Raising Retrofit Standards
January 24, 2022
Our team is currently working on a number of residential retrofit projects.
The retrofit process aims to improve the levels of energy efficiency and sustainability of existing homes to tackle common issues of dampness and mould, poor thermal performance, drafts and high carbon emissions from heating of space and water.
There are a number of retrofit guides and certification routes we are working with. These include EnerPhit (Passivhaus Standard Retrofit), Leti's (London Energy Transformation Initiative) Climate Emergency Retrofit Guide and PAS 2035 retrofit certification.
A recent example of a retrofit project is an end-of-terrace family home in Bristol.
The retrofit strategy includes improving the thermal envelope with the following features: new external wall insulation (EWI); insulation of the existing ground floor and roof; the replacement of windows and doors with highly efficient triple glazing; the replacement of mechanical and electrical systems with new ventilation and heating systems; the addition of PV panels for generation of electricity; and an air source heat pump (ASHP) for space and hot water heating.
We are working alongside a PAS 2035 retrofit assessor and an accredited installer of energy efficiency measures in order to achieve PAS 2035 standard and turn this house into a highly efficient and comfortable family home.
We believe that making our existing housing stock more sustainable and healthy is just as important as building new highly efficient buildings in attempt to tackle the current housing and ecological crises.
