Key investor is Fortum, the city’s water company. Facility within development has 4 different water treatment processes
Foul water is purified and sludge used to create biogas. More than 1000 homes have been fitted with a cooker powered by bio gas making each home self sufficient in cooking fuel
Filtered water is piped to nearest agricultural production
Storm water is channeled through luxuriant hard landscaping feature into lakes and canals
Small hydroelectrical feature creates electricity for streetlighting
Heat recovery systems convert waste water in some blocks into space heating for common parts
Tap water is powered by solar thermal
PVs on some blocks

15. Why we had to move up a gear
EcoHomes was applied mostly to schemes built with Housing Corporation grant or on government land, such as EP, ie 1:10
Only David Wilson Homes among the top 10 has a corporate responsibility commitment to achieve ratings, with a target of 50% achieving good and 50% very good.
EcoHomes review is done at design stage, not completion
EcoHomes allowed trade-offs. Thermally inefficient units scored if they were built near public transport - whether occupants used it or not

Hurricane Katrina, the Asian Tsunami, Southern Sudan, Niger etc demonstrate how the environment can wreak havoc.
None of these events can be blamed on climate change but as climate change kicks in we are going to be increasingly prone to major natural hazards.
What these events demonstrate is how we are becoming increasingly vulnerable as we get richer and more dependant on the carbon economy.
We are becoming less and less adaptable and more vulnerable
The scale of devastation is growing exponentially and will threaten the economy – would it not be better to design sustainably in the first place
