Efficiency Focused

CoreSite employs data center cooling best practices and optimal power designs to provide our customers with high-performance, reliable, and energy-efficient data center solutions.

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.

Data Center Efficiency

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

Examples in 2019 included:

  • Rather than build a separate condenser water system, we worked with the LA1 landlord to tie into its existing high-efficiency cooling system. This enables CoreSite to leverage existing cooling infrastructure for this space and increased system utilization in turn increases the system’s efficiency.
  • We added new software to our existing digital infrastructure to better monitor and respond to temperature changes at our NY2 data center. This allows us to make temperature adjustments in real time and reduces the total energy needed for cooling.
  • We conducted an electrical equipment upgrade at our DE2 facility including electrically refeeding equipment, hardening our infrastructure and improving our efficiency.

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. 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.

* Emissions include scope 2 emissions from data center electricity and scope 1 emissions from natural gas usage (less than 1%). 2017 location- based data were adjusted using updated 2017 eGRID emission factors. CoreSite relies on GHG accounting standards and tools, which continually refine their emission factors based on growing knowledge and availability of more recent measurements. We continue to evaluate the disclosure of market-based emissions as the methodology evolves.

Water use

Water Tower

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.

Waste and recycling

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.
