ATTMA Air Tightness Testing Level 2

by ATTMA,

This 3 day course provides both the knowledge and understanding required to air tightness test simple and non-simple buildings except those defined as defined as:

  • Large buildings with an envelope area over 80,000 m2
  • High rise buildings with more than 15 storey
  • Phased or zonal handover buildings

Prior Knowledge

To pass the course it is recommended that delegates:

  • Have a least 1 year of experience as a level 1 tester
  • Are familiar with the ATTMA technical standard TSL2

Course Content

The course includes a combination of both presentation and exercises on the first 2 days and the 3rd day is dedicated to examinations.  The course content covers the minimum knowledge and understanding identified in the National Occupational Standards for a level 2 tester and this includes:

Presentations

The presentations cover the following key topic areas:

  • The ATTMA scheme
  • A background to air leakage
  • Equipment used for air tightness testing
  • How to setup the equipment for a multi-fan air tightness test
  • The air tightness testing test standards
  • The test procedure and multi-fan testing
  • Building regulations
  • Contracting
  • Quality assurance

Exercises

The course has the following exercises:

  • 3 tests undertaken on a non-domestic building
    • Multi-fan full building test
    • Compartmentalised building test
    • Two Zone tests
  • A theory exercise
  • 2 contracting exercises

Examinations

On the 3rd day the examinations are split into 2 key areas which are:

  • Practical examination with the testing of a building
  • Multiple choice theory examination

Equipment

The following items must be brought to the course:

  • Laptop
  • Scientific calculator or a smart phone

Note: All level 2 testing companies are required to have at least one person that has the EA level.  This is a qualification that demonstrates a knowledge and understanding of advanced envelope area calculations and companies without a person with this qualification will be unable to operate at level 2.  The EA qualification can be obtained through either completing and passing the Advanced 3D Modelling course or by submitting evidence of prior envelope area calculations on level 2 and 3 buildings for review via the approved prior experience and learning (APEL) route.
