Hi, I'm looking for an answer regarding credit SS 3 for a LEED Home. What documentation is required for the SRI? For NC there's a table which states the SRI of concrete being >29. There are no guidelines in the LEED for Home reference guide outlining what is necessary to obtain this credit. Any input is much appreciated. Regards, Jenn Whitney, EAPC Architects Engineers

Jenn, in general it's fine to use the guidance in NC when it's directly applicable, as it is here. That said, I believe the latest is that WHITE concrete has SRI >29, but not gray. Many paving products lack published SRI values. If you can find a material that is comparable in color and sheen that does have a published SRI value, it's admissible to use that value. Another alternative is to see if you can an organization that has a test instrument you can borrow. Here in Northern CA, I've been told there is such an instrument at our utility's tool lending library (PG&E's Pacific Energy Center in San Francisco). Your local utility may have such a service as well.

Ann, Thanks for the update. I'm looking into ways to test for the SRI. I found that we're in need of a pyranometer. I haven't found one locally yet, but plan on continuing to look. The Green Rater has informed me that I'm not able to use the NC guidance to establish the SRI of the material. He recommended contacting the concrete company. Thanks again for the input!
