A completed single-family Passive House in the Bay Area, modeled in PHPP to climate zone 5 (San Jose) — engineered for tight airtightness, low heating demand, and healthy indoor air.
The Passive House Planning Package (PHPP) is the international energy-modeling standard developed by the Passivhaus Institut. The values below are the verified PHPP outputs against the Passive House criteria for climate zone 5 (Warm).
