Hi all experts,
I'm working on 4 cold storage warehouses which all the cooling source form one refrigerating planttoom, i guess i should consider it as the "district cold storage" , however i have not find any guideline to follow for the energy modelling, it would be nice to have some instruction on this.
Also, since this project has only one room (which is cold storage), that means on the energy part i'm simply only have "light" and "receptacle equipment" consumption, while i am pursuing exceptional method to get more credits, can i not model the refrigeration part since it will not influence other energy consumptions and it will be excepted. Is this the right way to think, or is there any other solution?
Thanks so much,
Ryan

I've had an experience at a project where it was one refrigerating facility onsite for two different LEED projects. So it was treated as an district source of cooling (actually, it was not only cooling sourse - it was thrigeneration/CCHP: electricity, heating and cooling).
The second thing - I understood it like "can I exclude this refrigirating building from energy modelling, since it's small separate building and provides only cooling services to other buildings". If such - than yes, you can exclude it, since it's separate building and can not be certified due to 0 FTE. Just be sure to exclude it from any other credit issues.

You must model the refrigeration portion of the project assuming it is within your LEED project boundary. You can model it separately and add the energy use to the model for the remainder of the project since there are no real interactive effects. To claim savings you need to use the exceptional calculation method. Here is an acceptable method for modeling the cold storage https://www.gcca.org/legacy-system/protected-docs/protdocs/EnergyGuideli...
