This is a multifamily mid-rise building, 9 floors above grade. Per ASHRAE Table
G3.1.1A the Baseline HVAC system is system 1 (PTAC with hot-water fossil fuel
boiler) 9.3 to 11 EER. <br>
Selected HVAC system for the proposed design is WLHP (3 Ton High efficiency HP
by Daikin, 15.9 EER and 4.83 COP) with 2 cell cooling tower, DOAS unit (9.8 EER)
