Multi objective optimization of window to wall ratio of University Gymnasium in severe cold area by coupling natural lighting and energy consumption

Objective To explore the relationship between window opening ratio and natural lighting energy consumption of University Gymnasiums in severe cold area, put forward optimization strategies. Methods Digital simulation technology was used to simulate Gymnasium ratio, scheme with low obtained. Conclusion The side should be small medium-sized university gymnasiums. Within range experimental data, North-South is main mode, East-West auxiliary.
