We are pursuing the credit by covering 50% of the parking places with a white polyethylene shade cloth of 70% density. The project is outside US, and we don´t have shaders labeled with SRI values to use as reference. We are sure the material comply with the credit requirement, but we couldn´t find a similar material as reference in the web. Its there any page were we can find a SRI value for a white polyethylene mesh?

The exact SRI value will not be informed because we do not have the meas to make the analysis, but we suppose that the reviewer will know that this kind of material is good enough. If we present photographs of the shader cloth it would be enough to comply?
