How District Energy Works

District energy is an innovative and resilient energy solution that uses a centrally located facility, or facilities, to generate thermal energy—heat, hot water or chilled water—which is then transported through highly insulated underground pipes directly to nearby buildings, avoiding the need for boilers, chillers and cooling towers in individual buildings. Watch the video to learn more about how district energy works.
