CS-2009 EAp2:Minimum Energy Performance
Dear sir, Our LEED review of EAp2 said that the minimum efficiency for the Baseline Case PTACs should be 9.3 EER. I cannot understand it clearly and find the corresponding terms in 90.1. According to table 6.8.1D in 90.1,the minimum efficiency of PTAC(cooling mode) is 3.66-(0.213*Cap/1000)COPc. why should it be 9.3 EER?
