Building Enclosure Testing


"WJE professionals bring value to each building enclosure testing project by combining our technical insight with hands-on experience. We collaborate with the project team to assist in achieving building enclosures that work."

— Rita Ray, Associate Principal and Unit Manager

With dual commitments to performance and aesthetics, a building’s enclosure system must meet challenging standards, beginning at the time of design and construction and continuing through its service life. Thorough testing of components prior to and during construction achieves a completed structure that fulfills the client’s requirements and expectations. Post-occupancy building enclosure testing can help address known issues or can be integrated into a regular maintenance program aimed at maximizing service life and reducing costs.

A comprehensive building enclosure testing plan is the most reliable method for identifying areas of concern related to air leakage, condensation, and rain water entry—issues that can impact the long-term durability, energy efficiency, and indoor air quality of a building. We employ experienced professionals and state-of-the-art modeling and analysis techniques to anticipate performance, identify issues, and refine new construction design details and/or repair designs for existing enclosures. Laboratory and field mock-ups help determine baseline requirements and methods for installation of systems and components. Functional performance testing, such as water testing or whole-building air testing, helps us validate a repaired or newly installed enclosure’s ability to meet performance criteria and expectations.

Our professionals help clients build responsible, durable, and maintainable structures. This is achieved through careful evaluation and testing of the various components to verify continuity of systems and conformance with the owner’s expectation and design intent.
