Abstract

We present a generative tool based on a new simulation method for making sun- lighting an actual formgiver in architectural design. Our system reverses the common simulation process. It works with intuitive sunlighting properties such as " this area must be sunless the afternon in summer ". Given a property, it computes a complex geometrical volume figuring the sunlighting phenomenon in time and space. This volume provides a visualization of the sunlighting cons- traint and it enables the designer to model the different solutions — shadings or openings — that exactly check on the given property. We illustrate the system with two demonstrative examples in architectural design and we introduce some new developments under consideration at the present time.
