      Hi there...
      In the summer in order to keep my house cool I just use a rice cooker and crock pot and plug it outside on my patio. It is easy since I don't have to keep up with it when I am working on the garden and It does not heat up the inside of my house and I can get a hot meal. I have a gas stove and it has a vent that goes out the ceiling and them out the roof but you can still feel the heat when you cook inside so I really enjoy the slow cookers. I like the idea of the solar cooker but it is a strech for me.... Good luck, Evelyn

      That's interesting. Does anyone on this list actually have a "cool roof"? We are about to buy a house and paint it 100% including roof with the reflective paint/coating. Any cautions?
      As to the oven, I have been thinking of some time about ovens and refrigerators that vent very well to the outside in hot weather, and then the vent is closed in cold weather - almost an indoor/outdoor kitchen, maybe with removable wall sections. Any ideas there? The oven and refrigerator would have to lie against outside walls, obviously.
      Another thing - how hard is it to deal with Houston-area homeowners associations when desiring to install solar collectors on the roof? Any tips?

      Is the vent going through the roof or the wall? Most exhaust fans have a "damper" which opens when the fan is turned on, it is also lined with a foam gasket to give a better seal when not in use (damper closed). There is almost always some leakage of outdoor air into attic (or wall cavity) being that the rough cut out is not sealed where the pipe exits. Since Ac conditioning cause a "positive air flow" (pressure inside the home greater than the outside) there can be some loss, sealing even your plug and switch plates on exterior walls with foam gaskets (big box stores), weather-stripping, caulking and insulation helps. How old is your home? Older homes like mine (35 +) are almost impossible to adequately seal. Good thing hot air rises and cool air sinks, the bad part is the pressure inside when the AC starts and is running. Maybe check with  http://www.building science.com/ dtw designs that work. Have not been to this site in a while, two years ago they had a comparison of model homes built for their climates. ASHRAE is also a place to look. Homes in Texas are very complicated. Being that you don't want to absolutely seal your home from outside air (stale air quality) but the hot humid air is the worst thing to contend with concerning air infiltration. Check what they are doing in Florida as well, as they have cool roof initiatives.
      On a side note we had purchased a new elect. oven (single oven) and noticed that when the oven was turned off the convection fan still ran pumping I'm sure thousands of unwanted BTU's into the kitchen area. Found out this is for cooling the electronic components (touch pad) when pressed for an answer the manufacturer told us MOST appliances are designed for a COOL climate!! When I asked them what they had designed for a hot humid climate there was a long and desperate lull in the conversation! ! Adding to the cooling load in the summer, more electricity, more $$$. I have been thinking about the offset in cost to use a remotely located exhaust fan (in-line) so when we cook the stove top AND the oven (via a tinned lid on the oven cabinet & duct) the exta BTU's will be forced outside at the same time. Whether this is cost effective is up for experiment, but it should help to keep the kitchen cooler in our summers when the AC is grinding away!!??
       Good luck and keep us posted!!

      I have a vent to the outside of the house for my gas stove. What would be the best way to keep all the air conditioning and heat from going out?
