Once a storage vessel for oil, Silo 468 has become a beacon in Helsinki's new district of light.
After some initial grappling with LED technology, the lighting industry has begun leveraging its distinct performance and potential.
Advancements in thermal management strategies for LED fixtures pave the way for design innovation.
The high-performance facility in Washington, D.C., by HOK uses a dynamic façade to draw in sunlight without the heat.
Discussion of the interaction between new materials and new lighting technologies.
Change can be hard. Witness the reluctance with which some building owners, and even consumers, are approaching the switch to certain lighting technologies, such as T8s and LEDs—even though these sources meet new energy mandates better than previous options.
Computer-aided design has elevated lighting design into a realm of automation and visualization that was unimaginable just a few decades ago.
Building management systems bring us one step closer to dummy-proofing your clients’ lives—if we can design and program them correctly.
Lighting controls have always been an essential component of a lighting system, as they enable basic functionality: turning lights on and off, and dimming.
Today, we are in the midst of an era of regulated efficiency. And as a major consumer of electric energy in commercial buildings, lighting is subject to a large host of design restrictions and control requirements. Various product standards are affecting the availability of lighting equipment...
Upcoming regulations are set to have a large-scale impact on reflector lamp availability as the least-efficient and lowest-cost options give way to higher-efficacy models.
Lighting designers commonly rely on two metrics to evaluate, compare, and predict the color performance of white light sources in applications where color is important: correlated color temperature (CCT) and color-rendering index (CRI).
Designing for LEDs and their specific attributes.
Japanese architects and designers integrate materials and light.
The DOE's CALiPER testing program helps the lighting industry navigate the latest SSL product offerings.
There is growing evidence that personal control over lighting is a key determinant of office-worker environmental satisfaction and productivity.1 For one, the U.S. Green Building Council's (USGBC) LEED rating system clearly recognizes that individual user control is a contributor to indoor...
It has long been common knowledge that no artificial light source can be properly assessed for its color performance simply by its color temperature alone. Depending on the spectral reflectance distribution (SRD) of the object or surface being illuminated, two lamps of the same color temperature...
Jim Benya discusses residential lighting controls
Until the mid-1970s, buildings usually were designed without any type of lighting control. In fact, many also were designed without heating systems, because of the enormous heat produced by 24-hour operation of indoor lighting systems. In hot climates, you can imagine how this added to the amount...
The real issue surrounding UL is whether its standards are current, necessary, cost effective, and fair. Most U.S. fixture makers (including those with offshore manufacturing) are resigned to meeting UL and many have set up in-house UL testing labs to do the work, keeping costs low. But for...
