This paper introduces novel Key Performance Indicators (KPIs) for assessing the solar performance of glazing units under dynamic, realistic conditions. Such new proposed KPIs — Daily Integrated SHGC and Maximum Solar Gain Ratio MSGR — provide a more accurate reflection of a building's energy performance by considering daily variations in solar exposure and the way the radiation is transferred through a complex transparent component. This research aims to validate the new KPIs in a simulated environment before applying them to actual building components, offering a comprehensive evaluation of their variability with changing environmental and configuration variables.
