A comprehensive energy efficiency and conservation plan can save significant amounts of money at a commercial facility. There are many effective techniques that can be applied, but one of the most effective is also one of the most basic: start with the equipment and devices that use energy and replace them with more efficient models. Even if done little by little over time, the cumulative effect will be ever-diminishing energy use and ever-increasing savings. When you're looking for products that meet these qualification, find devices that carry the Energy Star label and certification.
