In Germany and some other parts of Europe, they have started building "passive houses," houses which take almost no energy to heat due to careful design in ventilation and insulation. Plus, it does not cost much more to build. However, it is unclear if such houses would work to stay cool as well. Otherwise, it will not be very useful in most of the US, not even Boston. The article also mentions that many things such as the glass for the windows are not available in the US. I wonder if there is some patent barrier on it or something or maybe it's simply not made in the US.
Perhaps these people would be good for our talk.
