As the summer heat approaches, I wonder how our little townhome is going to fare with regards to the internal temperature. We discovered early on in the winter that the central heating unit, while maintaining a comfortable temperature, also wore a nice little hole in the bank account with the energy it consumed. Now that mild temperatures are the norm, the electric bill has dropped $80 on account of the unit being off. This is obviously a good situation for all involved and I would like to continue minimizing my consumption of power. So how does one stay cool? I want to add one of these to my place but I don't think the property owners would be too happy. I also think I would regret the decision when temperatures dropped below 50 or so. Still, the next time I'm living in a desert-like ecosystem, I will be adding a windcatcher to the homestead.
