9 Urban Metabolism Organic model for thinking about material and energy flows in cities dates to 1965 (Wolman, A.)(1965). The metabolism of cities. Scientific American,

10 Urban Metabolism Reduction in potable water demand through recycling Waste water Additional Land Area for Food production Reduction in potable demand through rainwater harvest Water Non-potable water demand (treated wastewater) Agricultural production (External Area) Additional Land Area for Biomass production Potable water demand Passenger Transport distance (based on density) Land Use Schedule Travel demand Passenger Transport Generation of biogas Fuel source energy supply (rice husk) Biomass / Biofuel production (External Area) (a) Supply of housing (a) Employment demand Freight transport distance (based on density) Energy demand by type Production of sewage effluent (b) Social infrastructure demand POPULATION Per capita energy demand excl. transport / logistics Employment generated (external): Agricultural production Employment generated (external): Biomass production Fuel source energy supply Social Reduction in energy demand through embedded renewables Waste output Energy Energy recovery from tonnes / composition waste incineration(?) Employment: Recycling(??) Land area required for turbines Demand for consumables (food, etc) Consumption (Food, goods, etc) Energy for freight movement Waste management Tonnes of goods moved Freight movement (Logistics) Tonnes of waste moved Wind Turbines Energy from Wind

12 Beyond VMT in Land Use In One Project: VMT related GHG reductions: 46% Building energy related GHG reductions: 54% (i.e. greater than the VMT related emissions reductions).

13 Beyond VMT in Land Use In One Project: VMT related GHG reductions: 46% Building energy related GHG reductions: 54% (i.e. greater than the VMT related emissions reductions). and this did not include further benefits from embodied GHG in the improved water and waste systems (often better in infill locations) or the protected bio-mass sequestered in undeveloped alternative sites such as prime ag land and watersheds.

14 Progress towards best practice sustainability Trajectory Normal practice Best practice No attention Acknowledge problems Design principles Management process Just get the job done Legal Compliance We re wasting resources. Our reputation is at risk. Ad hoc attention to sustainability issues. We design individual strategies, each with sustainability elements. We use integrated, holistic design to optimise sustainability Early Adopter Market Leader Global Leader
