Further improvements to backstop performance levels have come into effect with the publication of the .Also known as “air barrier”, “air leakage”, “blower door” and “pressure” testing, air tightness testing is required by the US Army Corps of Engineers, NAVFAC and a growing number of municipalities, states and federal government agencies for all new conditioned buildings as well as for renovation projects totaling 25% or more of a building’s replacement value.Building airtightness (also called envelope airtightness) can be defined as the resistance to inward or outward air leakage through unintentional leakage points or areas in the building envelope.This air leakage is driven by differential pressures across the building envelope due to the combined effects of stack, external wind and mechanical ventilation systems.cooling costs for building owners and occupants, and increasing risk related to comfort and durability. Air tightness testing can result in more attention to envelopeassembly air barrier sealing and significantly reduced building leakage. Currently, the commercial energy code allows air tightness testing for buildings
The air permeability test, also known as the air tightness test or air leakage test, is a mandatory requirement of Part L of the Building Regulations 2021. This applies to all new build commercial buildings over 500 square metres and extensions with a floor area greater than 25% of the current building.Planning a Test: 4: Apply an appropriate airtightness test approach.

This is to ensure that they comply with CO2 Carbon Emissions policy and to minimise unnecessary heat loss through air leakage to reduce the cost of running.
Common Standards for Air Barrier Testing. ASTM E1827 – Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door An alternative to ASTM E779 that allows for testing a wider range of buildings; ASTM E1186 – Standard Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier SystemsAir tightness testing is an air permeability test, which is carried out by a professional testing company to identify the volume of air that can escape from a building. ATTMA Part TSL1 and ATTMA Part TSL2 in Non-dwellings provide a clear guidance on how to make buildings more energy efficient, cost effective and comfortable. Air tightness testing, also known as a blower door test, is a diagnostic procedure used to quantify the air permeability of a building’s envelope. This test involves creating a pressure differential between the inside and outside of the building to force air through any unsealed cracks or openings, thereby measuring the air leakage rate. In April 2002, the UK government introduced air tightness testing alongside the Building Regulations law to enforce standards of dwelling air tightness. The legislation was created in order to lower running costs, verify the standards of materials, prevent uncomfortable drafts and avoid condensation problems.
