We are trying to specify ceilings with at least 85% surface reflectance. However, there are areas with metal ceilings that have perforations for acoustical and fire requirements. Can these open areas of the ceiling be ignored for the credit? In some cases the open areas are 30+% of the ceiling area, and behind it is a void area where the light would get lost. From a technical standpoint, these holes do not reflect the light back down. However, the physical drop ceiling surface (metal panels) are painted white.

Does this comply with the credit?
