Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy The emergence of high-frequency electronic ballasts for use with fluorescent lighting did away with most general-illumination flicker concerns back in the 1990s. That is, until the advent of LEDs, which have put [...]

The Lighting Controls Association recently published a whitepaper I wrote about the 2012 Commercial Buildings Energy Consumption Survey, published in stages this year by the Department of Energy. The 2012 CBECS provides an estimated profile of the U.S. commercial building stock based on an interviewed sampling. Information includes number of buildings, floorspace, age, building type, [...]

Riding a stretch of increasing levels of demand for 13 out of the last 15 months, the Architecture Billings Index (ABI) dropped in April for the second month this year. As a leading economic indicator of construction activity, the ABI reflects the approximate 9- to 12-month lead time between architecture billings and construction spending. The [...]

After its first negative score in ten months, the Architecture Billings Index (ABI) showed a nominal increase in design activity in February, and has been positive 10 out of the past 12 months. As a leading economic indicator of construction activity, the ABI reflects the approximate 9- to 12-month lead time between architecture billings and [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy As we approach a holiday that’s all about gratitude, I’d like to take this opportunity to express my personal gratitude to Shuji Nakamura, Isamu Akasaki, and Hiroshi Amano. In awarding the three [...]

Maury Wright, editor of LEDs Magazine, had an interesting editorial that started the November 2014 issue. Focusing on color-tunable white light and new form factors, he says LEDs are beginning to realize vast transformative potential, though there’s still work to be done. Of particular interest is what we know about light’s impact on human health, [...]

With all geographic regions and building project sectors showing positive conditions, there continues to be a heightened level of demand for design services signaled in the latest Architecture Billings Index (ABI). As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lead time between architecture billings and construction [...]

Below is an article I contributed to the June issue of TED Magazine, reprinted with permission: The American Institute of Architects’ Consensus Construction Forecast predicted nonresidential construction spending to increase 5.8 percent in 2014 and 8 percent in 2015, a rebound led by the commercial sector. Combined with a healthy market for lighting upgrades, this [...]
