I would agree with everything that was just said. I'll break it down into two silos if I may. The first is obviously cost on the major retrofit side, and we've talked about that. The second is a little bit of misinformation on what we'll call the minor retrofit side.
I'll go back to 2009 when we brought forward to our members a program called the energy benchmarking program. Originally it was called 20 by '15, which was a target for them to meet 20 equivalent kilowatts per hour by 2015. That was at a time when we had very little idea of what each building was doing in terms of energy performance so there was a lot of fear out there. What they found was that through minor retrofits, through lighting, through turning off computers, through timed power turnoffs throughout the night, a lot of these targets were achievable at a reasonable cost.
