Data Sheet or Laboratory test report?

Hi Samer, you can provide manufacturer documentation.

Hi,

We have a project in Alula, were landscape team is using all natural material for paving. The team is not able to produce test report for the SRI values of the materials like natural stones existing on site, sand, gravels, boulders and rammed earth. Is there any alternative like RAl color card reflectivity values or other research papers providing SRI values of natural materials.

Also since the intent of the credit is to reduce hardscape area and retain the existing terrain, since the project is using all existing material do we need to show SRI values.
