Comparison of radiosity and ray-tracing techniques with a practical design procedure for the prediction of daylight levels in atria

Abstract

Designers are often facing prescribed requirements concerning daylight in atria. For the accurate prediction of the illuminances the designers should employ either computer simulations or apply empirical equations. This study compares results obtained by a practical design procedure and simulated results using Radiance and Lightscape 3.2. (C) 2003 Elsevier Science Ltd. All rights reserved.
