That's a very good question. As we indicated, we were obviously trying to make a very energy-efficient building, but it was also a green building, and green incorporates many more things. Thomas alluded to those in terms of good day lighting, good indoor air quality, and so on. Obviously, we designed those into the building, but, then, of course, the question is, how successful were we?
There's a group out of the U.S. that's called the Center for the Built Environment, part of the University of California, Berkeley, and they have developed an occupant survey. It's a set of standardized questions. They have hundreds of buildings across North America that have taken that same survey. It's an online survey. The occupants of the building take the survey, and all the results go to this group at the Center for the Built Environment. Then they analyze them. It's the usual type of question such as, “How happy are you with the lighting in your building?” The answers range from very dissatisfied all the way up to very satisfied.
We did that for our building, and then they give you, on a scale of zero to 100 percentile, where you fit relative to all the other buildings. In our case, out of, I think it was, eight different categories, we were in the 95th or higher percentile for all of those categories. In fact, the only one we were low on was acoustics, and that's a separate discussion we can have, but overall, when they took our building and compared it to all of the buildings that had gone through that survey in all of North America, our building came first in North America in terms of those occupant comfort and satisfaction issues.
