Blower Door Test

A diagnostic test that measures the airtightness of a building. A calibrated fan is used to depressurise or pressurise the building, and the resulting airflow is measured to determine the air leakage rate.

Building Emission Rate (BER)

Building Emission Rate (BER) is a crucial metric for evaluating a building’s carbon emissions. Learn how BER is calculated, its significance in sustainable construction, and its role in reducing the environmental impact of buildings.

Positive Pressure Test

The Positive Pressure Test, also referred to as a pressurisation test, evaluates a building’s airtightness by increasing the interior pressure. Discover how this test identifies air leakage, measures energy loss, and guides improvements in energy efficiency and indoor comfort.

Airtightness Target

An Airtightness Target sets the desired level of air leakage for a building, ensuring energy efficiency and indoor comfort. Explore how it is determined, the role of testing, and the benefits of meeting the Airtightness Target for optimal building performance.
