Dear Forum,

I am modeling a building which has no heating or cooling system in the design, so, according to Appendix G, I have modeled these systems exactly the same as in the baseline design. My problem is that I don't know how to calculate the pressure drop adjustments (A), since it says in table G3.1.2.9 that you should use the values from the proposed building design, but since there is no such design, what devices should I include from table 6.5.3.1.1B?

I am modeling HVAC System #4: PSZ-HP.

Many thanks in advance.
