I’ll point out that certainly in the way we assess energy efficiency activities, LEED tends to be more in the construction of a building. Once you're achieved that standard through all aspects of the construction process, at whatever level, that's where it begins and ends. BOMA BESt then takes over as a measuring device for ongoing building maintenance. You can take a LEED building at any level and say, “Okay, we've achieved it; there it is”. But sure as anything, as time goes on, the efficiency of that building will slowly deteriorate. It's made up of a number of small activities that get adjusted or don't get adjusted. So what we've done is to put the two together.
Use LEED when you're trying to build it and get it up to standard, so you've got the infrastructure and the leading capacity in the building, and then use the BOMA BESt yardstick to measure ongoing maintenance, to do the retrofits, to do the smaller adjustments. Somewhere in our literature I'm sure you've seen the acronym DABO. That's a diagnostic agent for building operations, a piece of software that goes in and makes tiny adjustments every 10 minutes and keeps the system at the LEED level rather than allowing it to deteriorate and your having to go back with a major retrofit. They are two different standards for different purposes.
