| Abstract |
Currently, large amounts of energy have been consumed in every parts of industry. Especially, energy consumption in the building sector account for 40% of energy consumption worldwide. Therefore, reduction of energy consumption and efficiency improvement in buildings are very important issue in worldwide. For building energy savings, we need to evaluate energy performance in design stage and operation stage with optimized alternatives. However, building energy efficiency improvement technologies in building operation stage is still not matured. For better understanding of building energy performance with operation schemes, we studied an approach for building energy performance with a change of building operation according to daylighting. In this study, first, we investigated building information to implement energy analysis. Then, we generated an energy analysis model and conducted building energy performance evaluation with various building operation alternatives. Based on this approach, we conducted a case study to research building energy saving potential according to daylighting in operation stage. |
