The energy cost offset from onsite renewable energy cannot be used to demonstrate compliance with the prerequisite. Can this cost offset still be credited to the proposed energy cost savings for this credit?

How to account for pressure adjustments when Multiple units have different MERV filters

Hi , I am working on a model in which the baseline is system 7 which means 1 system per floor, but the proposed system has different units serving one floor and they have different MERV filter ranging from 8 to 13, how to account for pressure adjustments in all the units since in the baseline we only have one system per floor and the zones in that system all have differnt MERV filters.

 

TIA

Rajat

Hi there Rajat, I think I would do a weighted average of each system MERV ratings' pressure adustment with respect to the systems' delivered CFM.

This is correct. However, note that MERV 8 filters do not qualify for a Baseline pressure drop adjustment.
