Hello guys.
I am modelling a hotel for LEED purpose. I need some help to chose the right table to calculate the Minimum Efficiency Requirements
My system is package terminal heat pump PTHP (system 2).Which is the correct table to calculate the HVAC efficiency? 6.8.1B Electrically Operated Unitary and Applied Heat Pumps or 6.8.1D Electrically Operated Packaged Terminal Air Conditioners, Packaged Terminal Heat Pumps.
Thanks.

Hi Oscar,

I would most probably use the one that reads "Packaged Terminal Heat Pumps" in its title (6.8.1D). Specifically, reference the "PTHP" rows therein ;).

Thanks Nick

The problem is that if I use that table my base line is less efficient.
At this point I can get or fail the prerequisite so I want to to be 100%
sure
