The CSIL Centre for industrial Studies in Milano, Italy recently published a new report, E-Commerce in the Lighting Fixtures Sector. The report states that e-commerce accounts for 4% of the $75 billion global luminaire market, including both B2B and B2C. North America is the largest e-commerce market for luminaires; its incidence on the world market [...]

The U.S. Department of Energy (DOE) has released a report analyzing markets where light-emitting diodes (LEDs) compete with traditional lighting sources (e.g., incandescent and fluorescent). The report, Adoption of Light-Emitting Diodes in Common Lighting Applications, provides estimates of current energy savings, plus potential savings if these markets switched to LEDs overnight. Nine markets were analyzed: [...]

The Department of Energy’s Commercial Buildings Energy Consumption Survey is one of the most valuable ongoing research resources for the lighting industry, profiling number of buildings, floorspace square footage and other information by building market type. Unfortunately, the 2007 CBECS was scrapped due to poor research method, and DOE is still working on the next [...]

This recorded webinar presented by Dr. Craig Bernecker of Parsons, which you can watch below, provides a sampling of studies conducted that illustrate both psychological and physiological responses to lighted environments.

Editor’s note: This is the executive summary of the Commercial Lighting Market Attitudes Study, which I produced in 2004 based on surveys of participants across the commercial lighting product sales channel. I’ve been receiving some renewed interest in the study, which people have found valuable, so I decided to offer the report’s conclusions here. What [...]

I recently authored an article for the Lighting Controls Association about a recent Energy Center of Wisconsin study demonstrating that proper commissioning of daylight harvesting lighting controls can lead to higher energy savings. But an even bigger lesson, I believe, can be found in commissioning all automatic lighting control systems. Read it here.

Precision-Paragon [P2] recently published the results of its Energy-Efficient Lighting Industry survey, distributed to more than 4,000 energy efficiency professionals. The survey results show that 77% of survey respondents expect their energy-efficient lighting revenue to grow in 2013. The survey also suggests that automated lighting controls, such as occupancy sensors, are being specified in nearly [...]

Roundabouts, also known as traffic circles, are increasing in number across the U.S. These intersections generally increase traffic flow while reducing the severity of automobile accidents. However, as relatively new traffic features, modern roundabouts are sometimes described as confusing for drivers. One difference between roundabouts and conventional cross-type intersections is the location of pedestrian crosswalks. [...]
