Air Tightness Testing

Air Tightness Testing

Air tightness testing (also known as blower door testing) is essential for measuring how much air escapes from a building.
It’s a legal requirement for new dwellings under Ireland’s Building Regulations Part L and plays a key role in achieving NZEB (Nearly Zero Energy Building) standards.
At Kenergy Consultants, we provide certified air tightness tests for residential and commercial properties across Ireland.

Why Air Tightness Matters

  • Improves energy efficiency and BER ratings
  • Reduces heating costs and carbon emissions
  • Required for Building Control and SEAI grants
  • Supports comfort and indoor air quality

Who Needs It?

  • New builds and extensions
  • Retrofit projects applying for SEAI grants
  • Developers and self-builders
  • Commercial and office developments

How It Works

  1. Preparation – We’ll advise you on how to get the building ready for testing
  2. On-Site Test – Using a calibrated blower door fan, we pressurise the building to detect air leakage
  3. Leak Detection – If required, we help locate and identify problem areas
  4. Certificate & Report – You receive a certified test result for submission to Building Control
