Right. It sounds very worthwhile. Thanks for the information.
The BOMA ladies, if I could just switch over to you, what is the best way to measure a return on investment, in BOMA's view?
The reason I ask is that the government has done target buildings on a plan to test out the program. We've gone back a couple of years after a building has been upgraded, and we've looked at the cost and the energy usage. There's no direct correlation between past energy use and post-upgrade energy use for any of the buildings that have been upgraded.
Before the government rolls out this plan to upgrade all the buildings, what is the best way to measure the return?
