Hello looking for any help on this. It is nearly impossible to find Manufacturer information for DG (decomposed granite) walk paths. We have installed DG walk paths and area of planet space with DG base. The DG if very light and should have a moderate SR value. Has anyone been able to find documentation to verify or at least support a moderate SR value claim?  Secondly; The language is incredibly vague and confusing; USGBC really did a poor job in many credits in v4. In several areas the language in the guide talks about vegetated planters and existing plants and or vegetation installed prior to occupancy as contributing to Non Roof Measures. Yet a review team rejected our project claims of vegetated areas (NOT TURF). GBCI seems to be taking liberty and arbitrarily interpreting left and right what is and what is not compliant. Has anyone submitted vegetated planters or on site landscaping (Not Turf) as contributing to heat island reduction. Scientifically it does so why can it not be claimed???
