This program uses the standard Zonal Cavity method to calculate average light levels in a room. You can see from just one screen many different things: change the wall color, or the color of the carpet or ceiling tile – and see how the light level is affected. You can try out many different types of fixtures and lamps too.
How to Use This Program
The RCR, “room cavity ratio,” is a function of the dimensions of the room. This is for commercial buildings, so the 19 fixture types are all commercial luminaires that are recessed in the ceiling grid.
