Abstract

An innovative center-mounted louver ventilation window suitable for seasonal ventilation strategies was proposed, combining the regional climate of Qingdao. The sustainable development concept is embodied, which can not only reduce building energy consumption but also consider the quality of daylighting. This research constructed a comprehensive evaluation framework, taking an office building in Qingdao as an example. The framework utilized the parametric design platform Grasshopper and its environmental design plug-in Ladybugtools. It considered the daylighting performance and energy consumption of the building. This study included six different ventilation strategies, with energy use intensity and useful daylight illuminance as evaluation indicators. The results indicated that the seasonal ventilation strategies and parameters of blinds were optimized to significantly improve the energy efficiency of the building without compromising daylighting quality. The optimized solution reduces energy consumption from 83.81 kWh/m 2 to 55.0 kWh/m 2 , achieving a 34.4% reduction while maintaining a high UDI. This energy-saving effect reveals the influence of different ventilation strategies on energy and daylighting. And it provides an important reference for sustainable design in similar climate contexts.
