Commercial Air Tightness Testing FAQs

  • Commercial air tightness testing measures the level of uncontrolled air leakage through a building envelope and verifies overall air permeability performance.

  • Air tightness testing is commonly required for new commercial developments and may form part of Building Regulations compliance requirements.

  • Testing may be undertaken on offices, retail buildings, industrial facilities, hospitality premises, educational buildings, healthcare facilities, and other non-residential properties.

  • A calibrated fan system is used to pressurise and depressurise the building while measuring air leakage rates through the building envelope.

  • Testing can identify leakage pathways and support improvement measures intended to enhance building energy performance.

  • Leakage areas can be investigated and remedial measures identified before retesting where necessary.

  • Air tightness data may contribute to wider building energy performance evaluations and compliance assessments.

  • Testing duration depends on building size, complexity, and project requirements.
