How the inverse lighting methods could help the architectural design? We address this issue with an original light-based parametric design model dedicated to the architectural design. This model associates the parametric design approach with the lighting intentions expressed by the architects. It has been implemented thanks to an inverse lighting technique in a tool intended to aid the design of the windows and the shading devices in the early stages of architectural design. This model is used in a performative design approach onto the dome of the Louvre Abu Dhabi museum in order to define the transparency property of the dome.
