Regular Occupied Spaces in an Animal Facility

Andrea, I don't think these spaces would be considered regularly occupied based on the LEED definition. If the human time in the room per day were one hour or more, and it sounds like that's not the case, then that would be different.

I have had reviewers specifically state that the amount of time spent in an area has nothing to do with it being regularly occupied. In this case, I would look more toward arguing for an exception based on use. In my one-time experience with animal labs, control over the animal's sleeping patterns, lighting, and noise were critical to the research being done and windows would impede this. Is this something that applies in your case? Or, you could argue that this is basically an animal storage area but because they need to feed and check in on the animals, that might be a harder sell.
