Centralized Cooling System in HP Data Centers

Bangalore
Summary: 
Hewlett Packard has made a change in Bangalore that is now saving the company 2 million annually. To save on data canter cooling costs, 14 separate data centers were consolidated into one 70,000 square foot facility. Traditionally, data centers are pumped with cool air, causing energy waste . HP's data center has 7,500 temperature sensors that are part of a centralized system which allow for spot cooling, which saves approximately 40% of the cooling energy.
Description: 
This solution works because it approaches data center cooling as a dynamic energy system rather than as a bottomline cost. It saves a great deal of energy, and each sensor stops about a ton of carbon dioxide from escaping to the atmosphere each year. A simple cost-benefit analysis would show those with decision-making power that this project ought to be implemented.
Extended Answers
Finance - Did this climate solution require funding?: 
Yes, but it also caused significant savings.
Benefits - Have the carbon savings of this solution been quantified?: 
This project has saved 7,500 megawatt hours of electricity and has reduced the amount of carbon dioxide escaping into the atmosphere by about 7,500 tons.
