I have an existing metal standing seam roof that is historic and will remain, and there is a new skylight going in. How do I calculate the heat island impact under LEED v4 New Construction with these two features? Also, do I need to have the existing roof examined to get the actual SRI from it?
Thanks,

Hi Jonathan. You will need to have the existing roof tested to get the actual SRI value unless you have existing building documentation confirming the manufacturer listed 3 year aged SRI value for the material. The skylight should be excluded per page 200 of the LEED v4 Reference Guide.
