We are pursuing this credit as a pilotcredit for a Core and Shell project of a datacenter. Considering the limited share of glass and/or other materials with a high reflection factor, it was relatively easy to obtain this credit. 

Nevertheless, it was difficult to find the right threat factors for the materials used. Moreover, these seemed to be different for different sources. Is there a database available somewhere that prescribes LEED or that provides a good basis for performing the calculation?

I can imagine that this can help in other projects. 

Thank you in advance!
