Lighting accounts for at least 28% of the energy used in the average office building. That translates to a pretty hefty chunk of the monthly budget. But, by making big and small energy-efficient updates, you can spend less and enjoy a more comfortable office environment.
Big Changes…
If you still use incandescent or outdated fluorescent overhead lights, it’s time for an upgrade.
LEDs use about 80% less energy to generate the same amount of light as incandescent light bulbs. They also last about 25 times longer. So, if you use incandescent light bulbs in your recessed cans, you should replace them with LED lamps or retrofits. LEDs excel at downlighting, because they’re naturally a directional light source. Today’s models have light output and color quality very similar to incandescent lights, so you might not notice the change until you look at your energy bill.
If you have older fluorescent lighting in your office (like T12s), you’re also not saving as much energy as you could. T12 technology is over 70 years old, and incidentally was taken out of production last year. If you exchange your T12s for T8s, you’ll use 45% less energy. Not to mention, the color temperature and light quality of fluorescent lights have improved dramatically over the past few decades, so new lights could be a huge morale boost for all the office workers.

Smaller Changes…
Office lighting isn’t just about what’s on the ceiling. To make sure you’re saving the most energy possible, you also need to take a critical look at the smaller light fixtures in the office. Continue reading »
