Assessing solar performance in advanced facades: Comparative analysis of control strategies using a dynamic key performance indicator

Recent advancements in transparent façades that adapt to environmental conditions have improved energy efficiency and occupant comfort, addressing greenhouse gas emissions from buildings. However, traditional metrics like SHGC may not accurately measure dynamic façade performance in real-world conditions due to their steady-state approach. In this work, a novel Key Performance Indicator KPI, i.e., the Daily Integrated SHGC, is utilized with EnergyPlus dynamic simulations to evaluate the solar performance of windows with various shading system configurations under different control logics. Findings indicate that the new KPI offers insights into the thermal impact of different control logics, allowing to account in the assessment also for dynamic environmental factors.
