In The News AMCA revises Laboratory Accreditation Program and approves new air curtain manual The Air Movement and Control Assn. International Inc. (AMCA) revised its publication 111-99, Laboratory Accreditation Program, which now recognizes ISO 13347:2004 Fans—Determination of fan sound power levels under standardized laboratory conditions. The revised testing methods include four parts: Part 1: General overview, Part 2: Reverberant room method, Part 3: Enveloping surface methods, and Part 4: Sound intensity method. By recognizing the standards, products tested in accordance with the standards will have their performance certified using the AMCA Certified Ratings Program. Along with the addition of expanded tests recognized by AMCA, the accreditation program now requires periodic visits to the accredited lab to ensure proper maintenance. An AMCA Accredited Laboratory is a laboratory that has been accredited in accordance with AMCA Publication 111, Laboratory Accreditation Program. In addition to the changes made to the testing methods, AMCA approved AMCA 222-08, a new application manual for air curtains. The application covers air curtain theory, components, construction, testing, and certification of ratings, applications, benefits, selection, purchase, installation, service, and maintenance. The manual also provides an overview of the basic design, benefits, and applications for air curtain units (ACU). The manual describes how, when properly installed, ACUs maintain environmental integrity between two distinct areas, which provides clear, unobstructed egress and ingress. The ACUs save energy by reducing the infiltration of warm or cold air through an opening. By reducing the infiltration of outdoor air, the ACUs allow the primary HVAC equipment to work less. The revised publication 111-99 is available for download at http://cart.amca.org/publications, and the AMCA 222-08 Application Manual for Air Curtains is available at www.amca.org. NEWS AT A GLANCE • San Jose, Calif.-based LonMark Inter national—a non-profit standards development and industry trade association—has announced that members of the Joint Technical Committee (JTC 1) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have formally approved LonWorks control networking technology as ISO/IEC 14908, Parts 1, 2, 3, and 4. First introduced 18 years ago, the control networking technology has been used worldwide. The ratification stands to enhance the adoption and usage in the controls market, specifically in vertical construction. The four parts of the standard set comprise the core protocol; the twisted-pair, free-topologywiring transfer medium; the powerline transfer medium, and the use of the IP as a tunneling transfer medium. IALD partners with DOE The International Assn. of Lighting Designers (IALD) and the U.S. Dept. of Energy signed a Memorandum of Understanding (MOU) to work cooperatively toward improving the efficient use of energy by lighting equipment and systems. The MOU emphasizes the importance of minimizing the impact of energy use on the environment in support of DOE Solid State Lighting (SSL) programs on lighting quality. The MOU highlights five key areas in which the IALD and the DOE will collaborate: • Promoting lighting design principles and technologies that improve lighting quality, energy efficiency, and environmental sustainability. • Developing and disseminating technical information to help the lighting design community assess and specify SSL and other efficient technologies to support DOE programs on lighting quality such as Energy Star and SSL Quality Advocates. • Jointly facilitating forums in which lighting designers can exchange ideas and information with DOE and provide input to DOE lighting program planning. • Encouraging professional lighting designers to participate in DOE lighting projects, such as GATEWAY demonstrations, with particular attention to helping DOE assess lighting quality. During 2008, the DOE and IALD worked together to address many of the issues the MOU outlines. In March 2008, the DOE, IALD, and IESNA co-hosted a Lighting Designer Roundtable in Chicago to solicit the designer perspective on the SSL market and technology issues. A transcript of the debate is available at www.netl.doe.gov/ssl/. Additionally, IALD and IESNA are co-sponsors of the new DOE Next Generation Luminaires Design Competition, which recognizes excellence in the design of energy-efficient LED commercial lighting luminaires.
