Deep Retrofit Air Tightness Verification
-
An air tightness test measures the amount of uncontrolled air leakage through a building envelope and quantifies overall air permeability performance.
-
Air tightness testing is commonly required to demonstrate compliance with Technical Guidance Document Part L and associated building energy performance requirements.
-
A calibrated fan system is installed in an external doorway to pressurise and depressurise the building while measuring air leakage rates.
-
Most residential air tightness tests can be completed within a few hours, depending on dwelling size, complexity, and site conditions.
Residential Air Tightness Testing FAQs
-
Windows, doors, ventilation openings, and service penetrations should be prepared in accordance with testing requirements before the assessment is undertaken.
-
Air leakage pathways can be identified and remedial measures recommended before retesting where necessary.
-
Air tightness results may be incorporated into BER calculations where appropriate and can influence overall building energy performance outcomes.
-
Air tightness testing can establish a baseline performance level, identify areas of uncontrolled leakage, and help verify the effectiveness of retrofit measures.
