Experimental data on heat transfer and surface temperature profiles of a triple-glazed unit with active heating foil.

Sheet 1: Summary_Data

Contains averaged steady-state values used for the primary analysis (corresponding to Fig. 3 and Fig. 4 in the associated publication). It includes vertical profiles of heat flux density (q) and surface temperatures for both reference (passive) and active (heated to 60) states of the triple-glazed unit.

Key variables: H (height), qext (external heat flux), qint (internal heat flux), Text (external surface temperature), Tint (internal surface temperature).

Sheet 2: Raw_Sensor_Readings

Provides high-resolution temporal data recorded at 10-second intervals during the final minute of the steady-state period. This sheet serves as technical proof of measurement stability and includes raw sensor output in microvolts (μV) from the Hukseflux LI19 logger.

Key variables: Timestamp (s), HeatFlux (W/m²), Surface temperatures (°C), Sensor Voltage (µV).

Sheet 3: Climatic_Chamber_Logs

Presents the environmental boundary conditions maintained throughout the experiment in the dual-zone climatic chamber. It documents the stability of the simulated winter environment.

Key variables: Outdoor/Indoor temperature (°C), Relative humidity (RH (%)), and Air velocity outdoor (m/s).

Sheet 4: Metadata_Full

Contains comprehensive project identification, including the National Science Centre (NCN) grant number (DEC-2025/09/X/ST8/00339), detailed list of equipment used (Hukseflux, Lutron, H-Tronic), and institutional affiliation.
