Data for: Thermal behaviour of switchable liquid crystal glazing under real environmental conditions

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.<br>
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.
