Heliodon is a device for adjusting the angle between a flat surface and a beam of light to create a 3-D representation of sunlight's effect on a building from any location on earth, any time of day, any day of the year.
To represent an office envelope that minimizes solar heat gains and maintain views to outside, two scale models at 1:4 scale were built, one as a reference model (RM) illuminated through a sidelight window only and the other as a test model (TM )including also a light pipe and a light shelf.. The two scale models simulated south-facing deep open plan office spaces of 10 ft high, 20 ft wide and 30 ft long.
To predict more accurately the lighting and energy performance of our CFS, a larger experimental facility, was built at the Architecture Ranch Fabrication Facility at Texas A&M Riverside campus. It was built in an old shipping container which was adapted to represent a section of an office space with an unobstructed south view, at 75% of full-scale. The room dimensions were 30 ft long, 20 ft wide, 10 ft high.
New full-scale rotating room offers the highest accuracy of all the other models. The room is a low-cost facility with a manual rotation of 360°. The collected data in this room will serve to validate the lighting and energy performance of CFS in state-of-the-art simulation procedures.
