Effect of Interior Space and Window Geometry on Daylighting Performance for Terrace Classrooms of Universities in Severe Cold Regions: A Case Study of Shenyang, China

Good daylighting performance positively affects students’ physical and mental health, learning efficiency, the building’s energy-saving capability. Due to terrace classroom having ample space, large capacity, ability avoid obstructing sight, meet various use needs, it is most important place in university buildings. However, research on of classrooms limited, leading a lack quantitative guidance early design stages. This study aims explore effects interior space window geometry universities severe cold regions performance. took Shenyang as an example; spatial daylight autonomy (sDA300,50%) useful illuminance (UDI100–2000) were selected evaluation indices. Based Grasshopper parametric platform, simulation was carried out using Ladybug Honeybee plugins. Correlation regression analyses revealed relationship between parameters The results showed following: window-to-floor ratio (WFR), height (Htc), (Hw), window-to-wall (WWR), width (Wtc), (Ww) have positive improving sufficiency facing each orientation, degree effect decreases order. To ensure overall performance, Wtc can be maximized. walls windows for south-facing west-facing should 0.9 m. WWR WFR 0.3–0.5 0.11–0.14, respectively. north-facing 0.6–0.7 0.14–0.20, Prediction models are established sDA300,50% UDI100–2000 orientation.
