Our Level 2 training is designed to progress Air Tightness Testers from Level 1 to carry out multi-fan testing for larger commercial buildings. Level 2 training includes:
Level 2 training includes:
Module 1: Basic Envelope Area Calculations: A refresher module in 3D modelling of simple envelope areas and volumes.
Module 2: Advanced Envelope Area Calculations: Covering advanced envelope area calculation techniques needed for Level 2 testing,
including circles, ellipses and curves, multiple angled pitch roof interfaces, and tapering on plan with a pitched roof.
Module 3: Multi-Fan Testing: Covering the testing of larger and more complicated buildings with multiple fans, including testing larger buildings with multiple fans, permanently compartmentalised buildings and large extensions to commercial buildings.
Module 4: Multi-Fan Practical: The application of the information covered in module 3.
Examinations: A practical exam, involving the testing of a large commercial building and a multi-choice theory exam covering modules 3-4.
Level 2 training also allows trainees to register as an Envelope Calculation Technician. The Envelope Calculations module is for individuals who are authorised to carry out envelope area and volume calculations but are not authorised to test.
