Experimental Rotating Room for Daylighting Studies Institutional Repository Document uri icon


  • This paper presents the design, development and construction process of an experimental rotating room to study the performance of complex fenestration systems (CFS). The room, of 600 ft2 represents a workspace of 20 ft wide, 30 ft deep and 11 ft high with two windows 9' wide by 5' high. The room was built with Structural Insulated Panels (SIP) over a metal structure on four casters that can rotate 360 degrees around a central axis. The room has high performance windows, automated external louvers, energy efficient lighting, lighting controls, DALI controller, and a horizontal passive solar light pipe system. Data collected in this facility will serve to evaluate the energy consumption and lighting performance of integrated building technologies. Visual comfort will be assessed at different viewpoints in the testing room to detect glare, contrast, and compare them with occupant’s responses.
