Onsite Renewable for 1% of owner controlled annual energy cost.

Hi Marcus, I've recently been asked if we could prorate the "1% renewable" to account for only the owner controlled annual energy consumption cost rather than the total building annual energy cost. My answer was no, it must be 1% of the total building annual energy cost which includes both owner and tenant controlled annual energy costs. I am pretty confident in my answer but wondering if you had anything to add. Thanks again for all the expert energy advice you provide throughout this forum. Dave
