In-Situ Thermal Monitoring Dataset: Heat Flux, U-Values, and Infrared Imaging for Building Façade Evaluation

This dataset presents field-measured thermal performance data collected from a building in Ireland, encompassing in-situ U-value assessments of wall and window façade elements alongside thermographic imagery. Time-series recordings of heat flux and surface temperatures are included, enabling the derivation of thermal transmittance values across multiple envelope components. The dataset is intended to support researchers and practitioners involved in building energy auditing, façade condition monitoring, and the planning and evaluation of retrofit interventions aimed at improving the thermal efficiency of existing building stock.
