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?
