Method: steady-state envelope loss (U × A × ΔT) plus air-change infiltration, with seasonal energy from heating degree days rather than a single design day. Envelope areas are computed from the same 3D geometry the configurator builds and cuts cover to. Real fuel use also depends on wind exposure, humidity, thermal screens, soil heat and how tightly the house is built.
