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’s imperative for architects, developers and planners to address the heightened risk of wildfires in their designs.

Passive House 2 was an exploration in both resistance to wildfires and energy efficiency. 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. Eaves are eliminated to ensure embers do not get trapped at the roof level in the event of a wildfire. A gutter guard is used to minimize accumulation of needles and leaves in gutters. A buffer zone (defensible space) would be created around the house to minimize risk of fire breaking out directly next to the building.
