View Sustainability Report

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 also began procuring renewable energy and installing fuel cells in 2017 and are committed to continuing this commitment into the future.

Data Center Efficiency

We follow a proactive maintenance and upgrade strategy to preserve and further improve the efficiency of our existing infrastructure.

Examples in 2017 included:

  • A chiller replacement in our LA2 facility: 16 Gigawatt hours (GWh) projected annual reductions
  • Optimization of the economizer and sequence of operations at our SV7 facility: 2.1 GWh projected annual reductions
  • An upgrade of controls at our SV4 facility: 0.7 GWh projected annual reductions

Renewable and Alternative Energy

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. In June 2017, we procured approximately 4 MW of 100% wind-sourced Renewable Energy Credits (RECs) for our NY2 data center. This will cover NY2's electricity needs until the end of 2020, equaling over 90,000 avoided tons of CO2e emissions. In the future, we will install 1.5 MW and 4 MW on-site fuel cells at our SV2 and BO1 sites. These projects are projected to reduce 13 million lbs of CO2 annually.

* Scope 1 emissions are from natural gas consumption. Refrigerants are a significant source of emissions for us as well. We are currently putting system enhancements in place to enable us to track and report emissions from refrigerants in the future.
** Market-based emissions, considering 19,000 MWh of purchased renewable energy credits; location-based emissions amount to 262,000 metric tons of CO2 e.

Water Use

We primarily use water to cool our data centers. Sometimes that means we must increase our water consumption in order to achieve higher energy savings. We always strive to balance the use of both water and energy in the most efficient way.

To conserve potable sources in drought-prone California, we use recycled water at the SV4 data center in Santa Clara. The water is treated to high standards set by the California Department of Public Health and is delivered to us by the city in separate pipelines. We utilize it for cooling, landscaping, and in water closets.

Rainwater is a renewable natural resource that can also increase the resilience of our data centers. In 2017 we started working towards commissioning an 80,000-gallon collecting cistern on our VA2 data center. It will not only act as a secondary water source but also facilitate a seamless transition to rainwater should an issue occur with our city water. The cistern is expected to save about a half million gallons of water per year.


Recycling Foam Plastic

Our employees at NY2 in New York turned a waste challenge into a success story. Most of the waste we encounter at our data centers is cardboard and foam plastic, both of which are light but voluminous. Foam is also tricky to recycle and often ends up in the general waste stream. Our NY2 team worked with a third-party vendor (Premier Facility Management), to purchase our own on-site compactors for aluminum and plastic, a cardboard baler, and a foam plastic densifier. These machines significantly condense the material and turn them into bricks and bales. In the case of the foam, the volume is densified by 90%. Our third-party vendor then collects the material for recycling or repurposing.
