In LEEDv4, the Surface Reflectivity criteria was measured by using "area-weighted averages", thus the Interior LIghting Calculator asked for areas of walls and ceilings. One big compliant area could make up for a lot of smaller non-compliant areas. There is no updated calculator for v4.1 and the Surface Reflectivity criteria calls for only for "at least 90% regularly occupied spaces...". Therefore, do we simply list our regularly occupied spaces with LRVs and count to see if 90% of our spaces comply, no areas needed?

Hi Tim,
here tou are a clarification from reviewer:
"Strategy 3: Surface Reflectivity
1. The required documentation has not been provided.
Provide a list of surface materials used in the regularly occupied spaces with a description of the surface, manufacturer or
vendor name of surface (Optional), surface location, reflectance value. Average surface reflectance values (surface area
weighted) may be used if all surfaces do not meet the surface reflectance values required."
I think this wil be useful for you!
