Sustainability Tips



  • Turn out the lights every time you leave your office, empty common space, or any other area.
  • Use task-specific lighting.
  • Use compact fluorescent light bulbs (CFLs).
  • Turn off lights in unoccupied rooms.
  • Use natural lighting (sunlight) rather than turning on the lights.


  • Do not use screensavers.  Set monitors to enter power save mode.
  • Turn your computer off at the end of the day.
  • Set sleep mode on your computer and shut it down each night.
  • Choose a laptop over a desktop.


  • When the heat or A/C is on, keep external windows and doors closed.
  • Turn down the heat overnight when you are away.
  • Do not set your thermostat to extremes – it will not heat or cool the space any faster.
  • Turn on the ceiling fan – it helps circulate the air and keep the space cooler.
  • Move lights, appliances and machines away from thermostats.
  • Close the blinds on your windows during the cold months to keep heat in and cold out.
  • Move desks and cubicles away from windows.
  • Keep heating and cooling vents unobstructed. 
  • Close the air vents in rooms that are rarely used. 


  • Unplug all appliances and chargers when they aren’t being used.
  • Plug all appliances and chargers into a power strip that you can turn off with one switch.
  • Have the vending machine operator turn off the advertising light in machines.
  • Look for the Energy Star label when buying appliances, products and lights.
  • Share printers and fax machines with colleagues.
  • Keep your refrigerator fully stocked.
  • Set refrigerator temperature to 38˚F and the freezer to 0-5˚F.
  • Adjust water heater temperature to 120 degrees.


  • Use phone, internet and video-conferences when possible rather than traveling to meetings.
  • See something that is wasting energy?  Report it or fix it right away.
  • Suggest energy saving ideas for your department.
  • Acknowledge and show support for coworkers who are taking steps to save energy.
  • Join a Green Team, or form one yourself!


  • Print on both sides of the paper.
  • Set your printer’s default to double-sided (duplex) printing.
  • Use the blank side of any paper for scrap to take notes, jot down messages or for to-do lists.
  • Send, read and save documents electronically instead of printing them out.
  • Change your margin settings to 1” (or smaller!) on all sides of your document.
  • Ask companies to remove your name from their catalog mailing list to cut down on junk mail.


  • Recycle!
  • Buy recycled products and those with high post-consumer content.
  • Drink from the tap and refill a reusable water bottle instead of buying bottled water.
  • Carry a re-usable mug for hot beverages.
  • Bring reusable mugs and dishes to the office instead of using paper, plastic or Styrofoam.
  • Reduce the impact of your meetings and events by using real dishes, recycling and composting.
  • Support local growers and farmers—buy locally produced foods and products.
  • Take at least 2 reusable bags every time you shop.
  • Use rechargeable batteries.
  • Purchase products with Energy Star, Greenguard, Green Seal or Fair Trade certification.
  • Register to vote so you can create help change in environmental policy decisions.


  • Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline.
  • Do not idle your vehicle – it gets you 0 miles per gallon.
  • Walk, bike or use public transportation to commute to work at least once a week.
  • Carpool to work once a week.
  • Check into telecommuting, carpooling and public transit to cut mileage and car maintenance costs.
  • Combine errands into one trip.
  • Replace clogged air filters to improve gas mileage by as much as 10% and protect your engine.
  • Get regular engine tune-ups and car maintenance checks.
  • Keep tires properly inflated and aligned to improve your gasoline mileage by around 3.3%.
  • Use the grade of motor oil recommended by your car's manufacturer.
  • Reduce drag by placing items inside the car or trunk rather than on roof racks.
  • Clear out your car; extra weight decreases gas mileage.
  • Use air conditioning only when necessary.
  • Use cruise control on the highway.
  • Avoid high speeds. Above 60 mph, gas mileage drops rapidly.




  • Wash and dry full loads.
  • Wash your clothes in cold or warm water and rinse them in cold water. Use a cold water detergent.
  • Consider air-drying clothes on clothes lines or drying racks.
  • Don't over-dry your clothes. If your machine has a moisture sensor, use it.
  • Dry towels and heavier cottons in a separate load from lighter-weight clothes.
  • Use the cool-down cycle to allow the clothes to finish drying with the residual heat in the dryer.
  • Clean the lint filter in the dryer after every load to improve air circulation.
  • Periodically inspect your dryer vent to ensure it is not blocked. This will save energy and may prevent a fire.


  • Cook during temperate hours. Avoid cooking meals that require use of the oven on hot days.
  • Cook with a full oven. Prepare dishes together when possible.
  • Don't peek. Every time you open the oven door to look at the food, the oven temperature is lowered by 25°F to 75°F.
  • Keep oven and burners clean and kitchen ventilated.
  • Minimize or eliminate preheating. Don't preheat the oven if the food requires more than one hour of cooking time.
  • Turn off the electric range two to three minutes before the task is done and allow the residual heat to finish the job.
  • Use leftover heat as a food warmer. Ovens retain heat for up to 30 minutes after they have been turned off.
  • Use microwave ovens to save energy. Microwave ovens are about 66% more efficient than conventional ovens.
  • Use the broiler when possible. The broiler uses less energy, and preheating is not required.
  • Use the right sized pot on stove burners. A 6" pot on an 8" burner wastes over 40% of the burner's heat.
  • Cover pots and pans to keep heat in.
  • Double your recipe — and freeze half for later. Reheating uses less energy.
  • Defrost refrigerators and freezers before ice buildup becomes 1/4-inch thick.
  • Air dry dishes instead of using your dishwasher's drying cycle.
  • Scrape don't rinse dishes before loading the dishwasher. Pre-rinsing can use up to 20 gallons of water.


  • Take short showers instead of baths.
  • Turning off the water when brushing teeth or shaving.
  • Don't use the toilet as a wastebasket or ashtray - it wastes water every time you flush it.
  • Install aerating, low-flow faucets and showerheads with a flow rate of less than 2.5 gallons per minute.
  • Repair leaky faucets promptly.
  • Turn off ventilating fans within 20 minutes after you are done bathing to retain heated air.


  • Use outdoor lights with a motion sensor so they will turn on only at night or when someone is present.
  • Decorate with lighter colors that reflect daylight.
  • Consider three-way lamps; they make it easier to keep lighting levels low when brighter light is not necessary.
  • Turn off the lights in any room you're not using.
  • Use CFLs in all the portable table and floor lamps in your home.
  • Installing a skylight can provide your home with day lighting and warmth.

Heating and Cooling

  • Clean warm-air registers, baseboard heaters, and radiators as needed; make sure they're not blocked by furniture, carpeting, or drapes.
  • Don't place lamps or TV sets near your air-conditioning thermostat.
  • Clean or replace filters on furnaces once a month or as needed.
  • Use fans during the summer to create a wind chill effect. A ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.
  • Install a programmable thermostat that can be adjusted according to your schedule.
  • Close the damper when the fireplace is not being used.
