Evaluation of the Visual Comfort and Energy Performance of Shading Façades with Control Strategy in Response to Evaluation Indices

Effective shading control strategies are crucial for optimizing the performance of shading devices. However, the control strategies that optimize the performance of shading façade require further investigation. A response to evaluation index (REI) shading control strategy was proposed, and the performance advantages of three shading façades under this strategy were analysed. This study developed a model for assessing the visual comfort and energy performance of buildings by integrating Radiance, EnergyPlus, and Python. The accuracy of this model was calibrated and validated through a continuous ten-day experimental test that measured indoor temperature and illuminance distribution in a test room. The findings indicated that: (1) In terms of DGP, multi-sectional shading façade (MSF) and roller shading façade influenced by REI completely eliminated glare. This finding indicated that the selected indices were critical factor in glare prevention. (2) sUDI300–3000lx, 50% demonstrated superior performance across all shading façades when influenced by REI. The performance of sUDI300–3000lx, 50% under MSF was comparable to levels with no shading façade (NSF). (3) MSF exhibited the lowest lighting energy consumption, achieving a 15.04% reduction in total energy consumption relative to NSF.
