Greetings,
Currently I’m working on a building extension pursuing a LEED BD+C New Construction, the IN- Heat Island Mitigation with Cool Walls credit is being attempted, although some issues have surfaced. Sherwin Williams paint was used exclusively to cover the walls, but this manufacturer has no information on the RI and Thermal Emittance paint values. Does anyone if it is possible to achieve this Pilot Credit through a comparison of the paint used in the project with a different manufacturer, like Berridge, that does have said paint values?

I’d be grateful if anyone share information on cases similar to this one,

Hi Jorge,
I have a similar issue but found that Sherwin Williams offers a range of exterior pigments with higher reflectance than standard paints, even for darker surfaces. However, these colors are currently limited to six shades: White, almond, blue, red, gray and copper-like. On their website, you can find a brief description of how these colors behave, as well as their Solar Reflectance Index and Thermal Emittance. Also, you can find some study-cases and results of other LEED projects to which these pigments were applied. This information was useful for a project in Cd. Juárez, México.
Please let me know if you found another solution for your issue since it would be helpful for us to have more options to offer to the different contractors involved in many projects.
