Cohousing-L Mailing List: Re: Green air conditioning?

[Kevin Wolf (kevin]

Out here in the heat of the Sacramento Valley summers, we have retrofitted our 
houses with white roofs and insulation to great benefit. We also have evening 
breezes and open the houses up at night and close them in the day. Many of us 
have evaporative "swamp" coolers for the worst days when it is above 100.  But 
these latter practices and tools probably don't work in a high humidity area.  
We have 10-30% humidity during the summer so these work well.

Another technique that a local scientist did some studies on use micro spray 
sprinklers on his roof set to a thermostat so every time the roof got to a 
certain temperature, the sprinklers would cool the roof.  He set his interior 
air conditioning at the same level with and without the sprinklers and recorded 
impressive energy savings.  He had a near flat roof so I don't know how it will 
work with roofs pitched for snow.
