Specialized testing equipment establishes a controlled pressure difference between the building interior and exterior.
The amount of airflow required to maintain that pressure is measured, allowing total enclosure leakage to be quantified.
Commercial blower door testing can support hospitals, schools, colleges, public buildings, hotels, offices, multifamily properties, and other conditioned facilities.
For larger buildings, multiple testing fans may be required depending on building size and project requirements.
Whole Building Air Leakage Testing
A building enclosure can contain numerous potential leakage pathways.
Windows, doors, wall transitions, roof interfaces, mechanical openings, penetrations, and joints can each contribute to total building leakage.
Whole building air leakage testing in Lander evaluates these conditions collectively.
QED LAB uses controlled pressure testing and airflow measurement to provide quantitative information about overall enclosure airtightness.
Testing can support commissioning programs, energy-related requirements, new construction verification, and other project-specific performance criteria.
ASTM E783 Window Air Leakage Testing
QED LAB provides ASTM E783 testing in Lander for field measurement of air leakage through installed exterior windows and doors.
A specified pressure difference is established across the assembly while airflow is measured.
The resulting data provides quantitative information about the leakage performance of the installed component.
Window air leakage testing in Lander can be particularly useful for schools, healthcare buildings, colleges, hotels, offices, government facilities, and multifamily developments.
ASTM E783 may also be coordinated with ASTM E1105 when both air and water performance require field verification.
