At a time when the economy makes many companies cut costs to maintain their profit margins, cutting energy costs remains one of the few cutting measures that doesn’t encourage job loss, layoffs, outsourcing, and cancellation of services often do. In addition to preserving jobs and creating new ones, efficiency measures also benefit the environment by reducing carbon pollution, which should make you feel confident about harnessing its ability to reduce your company’s annual energy costs by 50% or more, depending on your implementation measures.
The Cost Cutting Effect of an Energy Efficient Lighting Retrofit
Determining how best to cut your company’s energy costs begins with hiring an energy consultant to perform an audit of your building’s power use, a process that often reveals interior and exterior lighting as an area with room for improvement. Unlike appliances and other types of equipment, lighting equipment usually lasts for decades. In fact, what forces many lighting technologies to the junkyard is the cancellation of their parts, not the decision to replace them. As a result, millions of companies have inefficient lighting, which, without knowing how much they could save with efficient lighting, they often decide to keep in the name of cost savings.
To get an idea of how inefficient lighting could cost your company, consider that interior lighting alone accounts for roughly 60% of a commercial building’s annual electrical usage, and that, according to a study performed by the Center for Building Diagnostics at Carnegie Mellon, the improved light levels that come with efficient lighting retrofits can raise workplace productivity by 3-13.2%, a percentage whose importance is underlined by the Rocky Mountain Institute, which points out that even a 1% increase in productivity can result in more annual savings than a company spends on power use. Far from offering a few thousand dollars a year in savings, performing an energy efficient houston landscape lighting retrofit can dramatically impact a company’s annual profits.
The Efficiency Measures that Produce the Big Savings
Making a building’s lights more efficient usually involves replacing old fluorescent ballasts with newer ballasts and replacing incandescent lamps with compact fluorescent lamps and/or high intensity discharge lamps. But it also involves measures that manage the use of lights, such as improvement of lighting controls, de-lamping, and improved light settings.
- Improvement of Lighting Controls
To improve a building’s lighting controls, an energy consultant may recommend the rewiring of light switches so that single switches no longer control multiple lights, and the installment of automatic lighting controls that regulate light levels based on physical movement, natural light, time of day, work schedules, etc.
When you de-lamp your building, you remove unnecessary lamps. Due to the improved light levels that come with most retrofits, de-lamping can result in the removal of everything from large exterior lamps to lamps within vending machines.
- Improved Light Settings
When you improve your light settings, you take measures that prevent the need for additional lamps, such as: adding lenses to fixtures to focus light on certain areas, adding reflectors to fixtures to spread light, and painting walls a lighter color.
