Regarding cooling, I wanted to add to the list of possibilities. We have concrete floors with radiant heat installed. What I wasn't expecting was the effect that this would have on keeping the house cool in the summer. The floors have a great deal of thermal mass and contribute greatly toward cooling on hot days (it gets over 100 degrees for several days every summer; days in the 90's are common). (We happen to have a southern orientation and in the winter the sun warming the floors helps warm up the place even without turning the heat on.)
