Houston writes in to let us know about an article he wrote about five green retrofits that electricians should be advocating for. It’s a good way to get new business and help the planet.
Daylight harvesting is the practice of reducing artificial light in a room when sunlight is available. According to a study performed by the NRC Institute for Research in Construction, it can reduce lighting energy costs by 20 to 60%. Call it â€œupsellingâ€ if you will, but electricians should pitch this retrofit to customers that are already relamping their homes and buildings.
A daylight harvesting system uses photosensors to detect light levels in a room. As sunlight becomes available, the artificial lighting will be reduced. When itâ€™s cloudy or becomes dark outside, the level of artificial lighting will increase.
Three other lighting controls worth mentioning here are dimmers, motion sensors and timers. These energy savers have been around for years, but they are just as relevant today as when they first came out. Homeowners looking for simple ways to reduce energy can install any of the above.
