The National Computer Center (NCC), provides large-scale computing services for EPA nationwide.

Sustainable Features

  • NCC received the U.S. Green Building Council’s LEED® Silver for New Construction (version 2.0) certification in January 2005.
  • The NCC building was awarded the ENERGY STAR® in 2015 with a score of 76.
  • NCC meets the Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings due to its existing LEED certification.
  • An extensive, third-party review of the data center’s operating conditions resulted in EPA shutting off six of the facility’s 13 computer room air conditioning units, while still meeting the sensitive cooling needs of the computer equipment. EPA also optimized and diversified the location of energy-intensive equipment to better match heat loads and cooling capacity.
  • Energy-efficient lighting includes high-efficiency fluorescent lighting, motion sensors, daylight dimming sensors and manual override switches.
  • Variable speed motors, fans and pumps meet actual energy demand and therefore prevent energy waste. Outside air economizers reduce energy costs by bringing in outside air when the temperature and humidity meet acceptable levels.
  • A building automation system (BAS) controls temperature, pressure, humidity, electrical systems, computer room cooling units, cooling and heating equipment, maintenance indicators, lighting and security.
  • A 100-kilowatt, integrated roof power system installed on the roof of the NCC is one of the largest photovoltaic (PV) installations on the East Coast. The system's PV cells are also backed with foam that increases the building roof's thermal insulation.
