Certified Passivhaus Consultant and AECB Carbonlite Retrofit graduate.
Hands-on experience of retrofit and new-build, combined with technical and theoretical knowledge of materials, thermal comfort, building physics, and environmental impact of construction.
Background: a long term interest in sustainability led me from my past career making pots and building kilns to a low-energy self-build retrofit project. It was a rapid introduction to sustainable construction, and the factors affecting material and design choices.
From there I went on to an MSc in Sustainability Adaptation and the Built Environment, from the Centre for Alternative Technology’s (CAT) inspiring Graduate School of the Environment. I have returned regularly to CAT as a visiting lecturer and workshop leader on the MSc and MArch programs.
