Climate and performance considerations

Compare the exact product configuration and opening conditions rather than treating a citywide pattern as a prescription for one home.

NOAA 1991-2020 normals recorded at HUDSON 1 SSE, NH US show roughly 6,815 annual heating degree days against 625 cooling degree days, which indicates whether heat loss or heat gain should lead the window comparison. Station normals describe the recording station's location, not any specific property.
