In an office building, there are all sorts of ways to reduce energy and water usage.
Using daylight and outside air can cut energy and HVAC costs. Aerators on sinks and low-flow toilets can reduce water usage. HVAC set points can be raised to participate in demand-response programs, power strips can be turned off at the end of the day to prevent equipment from still drawing power, and high-efficiency dishwashers in the breakroom can cut down on water usage.
