Carbon Neutral Supply Side
Future
A. Add to the Grid with large scale renewables
(wind farms, solar farms, geothermal, ocean and tidal)
B. Sequester carbon (clean coal)
C. Find new technologies to remove carbon from the
atmosphere
D. New biofuels for transportation
Demand Side
A. Reduce demand from central infrastructure through
conservation and renewables equals:

• New building project, development and major
renovation meet a fossil fuel energy-consumption
performance standard of 50% of the regional (or
country) average for that building type.
• That at a minimum an equal amount of existing
building area be renovated to use 50% of the fossil fuel
energy they currently consume.
• New Buildings-50%
2010 – 60%
2015 – 70%
2020 – 80%
2025 – 90%
2030 – Carbon Neutral
(no fossil fuel energy to operate)

©2007 by the Regents of the University of California Made-In-China “Eco-Blocks” Harrison Fraker, FAIA Dean College of Environmental Design, UC Berkeley
- 11. China is efficient at building housing on a mass scale to meet this rate of
growth – 11 million new ‘SuperBlock’ housing units are built each year
©2007 by the Regents of the University of California Made-In-China “Eco-Blocks” Harrison Fraker, FAIA Dean College of Environmental Design, UC Berkeley

- 13. …and the natural environment has become significantly degraded
©2007 by the Regents of the University of California Made-In-China “Eco-Blocks” Harrison Fraker, FAIA Dean College of Environmental Design, UC Berkeley
- 14. The need for sustainable development is recognized…
quot;We will endeavor to develop a circular economy, lower energy and resources
consumption and build a resource-conserving and environment-friendly society and
ensure sound balance between economic development, population, resources and
environment.quot;

• Mass replicable
• Economically viable
• Resource self-sufficient – water, waste, energy
• 100% wastewater recycled on site
• 75%+ reduced potable water demand
• 100% on-site renewable energy generation
• Encourage journeys by foot, bicycle and transit
• 40% to 60% site area to be green space
