Save Energy This Summer

July 6, 2010 

With New York City experiencing high heat and humidity this week, Columbia University Facilities would like to remind you what we are doing to reduce energy consumption during these hot summer months and what you can do to help.

During the day, we are optimizing the use of our steam chillers to cool buildings and minimizing the use of our electric chillers in order to reduce the total electric load on our system. At night, we are "pre-cooling" buildings, which reduces energy demand during peak daytime hours.

We also have Facilities staff on hand to provide fast response to service requests and emergencies. Our Facilities Service Center (x4-2222) is prepared to handle increased client calls.  

You can help Columbia conserve by following these easy steps:

  • Turn off air conditioners when a room is unoccupied
  • Set air conditioner fan speeds to the lowest setting possible and keep thermostats as high as possible for energy conservation
  • Keep exterior doors, windows, shades and blinds closed
  • Turn lights, appliances and electronics off when not needed
  • Contact the Facilities Services Center at x4-2222 with any issues or concerns. We are here to help.

Stay safe and cool this summer with these tips from the American Red Cross:

  • Dress for the heat. Wear light lightweight, light-colored clothing. Light colors will reflect away some of the sun's energy. It is also a good idea to wear hats or use an umbrella.
  • Drink water. Carry water or juice with you and drink continuously even if you do not feel thirsty. Avoid alcohol and caffeine, which dehydrate the body.
  • Slow down. Avoid strenuous activity. If you must do strenuous activity, do it during the coolest part of the day, which is usually in the morning between 4:00 a.m. and 7:00 a.m.
  • Stay indoors when possible
