Energy Efficiency Buildings China Forum
Friday, 30 March 2007, Written by Julien   
The last two days, I have been taking part to the Energy Efficiency Buildings China Forum, organized by the World Business Council for Sustainable Development (WBCSD). WBCSD gathers many worldwide companies that care about environment. The aim of this forum was to define how to promote energy efficiency in Chinese constructions.

The main things I learned are:
  • The spread of Energy Efficiency Buildings is still a far target in China, as neither project developers nor public care about energy.
  • Energy Efficiency Buildings are just a part of the problem. The first step should be energy efficient city planning, that would reduce the need for transportation, and thus the amount of cars, roads, buses...
  • There is a massive need for people awareness.

I also heard some interesting figures:
  • for 1 ton of cement, 800kg of CO2 are generated
  • for 1 ton of steel, 2 tons of CO2 are generated
  • 80% of the energy consumed over the life of the building comes from the using period (the remaining 20% come from the construction and demolition phases),
  • traditional Chinese buildings are much more energy efficient than newly built buildings (!) (it is mainly because lifestyle and heating/AC systems are different)

You are caring about pollution? Then help promoting energy sobriety, and do not forget to walk your talk!

I just bought an electric bike. It's great for short term air quality but I'm not sure whether the recycling of the batteries pollutes a lot or not. I read an article statingthat manufacturers have efficient recycling processes, is it true?
