One of the simplest ways to reduce energy consumption in any building is to turn the lights off when they’re not needed. While this is easy enough to do at home, it’s a little trickier to manage in the workplace, where there are more people present and many light fixtures to adjust. An article on Care2 by Diane MacEachern recently advised consumers to think about the different bulbs they use and how often to turn them off.

According to the article, some bulbs are more sensitive to being switched on and off than others. Compact florescent lightbulbs (CFLs), for example, save more energy generally but don’t last as long if they are turned on and off too frequently. By contrast, halogen bulbs and LED lights can be shut off at will without losing any functionality.

The source also cites official government guidelines for using CFLs, including timing it so that bulbs can be used for longer periods of time. While only switching them off for long periods takes practice, it should ultimately lead to more efficient use of resources.

“The U.S. Department of Energy recommends that, if you will be out of a room for 15 minutes or less, leave it on,” MacEachern wrote. “If you’ll be gone longer than 15 minutes, turn it off. Because not all CFLs are equal, choose ENERGY STAR certified CFL bulbs for the highest quality light as well as bulbs that will illuminate most quickly.”

These green office solutions don’t just help reduce a business’s carbon footprint: They also lead to financial savings overall, as your business spends less on replacing its bulbs and takes a more efficient approach to energy use.
