Vats in winery's production area

Hello, in daylight simulation you should use regularly occupied floor area. First of all you should consider, if this space should be included in the analysis according to 'regularly occupied space' definition. According to USGBC, "Regularly occupied spaces are areas where one or more individuals normally spend time (more than one hour per person per day on average) seated or standing as they work, study, or perform other focused activities inside a building." Some examples are private and open offices, conference rooms, break rooms, and lunch rooms. I suppose wine vats don't meet the definition.

Depends on if there is focused "work" done on the vats or their contents. Testing? Writing up reports?  And at what frequency. I would think the actual footprints of the vats can be discounted, but you probably need to explain what activities occur in the space.
