This presentation showed the stages in a 8-month effort to model, generate and validate representations of a specular metal mesh for use in daylighting simulations in a large museum project in the desert. The mesh (which is manufactured for use in cladding and fencing, not a daylighting) is used throughout the building project, cannot be used to generate a BSDF simulation material based on physical measurement using goniophotometer data, and would not be modeled as a BSDF by its manufacturer. L+U presented the entire process of simulating the mesh, from studying the material, to developing a simulation material, to use in a variety of daylighting and electric lighting simulations at the building scale.
