The parking lot is shaded by the building for much of the measured time, but the building is not "an architectural device(s) or structure(s) that have a SRI of at least 29". So, does that mean that this credit is impossible to achieve even though the parking lot is situated such that it does not contribute to the heat island effect? Since the building and the hardscapes are treated by two different credits (7.1 and 7.2), it seems unbalanced to "ding" the parking lot for the builiding's low SRI.

If we planted trees in between the building and the parking lot, then a model would show credit-achieving shading, but in reality it would do nothing to reduce heat island. I hate even discussing such a wasteful point-hunting strategy, but I'm testing my understanding of the credit here (and, yes, whining a little bit about the potential silliness of this).

Does anyone know if there is a good, high SRI coating that can be applied to EPDM (years after initial roof construction)? If such a coating were applied to the building roof, then would both 7.1 and 7.2 be achievable in this case?
Thank you.
