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
