Pathway to Urban Sustainability: A Transformative Response to Climate Change

slide-7
SLIDE 7

How can millions of ageing, inefficient homes be used to:

v enable a zero-carbon, low water-use future, v eliminate GHG emissions, v reduce stress on potable water, stormwater & wastewater infrastructure, v mitigate urban heat island extremes, v meet or surpass renewable energy goals

slide-8
SLIDE 8

By aggregating common-pool resources on a block scale:

v energy v water v wastewater v food v transportation fuel v Today, sourced individually from a distant location v Tomorrow, can be pooled collectively & locally at huge savings.

Block-scale retrofits can solve the integrated design problem of greening our cities

  • 1. Energy
  • 2. Transportation
  • 3. Water
  • 4. Wastewater
  • 5. Microclimate
  • 6. Food
