This open-access dataset contains raw and processed high-temporal-resolution experimental time-series logs supporting the research paper presented at the "CONECT conference: "Autonomous PV-Powered Smart Windows: Active Glass Heating in NZEB Applications"

Available at: https://ect-journals.rtu.lv/conect/article/view/CONECT.2026.001

The dataset package consists of the following data files:

1) climatic_chamber_high_res_timeseries.csv
   - Resolution: Minute-by-minute logs (720 records)
   - Scope: Laboratory test cycles inside a dual-zone climatic chamber 
     replicating baseline scenarios (T_ext = 0 °C and T_ext = -25 °C) 
     across both passive and active states (25 W thermal barrier active load).

2) insitu_field_high_res_timeseries.csv
   - Resolution: Hourly intervals (2160 records)
   - Scope: Environmental and electrical time-series parameters capturing 
     real-world operational profiles across January, February, and March 2026.
