Why don’t we fix our lights?

“Lighting is the single largest user of electricity in commercial buildings. It accounts for 38% of the electric bill—more than cooling, heating, and equipment. If you walk around a commercial building, you see why: The lights are too bright, they’re on for too long, and they illuminate vacant spaces.”
   Those two sentences are the opening paragraph of the Building Power feature that appears in our September issue, mailing Tuesday. I’d be willing to bet the $10 in my pocket that that paragraph describes 90% of the commercial buildings that are in use on any given day.
   Our concept of commercial building lighting is so antiquated, so ineffective, and so wasteful, that essentially all of it should be scrapped. We have lighting technology available to us today that will chop chunks of money out of our energy bills and do it with a rather short ROI, but we aren’t using it. Why don’t we see a nationwide effort to improve workspace lighting and cut energy costs?.—Gary L. Parr
