Predicted impact of linear roof apertures on the energy performance of office buildings

Technical Report ·
OSTI ID:6471889
The potential lighting electricity reductions and associated thermal impacts of replacing electric light with sunlight admitted through rooftop glazing on a single-story, prototypical office building were investigated. Experimental scale models were used to determine the fraction of the solar radiation entering the aperture which reaches the work plane as useful illumination. From this building energy analysis computer program was generated. Results of computer simulation indicate that a large fraction of the electricity consumed for lighting a single-story office building can be displaced using modest amounts of glazing in the roof. Smaller heating and cooling energy consumption reductions are possible from a daylighting system. The design implications of the results are discussed and future directions for the work are outlined.
