Commercial Air-Leakage Testing

A whole-building air-leakage test uses test fans to hold a building's enclosure at a controlled pressure difference and measures the airflow needed to maintain it. That airflow is the enclosure's leakage, and it is compared with the acceptance criterion in the governing code, specification or program for the defined test boundary. Because the boundary, the method and the criterion determine what the number means, we settle all three before the fans are scheduled.

Commercial Envelope Testing Co., a wholly owned Green Summit company, delivers commercial air-leakage testing. Your engagement identifies the contracting entity, the test team, the equipment and the reporting responsibilities, so there is no ambiguity about who is on site and who signs the report.

We review the drawings, the enclosure boundary, the required method, the acceptance criteria, the fan requirements, access and building preparation. Every one of those decisions is settled before the scheduled mobilization, because a test day spent resolving them is a test day lost.

No. The required boundary depends on the code, the specification and the project configuration. We establish exactly what is being measured and distinguish whole-building, unit and compartment testing before we plan the setup, so the result matches the requirement rather than a convenient assumption.

The report documents the measured results and the conditions under which they were obtained. We then define diagnostic follow-up, repairs and retesting as their own work. A test is never a guarantee that the building will meet the acceptance criterion; it is the measurement that tells you where the building stands.

Yes. We provide a defined testing work package while the commissioning firm retains its client role. We coordinate access, schedule, evidence and reporting interfaces with the commissioning team in advance, so the test fits their program instead of competing with it.
