Hi!
Currently, I'm working on a warehouse's project under LEED certification. There's no heating/cooling system in the warehouses, there's only natural ventilation.
In the building simulation, I dind't include any cooling/heating system and then I made some comfort evaluation and there are many discomfort hours.
Should I include any cooling/heating system for the discomfort hours, or the concept of unmet load hours are only applicable when we talk about conditioned areas?
Should the energy cost only consider the other uses?
Thanks!

You do not have to include a heating/cooling system in an unconditioned space. The unmet load hours do not apply to unconditioned spaces. This would be the same as an unconditioned parking garage. Assuming the warehouse is part of the LEED submission, the energy cost must include all energy use within and associated with this space including lighting, plug load, process loads, ventilation, etc.
While this only applies to heating only systems you might want to check out Systems #9 and #10 from Table G3.1.1A in 90.1-2010.
