This method uses the reflectance coefficients of room surfaces to model the contribution to useful illumination at the working level of the room due to light reflected from the walls and the ceiling. Simplified photometric values are usually given by fixture manufacturers for use in this method. The Zonal Cavity Method is used as a basis for both hand, tabulated, and computer calculations.
