In October, 2021, Connecticut-based builder Ben Bogie of BPC Green Builders broke ground on a trailblazing project in the Hudson River Valley (climate zone 5). A collaboration with Trillium Architects, the 5000-sq.-ft. house is Japanese pagoda–inspired and promises to be lesson-rich. The overarching goal is to use building science–based best practices—products, techniques, and assemblies—to construct a high-performance, net-positive house. Keeping upfront carbon emissions to a minimum is a key objective. To that end, the project minimizes the use of virgin foam insulation, reduces concrete where feasible, is engineered to avoid the need for steel, and optimizes materials made of recycled content.
GBA will follow this build and share key construction details along the way. This is the first episode in an 11-episode video series. It looks at an insulating composite concrete form (ICCF) foundation, specifically The Perfect Block from Eco Building Systems.
