Environmental efforts make Sibley Hospital a green leader

Produce garden With the help of the D.C. Beekeepers Alliance, Sibley has set up four beehives on one of our green roofs to give imperiled bees a home.

Sibley Memorial Hospital is committed to taking care of the planet as we care of our patient. Building B, the new patient tower opened in 2016, was built with the environment in mind. Building features that reduce energy, cut waste and employ environmentally friendly materials have earned Sibley recognition as one of the 50 greenest hospitals in the nation. Both Building B and Sibley's Radiation Oncology Center are LEED (Leadership in Energy & Environmental Design) Gold certified.

Sibley's commitment to nature extends beyond the buildings' walls, as well. The grounds contain multiple features to conserve and reuse water, and instead of lawns much of the campus is devoted to employee-managed vegetable, fruit and herb gardens. To aid the imperiled honeybee population, Sibley houses a number of hives on one of our green roofs. At the Building B dedication on September 23, 2016, Sibley was honored by the D.C. City Council with a proclamation recognizing the environmental features of the campus.

Produce gardenSibley's produce garden is sustained by runoff water from retention ponds.

Some of Sibley's environmental features include:

  • LEED Certification:
    • Radiation oncology center – LEED gold certified
    • Building B – tracking LEED gold
  • Green Roofs:
    • Two of the largest vegetative roofs of any healthcare facility in Washington D.C.
    • A total of 50,000 square feet (radiation oncology center: 23,000 ft; main tower: 10,000 ft; emergency department: 15,000 ft)
    • Vegetative construction prevents about 310,000 gallons of water from entering the storm water system every year
  • 4 beehives housed on one of Sibley’s green roofs aids local pollination
  • One of the largest gabion walls (a wall built out of stones and wire baskets instead of the customary concrete) in metro D.C., saving over 200 yards of concrete
  • 5 large rain/retention ponds covering over an acre that retains storm water run-off of Sibley’s surface parking lots
  • Vegetable, fruit and herb gardens sustained by runoff water from retention ponds
  • Cisterns with 40,000 gallon capacity harvest runoff rain water for lawns and plants that would otherwise end up in the city sewer system
  • As part of construction, existing large trees were relocated and dozens of new trees were planted
