  3. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    A heat pump might use 1 J for every 4 J it delivers giving a COP of 4. A system that only uses a 30 W fan to more-evenly distribute 10 kW of solar heat through an entire house would have a COP of 300. Passive solar building design is often a foundational element of a cost-effective zero energy building.
