Eric Fewster

Eric Fewster is a Certified Passivhaus Consultant, PHI Retrofit Expert and Passivhaus trainer, specialising in retrofit projects.

Specialising in energy efficiency master planning for refurbishment projects, Eric offers detailed baseline energy analysis using Passive House methodology and thermal bridge modelling, followed by an action plan of improvements that enables individual homeowners to plan towards specific space heating demand targets. The plan is not only about the energy analysis that we do ourselves, but also involves coordinating with other specialists as needed in order to progress the planning (e.g. for MVHR design, hot water / heating / renewables design, structural analysis, window & door schedules, and moisture modelling).

Training in low energy building techniques for retrofit and new build, Eric is a trainer with Coaction, which is a group of trainers running the Passivhaus Tradesperson course that has been running since 2018. He helped to develop the material for this training, and continue to help run the training online. He also does one-on-one retrofit training and mentoring, as well as on-site training on request.
