Building Air Tightness Test

What is building air tightness test?
  • Air tightness testing is a process in which the building envelope is tested to quantify the air tightness.

  • The test measures air leakage rates through a building envelope under controlled pressurization and depressurization.

Function of building air tightness test
  • Can see data with figures & numbers for the air flow going through building envelope.

  • Can find where leaks happen with data of pressure test and photos of infrared camera.

  • 2015 IECC (International Energy Code Council)

  • U.S. Army Corps of Engineers Air Leakage Test Protocol for Building Envelopes

  • ASTM E779 – Standard Test Method for Determining Air Leakage Rate by Fan Pressurization

  • ASTM E1827 – Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door

  • ISO 9972:2006 – Thermal performance of buildings — Determination of air permeability of buildings — Fan pressurization method
