We are working on a Hotel project in Sri Lanka and planning to obtain LEED certification for the facility. Hotel is to be constructed as chalets and the project team has decided to use red color clay tiles for roofing.

The roof is a high sloped roof and the use of a roofing material with a SRI of 29 or above would meet credit requirements.

is it allowable to use the reference SRI value mentioned in the LEED guideline for Red Clay tiles as there is no testing facility available in the country to certify the SRI value of the product?
