Hi all, I am working on a major renovation of an existing downtown campus building. The entire roof of the building is being redone with white TPO. However, the existing elevator and stair enclosures, that pop up out of the roof, will remain the same not be finished with the white TPO. Can these elevator and stair enclosures be excluded from the roof measures area calculation, listed as mechanical or appurtenances?
Thanks,

Hi Julie, sorry for the delay.
In case it's still useful, I believe the pop up areas would need to be included in the total applicable SF and would not be considered mechanical areas or appurtanances.

Emily,
What about walkway mats that will be adhered to the TPO? The manufacuturer is telling us they do not need to comply and are not able to provide an SRI value. I am not finding these specifically defined as appurtenances in the reference guide or an Interpretation. Can anyone confirm? My gut says they should be compliant.

No, anything that shows in the roof plan and is not one of the qualifying areas named in the Ref Guide has to be included in your calculations. If it doesn't qualify on its own, you may still be able to meet the overall requirements, as this is a weighted calculation, so it will depend on what is on the remainder of the qualifying roof area as well as your site hardscape.
If the manufacturer does not have the info available, the product could be tested for the value. Otherwise, it's just treated as a noncompliant area.
