Decoding California’s Title 24, Part 6

William Attardi on August 26, 2025

Commercial building energy codes regulate the design of nonresidential buildings to minimize energy consumption. While the majority of U.S. states adopt model codes and standards, the State of California developed its own code: Title 24, Part 6 of the state’s Building Standards Code. The latest version was released in 2025 and will take effect January 1, 2026. Title 24, Part 6 covers residential, nonresidential, high-rise residential, and hotel/motel buildings. Title 24, Part 6 contains robust, detailed lighting and control requirements. It requires a broad range of controls to ensure general lighting is turned Off or reduced when not needed.  .  For lighting, a number of changes have been made, mostly adjustments and clarifications.

Lighting Revolution in Two Graphs: LED Distribution In Residential And Commercial Applications by Craig DiLouie

William Attardi on January 15, 2025

As the LED revolution achieves increasing adoption, a recent report by the Department of Energy illuminates the growth. Published in April 2024, the “2020 U.S. Lighting Market Characterization” https://tinyurl.com/3fczwe9s estimates technology distribution among the U.S. installed base of units (lamps/luminaires), along with energy consumption. Residential sector: Let’s start with the residential lighting sector, where an estimated 6.5 billion units are installed, accounting for 80% of lighting installations. LED was the most popular light source in 2020 with 3.1 billion units installed or 48% of the total, nearly 50% less energy than in 2015.  Commercial buildings: In the commercial building sector, with its estimated 1.6 billion installed units, we see a similarly striking snapshot of LED earning virtual parity with other light sources. In 2020, LED reached an overall share of 48% of the installed base and a rough parity with fluorescent, nearly 30% less energy than 2015 and 57% less than 2001. Again, LED adoption is today the majority light source in commercial buildings.  Lighting Revolution in Two Graphs: LED distribution in residential and commercial applications – Electrical Contractor Magazine

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.
