CPD for Meshwork: Fabric-First Retrofit of a Victorian Terrace
How House for Zola, Camberwell achieved A++ performance and 66kgCO2e/m² through a fabric-first retrofit & minimal steel use.
Meshwork recently asked Andy to present an online CPD session for their members on the subject of retrofit, sustainability and how Andy Matthews Studio approaches these types of projects. The session demonstrates that a clear and pragmatic approach can achieve an A++ carbon rating of 66kgCO2e/m2, exceeding the current LETI 2030 target.
The session covers the following topics and uses two of our completed projects as case studies.
Fabric-first retrofit of Victorian and Edwardian terraces
Delivering LETI-aligned performance on small residential projects
Reducing demolition, steel and embodied carbon in extensions
Working with joinery, windows and details that support performance
Case study one - Flatrofit
Refurbishment of a ground floor purpose built Victorian flat in Streatham. There were issues with a large thermal envelope, solid masonry walls, a draughty floor void, and heat loss to the flat above. The study shows how we approached our first retrofit, researched internal wall insulation and WUFI calculations, found a place for PV panels, and delivered a meaningful scheme with a big impact.
Case study two - House for Zola
Refurbishment and extension of a Victorian terraced house in Camberwell. There were similar issues to previous properties we had worked on in terms of thermal performance. We developed a series of options to achieve an appropriate area of new build and worked with the existing fabric where possible. A strategy based on efficiency and working with the budget resulted in a high quality retrofit which achieved an A++ carbon rating of 66kgCO2e/m2, exceeding the LETI 2030 target.
