DIY 1960s EnerPHit retrofit: CB1

DIY 1960s EnerPHit retrofit: CB1

Fri 15 Oct 2021, 7:00pm – 8:00pm

Meet your host, Wookey: Wookey began work on this retrofit in 2007. He has been undertaking the retrofit in stages and aims to have everything complete by 2025. By retrofitting in stages, Wookey has been able to reduce costs, research the different eco-measures and complete much of the work himself.

The original aim for the renovation was to upgrade the house to The Association for Environment Conscious Building’s (AECB) CarbonLite standards. However, they have now upgraded their ambition to reach EnerPHit certification (quality-approved energy retrofit with Passivhaus components).

Wookey says: “To prepare for the renovations I did a lot of research. This enabled me to do a lot of the work myself and minimise the cost of contractors.”

This tour is a great opportunity to hear from Wookey about the pros and cons of a longer-term DIY retrofit undertaken in stages.
