Striving for Sustainability

The O’Connor Recreation Center strives to be environmentally sustainable.

  • With nearly 1,400 panels, the solar array on the Recreation and Athletic Center roofs is the largest of the seven Hopkins solar installations. The array produces 450,000 kWh or clean electricity yearly — enough to power an average home 41 times over!
  • The arrays also reduce greenhouse gas emissions. The Recreation and Athletic Center array eliminates the emissions of over 600,000 pounds of greenhouse gases per year.
  • The two water refilling stations provide exceptionally clean, filtered water and eliminate the need to buy plastic disposable water bottles. Water Refilling stations are located in the Track Stretching Area and outside the Evans Multipurpose Room.
  • Recycling and compost bins are located throughout the facility.
