The only thing I would add is that people generally want to know where they stand and how they are doing. So if you have a benchmarking system in place, or if you can just do it within your own portfolio to find out if they're all consistent or if you have a couple of buildings that are real problems, there is instant feedback on performance. There is a little bit of competitiveness. There is a little bit of “I can do better, I can be the best, I can improve. Look at what I'm doing”. It's a feedback source that a lot of building owners and property managers want to know about.
I agree with Stephen's comment about the marketing department. If I can use that information as a marketer of space or marketer of buildings to get a better dollar for the space, I'll do what I can, and that information is very precious.
