Big request for BAS - give us one std, don't change it. With arb number of levels and shapes - a square or triangular power load - guarantees no national market. Low level - EnergyStar Climate - Green, Yellow, Red as stds for all to support. Prob should have a blue - charge it now. Even aimed at home, more than the ES Climate 2 should be our default.
TC input to them for approp levels. So a big request of facility automation systems is "give us one type of levels"
