Can Better Lighting Unlock a Healthier, Higher-Performing Office? by Fabio Zaniboni

Outdated lighting can hurt employee performance—but replacing it with human-centric smart lighting systems can restore productivity while operating efficiently. Here’s how.

  • Traditional office lighting often causes eye strain and fatigue, negatively impacting employee performance and well-being.
  • Human-centric smart lighting systems mimic natural daylight, supporting circadian rhythms and improving sleep quality and alertness.
  • Data-enabled lighting provides real-time insights into space utilization, enabling more efficient energy use and workspace optimization.
  • Personalized lighting controls empower employees, enhancing their comfort and perceived productivity in hybrid work environments.
  • Adopting wellness-focused lighting aligns with standards like WELL and LEED, giving organizations a competitive edge in attracting top talent.

DesignLights Consortium Seeks Self-Nominations for Industry Advisory Committee Members

The DesignLights Consortium today announced it is accepting self-nominations through October 3 from lighting industry representatives interested in serving on the DLC Industry Advisory Committee (IAC). An advisory body that meets quarterly, the IAC supports the mission and strategic direction of the DLC to promote the adoption of quality lighting and controls technology through education, collaborations, and expertise. Its activities include consideration of DLC business updates, programs to enhance lighting quality, utility lighting program participation, and ongoing opportunities, challenges, and potential risks related to advancement of energy-saving lighting technologies. The DLC is seeking new members for a two-year term that begins the third quarter of 2025 from the following organization types:

    • Small lighting manufacturers (companies with fewer than 250 employees, with product(s) listed on the DLC’s Solid-State Lighting or Horticultural Qualified Products Lists)
    • Lighting specifiers, including designers, energy service companies, consulting engineers and integrators
    • Lighting distributors.

The DLC is gathering self-nominations through an online form, must be submitted by October 3.

The Role of Energy Audits in Enhancing Facility Performance by Ellie Gabel

According to the U.S. Department of Energy (DOE), approximately 30% of the money used to power buildings — around $400 billion annually — is wasted yearly. A professional-grade energy audit can help facility managers reduce electricity expenses without compromising comfort or safety. During a commercial energy audit, an auditor assesses how, where and why a facility consumes power. They aim to address inefficiencies and identify areas of opportunity, enabling a substantial energy consumption reduction. Whatever the audit’s results, management will receive a baseline on the property’s energy consumption, waste and reuse effectiveness rating. They can use this data to identify pain points, explore areas of opportunity, or prioritize equipment upgrades. Nearly 40% of a building’s energy usage can be attributed to lighting. Replacing outdated lighting fixtures with more energy efficient options can drastically reduce those costs. The Role Of Energy Audits In Enhancing Facility Performance

The Statue of Liberty was made with copper but due to oxidation, it turned green.

When the “Lady in the Harbor” first arrived in New York in 1886, she didn’t look like the mint-green icon we know today. In fact, for the first twenty years of her life, she stood as a towering, metallic beacon of reddish-gold. Designed by French sculptor Frédéric Auguste Bartholdi and engineered by Alexandre Gustave Eiffel, the statue was a gift from France to America. To build her, Bartholdi chose copper for three practical reasons:

  • Malleability:It could be hammered into elaborate, thin sheets.
  • Weight:Copper is lighter than stone or bronze, making it easier to ship 350 individual pieces across the Atlantic.
  • Durability:It was strong enough to survive a 27-day ocean voyage and the harsh winds of the harbor.

When she was unveiled on October 28, 1886, her skin—made of 300 copper sheets roughly the thickness of two pennies—shone with a bright, metallic brown luster. The transformation from “penny-colored” to “patina-green” wasn’t planned. Bartholdi actually expected the statue to age into a deeper, darker red. However, the unique environment of New York Harbor—a mix of salt air, moisture, and industrial pollution—triggered a process called oxidation.

The Timeline of Change:

  1. 1886–1900:The bright copper dulled into a dark, muddy brown.
  2. 1903:The first hints of a light green crust, or “patina,” began to appear.
  3. 1906:The color change was so controversial that Congress nearly stepped in. They appropriated $62,000 to paint the statue back to its original color, but the public protested, calling the idea “sacrilege.”
  4. 1910–1920:The statue was a patchy mix of brown and green until 1920, when the oxidation was complete, leaving her entirely teal.

While we now view the green color as iconic, it actually serves a vital structural purpose. The layer of verdigris (the green patina) acts as a protective shield. It seals the copper underneath, preventing the metal from further corrosion and weathering.  By the time the color fully changed, a new generation of immigrants had arrived in America seeing a green statue.
