Lighting

• Use occupancy sensors to control lighting offices, conference rooms and even whole floors while not in use. These inexpensive devices can reduce lighting costs by up to 40%.
• Use an ENERGY STAR® labeled LED exit sign; it can last up to 25 years and save you almost $25 per year.
• Replace high-use incandescent light bulbs with compact fluorescent lights (CFL). CFLs use up to 75% less electricity to produce the same amount of light.
• Dirt can absorb as much as 50% of your lighting, so clean your fixtures on a regular basis.
• Open the shades and enjoy natural light on mild-temperature days.

Electronics and Equipment

• When it's time to buy new computers, consider switching to laptops. They use up to 90% less energy than desktops.
• Turn machines off when they're not in use.
• Screensavers can increase energy costs by up to $50 a year. Look for other power management features in the control panel for Windows or in System Preferences for Macs.
• Choose energy-saving ENERGY STAR® products whenever possible when upgrading or purchasing new office equipment.

Utilities and More

• Set water heater temperature to 110-120° to prevent scalds and save energy.
• User water-saving faucets, showerheads and urinals.
• Keep exterior doors closed as much as possible.
