Luminance Imaging Measurements for Facades with Asymmetrical Light Reflection

Résumé

The subject of the research is to reduce light pollution produced by architectural lighting, by decreasing the luminous flux reflected to the sky but without diminishing the visibility of facades at night. The paper is a continuation of the authors’ previous papers, which showed that a facade with asymmetric reflection can be obtained when using only ordinary materials with diffuse reflection. The method consists in the use of horizontal decorative micro-profiles, with dimensions that are easy to achieve technologically. The optimization of the geometry of these profiles is the objective of this paper. For optimization, generalized modeling of light reflection in MATLAB is used, through original scripts. These scripts also automatically generate the mesh necessary for the discretization of the facade, for profiles whose angle is modified for the whole range of technologically feasible values. Based on numerical simulations, an optimal domain is identified, based on which the experimental program of effective measurements of the luminance of the facade is optimized, by using imaging methods.
