Hammarby’s battery of recycling 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 Vacuum-powered waste extraction takes recycling to sorting depot where biogas is created 5 JULY 2007

“The Hammarby model” Target is to use 50% less heat and water than Sweden’s Building Regulations Stockholm has licensed “Model” to other cities, notably Vancouver 5 JULY 2007

Sweden’s low-carbon strategy ‘Bought energy’ in buildings must be lower than 100kWh/m2 a year by 2010 Premises to be energy rated by 2007 20 demonstration projects a year 5 JULY 2007

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 5 JULY 2007

CSH’s minimum targets for water and energy consumption CODE LEVEL 1 2 3 4 5 Energy (% reduction over ADL1 2006) 10% 18% 25% 44% 69% Water (daily usage in litres for each bedspace) 125 118 105 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 Show slides of Nepal With level 6, 100% reduction as house becomes net producer of energy 5 JULY 2007
