Evaluation methods and testing requirements for LED and solid-state lighting products are rapidly changing as new standards, metrics, and labeling programs become available to the lighting industry.

As a result, the Lighting Research Center (LRC) has developed a new professional lighting seminar, the Photometry Institute, to be held April 11-12, 2012.

In this two-day, interactive course, participants will come away with the knowledge and skills needed to establish and conduct photometric testing and evaluation of a wide range of lighting products and systems.

The National Electrical Manufacturers Association (NEMA) has published ANSI ANSLG C78.21—Incandescent lamps: PAR and R Shapes and ANSI ANSLG C78.40—Electric Lamps: Specifications for Mercury Lamps.

Providing physical and electrical characteristics of incandescent lamps, ANSI/ANSLG C78.21-2011 describes PAR and R bulb shapes. The standard covers lamps with clear, frosted and lens end bulbs, clear and prescription lenses, and with various reflector coatings. Lamps described in this standard may contain either of two basic types of light sources: an incandescent filament or a tungsten halogen inner bulb. Sunlamps and heat lamps of the R type are included. However, lamps with discharge arc tubes are not included.

ANSI ANSLG C78.40-2011 sets forth the physical and electrical requirements for single-ended metal halide lamps operated on 60 Hz ballasts to ensure interchangeability and safety. The data given also provides the basis for the electrical requirements for ballasts as well as the lamp-related requirements for luminaires. Luminous flux and lamp color are not part of this standard.

ANSI ANSLG C78.21 and ANSI ANSLG C78.40 are available for download at no charge at www.nema.org/stds/c78-21.cfm and www.nema.org/stds/c78-40.cfm.

According to a new report from Pike Research, worldwide revenue from zero energy buildings will grow rapidly over the next two decades, reaching almost $690 billion by 2020 and nearly $1.3 trillion by 2035. That represents a compound annual growth rate of 43%, with much of that growth occurring in the European Union.

Pike Research’s report, “Zero Energy Buildings”, provides data on the size and growth of the market for zero energy building markets, including HVAC systems, glazing systems, wall and roof construction, renewable energy systems, and construction soft costs, from 2011 through 2035. The study also includes a qualitative assessment of major drivers and trends for zero energy buildings in key markets, including both commercial and residential zero energy buildings. It also provides a discussion of the individual technology elements associated with zero energy building, as well as the design challenges that the AEC (architecture/engineering/construction) service providers will face in delivering zero energy buildings. An Executive Summary of the report is available for free download on the firm’s website.

Common household lamps now carry uniform labeling to facilitate educated decisions focusing on light output and energy costs, not watts, helping consumers transition to more efficient lamp types. That’s the topic of an article I contributed to the January 2012 issue of Electrical Contractor Magazine. Read it here.

The U.S. Green Building Council (USGBC)’s LEED Volume Program for Operations & Maintenance is available for existing green building projects.

The LEED Volume Program streamlines the certification process for high-volume property owners and managers of existing buildings and new construction projects. Utilizing a prototype-based approach, the program enables large-scale builders, owners, and managers to achieve consistency in green building improvements, allowing them to earn LEED certification faster and at a lower cost than would be possible with individual building reviews.

The Operations & Maintenance track was shaped by 11 commercial real estate firms, national retailers, hospitality providers, colleges and universities, local and state governments and federal agencies, including Cushman & Wakefield, Bentall Kennedy, City of San Jose, Kohl’s Department Stores, Stop & Shop, Bank of America, University of Florida, American University, University of California Santa Barbara, Wells Fargoand InterContinental Hotels Group.

More than 625 building projects have certified through the LEED Volume Program, including Starwood Hotels & Resorts, The PNC Financial Services Group, Best Buy, Marriott, Citigroup and Starbucks Coffee Company. USGBC launched the program for the design and construction of new building projects at its Greenbuild International Conference & Expo in November 2010.

DOE Releases GATEWAY Report on Walmart Parking Lot Lighting

The U.S. Department of Energy (DOE) has published the final report from a demonstration conducted at a Walmart Supercenter in Leavenworth, Kansas, to evaluate the use of solid-state lighting (SSL) technology in a commercial parking lot lighting application.

This GATEWAY demonstration report provides an overview of project results including lighting performance, economic performance, and potential energy savings.

In this project, LED luminaires were installed in a parking lot covering more than a half-million square feet. Since the demonstration was at a newly constructed store, no baseline system existed, so comparisons were made to hypothetical designs using 1000W pulse-start metal halide (PMH) lamps and 400W PMH lamps. Key findings include:

Compared to the 1000W PMH system, the LED system would achieve energy savings of 63 percent with a 68 percent reduction in the minimum illuminance values. In comparison to the 400W PMH system, the LED system would achieve 44 percent energy savings while providing virtually the same minimum illuminance values.

The LED system had 6.1- and 7.5-year paybacks, respectively, compared to the 1000W and 400W PMH systems at Leavenworth’s relatively low electricity rate of $0.056/kWh. These paybacks were reduced to four and five years, respectively, when using the national electricity rate of $0.1022/kWh.

This installation represents the first use of the LED Parking Lot Performance Specification, developed by DOE’s Commercial Building Energy Alliances, and demonstrates that the specification works in practice.
