Physical-Physical and Physical-Computational Testing of Daylight Systems

Sun lighting physics allows for partitioning between direct and diffuse components. The Daylight Emulator will capture the diffuse component, while the Heliodon will capture the direct component of daylighting. No scaling effect corrections are necessary. The Daylight Emulator and the Heliodon are readily reprogrammed using standard APIs realizing a diverse spectrum of daylighting conditions. The CUBE2.0 has been recently developed which will expand the capabilities of the Heliodon to capture the direct component refraction patterns of complex fenestration systems of a variety of types.

Light input from testing will be the input to computational models developed in general purpose software such as Radiance or custom software developed in-house. The computational analysis will output results directly with possible use of such output to control and adapt the façade properties.
