<DIV>Mehta/Demba,</DIV>

<DIV>Before taking the approach of increasing "the proportion of your space that benefits from daylighting as a result of the deeper light penetration allowed by the shelves," you should use a detailed daylight simulation program to determine if any extra credit should be attributed to your chosen light shelves. Though conceptual renderings and many designers tend to suggest there is great deep daylight benefit, most daylighting experts suggest the real benefits to be the reduction in direct solar radiation striking occupants and the fact that the bounced light dispels shadows/contrast areas on the ceiling near the window, enhancing the overall ambient lighting of the space.</DIV>
