No matter what size your office is, by making just a few small changes you can make a big difference in your energy usage. Talk it over with your colleagues and employees. You'll be surprised how many would like to help the environment, and have already made the changes in their homes.
Turn off all lights and unplug the electronics when you leave the office for the night. Computers and other equipment use energy even when they're switched off. To make it easy, plug all your appliances into a power strip and you'll only have to flip one switch at the end of the day.
When it's time to buy new computers, consider switching to laptop computers. Laptops use up to 90% less energy than a standard computer.
Also, eliminate screensavers, which can increase energy costs by up to $50 a year, and set computers to hibernate when they're inactive. Want to save more? Look for other power management features - on the Control Panel for Windows or in System Preferences for Macs.
When upgrading or purchasing new office equipment, choose ENERGY STAR® products whenever possible. Most major brands carry energy-saving models marked with the ENERGY STAR® label.
Keep your exterior doors closed as much as possible. This includes reception, office, and all freight doors. And if you have windows that can open, the same recommendation applies.
