Abstract : This research project deals with an inverse lighting model taking into account daylighting in architectural project. Our goal is to propose a digital method to assist ``design by ambience intention'' which is close from parametric design. Our work focuses on incident light coming from sky vault and urban surroundings into the designed space.

We propose a method which concretizes lighting ambience intentions, by producing geometrical properties of openings. In first place, our method materializes lighting ambience intentions in a digital scene, with a photometric rendering and graphic descriptors. By using these descriptors, the designer is allowed to express his lighting ambience intentions through physical lighting parameters.

An inverse lighting model uses these physical parameters to compute opening shape and size. Inverse lighting problem is seen as a source emittance research problem. An image comparison between source lighting and intended lighting allows to evaluate sources properties, and therefore to define building openings. This model is checked through opening reconstruction in test cases. Confrontation to real situations shows integration possibilities of our model in architectural design.
