Approved Document G

Stay compliant with sanitation, hot water safety, and water efficiency regulations outlined in Approved Document G. Guidelines for building design, construction, and effective water-related systems to ensure proper sanitation, safe hot water supply, and efficient water usage.

Air Changes per Hour at 50 Pascals (ACH50)

Air Changes per Hour at 50 Pascals (ACH50) quantifies building air tightness under standardized test conditions. Discover how it helps evaluate energy efficiency, identify air leakage, and guide air sealing efforts for improved building performance.

Zonal Pressure Testing

Zonal Pressure Testing evaluates airtightness and pressure relationships between different zones in a building. Explore how this diagnostic procedure identifies air leakage, verifies compartmentalisation measures, and guides improvements in energy efficiency and ventilation for optimal building performance.

What is an air test also known as?

An air test, also known as an air permeability test or an air leakage test, is a crucial assessment conducted in the construction industry. It evaluates the airtightness of a building by measuring the rate at which air infiltrates or escapes through its envelope. This test provides valuable insights into the building’s overall air leakage performance, helping identify areas that may require improvements. By conducting an air test, construction professionals can enhance energy efficiency, improve indoor comfort, and ensure regulatory compliance.
