less reflective roof surface desireable

I contacted GBCI to be sure (trying to get any points we can), and you were right. Here's their response; figured I should post for anyone else looking for official guidance: "It is understandable that not every credit is applicable to all projects. If the project conditions dictate a certain type of roof and/or non-roof material that does not meet the credit requirements, than this credit is likely not achievable. A vegetated roof is another possible option, though understandable if that is not appropriate either for the project conditions. It is laudable to minimize the amount of energy use for the building which will help with points in other credits; however, the intent of this credit is more about the immediate effect the selected roof system has on the 'heat island'. The Behind the Intent section of the v4 BD+C Reference Guide reads in part as follows: "Dark, nonreflective surfaces used for parking, roads, roofs, walkways, and other hardscapes absorb the sun’s warmth and radiate heat, creating heat islands.""   So in short, nope.
