Inquiry

Our project\'s operational requirement mandates large paved areas in excess of 30% of the 490,314 s.f. site area. Our goal is to specify a previously developed concrete mix that complies with ASTM C1549 and has been previously tested and presented to USGBC on a prior project. The test results for this material yielded a Reflectance Average Value of .41 for the concrete paving material. The previous test results on three concrete pavement samples ranged from 0.38 to 0.45 Reflectance (Albedo) Values. The testing lab that conducted the reflectivity testing for the prior project has the following accreditations: IAS-ES TL-189, State of Florida TST 1556, Metro-Dade 01-0727.03, and CRRC. This C.I.R. is requesting confirmation that USGBC will accept documentation certifying that the concrete mix utilized on our project is equivalent to the previously utilized and tested mix and that actual laboratory testing will not be required on a project by project basis.
