Council policy - promote sustainable design and construction Design for energy efficiency -reducing C0 2 & fuel poverty Promote use of environmentally friendly materials -reducing pollution and environmental damage Require sustainable accredited timber -avoids deforestation / loss of biodiversity, etc
Ethelred tower blocks Ward, Brittany and Elkington Required major improvements Decent homes work needed
Ethelred’s problems Spalling concrete Ineffective heating and ventilation Generic heating and hot water charge for residents but high energy costs for Lambeth as landlord Socio-economic study May 2009: –53% of respondents suffered condensation –38% could not keep their homes comfortably warm due to draughty windows.
Funding Lambeth had prior experience of carbon reduction projects Positive track record on sustainability helped us secure additional funding –Government Office London £6.8m
Sustainable design and construction Holles house refurbishment- proven 50% energy use reduction via a range of sustainability measures
Sustainable legal timber Fairfax House – the first construction project in Britain to be independently certified by the Forest Stewardship Council for its use of sustainable timber.
