Whe have problems to get SRI-values for parking deck coatings. Sto says on their website that the Light Reflactance Value (LRV) can be used to calculat the SRI-value. Has anyone documented the SRI-value based on the LRV and was that accepted by the reviewers? From http://www.stocorp.com "Sto's Color charts list the % Light Reflectance Value (LRV) of each color. This value (divided by 100) may be used to calculate the SRI for a given color."

My understanding is that LRV is used for measuring visible light (and is relevant for interior design), and SRI is used for measuring solar heat, including non-visible wavelengths. Converting one to another simply by division is not possible. I would ask Sto Corp to verify how they convert one to another.
