LADWP, CoreSite announce major energy savings

CoreSite Realty Corporation (NYSE:COR), a premier provider of secure, reliable, high-performance data center and interconnection solutions in major US metropolitan areas, celebrated CoreSite´s energy efficiency savings this week in an award ceremony with the Los Angeles Department of Water and Power (LADWP), the company said.

CoreSite, one of the nation´s premier data center corporations and a key customer of the LADWP, received a nearly USD 3 million rebate earlier this year for energy efficiency upgrades at its LA2 facility in downtown Los Angeles. LADWP´s Custom Performance Program provided the incentive to help CoreSite implement an extensive cooling system retrofit that has yielded more than 9.8 million kWh of energy savings annually.

In a recent expansion of its LA2 data center, CoreSite recognized an opportunity to modernize its cooling systems. The facility was previously operating with four small cooling systems that operated year-round, day and night, to remove server heat from downtown Los Angeles´ largest data center. CoreSite consolidated the four units into a single large system that incorporated the best cooling technology in the market and capitalized on efficiency options made possible by the size of the new plant.

As part of the project CoreSite took four live systems and converted them without interrupting cooling service. Due to space constraints at the LA2 facility, CoreSite´s challenge was to place the entire system into an area the size of a dozen parking spaces without changing the architectural appearance of the historic postal annex. The project also required the installation of five 40,000 gallon storage tanks to ensure cooling could not be interrupted if the water supply was lost to the site.

CoreSite supplemented electrical power with new backup generators that would ensure power could not be interrupted. With expert preparation, CoreSite was able to complete the project in under six months. CoreSite is now able to provide enhanced capacity and greater reliability at its LA2 data center, all while using less energy.
