The U.S. and India have teamed up through the University of California Berkeley-India Joint Leadership on Energy and the Environment (BIJLEE) to develop new energy-saving appliances, market strategies, and cost-effective energy reduction techniques. Of their various programs, I really found the white roof concept fascinating.
Per Jayant Sathaye, Co-Director of the US-India Joint International Program with Berkeley University, the use of white roofs has proven to substantially lower building temperatures and their associated costs and CO2 output through associated energy consumption reduction. Dr. Sathaye indicated that “If you have 100 sq meters of gray roof and transfer to white, you offset the emission of 10 tons of CO2. If we convert all possible rooftops to white roofs, we would save 24 Gigatonnes of CO2 emissions, the equivalent of pulling 300 million cars off the streets.”
For those of you studying green buildings, energy efficiency, or energy policy, this might be something to look at, as companies such as Walmart are already beginning to implement this strategy and saving a great deal.
Additionally, the organization is looking into creating the market and supply chain necessary to develop the next wave of smart appliances. The industry is moving towards minimal emission and post-life use appliance development, and India has even implemented a much more comprehensive Energy Star rating system to help consumers of both appliances and office space make more conscious purchasing decisions. Perhaps this would be a good thing for SNRE BEC students to look into.
A great session overall, and I would be glad to discuss more upon my return for those interested in these projects.
