We are proud to be a leading provider of secure, reliable, and efficient data centers-efficient for our customers, for CoreSite, and for the environment. As an energy-intensive business, we believe that efficiency begins with a facility design that features state of the art systems that help us reduce our environmental impact. We installed fuel cells at one of our data centers in 2019 and are committed to continue this commitment into the future.
We follow a proactive maintenance and upgrade strategy to preserve and further improve the efficiency of our existing infrastructure.
Examples in 2019 included:
We recognize the crucial role renewable and alternative energy will play in balancing the immense energy needs of the data center industry, as well as our customers' interest in carbon-neutral data storage. Our NY2 data center utilizes 100% renewable energy as a result of our procurement of 100% wind-sourced Renewable Energy Credits (RECs), which cover all of the site’s usage, approximately 37,000 MWh in 2018. We’ve installed a 1.5 MW fuel cell at our SV2 site.

We primarily use water for the cooling of our data centers. Therefore, to save energy related to cooling, we must occasionally increase water usage. We are continuously working to balance our energy and water usage and particularly work to reduce our use of potable water.
For example, in May 2019, we installed a 120,000 gallon cistern at VA3 that we use to reclaim all water collected on our roofs from rain events. The water collected via roof drains is passed through a four-pass filter system, treated with UV lights to disinfect, and pumped into our main 260,000 gallon storage tank to be used in our cooling tower. We also used 46M gallons of recycled water at our Coronado Stender Campus in Santa Clara, CA. Our water use strategy reduces our freshwater consumption and increases our operational resilience.
At the end of 2019, CoreSite began an initiative to consolidate waste management under a single vendor. This vendor will manage all aspects of waste management, from local vendor selection, pricing, reporting, and even dispatching. By moving to a single, specialized vendor, CoreSite is able to reduce cost through vendor selection and volume pricing, issue one payment per month compared to more than 25 payments prior to consolidating under a single vendor, analyze waste streams and site trends for savings opportunities and efficiency enhancements (balers, compactors, etc.), increase recycling amounts, and track all waste.
During 2019, CoreSite recycled 118 tons and 3,709 yards of material. The two different units of measure are due to some vendors tracking materials by weight and others tracking by volume. To further elaborate on those numbers, CoreSite produced 861 tons and 6,997 yards of waste and recycled 14 percent and 53 percent of that waste respectively. The majority of our data centers’ recycling is cardboard and foam, which has a high volume and low weight relative to landfill trash.
