For the Advanced Rooftop Controls UES Planning measure, estimate savings as if X% of the RTU's would have operated with the supply fan in "auto" mode in the baseline. In the Research Strategy, ask about pre-existing operation of the supply fan: % in auto mode 1-day prior to measure, 2 weeks prior to measure, and 1 year prior to measure installation. Direct CAT to look at available data to help with determining X.
