Ceiling Fans




I've found people have often said that you want a fan to be blowing down on you in order to keep it running.  Well, this isn't always the case.  If it's cooler outside, having the fan blow upward toward the ceiling will cause air and heat to flow out through the roof.  It's not as good as having a fan blow up into the attic, which is doable, I've seen it, but this not being possible, having the fan blow up will cause a vacuum which will cause air to flow in from the outside.  I wouldn't recommend this though if it is already cooler inside than outside.

Windows: Building Envelope Improvements

So, I recently hacked some window coverings into the window that I found in a dumpster.  They were these large pieces of white styrofoam that I found in a dumpster.  I managed to fix the pieces into the window that only had those tinny aluminum mini-blinds.  My wife complained at first, but it was an improvement, and kept the heat out rather effectively.

We did end up getting curtains, and moved those pieces of styrofoam into the attic/crawl space to work as additional insulation.  Now everybody is happy.
