Hello All,

I have modelled a 181,000 sq.ft building in Toronto. The building is
geothermally heated/cooled with zone heat pumps. Fresh air is provided to
the corridors by a MUA. Fresh air is cooled by DX coil and heated by
furnace in the MUA. Temperature is set at 70 F. The energy consumption
analysis shows that consumption of heating energy is same during the summer
months and the winter months for the Make up Air unit. Can anyone suggest
any possible reason and solution to this problem? Thanks.

Regards,
Hassan Quazi
