Background Ventilation Assessment of Existing Buildings Training

03333 239045 |
Use of the process can avoid the unnecessary install of trickle vents and door undercuts where sufficient existing background ventilation is proven.

The IAA CS have developed a process for background Ventilation and Air Tightness Testing Training which was subject to a number of onsite assessments, technical input by BTS and underwent a rigorous assessment by TrustMark. Training and certification on this process is now available from The IAA, a process which can be applied to pulse and fan test users. 

What does the training course include?

This two-day course is knowledge based and practical with a live property assessment. On successful completion you will gain a certificate of competency in background ventilation assessment of existing buildings allowing you to register with iATS and use the agreed process. Those approved will be listed on The IAA website as being able to use the process to assess the need for background ventilation and will be able to provide evidence to support the lodgement of measures.

Course agenda:
  • Building Regulation
  • Competent Persons Scheme
  • PAS 2035 ventilation requirements
  • Measuring buildings
  • Health & safety
  • Building preparation and testing standards
  • Using the pulse software as one of the approved routes
  • Competency and practical test

Who can sign up to this training course?
This course is available to all individuals including IAA ‘end-to-end’ members who want to become ‘Approved Ventilation & Air Tightness Testers’.
There is a requirement for those individuals carrying out testing to be certified by either iATS soon to be renamed the Elmhurst Air tightness Scheme or the Air Tightness Testing and Measuring Association (ATTMA) and training is being offered to those installers who wish to pursue this route.
Please note the process does not replace the air tightness qualification under the certification scheme but instead builds on the use of this equipment. This provides a more specific assessment of background ventilation along with a more comprehensive approach to ventilation assessment based on actual performance of the property pre and post installation. This is an approach to address background ventilation requirements under pathway A and B of PAS 2035 and provides an alternative for pathway C whilst not replacing the airtightness testing requirements.

  • 2-day course - £425
  • All individuals will need to sign up to The IAA scheme at a cost of £250 per annum (this includes registration, annual surveillance and CPD). Scheme registration is free to IAA end-to-end members
  • Please note all who participate in the course will need to register with iATS or ATTMA, joining fees will apply to both schemes

Ventilation and Air Tightness Testing Service

This service provides a field-based solution for your background ventilation requirements. Conducting pre and post Energy Efficiency Measures (EEM) installation air leakage testing is to ensure ventilation requirements meet the PAS 2035 standards, whilst TrustMark compliant, without the need of additional background ventilation to be added which makes properties less airtight, resulting in additional energy consumption and costs.
