What is an air tightness test?
Air tightness is a vital component of sustainable design. Draughty or leaky properties are expensive to heat and may not be comfortable to live in. With the increase of efficiency in insulation materials, air infiltration is becoming more and more important. Nowadays, building design is aiming for high energy efficiency and good indoor air quality. To ensure that energy efficiency is high and air quality is good – an air tightness test is required.
A test depressurises the building using a fan and measures the air flow at a range of pressure differentials. The test result expresses the airflow rate across the insulation envelope or internal surface area, in m³/(hr.m²)@50Pa. Air temperature and barometric pressure are taken into account. Smoke tests can identify the source of any leakage and we always offer advice if a building fails a test for being too air tight or too permeable.
The target airflow rate for a new building is described in the Standard Assessment Procedure (SAP) calculations, for domestic dwellings and the Simplified Building Energy Model (SBEM) for commercial buildings.
Air Permeability Regulations
The Scottish Government outlined their move towards zero carbon development in the Climate Change (Scotland) Act 2009. Section 6 of the 2010 Scottish Building Standards requires a reduction of 30% in CO2 emissions from domestic buildings from the 2007 Standards. To help achieve this, mandatory air tightness testing was introduced for new builds in 2011.
Air Tightness Testing can also be carried out on any building seeking to improve energy efficiency and reduce heat loss.
