Abstract | IRC has released the final version of its SkyVision software for predicting skylight performance afterextensive validation testing on the beta version released last year. Skylight designers, skylightmanufacturers, building designers, fenestration rating councils, architects and educators can use the toolto predict the daylighting performance and energy saving potential of conventional and tubular skylights.This report outlines the test methodology to measure the skylight performance, and presents thecomparison study between the software's predictions and the actual measurements. This report alsoincludes a comparison with the results of the California PIER (Public Interest Energy Research) programfor the effective transmittance of skylight and well combinations. The results of the PIER programcovered additional skylight settings, and provided valuable benchmarks not only for the effectivetransmittance, but also for the thermal transmittance (U-value) and the solar heat gain coefficient ofprojecting skylights. |
