Local Green Homes

Many local residents have made inspirational changes to their homes, cutting their energy use and carbon footprint and increasing comfort without sacrificing on their character.  Here are some examples below.  Note that most of these homes participate in our regular Green Open Homes events – these take place every year. During 2020 these tours are taking place virtually – check out our videos for the first two homes below.

Hawthorn Road, N8

A terrace house retrofitted as part of the UK Gov Technology Strategy Board funded “Retrofit for the Future”, the challenge was to achieve 80 % reduction in CO2 emitted. The first 18month monitoring shows a reduction of 79% CO2 emissions have been achieved. Where insulation was used internally, natural insulation and materials were specified to ensure the building fabric could continue to ‘breathe’.
  • Insulation;- sheeps wool internally to front walls and to roof, wood fibre board to party walls and polystyrene externally to rear walls and floor
  • lime plaster
  • high performance triple-glazed windows
  • a gas condensing boiler suppling a few     radiators and back up to a solar thermal roof panel for hot water
  • excellent air tightness of 2.08 air changes per hour, ensuring energy is not wasted unnecessarily
  • heat recovery ventilation system
  • heat recovery to shower waste
  • low water use fittings
