We are delighted to announce that Stephen Holland, RRC, PE, and Terrance Dumoulin, EIT, members of the firm’s Enclosure Group, have published a feature article in the November 2025 issue of IIBEC Interface, the official journal of the International Institute of Building Enclosure Consultants. Their article, “Can You Feel the Heat? Cross-Typology Building Facade Performance Evaluations Using Infrared Analysis,” highlights the critical role of infrared (IR) thermography in improving the performance of existing building enclosures.
The article presents findings from an in-depth study of 17 dormitory buildings across the campus of a university in the Northeast, representing a wide range of construction types and eras—from late-19th-century mass masonry to mid-20th-century precast concrete and wood-framed structures. Using ASTM E1186 as their testing framework, the team observed firsthand how thermal bridging and air leakage vary across different building types, and why each scenario requires its own unique repair strategy.
Their research illustrates how IR thermography can expose hidden performance issues such as slab-edge thermal bridges, missing insulation, deteriorated window assemblies, and complex air barrier discontinuities at roof and wall transitions. Rather than just pointing out what’s wrong, the study highlights the importance of interpreting the data correctly and pairing it with real-world enclosure expertise to select retrofit solutions that both reduce energy use and improve building occupant thermal comfort.
Stephen brings years of hands-on experience investigating and retrofitting existing and historic buildings, grounding the study in real-world enclosure practice. Terrance, whose work centers on enclosure simulation and deep energy retrofit design, added a strong analytical perspective that helped shape and strengthen the findings.
As the industry rapidly moves toward decarbonization, electrification, and net-zero goals, this work serves as a poignant reminder of the value of early, thoughtful enclosure evaluations, particularly for campuses and organizations managing aging buildings. This study adds real value to how IR analysis is understood and applied, and it reflects the high standards we strive for at LeMessurier. We congratulate Stephen and Terrance on their hard work and for their contributions to the enclosure community through meaningful research.
