Hmm, I remember we had a great big exhaust fan at the top of a stairwell in the victorian monster I grew up in (holy crap, no wonder my dad drank whiskey and listened to Janis Joplin when he paid the bills). In the house I co-own now, which is two stories, 1400 s.f., the previous owner installed a sizeable skylight in the ceiling at the top of the stairs. We leave this open as a hatch for hot air, but there is no fan associated with it. We could possibly put a fan in the attic and leave the stairs pulled down as an extra air-draw, but I think the skylight working as a kind of chimney might be the best combination of effectiveness and passivity, not to mention aesthetics -- the skylight is beautiful, open or closed. I don't know. Ruediger's ruminating on it as we speak.

Hi LJ. Whole house fan is a high velocity fan that you install into the ceiling of you upper most floor, usually at the top of the stair ways, but anywhere in the hallway. It draws the hot air of the inside of your house into the attic. You leave the windows open. As the hot air is drawn into the attic, the cooler air from outside is drawn in. For places like Seattle, it's a great and less expensive alternative to Central AC.

It's not as unattractive as it looks on the site. That's the view from above. From below, where you'll be, you'll just see the vents slats.
Sarah, I think the skylight as a chimney is a great solution. In theory it can work like the Glass Dome of the Reichstag in Germany.

The Glass Dome is created not only to provide natural light to the building, which today functions as Germany's Parliamentary center, but the dome creates airflow by heating the air within the dome which then flow up, drawing the air out of the building. Cooler air outside is drawn in through the lower levels. When the vents are shut off, the heated air serves to heat the building. I wish this kind of thought is given to new homes, where air flow can be created passively instead of relying on electrical appliances.
*edit to change links for whole house fan. I originally had a link to Home Depot, but dynamic links, kept changing what you'll actually see. so I found one better.

Neat, Nipith!
Those kwazy Germans.

Thanks for the link/info Nipith. I'd never heard of whole house fans before. My house has cathedral ceilings in the living room/stairwell so I am not sure one could properly be placed. And, as you know, so far Seattle is still pretty immune to many hot days - we had 4 days of mid - upper 90's but it is now back to the pleasant lower 70's. (I'm wondering if 4 days in a row broke some kind of record! ;) ).

Whole house fans are common in many homes in Connecticut. But now that some new homes are being built with central A/C you see it installed less.
The fans work great if the outside temp is cooler than the inside. Such as the evenings. But here in the North East, our Summers can be very humid even at night.
Those fans are useless when the air outside is as hot as it is inside. Then ya just blow around the hot, humid air. Yeck.
Todays small window air conditioners are very quiet and efficient. I'm sure the two small ones I use are more efficient together than the one old Der Blitzenator model I used to use.
Oh, and to conserve energy....I recommend showering with a friend. ;)
