Drone over buildings.The RCI Foundation Canada has approved a grant proposal from the University of Victoria to review infrared (IR) thermal assessment of roof assemblies via stationary and dynamic measurement and to establish a best practices guideline for thermographers, researchers, and IIBEC consultants.

Professor Phalguni Mukhopadhyaya, PhD, PEng, FEC, FCSCE, FCAE, of the University of Victoria in the Department of Civil Engineering, will manage this project in collaboration with Dr. Milad Mahmoodzadeh (Morrison Hershfield, now Stantec) and Voytek Gretka (RDH Building Science Inc).

According to Mukhopadhyaya, “This research intends to demonstrate how robust measurements can be obtained for the utilization of aerial thermography for the thermal assessment of roofs using both qualitative (detecting and locating thermal anomalies such as thermal bridges, air leakage, and moisture) and quantitative (U-value of Insulation) approaches.”

According to Ted Sheridan, Treasurer of the RCI Foundation Canada, “The results of this grant will be invaluable in moving our profession forward as many of our members are now using drones to assess the building enclosure daily. We have already found great value in IR thermography, and this will expand our understanding of aerial IR assessment capabilities in the process.”

The objectives of this project are to:

  • Examine the viability of dynamic measurements (UAV mounted IR camera) relative to stationary measurements (handheld IR camera) for qualitative and quantitative thermal assessment of roof assemblies
  • Establish relationship between stationary and dynamic IR measurements
  • Develop best practice guidelines to maximize measurement accuracy in aerial thermography of roof assemblies

These practices will be valuable for thermographers and researchers to develop a robust protocol that accounts for the impacts of the camera’s performance.

Research is expected to be completed by May 2026. “An important goal here is a best practices guideline for the use of aerial thermography for roof assessments,” Sheridan said.
