Passivhaus Retrofit Masterclass lecture series

Passivhaus Retrofit
2022 Large and Complex Passivhaus Masterclass

As part of our retrofit campaign, April 2022 marked the conclusion of our popular Passivhaus Retrofit Masterclass lecture series. The series addressed multiple constructions from solid wall to cavity construction, covering both residential & non-domestic challenges.

The popular series is now available as recorded modules that can be completed at your leisure. Each Masterclass lecture shares first-hand experiences from expert practitioners to enrich your practical and technical knowledge about how Passivhaus can apply to your future retrofit projects.

The Masterclass lecture series is aimed at anyone interested in designing and delivering Passivhaus retrofit projects, including: architects, engineers, home-owners consultants, contractors, local authorities and self-builders.

Learning outcomes

By the end of this module you will be able to understand: 

  • Practicality, opportunity and budget of various domestic retrofit measures 
  • Ingredients of successful retrofit – energy conservation/ energy efficiency/ renewable energy 
  • Advantages of insulating on the outside of cavity walls with external wall insulation – lower risk of condensation/ lower risk of thermal bridges 
  • Building tight: Application of insulation, what type, thermal bridges, location, and need to ventilate right. The critical importance of having a robust and effective ventilation strategy. 
  • High risk cavity walls and Moisture sources in cavity wall: rising damp, rain, leaks, indoor activities 
  • Why cavity walls are challenging to treat – form factor/ less airtight/ less desire to add insulation 
  • Optimisation of heating options following fabric improvement and consideration of renewables
