Bright Lights, Big savings

摘要

There is no greater energy glutton in commercial construction than lighting. Nothing, not even heating or cooling, comes close.rnFor much the same reason, lighting is commercial construction's single greatest source of energy savings, assuming that owners exercise their options.rnThere is no reason not to, now that new generations of lamps and ballasts can cut lighting costs by 30 to 60 percent, all but ensuring prompt payback. In fact, lighting upgrades have been dubbed the low-hanging fruit of energy-conservation programs since they can be performed with relative ease and require little, if any, maintenance once the upgrades are completed.
