I'll add something to the comments you've received so far in your question. The work we did in the early 2000s for Public Works, that was done for their technology directorate. I don't even know if it exists any longer. I do know that we always wondered why there wasn't any implementation following some of the work we had done. We later did it for retrofitting existing buildings, too. There was another study done at that time. They're dealing with real estate division, I guess. There is some difficulty there, maybe, taking some of the ideas and putting them into effect.
