I live in Seattle and in the summer we have a few weeks of warm weather but nothing extreme. Most people don't have AC, including me. People use open windows, celing fans, attic fans, skylight ventilation to cool things down during the 3 weeks of hot days.
Our house has one zone of that has a trunk that goes to the attic and blows down on rooms and the other trunk goes to the crawl space and blows up in rooms.
It has been suggested that I add an attic fan to clear out the hot air from the attic. Why couldn't I put a large motorized damper to route the air from the furnace (while in fan only mode!) right into the attic and out the ridge vent. Basically this would pull the air out of the house and clear out the hot attic, without needing a second fan and all of the associated systems.
An alternative idea would be to suck air from the (cool) crawl space and push the hot air out of the house. This would be a little tricky as it would have to control the return air from the house to the crawl.
I'm assuming that I could use the automation system to look at crawl, house, attic temps and do the right thing based on temps.
Where is the flaw in these ideas?
