According to the National Oceanic and Atmospheric Administration, “with continued high emissions of greenhouse gases, models project that the risk of very large wildfires will increase by up to six-fold in parts of the United States by mid-century.” It is imperative for architects, developers and planners to address the heightened risk of wildfires in their designs.

Passive House 003 is a study in a series of homes by Clutch Design Studio, and is an exploration in both resistance to wildfires, as well as energy efficiency based on the PHIUS Passive House Building Principles. Per PHIUS recommendations, the house maintains a compact design with southern exposure. Super continuous insulation and an airtight envelope contribute to an exceptionally quiet and energy efficient design. Fire resistance is achieved by utilizing non-combustible materials on the exterior of the building including metal panel cladding, non-combustible mineral wool insulation and a metal roof. Roof overhangs are eliminated to ensure embers are not trapped by eaves in the event of a wildfire. Further explorations include gutter guards to minimize accumulation of needles and leaves. A buffer zone (defensible space) would be created around the house to minimize risk of fire spreading directly next to the structure.
