Passive House | Project Tour

“Passive House SB9 & ADUs in CA’s Milder Climates” marked the first in-person Passive House California home tour in West Los Angeles, held in May 2024. Visitors had the unique opportunity to explore an all electric small-scale Passive House Accessory Dwelling Unit (ADU) and a Single-Family Residence under SB9, both under construction in Los Angeles and designed by PARAVANT Architects. During the tour, attendees observed the installation of dense pack…


“Performance Advantages of Air-To-Water Heat Pumps”

Heat pumps are the future of heating and water heating not just in the USA but around the world. Heat pumps, through the near-magic of a carefully designed refrigerant circuit, transfer heat rather than creating heat through combustion or electrical resistance. In doing so, heat pumps achieve efficiencies and “coefficients of performance” between 250% and 500%. Air-to-water heat pumps, like Stiebel Eltron’s WPL monobloc heat pump can provide super high…


Passive House SB9 & ADUs in CA’s Milder Climates

Passive House design is becoming increasingly popular in Southern California due to its focus on energy efficiency, making it a leading example of high-performance design and construction in the region. Passive House protocols provide homeowners improved comfort, indoor air quality, and resilience to extreme weather, fires, smoke, and power outages, as well as a more durable home that consumes less energy. Join us to discover the implications of California's SB9…


“17 Mile Haus: A Passive House Design Journey”

Passive House design is receiving heightened interest across the country due to growing awareness of the impact of buildings on carbon emissions. This presentation will look at how Passive House is applicable here in California, using a project located on Pebble Beach’s storied 17 Mile Drive. Join us to learn about the evolution of this design, the details that support how it performs, plus a look at the impact of the…


The Benefits of Right-Sizing Plumbing in Homes & Apartment Buildings

Effective July 1, 2024, the Appendix M, Peak Water Demand Calculator (WDC) will become part of the California Plumbing Code. Instead of using flow rates and flush volumes from the 1940s, the WDC will allow you to “right-size” the cold and hot water distribution systems in homes and apartment buildings using modern information about flow rates and simultaneous use. Does this sound like a snoozer? Actually, it is an environmentally…

Passive House California Virtual Community Meeting | Exterior Shading Devices | Recording

In most of California’s climate zones it makes sense to select and position shading devices can have significant impact on comfort and energy consumption. Taking advantage of solar heat gain (SHG) in winter can significantly reduce heating demand, while minimizing SHG in the warmer months can moderate cooling demand and avoid overheating. The presentation will: Share results of studies showing the most effective ways to employ solar shading Review differences…


Passive House California Virtual Community Meeting | Communicating the Value of High-Performance

There are many professionals associated with the building industry (architects, engineers, builders, jurisdiction personnel, etc.) who recognize and support the high-performance of Passive House — but find it difficult to successfully communicate the value of high-performance to others who are not familiar with the benefits of Passive House principles. This presentation and Q & A will focus on ways to persuasively communicate the logic of choosing high-performance for the design…
