We have an art lab which has a ton of equipment/machines that students use for metal working/ pottery/ etc. It would be very difficult to get this equipment to meet surface reflectivity percentages. Do we have to count the equipment/machines? Technically they are work surfaces as students are working on them to make pottery, molds, etc., but we can't alter them in anyway to adjust the reflectivity. If we just count the walls, ceilings, built in counter work surfaces, and other furniture could we still make this credit option?
