tour

Passive House LA+ (PHLA+), a recently completed home in Culver City, California, is one of the most energy efficient homes constructed in Los Angeles County. Achieving many firsts for a residence in the region, it is a Certified Passive House, a Zero Net Energy home (ZNE), and among the first Passive Houses built in Southern California.

PHLA+ is a project designed by PARAVANT Architects, and is strategically planned to showcase the back-end technologies and benefits of the Passive House building standard. Christian Kienapfel, both the homeowner and project architect, began this project with the goal of building a home that could be an example of what’s possible for the Southern California region in Passive House building. As such, PHLA+ will be a case study and demonstration project that will be open to educate and inform the Los Angeles Design/Build community.

PHLA+ is located on a duplex lot, an infill site, and is comprised of 1,750 sq.ft. of living area with an additional large deck area over a carport. The home has four bedrooms and three bathrooms. Large windows provide sufficient natural daylight and a connection between indoor and outdoor living even with this home’s limited footprint. Exterior fully automated venetian blinds reduce internal heat gain, and glare, effectively keeping the house cooler and comfortable. The entire building envelope including the windows, wall systems, airtightness and insulation are combined to produce bottom line, significant energy cost savings not possible with conventional building practices. The goal of healthy indoor air quality is met by continuous ventilation in combination with a highly efficient heat-recovery ventilator (HRV).

PHLA+ is a fossil (gas) free home using electrification as a decarburization strategy. This all electric building is using a high efficient heat pump water heater, induction cook top, convection oven and condensation dryer. A ~5.4kW (5,360 watts) photovoltaic system with a 14 kWh storage battery makes this home 93% self performing relying only for a very small percentage of power from the electric grid. All these measures make this home net zero – or possibly plus – energy, reducing the utility bills for a lifetime.
