Key Services

Large Building Airtightness Testing  

  • Building airtightness is a key performance indicator in determining operational energy efficiency, building durability, and occupant comfort. We’re industry leading experts in successfully working with teams to incorporate airtightness testing as a method of building envelope airtightness verification, quality control, and as a method of continuous improvement as we strive towards high performance structures. Contact us to discuss the feasibility of incorporating airtightness testing into your construction process.

Guarded Airtightness Testing 

  • We understand that performing a whole-building airtightness test may not be feasible or desired. A guarded airtightness testing approach is a method used to isolate and quantify air leakage through just the exterior envelope in a space that also have interior partition walls. .

Adhesion Testing

  • An air barrier system is as strong as its weakest link. Rated air barrier materials are effective at controlling air flow through assemblies and we almost exclusively find air leakage occurring where two air barrier system materials are connected. We rely on this connection to be airtight and we rely on this connection being durable for the service-life of the structure. 

  • We use calibrated equipment to test the adhesion of air barrier system materials to help verify its effectiveness and durability. 

Airtightness Consulting  

  • Achieving airtightness is a performance metric that can’t be purchased but rather needs to be incorporated as a process. This is a process that starts in the initial design phase and will require efforts through to project completion. Of the many factors involved in assemblies an effective air barrier system some of the key factors to consider are what the air barrier system materials are, who’s installing them, when they’re being installed, and how quality control will be monitors. 

  • We work with teams to implement airtightness strategies that help ensure high performance air barrier systems are achieved.

Window Testing

  • Windows and glazing assemblies are an essential part of a building envelope and are often a weak link (or failure point) for air and water leakage. We perform field testing to ensure that the installed units meet the criteria of the laboratory rated performance specifications.

Thermal Bridging Analysis

  • Managing thermal bridging is an important aspect of maintaining effective R-values and reducing the risk of condensation occurring within or on the surface of construction assemblies. We perform thermal bridging analysis on construction and glazing assemblies.

Effective R-Value Calculations for Building Assemblies

  • Construction assemblies on a whole are often derated from the clear wall insulation value due to thermal bridges that are part of the structure. For most accurate energy modeling results we calculate effective R-values for construction assemblies.

Hygrothermal Condensation Risk Analysis

  • A hygrothermal analysis studies the thermodynamic profile of a construction assembly as a whole. The performance is impacted by factors such as the thermal resistance, permeability, and thickness of each component in the assembly. A hygrothermal analysis will assess the risk of dewpoints and condensation in wall assemblies and provide insight into issues such as mold growth and decay.


Sustainability Consulting

  • As we move towards net-zero buildings, we need to incorporate renewable energy systems to make this feasible. Achieving net-zero is a balance of building envelope, mechanical systems, and renewable energy.

  • We provide consulting on which on-site renewable energy systems are available and applicable to your project.
