What Are the Best Practices for Reducing Light Pollution from Commercial Real Estate?

April 4, 2024

In the bustling world of commercial real estate, lighting plays a crucial role in ensuring safety, enhancing aesthetics, and improving functionality. However, improper and excessive outdoor lighting can lead to light pollution, a growing environmental concern that affects not just the night sky but also our health, wildlife, and energy resources. How can commercial property managers effectively reduce light pollution? This article explores best practices to decrease light pollution from commercial properties, detailing measures like efficient light fixture selection, smart lighting strategies, the use of LED lights, and more.

Utilizing Efficient Light Fixtures

While illuminating commercial properties is essential, doing so in an environmentally friendly manner necessitates careful selection of light fixtures. Specific lighting fixtures are designed to minimize glare and light spillage, two key contributors to light pollution.

Selecting full-cutoff fixtures is one approach. These fixtures are designed to direct light downwards, which reduces the amount of light that escapes upward into the sky. Full-cutoff fixtures efficiently use light, ensuring that the illuminated areas are limited to those that require lighting. This design reduces light pollution while also saving energy, as less light is wasted.

Another efficient fixture is the shielded fixture. These fixtures have solid barriers that prevent light from being emitted above the horizon line. The shielded design decreases the amount of scattered light, reducing the glow that contributes to skyglow, a form of light pollution that washes out the night sky.

Switching to LED Lights

LED (Light Emitting Diode) lights offer a solution to light pollution concerns. LEDs are energy-efficient, long-lasting, and provide better control over the direction and color of light, making them an excellent choice for outdoor lighting in commercial real estate.

LED lights offer significant potential to reduce energy consumption. They use less energy than traditional bulbs to produce the same amount of light, leading to lower energy costs and lower carbon emissions. This improved energy efficiency does not compromise the quality of light, as LEDs can provide bright and clear light, enhancing public safety.

Moreover, LED lights are available in a range of color temperatures, allowing for the creation of warmer, less intrusive outdoor lighting environments. Cooler, bluer lights contribute more to light pollution as they scatter more and are more disruptive to wildlife. Opting for warmer, amber-colored LEDs can help to reduce this impact.

Implementing Smart Lighting Strategies

Smart lighting strategies can make a significant difference in reducing light pollution. Rather than leaving lights on all night, installing timers or sensors can ensure that lights are only on when necessary.

Motion sensors are particularly useful in less-trafficked areas of commercial properties. These sensors activate lights only when movement is detected, saving energy and reducing unnecessary light pollution.

Timers can also be used to control lighting based on the time of day or night. For example, lights could be programmed to switch off during the darkest hours of the night when fewer people are active.

Creating Dark Sky-Friendly Environments

Many commercial property managers are adopting ‘Dark Sky’ practices that aim to minimize light pollution while still providing adequate safety and security. The International Dark-Sky Association has established guidelines for outdoor lighting that promote the use of minimal light, only where and when it’s needed.

Dark Sky-friendly environments encompass not only the selection of appropriate fixtures and light sources but also strategic positioning of lights. Lights should be placed such that they illuminate the ground, not the sky.

Furthermore, unnecessary lights should be eliminated. If an area doesn’t require illumination for safety or functional reasons, consider leaving it dark. This practice not only reduces light pollution but also highlights the areas that are lit, improving visibility and safety.

Reducing Glare for Improved Safety

Glare, the excessive contrast between bright and dark areas, can obstruct vision and pose safety risks. Commercial properties often use high-intensity lights that can create glare, contributing to light pollution and reducing visibility.

Anti-glare lighting designs can help to tackle this issue. These designs diffuse light across a wider area, reducing the intensity of the light source and minimizing glare. Utilizing lower intensity lights where appropriate, particularly in areas where high-intensity light isn’t required for safety or security, can also help to reduce glare.

Implementing these practices in commercial real estate properties is not only environmentally responsible; it also contributes to the creation of safe, enjoyable, and aesthetically pleasing environments. Reducing light pollution is a significant step toward sustainable commercial real estate management, benefitting not just the night sky, but also our communities, the environment, and future generations.

Encouraging Community Initiatives and Public Awareness

Aside from implementing best lighting practices in commercial properties, another effective way to reduce light pollution is by promoting community initiatives and public awareness. The issue of light pollution often goes unnoticed due to lack of awareness. Hence, it is crucial to educate the public, including tenants, property managers, and local communities about its adverse effects and the ways to mitigate it.

Various non-profit organizations, such as the International Dark-Sky Association, offer resources and tools to educate the public about outdoor light pollution and its impact on human health, wildlife, and energy consumption. Leveraging these resources to enlighten the public can lead to collective action in reducing light pollution.

Local ordinances and building codes can also be reviewed and updated to incorporate dark sky principles. These principles promote the use of lighting fixtures that minimize light trespass and shield the night sky from artificial light. Regulations can be established to ensure outdoor lights are only used for their intended purpose and are switched off when not needed.

Businesses can also participate in community initiatives like Earth Hour, where lights are turned off for an hour to raise awareness about energy consumption and light pollution. Such initiatives not only contribute to reducing light pollution but also foster a sense of community responsibility towards environmental conservation.

Conclusion: Taking Active Steps Towards Sustainable Lighting Practices

In conclusion, combatting light pollution in commercial real estate involves a multi-faceted approach. It requires the careful selection of light fixtures, the strategic use of LED lights, the adoption of smart lighting strategies, and the creation of dark sky-friendly environments.

While technology and innovative lighting practices can significantly reduce light pollution, they are most effective when coupled with public awareness and community initiatives. Commercial real estate managers have a pivotal role to play in leading these efforts. By implementing sustainable lighting practices in their properties, they can contribute to creating a well-lit environment that respects the night sky and reduces light trespass.

In the face of growing environmental concerns, it is incumbent upon us to take active steps towards reducing light pollution. Not only does this contribute to the preservation of the night sky, but it also benefits our communities, our health, and our planet. A well-lit future is possible if we choose to shine responsibly.
