Dear Everyone

I have a question regarding to cooling in electric room such as transformer, UPC room or electrical switchboard room. I use Carrier HAP for LEED modeling purposes for projects loacted in Poland. That spaces are often located in underground floor near parking garage. Technical description says usually that temperature must be max 30C or max 10 C above exterior temperature in cooling time. Sometimes it is hard to obtain any information about thermostats.  Sometimes cooling occurs only in emergency conditions. 

There are 2 cooling types usually:

1. They are cooled mechanicaly using split AC.

2. Exhaust fan operates only if temperature is too high and cooler air is transferred into space from unconditioned garage area.

My question is if we need to model that cooling process, or can we neglect it. If yes how to set a heat production of these electric units ( power and schedule), because it is hard to predict how they will behave even if we know specific device. I hope that energy use of that equipment such as electricity loses in transformer should not be included in building cost. In Baseline I suppose that System Type 3 should be used in such cases.

I am thinking to include that spaces into "Unconditioned". Previously I set spaces as conditioned, but they operates without any miscellaneous loads so instead of cooling they functioning as heating devices. 

Many thanks for any help.
