I'm sure it's been tried but has anyone water cooled a roof for summer cooling savings?
Since the cooling load of a building is mostly from the exterior and mainly the attic what better than to cool the roof?
I am thinking of circulating water from the eves to the peak with an efficient sump pump and letting the evaporative effect do the cooling much like a cooling tower.
Also a possibility would be evaporative cooled water from the north side of the roof to circulate through a 4" pan holding the air conditioner outside condenser unit.
All electrical raised above the water level of course.
Water treated for bacteria.
Would this do any effective cooling?
