Energy Savings in Office Space Lighting

A recent article on office space lighting in tED Magazine states that “lighting is the biggest consumer of electric energy in commercial buildings, accounting for an average of 38 percent of consumption.”

Commercial buildings are often over-lighted, utilize inefficient light sources and pay high local energy costs – creating a space in the marketplace for significant lighting upgrades.

According to the article, “replacing older T12 systems with the latest T8 systems can generate energy savings up to 50 percent, depending on technology and light levels.” Using fewer lamps in over-lighted areas can also save on energy costs.

In the past, most office space lighting was designed to produce excessive light down to desk activities, while eliminating the glare on convex glass computer screens. With today’s technology, glare is seldom a concern, and more emphasis is being placed on human interactions.

Additionally, LED lighting is becoming more popular for office lighting as prices fall and and building owners focus on lifetime costs. Owners have also explored adding lighting controls as an upgrade. The use of occupancy sensors or a relay panel with a time clock ¬†allows lighting to be turned off when it’s not needed.
