Air Barrier 1A typical building uses 30% of its energy to compensate for losses due to air leakage across the building envelope. The need to control the air entering and leaving your building is not only an air quality issue; it is also a cost issue. By making a building more air tight, and thereby increasing the building’s performance, you are able to reduce the loss of the conditioned air through the building enclosure. This allows you to reduce the load on the HVAC&R systems and design a more efficiently sized system.

CTI Consultants, Inc. provides air barrier consulting and performance testing services that include:
  • Pre-design consultation with the project team on air barrier assemblies and systems, detailing, and material specifications.
  • Air Barrier 2Technical plan and specification reviews to ensure that air barrier components, joints, interfaces, and penetrations are appropriately detailed.
  • Material submittal review and mockup testing.
  • Quality Assurance field observations during construction to identify typical compliant and non-compliant construction methods.
  • Air barrier testing with infrared thermography diagnostic techniques to identify air leakage pathways.
The Air Barrier Association of America (ABAA) defines an air barrier as an assembly to “control the unintended movement of air into and out of a building envelope.” By reducing the uncontrolled passage of air through the building envelope to almost negligible amounts, the air barrier lowers energy consumption by reducing the associated heating and cooling loads as well as allowing designers to reduce the size of the HVAC&R system requirements.

Air Barrier 2Since 2007, CTI has provided industry leadership in the advancement of air barrier performance. CTI is a technical consultant to ABAA, ASTM, ASHRAE, National Institute of Building Sciences (NIBS), and the Army Corps of Engineers (USACE) in their development of the air tightness testing protocol, ensuring our clients that our large building testing methodology and equipment will conform to the requirements of their project including:
