Projects that provide covered parking are eligible for points under this credit, but what if a project provides no parking?

Should I use the SRI value of new or weathered concrete for my project?

What is hardscape? Is a gravel surface considered hardscape? How about artificial turf? Wood? Tennis courts?

Nope....we currently have a call into the supplier that we are specifying, but we havent been able to find the SRI value. We are thinking about finding out the permeability of the product. Good luck. If we find something out in the next few days, we will let you know.

Thanks. I did read in a comment somewhere that it may be exempt if it's 50% of more pervious, but couldn't find that in the reference guide. I'm definitely interested in whatever info you get!

Hi Ema and Amy, have you had any luck finding the SRI value or pervious percent of decomposed granite? We have a countryside project and all hardscape are made of this material. Thank you!
