Codes & Standards: Lighting
Our enlightening and spirited discussion of value engineering (VE), also known as value analysis, continues. Its ardent defenders have been its practitioners, while the most vocal detractors have been consulting design engineers. For example, Gregory Josephs, P.E., of Philadelphia, was involved with modifications to sedimentation tanks at a large sewage-treatment plant, and VE was mandated by...

Concern over cross-contamination between different cleanliness classes within a clean-room garment-changing area led an in-house engineering team at the Belgium facilities of Alcon Laboratories, a pharmaceutical company based in Ft. Worth, Texas, to carry out a design study simulating air movement, heat transfer and distribution of contaminants through the rooms.
The results are in. Commercial building owners in the United States could save between $2.7 and $3.6 billion dollars per year by simply cleaning fixtures on a regular basis, according to a federally-funded four-year building-lighting study conducted by the InterNational Association of Lighting Management Companies (NALMCO), Des Moines, Iowa.
Engineers and lighting designers can now access useful information on fluorescent and high-intensity-discharge lamp recycling at a new Web site—www.lamprecycle.org—sponsored by the National Electrical Manufacturers Association, Rosslyn, Va. The Web site includes information about federal and state regulatory lamp management requirements, state regulatory contacts, a list of compan...
Magnetic-drive pumps are specifically designed to handle difficult fluids such as corrosives, pollutants, ultrapure liquids and toxics. This seamless pump can handle flows up to 1,500 gpm at 2,900 rpm and 1,760 gpm at 3,500 rpm. (Model ICM by Goulds Pumps) Circle 1 Structured cabling system doubles the bandwidth of the proposed category-6 standard, tested to perform at up to 400 MHz.
Shipments of lighting fixtures in the U.S. are expected to rise over 5% annually through 2008 to over $14.4 billion, according to Lighting Fixtures , a new study from The Freedonia Group, an industrial market search firm. This pace represents a significant acceleration from the 1998-2003 period as improving economic conditions boost demand in both construction and manufactured goods markets. Advances in lighting fixture demand will also be supported by an ongoing focus on energy efficiency, which will lead to residential remodeling activities and nonresidential retrofit projects aimed at increasing the energy efficiency of existing lighting systems.
For more than three decades, the Natural Resources Defense Council (NRDC) has been a leading voice for environmental advocacy in the US. When the group decided to open a regional office in Santa Monica, California, they knew it had to be environmentally friendly. The building, named for Robert Redford, actor and long-time environmentalist, would combine cutting-edge technologies and materials with energy-efficient architecture to create a showcase for green-building design and promote environmental activism. The building, extensively remodeled by the NRDC and opened in November 2003, pushes the envelope for environmental design and construction techniques.
Penn State’s Department of Architectural Engineering has installed the first Internet-controllable lighting laboratory in the world, based on the digital addressable lighting interface (DALI). The DALI interface allows users from any PC and any location to control any lamp in this laboratory with a web browser; observe the effects with a web camera; and remotely monitor energy use and time-of-day use. Most recently, the control system was on display at Lightfair 2004 in Las Vegas.
As one of the founding teams in the league that would become the NFL, the Chicago Bears are steeped in traditions that run deeper than most. The roster of retired Bears jerseys on display in the lobby of the team headquarters is awe-inspiring, the names timeless: Blanda, Butkus, Ditka, Payton, Sayers. The faithful converge on Soldier Field every home Sunday, win or lose, to shiver in the open air as the wind howls off Lake Michigan. Even the stadium itself, until recently a crumbling Greek temple with peeling plaster and questionable plumbing, has been part of the team’s mystique for more than 30 years. In such a franchise, change does not come easy.
