Lighting is the single largest electricity user in commercial buildings.
Local government officials looking for ways to save money should consider retrofitting their existing facilities with energy-efficient lighting. Of course, you may also realize greater savings by requiring use of energy-efficient lighting in new buildings. And don't overlook the savings you can achieve by retrofitting street lights for greater energy efficiency. Our studies show that the most efficient lighting option is also the least expensive option on a life-cycle cost basis. Our experience in Montgomery County shows that making buildings energy efficient requires more thinking, not more money.
