My factory project has cold storage (10oC) and a freezer (-13oC). For the factory, we use ASHRAE 90.1-2016 as normal but for the cold storage and freezer, what is the standard to set up the baseline? I heard about the "Energy Modeling Guideline for Cold Storage and Refrigerated Warehouse Facilities 2013" of the IACSC. I'm wondering if we have to use this guideline to set up the baseline or not. And In case we don't claim the saving for the cold storage and freezer, can we not use this guideline? like we just treat those spaces as a process load in ASHRAE 90.1. Thanks for your advice.
