Southern "hot" cities more energy sustainable than northern "cold" cities?

Thanks for the informed critique of the article. Just as your seat-of-the-pance rough guess, do you think overall energy consumption for houses of equal net thermal exchange rate* between inside and out are generally greater in northern regions, less or about roughly the same as much more southernly regions? Or is there just too many unknowns for you to feel comfortable even giving a guess?
