Passivhaus Contractor Training now available as part of AECB CarbonLite

A new 2-day course tailored to all contractors and builders involved or interested in low-energy building at any level has been added to the AECB CarbonLite training programme.

The course centres on core Passivhaus (fabric-first) building techniques that are suitable for every level of new build and renovation project, and includes both theoretical & practical sessions. In addition, there are optional revision & exam sessions available for those wanting to become qualified as a Certified Passivhaus Tradesperson, which is one of the highest international quality marks available to demonstrate competence in the field of low-energy construction.

The first date scheduled for this new training opportunity is 29-30 October in Manchester (venue to be confirmed), followed by a further optional half day of revision on 9 November, and the half day Passivhaus Certified Tradesperson exam on 17 November. Find more details and book online at, or download the flyer here.

The course is managed on behalf of CarbonLite trainers and the AECB by WARM Low Energy Building Practice.

What will it involve? Theory…

There are very few trainings available in the UK that cover all the essential aspects of low-energy construction, including what it means practically when implemented on site. This training aims to fill this gap, providing knowledge & expertise in these key aspects of fabric-first construction for both new build and retrofit:

  • Insulation
  • High performance glazing
  • Airtightness & windtightness
  • Thermal bridging
  • Building services, with a focus on ventilation with heat recovery

Theoretical issues are linked to real life field experiences of the facilitators throughout the course.

…and practice

This training has several practical aspects, which include the following:

  • Insulation – installing flexible & rigid insulation (wood fibre) using thermally-broken fixings
  • Airtightness – installing membranes to different substrates with a variety of tapes & adhesives
  • Blower door test – understanding what to look for when a house is tested
  • Various practical calculations & exercises as part of theoretical sessions on airtightness and thermal bridging

Certified Passivhaus Tradesperson


For those wanting to gain the prestigious qualification of Certified Passivhaus Tradesperson, there’s also the option to attend a half-day revision session, followed later by a 90 minute exam. Those that qualify are then allowed to use the Passivhaus Tradesperson logo and will be registered on the global database for a period of 5 years. After this time, renewal is done through submitting evidence of experience with low-energy construction, or through additional training.
