Our Practices / Building science
Optimize the building envelope through science
Building science focuses on the interactions between materials, construction systems, occupants, and their environment. It helps us understand air, heat, and moisture transfer, as well as their impacts on building performance, durability, comfort, and efficiency.
If walls can hear, the building envelope can speak. Envelope expertise reveals far more than visual defects: it reflects the effects of physical or weather-related phenomena on a building’s durability.
We believe that every visible issue deserves a thorough analysis.
A science dedicated to the built environment
Building science is the study of the interactions between materials, assemblies, systems, and environments. It helps us understand how air, heat, and moisture move—and how these exchanges affect building performance and long-term durability.
Our specialized team analyzes, simulates, and inspects all components of the building envelope—this crucial boundary between indoor and outdoor environments—to establish accurate diagnoses and recommend the right corrective measures.
