Heat Island Mitigation with Cool Walls

  Hi Nohemí, My team recently found that Berridge offers a wide color chart with all the information needed to document the solar reflectance (SR) and thermal emittance values for the Heat Island Mitigation credit. They have several products available in Mexico that meet the LEED requirements. It might be worth checking out their offerings to see if they suit your project needs. Best of luck with your certification process! Best regards,

Berridge is pretty good indeed

Hi Nohemí, 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 materials work, several case studies from the company, as well as the Solar Reflective Index and Thermal Emittance for each of them. You might want to contact them directly for more information on colors beyond those listed on the website. Good luck on your sustainability journey!

Sherwin Williams offers a range of exterior pgments with higher reflectance than standard paints, even for darker surfaces. However, these colors are currently limited to only six shades (white, almond, blue, red, gray and copper-like). I think that you can find a brief description of how these paints work and as well as their MRI and ThEm values in their website. Please let me know if you find any better options or solutions since I'm also looking for the most efficient pigments to comply with the credit.
