When you look for ways to enhance your profit margin, energy management is a logical place to look for changes. Doing an energy audit or switching to energy-efficient lighting, two key steps in an energy management program, can have a significant impact on the bottom line. Yes, as the operator of a large facility or multiple large facilities, you will need to make an investment--perhaps substantial--to get the ball rolling on energy management, but the data compiled by the U.S. Department of Energy's Energy Star clearly indicates that the savings will be real, and that you will begin to realize them in fairly short order. Energy Star notes, for example, that the average commercial building wastes 30 percent of the energy it consumes.
Understanding energy management strategies can help your business benefit fiscally, but it has other advantages as well. If you’ve not explored this area before, take time to review key property and behavioral changes that can boost your business' profits, improve productivity and increase safety.
Switching to LEDs
One of the biggest ways to reap savings comes from small sources—your lighting. The newest generation of bulbs, light-emitting diodes or LED lighting, offers more bang for your buck than traditional lighting options such as standard filament (incandescent), halogen and fluorescent strips. LED bulbs can last far longer than other lighting choices, with a range of 20,000 to 70,000 usage hours, while the average lifespan of incandescent bulbs is a diminutive 1,200 hours. LEDs also outdistance another energy-saving choice, the compact florescent lights (CFLs), by four to five times the lifespan.
Fewer replacements means lower direct and indirect costs, as well as reduced hazard potential. When you switch to LED lighting, you’ll spend less money replacing bulbs, and you also won’t be bogged down with frequent, time-consuming production delays while new bulbs are installed. In many cases, the replacement of ceiling bulbs requires an aerial lift or extension ladder, which can contribute to numerous safety hazards. Limiting the number of times this is conducted by installing longer lasting LED lighting is certainly an indirect but vital benefit to productivity and worker safety. Plus, since LED tube lights do not require a ballast the way fluorescent tube lighting does, you’ll need little pricey maintenance of the fixtures.
But the biggest bonus is in the energy reduction. Not only do LEDs last longer, they use just a fraction of energy (up to 80% less) of conventional lighting and throw off far less heat, which can reduce your need for cooling and air conditioning. Remember that halogen and incandescent bulbs produce light as a by-product of heat and release up to 90 percent of their energy as heat. LED bulbs, by contrast, provide light as their foremost function and release little heat. Switching to LED lighting, means your organization can start seeing an almost immediate return on investment as monthly electric bills plummet.
LED lighting has additional benefits that help it outperform other choices. For property areas that necessitate prompt lighting, LED provides the security of immediate bright lighting, unlike CFLs, which require time to reach full brightness. If full brightness isn’t required, a dimmer switch can be used on LED lighting, which is not an option for some lighting products.
To add to their many cost saving benefits, LEDs are more durable to shock, vibrations and temperature extremes than traditional lighting. The bulbs also do not contain harmful mercury, which means LEDs are environmentally friendly. They spread light uniformly, come in a range of hues, from soft amber to bright white, and can be tailored to the location and user preference. These factors can increase worker productivity and property security. The low heat emitted by LEDs also makes them a safer option than traditional lighting.
You won’t drop a bundle making the upgrade. If you’ve priced LED lighting in the past, you may be pleasantly surprised to find the price has significantly dropped in recent years. Bulbs that once cost a hundred dollars each, have dropped to a fraction of that, with most standard LED bulbs in the range of three to eight dollars. The lower price point means business owners can now retrofit the entire property with LED at a very nominal cost. (The U.S. Department of Energy has a run-down on options, complete with cost comparisons, here.)
To make additional and meaningful cost reductions, look at your workforce. Profit improvements can be made by modifying behavior to be more energy efficient. Although behavioral changes aren’t as easy as replacing light bulbs, new habits can be learned over time, especially when they are embraced as a whole organization.
Among ways to save costs and conserve energy:
- Perform routine maintenance on equipment, especially on HVAC systems
- Install or use fans to assist HVAC systems
- Keep the thermostat low on weekends and after hours
- Institute practices to keep vents clear and unobstructed
- Inform employees which equipment can be shut off when not in use
- Use laptops, as opposed to energy-hungry desktop computers
- Make it a practice to turn lights off when areas are not in use, or install motion detectors
Whenever possible, select energy-efficient windows, appliances and equipment, such as those labeled as Energy Star® certified. These products are designated to save significant energy and meet stringent industry requirements. For example, computer monitors that are certified Energy Star are 25 percent more energy efficient than standard options. If you have an entire department using outdated monitors and computers that consume large amounts of energy, replacing these with efficient models might be an investment that pays for itself in a relatively short time.
