[Greenbuilding] Natural ventilation

[Mark Marcoplos]

I use natural ventilation (as well as some fans) in our house which I 
designed. It works great. We have no mechanical air conditioning, just a 
whole house fan that we use sometimes. The house was designed to passively 
cool and thus relies inlarge part on natural ventilation. My web-site has 
some info on it and a link to an article I wrote for Smart Homeowner 
magazine on passive cooling,

We are in a rural area so the air we encourage to flow through our house is 
clean & fresh. The benefits are many - fresh air, natural cooling, little or 
no electrical use, less moving parts to need maintenance, and connection 
with the outdoors.
