Dear all,

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.
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) and 2 Boilers (0.92 Eff.).

Although the efficiency of the selected HVAC systems is much higher than
the efficiency of the baseline model, the simulation results indicate
annual energy consumption of the proposed design is much higher than the
baseline!

Am I missing something or did something wrong in the models? Please see the
attached files of the both models

.
I would greatly appreciate it if anyone kindly gives some feedback on this,

Morteza
