Hello! We have a project in which the client will install a roofing material with an SRI value of 70 (low slope: requirement-78) for 100% of the roof area. Can this be compliant with this credit, using the weighted calculation? Even though 100% of the roof has an SRI value lower than 78? Thanks!!!

Rosamaria, run the calculations and find out! There is a calculator in the Doc Toolkit above.

Thanks, Tristan. Yes, running the calcs and using the formula, it passes. But the question was more if this formula applies to a project where all the roof areas will have the same material with an SRI of 70 (when it should be 78), or does it apply only to projects where they have SEVERAL roof materials and one or some of them DO have SRIs higher than 78, and others don't? Thanks! :)

Yes, it applies.
