Abstract
The exact daylight simulation is quite difficult even now in the practical field of architectural and lighting design. The sub-working group on daylight simulation in Architectural Institute of Japan was established in 2003 to find solutions for that situation. This working group has three sections: a benchmark group, an interface development group and an evaluation group. This paper will introduce activities of the interface development group and the benchmark group at present. The interface group is now developing the input/output interfaces for daylight simulation programs, and the purpose of the benchmark group is to evaluate the accuracy of software. Geodesic Dome is applied for daylight source as input interface and a test case for evaluating accuracy of inter-reflection calculation.
