Hello: I live in Maine No need for cooling here at any time of the year.Unless you weigh the same as all the others. "Tater fed oxen is the size of Maine women. But not me :) If anyone could tell me how much solar heat could be gained by painting the sunny side of my house black I would like to hear. A 75 X 14 Mobile home sunny side is on the back where nobody can see it. So I could do black paint. Thanks to you with knowledge, LL

You have a point that there will be some loss of heat in the winter, and probably a slight increase in heating costs, but the effect will not be as great in the winter as the summer. Shorter winter daylight hours with weaker sunlight mean that the heat accumulated by a dark roof in the winter is not as substantial as that accumulated in the summer (think about the difference between getting into a car on a sunny winter day versus a sunny summer day). There should still be a net reduction in energy costs, especially given DC's propensity for very hot, sunny summers and relatively short, mild winters. Also, Chu has noted the effect that this could have on global warming directly, reflecting heat back into space and reducing things like the urban heat island phenomenon. Overall, the benefits outweigh the costs, and that becomes more true as one moves south.

True but what about heating costs in winter? The oposiste must be true.
