In addition to his professional accomplishments in the Miami area, William Pino holds membership in the Illuminating Engineering Society (IES) of North America.

In a recent study of the impact of the 2016 IES and American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.1 on the cost of energy compared to previous standards, Pacific Northwest National Laboratories (PNNL) found that Standard 90.1 saves just north of 34 percent compared to IES’s previous standard published in 2004. PNNL conducted this research as part of the U.S. Department of Energy’s (DOE) Building Energy Codes Program.

Commenting on the study, ASHRAE president Tim Wentz noted the four decades of cooperation between his organization and IES to constantly update Standard 90.1 in accordance with modern developments in energy savings and production. He also predicted that the two groups would continue to push forward to find the most energy savings possible, even as the work becomes more difficult in the face of inherently efficient new technologies.

AMA Warns About LED Street Lighting

William Pino serves as president and CEO of Main Street Engineering, a Miami consulting firm of which he is also the founder. William Pino’s company has been involved in jmajor outdoor lighting projects, including a lighting upgrade at The City of Coral Springs, Florida.

LED lighting is now often used in municipal outdoor lighting applications but it is not always pleasant to the eyes, and lowering the “color temperature” can be a significant improvement. In June of 2016, the American Medical Association (AMA) announced an official policy statement concerning street lighting – that lights need to be both “cooler” and dimmer. Since municipalities are replacing traditional bulbs with LEDs, the AMA recommends that the color temperature, or measure of spectral light, not exceed 3000K.

Several US cities adopted lighting systems in the 4000-5000K range, with a higher quantity of blue in the light spectrum. Residents of Davis, California, for example, found the high-temperature lights so disagreeable, they demanded their replacement. High-temperature illumination causes two problems: Glare and discomfort. If the blue light concentration is so high that glare is excessive, this can result in constriction of the pupils or even damage to the retina.

The AMA also cited the ill effects of high-temperature light on human circadian rhythms. White LED lights are estimated to suppress melatonin (the chemical responsible for sleep) five times more efficiently than the high-pressure sodium lamps they replace, so people subjected to this light are increasingly suffering from sleep disorders.

Respecting Wildlife with Responsible Lighting Design

William Pino, a Miami-based entrepreneur and businessman, has over 35 years of experience applying his electrical engineering training to municipal outdoor lighting projects. The effect of light pollution on sea turtles is a concern in Miami and other coastal areas, and William Pino has supported environmentally friendly, energy-efficient designs that consider animals’ sensitivity to artificial light.

Scientists have determined that the brightness and glare of artificial lighting can be disorienting to sea turtle hatchlings that are trying to find their way back into the ocean. Instinct directs small sea turtles toward the brightest light on the horizon, historically moonlight reflecting off the ocean. As inland lighting continues to increase, however, the hatchlings can easily become confused and wander in the wrong direction.

Many counties in Florida have passed lighting ordinances to regulate artificial lighting on beaches. These ordinances prohibit the use of bright, white lights such as metal halide, fluorescent, mercury vapor, and incandescent bulbs. Instead, fixtures must utilize low-pressure sodium bulbs, true red neon, or LED bulbs using red, orange, or amber light.

Experts suggest that beachfront property owners do their part by taking the following precautions:

– Turn off any unnecessary lights, and avoid outdoor decorative lighting.

– Face lights away from the beach, and use shields or flashing to keep light off the beach.

– Use directional fixtures rather than lights that provide general ambient lighting.

– Use bulbs with the lowest wattage possible.
