Do I have this correct? A tenant space in a multi-story building wouldn't have to have walk off mats. If they don't do high volume copying and have no chemical use, they don't have to have separate exhaust. If the building maintains the toilet rooms outside the tenant space, there is no janitor's closet in the tenant space. The only requirement to obtain the credit would be to use MERV 13 filters. Seems too easy. What am I missing?
