The main driver for the performance and affordability of the recently-mentioned Rainbow Duplex is a panelized prefab system of construction that was designed to help projects meet the Passive House standard. BC Passive House in Canada has a manufacturing plant that’s making these panels, and I thought it would be interesting to share what’s inside the company’s next-gen, high-performance panels.
This is a follow-up with new photos to our original coverage of an affordable Passive House duplex located near an affluent ski resort in British Columbia. Referred to as the Rainbow Duplex, the home was designed by Marken Projects and built by Durfield Constructors with a high-performance, panelized prefab system by BC Passive House.
One thing I’ve noticed is the fact that home building is changing in a big way. In order to capture what’s going on across the country, I thought it would be interesting to talk with influencers and innovators about things like tiny houses, prefabrication, sustainable design, high performance construction, and home technology. For this first interview, I was able to exchange emails with Sam Hagerman, co-owner of Hammer & Hand and president of the Passive House Alliance US, on the topic of ADUs and Passive Houses.
Recently I realized that we neglected to follow up on a Passive House project discussed in pre-construction way back in March 2010. It turns out the New England Passive House, or Little Compton Retreat, received LEED Gold certification from the USGBC in recent months. The background is this is a home by ZeroEnergy Design, who performed mechanical and architecture services, and Aedi Construction, who built the home.
The Passive House movement in the US was on a major tear in 2011 but for that awful split between PHIUS and international PHI. The standard seemed free of maneuvers and politics and infighting, yet now there’s something about PHIUS+ certification and a ban on spray polyurethane foam insulation. Oh boy! Notwithstanding all of this, let’s not take anything from the following incredible, high-performance, completed projects discussed in the past year that sought or achieved Passive House certification.
When we first profiled Anchorage Builders in 2010, they were in the construction phase of North Carolina’s first Passive House. We followed up with the project in a subsequent post and were quite impressed with the completed home, both aesthetically and sustainably. Building on this successful experience, Anchorage and architect Jay Fulkerson have recently collaborated on yet another Chapel Hill home designed with Passive House building methods.
