Just replaced a 50-year-old tar/gravel roof with white shingles. This is in Florida. But now the house is hothothot, heat keeps rising, air-conditioner runs constantly but can't keep up! It's just after noon and 84 degrees in here! The roof is low-hip, the attic is a crawl space insulated to about R-30, there's a turbine on the roof and three passive vents. Still hot! Depressing after writing such a big check. Capable roofer says previous thick layer of tar/gravel probably insulated a lot. But now what's my next step? 1. Would a white latex coating be more cost-effective than a solar-powered vent? 2. Any other suggestions? Whew, and thanks!

My apartment's back exit has a windowed door (similar to this
, although it's only a single door) and no storm door. It's drafty and I'd like to insulate it as much as I can, sans
all but the most rudimentary carpentry skills. What's my best temporary solution? [more inside]

I'm renting a flat and it's cold, and it's going to get colder (I'm on a 1 year contract in the alps). Is there anything noninvasive (preferably cheap, but I'm ok to spend if it's really going to work) that I can do to warm the place up? What sort of portable space heaters give the best performance for electricity/gas? Are there any decent renter-based guides to improving insulation? [more inside]

Is leaving the windows in my attic cracked beneficial for keeping my air conditioning bill low? [more inside]

I want to seal off the staircase to the third floor of my home to save on heating bills this winter. The rooms are used for storage only now. Is bubble wrap a good insulator? I would like to let light thru but keep the heat in. My home is an old Victorian with a winding staircase.

Our 1200 sq. ft. partially finished basement is cold. There is insulation in the ceiling, and the windows are pretty new. Our thermostat is upstairs, so when the upstairs is comfortable, the basement is about 5-10 degrees cooler (a guess), even though there are heating vents in each room.
Can I just hook up a squirrel fan and pump warm air from the ground floor downstairs? Cut more vents in the ducts? Any other possible cheap/simple solutions?
I get the gnawing feeling that I'm stepping into a complex feedback loop problem--if I install a second thermostat, then the two thermostats duke it out until one of them wins or becomes skynet. Bonus points if you can point me to a place online where I can ask these questions and not get my head ripped off by HVAC professionals.
