We are trying to classify a winery. One of the areas is used for barrel fermentation, and is temperature controlled anywhere from 55-75 degrees based on the fermentation process. Would this count as un-refrigerated warehouse space? We believe that it should be Other based on the fact that it is production space and has a higher energy usage than a typical un-refrigerated warehouse.

Second, we have a large space full of tanks for different fermentation processes. These spaces are unconditioned as each tank has its own insulation and temperature control system. We do not believe that this should count as unconditioned space because that does not reflect its actual energy use in any way. Would this fall under Other, general warehouse, unconditioned space?

Thanks,
