Collaborations with Berkeley Lab's Building Technologies Department on technologies such as advanced windows, day lighting, heating/cooling systems and demand-side management are in the works.
When India first started building information technology parks to attract Western companies, they were built to Western standards. "Now they're saying, 'what can we do to improve that model?'" said Sartor. "They're in a position to be the standard-setter rather than standards follower. We've been talking to them about, instead of building architecture with a capital 'A,' that's glitzy with lots of glass, we're suggesting they build their new buildings with a capital 'S' for sustainability. India has the opportunity to change the paradigm. They're going to building a lot more buildings than we will here."
Separately, Berkeley Lab conducted a one-year experiment in 2006 in Hyderabad on two nearly identical buildings: one with a white roof and the other with a standard roof. The result was a 5 percent reduction in electricity consumption in the building with the white roof. That was enough to convince New Delhi's Chief Minister to approve mandatory white roofs for all new government buildings this past July. "She saw the benefits immediately and was very enthusiastic," said Sathaye. "That was a big step forward."
The explosive growth of the Internet and the related use of digital media digitization of everything have caused a massive expansion of data centers around the world. A 2007 report to the U.S. Congress noted that data center energy use in the U.S. doubled between 2001 and 2006, accounting for 1.5 percent of total U.S. electricity consumption in 2006. The situation in India is similar but even more significant, given that its economic growth is based largely on the information technology industry.
