Abstract
Under the goal of analyzing the compulsory supply share of new renewable energy according to the application of a daylighting system to indoor gymnasiums, this study conducted analysis of energy consumption and operation schedule at three indoor gymnasiums in the nation through a survey. The investigator did an Energy Plus simulation on Building A based on the analysis results and analyzed the supply share of new renewable energy in the saving effects of lighting energy according to the application of a daylighting system. As a result, When 92 prism daylighting system were installed in the upper ceiling of a stadium, they were able to meet the criteria for the minimum illumination for official games(Min : 600㏓) and optimum illumination for general games and recreations, thus saving lighting energy during the daytime(09:00~17:00). The resulting saving effects of lighting energy amounted to 44.4% for official games, 57.6% for general games, and 66.7% for recreations. In addition, the daylighting systems had a compulsory supply share of new renewable energy at 2.04% for official games, 2.75% for general games, and 2.62% for recreations, recording an average compulsory supply share of 2.5%.
