I am working on a cold storage project going for LEED certification , I am not able to understand the modelling procedure for the refrigerated spaces in eQuest.

The project has a built up of 1,35,000 sq. ft. out of which 89,913 sq. ft. incorporates refrigerated areas. I googled all the guidelines for cold storage energy modelling and followed the one by IACSC. The guideline was helpful but I was not able to understand the modelling of systems for the refrigerated areas.

Any suggestions on how shall I proceed ?

Thanks
