Abstract
To enable students to evaluate the impact of light on the scale models of their architectural projects, two physical simulation systems have been built: a mirror box and a sun and sky simulator. Both devices integrate LED-based light sources. We have integrated several models for the computation of the sky image: luminance models and colour appearance models. The integration of the recent and evolving LED technologies explains how our simulators are innovative.
Highlights
At the School of Architecture of Strasbourg (ENSAS), teachers developed a lighting simulation activity with the objective of placing the students under experimental conditions and considering the issues of light ambiences [1,2]
The teaching feedback and the relevant exchanges between Belgian Building Research Institute (BBRI) and ENSAS technical teams led to the definition of the design and the technology involved in our simulators
We developed software able to compute the images of the sky, knowing the position and the address of each source, it is possible to consider our artificial sky as the display system for these images
Summary
At the School of Architecture of Strasbourg (ENSAS), teachers developed a lighting simulation activity with the objective of placing the students under experimental conditions and considering the issues of light ambiences [1,2]. Experiments were conducted at the Belgian Building Research Institute (BBRI) in Louvain-la-Neuve, in collaboration with the Climat & Architecture laboratory of the Louvain-la-Neuve School of Architecture [3] This pedagogical agreement allowed teachers to define their educational needs and to gain experience with the use of these simulators. The Strasbourg School of Architecture decided to take advantage of a recent building extension to develop its own laboratory made by two high-tech devices designed for experimentation, research and teaching purposes: a mirror box and an artificial sun and sky. Both are installed on the ground floor of one of the two buildings that make up ENSAS.
