I am trying to correctly determine the baseline system for my LEED energy model. I have a 7-story hotel building so it will either be System 1- PTAC or System 2 –PTHP based on ASHRAE 90.1-2007.

We are using heat pumps for domestic water heating. (The water source will be from the campus/district condenser water system.) Can we take credit in the energy calculations using heat pumps?
