    Around the Circuit
    Frozen Food Aisles
    May Get a Facelift

    The Lighting Research Center (LRC), located at the Rensselaer Polytechnic Institute in Troy, N.Y., recently embarked on a research project to evaluate the feasibility of using light-emitting diode (LED) technology in commercial display freezers. The study, funded by the New York State Energy Research and Development Authority, will compare performance, energy savings, shopper preferences, and product sales of a prototype LED lighting system and its fluorescent counterpart found in most supermarket freezers. Results will be published in spring 2005. In a previous study, the LRC developed a prototype refrigerator lighting system using LEDs with the goal of reducing energy usage and producing better illumination for the merchandise. The results showed that the LED lighting system produced more uniform illumination on the displayed products and was strongly preferred by more people than traditional fluorescent lighting in this application.

    Simple. Reliable. Accurate.
    AEMC Instruments' clamp-on ground resistance testers measure ground rod and grid resistance in any environment without the use of auxiliary ground rods. Both testers measure ground resistance from 0.01 ohm to 1200 ohms without disconnecting the rod under test. The Models 3711 and 3731 also measure ground leakage and phase current from 1mA to 30Arms. The large jaw (1.25") accommodates ground conductors up to 1000MCM. The Model 3731 includes both an alarm function and a memory function, which will store up to 99 field measurements.

    New Green Building Rating System Unveiled, San Francisco Adopts Green Building Ordinance
    Following the success of its Leadership in Energy and Environmental Design (LEED) for New Construction (LEED-NC), the U.S. Green Building Council (USGBC), Washington, D.C., has announced the release of the LEED for Existing Building (LEED-EB) Green Building Rating System. Designed to meet market demand for an existing building rating system, LEED-EB will help building owners and managers maintain high performance in their facilities. For more information, visit the organization's web site.

    In a related story, San Francisco recently joined nine other cities that have already adopted green building ordinances requiring LEEDs. The new mandate requires that all new projects, renovations, and building additions, including city-owned and leased facilities, achieve an LEED Silver certification from USGBC. "This Green Building Ordinance will translate into millions in savings on future operational costs for new city buildings," says Jared Blumenfeld, director of the San Francisco Department of the Environment.

    Daylighting Controls May Make Inroads into National Energy Code Inclusion
    Although several jurisdictions across the country require daylighting controls in new nonresidential construction, these devices do not yet occupy a prominent position in most energy codes. However, that may be changing. According to the October Energy Statement newsletter from the Watt Stopper, Santa Clara, Calif., experts agree that the major reference standards will most likely mandate these controls within the next few years. Currently, individual states handle them differently. Both California and Wisconsin require the use of either automatic or manual daylight-responsive controls in daylit areas greater than 250 square feet. In daylit areas, building owners must install at least one controller that independently controls at least 50% of the luminaires in that space. Wisconsin adds the requirement of separate daylighting controls for vertically daylit areas (skylights) and horizontally daylight areas (windows). In California, Title 24 will add the requirement for automatic daylighting controls in large high bay spaces in 2005. The Oregon Uniform Building Code requires daylighting controls in classrooms and atriums. The Seattle building code takes a "zone" approach similar to that of California and Wisconsin, requiring daylighting control in any space that is defined as a "daylight zone."

    Value of Construction
    Remains at Record Level

    According to a recent report from the Associated General Contractors of America, the value of construction in September tied the record set a month earlier. In August, the industry reached a seasonally adjusted annual rate of $1.014 trillion, according to the U.S. Census Bureau. For the first nine months of 2004, value put in place rose 9% from January to September 2003, and gains were widespread. In private residential construction, single-family jumped 22%, multi-family gained 10%, and improvements were flat. Four private nonresidential components reported substantial gains: lodging (+12%), amusement and recreation (+11%), health care (+10%), and office (+8%). The largest subcomponent, commercial (retail and wholesale), rose 5%. Four private nonresidential components fell: power, educational, and religious were down 5%, and manufacturing declined 2%.

A mandatory site tour will be conducted on or about Dec. 15, and bids are due Jan. 5, 2005. Interested parties must submit an expression of interest letter to be received no later than Dec. 1, addressing the pre-qualification criteria outlined in the request for proposal.

    Ground-Fault Relay Protection Schemes
    Following the bare minimum safety requirements for ground fault relays at switchgear and switchboards may save money, but as David Murray of IPC Resistors points out, it can also cause problems for downstream devices. Learn what not to do. For the full story, click here.

    Eye on Safety
    Did you know that one in five workplace fatalities is a construction worker, approximately 350 electrical-related fatalities occur each year, and falls from elevation account for one-third of all deaths in construction? These are just a few fast facts available in OSHA's Construction Facts e-Tools resource, an interactive, Web-based training tool designed to help users identify and control hazards that commonly cause the most serious injuries in the construction industry. To help establish safety guidelines and best practices for electrical work, visit this online resource for more information.
