This dataset documents a three-year measurement series (January 2022 to December 2024) examining the thermal behavior of switchable liquid crystal glazing (eyrise S350) under real environmental conditions at a test facility in Stuttgart, Germany. Temperature measurements were conducted on double glazing units (DGU) and triple glazing units (TGU) installed in a south-facing facade test building with an 84% window-to-wall ratio. The study focused on heat distribution within the glazing assembly and the potential risk of thermal stress fractures caused by solar radiation absorption, particularly in clamped and shaded edge zones. A total of 80 Type K thermocouples were strategically positioned across eight glazing units to monitor temperatures in two distinct layers within the glass pane structure. The monitoring campaign captured temperature extremes ranging from -9.9°C to 79.9°C (TGU) and -7.3°C to 77.2°C (DGU), with critical temperature differences between center and edge areas reaching up to 47.9°C.
