Summer Energy Conservation

July 9, 2007

With temperatures expected to climb into the 90s early this week, Columbia University Facilities would like to take this opportunity to remind you what we are doing to reduce energy consumption during hot summer months and what you can do to help.

During the day, we are optimizing the use of our central plant steam driven chillers to cool buildings and minimizing the use of our electric chillers in order to reduce the total electric load on our system. During the night, we are "pre-cooling", or cooling buildings overnight, 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 speed to the lowest setting possible
  • Keep exterior doors, windows, shades and blinds closed as much as possible
  • Turn lights and appliances off when not needed

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 to 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
