[44] An active solar energy system analysis program may be used to optimize the solar pool heating system ...
A pioneering figure of this type of system was George Löf, who built a solar-heated air system in 1945 for a house in Boulder, Colorado. He later included a gravel bed for heat storage. [citation needed] Ventilation, fresh air or makeup air is required in most commercial, industrial and institutional buildings to meet code requirements.
