The Facts About Lighting
Simply put, Energy Efficiency is using technologies that require less energy to perform the same function. For example, an LED light bulb provides the same, if not superior, lighting than an incandescent light bulb.
In a typical commercial building (including schools), heating, cooling, and lighting account for nearly 70% of energy use according to national data. When it comes to become energy efficient, a lighting retrofit is the first project that decision makers invest on because it is the most cost-effective. On average, lighting retrofits can yield a 45% ROI in about two years. Local rebates and incentives can bring the ROI down even more.
It is also recommended to embark on a energy efficient lighting project before sizing a solar array for energy generation (Photovoltaic system). This will reduce the facility’s load and therefore the size of the array needed, resulting in less costs related to a solar project.
Light-emitting diode (LED) technologies use less energy and operate at lower temperatures, which helps reduce cooling costs. They also last much longer and require less maintenance. Best of all, these advanced technologies offer all these benefits while providing equal- or better-quality light.
Additional benefits and technological advantages of LEDs:
LEDs turn on at full brightness almost instantly with no strike delay, even when cold, making LEDs the superior option for cold locations, such as walk-in refrigerators, cold storage facilities and outdoor areas like parking lots.
LEDs last up to three times longer than traditional incandescent and fluorescent lamps.
LED efficacy continues to improve, with some products delivering up to 170 lumens of light output per watt (LPW) resulting in significant energy savings.
LEDs are resistant to breakage and heavy vibrations because they do not have filaments or glass bulbs.
LEDs are mercury-free and have fewer environmental toxins that other lighting technologies, reducing disposal costs.
Quality LEDs can be dimmed and when compatible lighting controls are added, it’s possible to eliminate overlighting and greatly enhance savings.
LEDs reduce damage to organic materials and historic artifacts caused by ultra-violet (UV) radiation. They emit much less radiation than traditional incandescent or halogen light sources, making them great choice for museums and homes.
