 It can be a little bit more. And what I hear from all the experts in the field, since I'm not an architect myself, is they always are adamant it doesn't have to cost more. Because, for example, when we used to build houses that were full of cracks and holes, they would put an extra large heating and cooling unit because some of it was being wasted. So if you have a nice, tight building that's built properly, you can put a smaller heating-cooling system, which costs less. So there are ways to balance out the costs.
