If pursuing this credit only, not 5.1 or 5.2, does the vegetation for a green roof need to be native/adaptive. We would like to use an extensive or ultra extensive roof with sedums and grasses, which will eliminate the need for permanent irrigation, but are concerned that these will not be compliant.

I would say you are correct that you don't need to use native/adaptive plantings.Because there is this conflict between sedums as the common green roof planting and the native/adaptive requirement for SSc5.1, I'm curious if anyone out there has had success using sedums and earning SSc5.1?

You are correct. We were just approved for this on a recent review. Our project was not going after SSc5.1 but did use the vegetated roof to qualify for SSc5.2. The roof uses sedum plants which are not native here in Virginia. We were approved for both credits plus an Exemplary Performance credit in SSc5.2. Go for it!
