Low Energy Arts & Crafts Retrofit

Retrofit of a 1909 home employing novel low energy technologies

The retrofit of this 1909 home was designed to demonstrate pioneering low energy building technologies and materials. Completed 10 years ago and achieving an 81% decarbonisation, every aspect of this home - from building materials to appliances and fixtures - has been chosen with sustainability in mind. A timber-framed Passivhaus level extension has been added to the rear of the home, with glazed mono-pitch roof to capture energy alongside thermal mass components to store the heat. This is the first house to utilise Passivent's iHybrid whole house mechanical ventilation heat recovery (MVHR) system. The first installation of Aerogel (Spacetherm) External Wall Insulation. The first ever integrated solar powered rainwater harvesting system.
