- 8. Britain – Summer 06 • SE had less potable water than the Sudan • Water consumption rising by 1% per annum • Average household demand has rapidly increased we use 55% more water than in 1980 (150 litres pp/pd) • Hosepipe bans for 18 months in some areas
- 9. Britain - Summer 07 Two thirds of the floods in Summer 07 were nothing to do with rivers breakingtheir banks.The floods were caused by storm surge in drainagesystems which wereincapable of coping with the volume of water.
- 10. Construction as a target • Carbon Dioxide Emissions – Buildings 46% – Domestic 27% • Water demand rising – 56% - of water supplied is domestic • Buildings significant in terms of natural resources – Materials in their construction – Construction waste is a significant waste stream • Demand for housing continues to grow, meaning increasing pressure to find land for development
- 11. Standards • Legislation, Regulation & Reporting Stern Review The application of BREEAM excellent standards, or equivalent, to all Government new builds and major refurbishments All new homes built by RSLs, or others with Housing Corporation funding, will comply with Level 3 of the Code

- 17. The Big Challenge - Existing • Domestic Buildings – 26 million homes – 50% of homes over 50 years, 20% over 100 years – 160,000 new homes each year, just 20,000 demolished – At least 80 per cent of the homes that will be standing in 2050 have already been built – Will have to last 1,000 years at current clearance rate – 37% fail Decent Homes Standard • Non-domestic buildings – 70% of non-domestic buildings pre-date Part L (1985) – 40% of buildings in 2050 will pre-date Part L (1985) – New build represents 1-2% of floor space in any 1 year

- 19. Aims Results/Targets Strategies Carbon & Energy Efficiency Significant reductions in energy demand and supply of energy through carbon intensive means Maximising the envelope efficiency of the building Suggest appropriate systems Look at on and off site resources to limit use Water Efficiency Reduce demands for potable water Reduction of waste water Reduce demand through water efficient products Minimise drainage implications Harvest rainwater Using sustainable materials Minimisation of embodied energy Life cycle assessed products Natural materials and recycled content Identify roles of materials and suggest alternatives Understand sources and implications Coping with climate change Recognise the potential impacts of future climate change Assess effects of peak weather events Describe potential local scenarios and assess effects on the building and surrounds Positive social contribution A building that will be durable and attractive, improving quality of life Develop community engagement plan to define inclusive strategy for access and use Sustainable operation Easy & efficient use which will reflect performance though monitoring & measurement Identify maintenance requirements Minimise waste outputs Train users & managers
- 20. Basic Strategy - 1 Envelope of the building Orientation of the building Products which optimise performance In use In controlling use Design the building to minimise energy demand
- 21. Basic Strategy - 2 Local renewables Solar thermal Heat Pumps Biomass CHP Photovoltaics Remote renewables Green Tariffs District Heat & Power Large Scale When energy use is unavoidable try to use renewable sources
- 22. Basic Strategy - 3 Strive to use products with the lowest environmental impact Low embodied energy High recycled content Water efficient Ease of installation Durable in application Maximise use of local natural resources Easy to maintain Supply Chain
- 23. Materials Cycle Long term sustainability Short term availability Ongoing maintenance Practicality & economy End of life cycle plan Efficient production and delivery Embodied energy Sustainable supply chain Durability, spares & long term stability Recycle or disposal
