NCQLP Announces Test Results – 2002 Examination Joseph M. Good, III, President, NCQLP, announced that 209 lighting practitioners sat for the 2002 exam. With a pass rate of 78.5 percent, the roster of lighting certified individuals have been increased by 154 full LCs and 10 Intern LCs. The LC class of 2002 now brings the total number of LCs to 1127. The National Council on Qualifications for the Lighting Professions is a non-profit corporation founded in 1991 to serve and protect the well-being of the public through effective and efficient lighting practice. Through a peer review process, the NCQLP establishes the education, experience and examination requirements for certification in the lighting industry. Thirty-six percent of those who have sat for the LC exam over the past three years identify themselves as lighting designers/consultants. The two next largest groups are electrical engineers (16 percent), and manufacturers’ representatives and sales representatives (12 percent). Thirty-four percent list experience levels at 6-10 years, with another 38 percent indicating 11-20 years of experience. An average of 50 percent of exam takers hold bachelor degrees; 18.7 percent hold advanced degrees. Sixty-eight percent identify themselves as members of the IESNA; 14 percent, the IALD. Four percent each cite their primary affiliation as AEE, IEEE or the AIA. This year, sixteen graduate and undergraduate students in lighting took the LC examination as participants in the NCQLP Intern Program. An accredited college offering a minimum of 12 credit hours in lighting or lighting related courses can apply to be a part of this program. Seven students from Penn State University, four students from Rensselaer Polytechnic Institute, and five from Parsons sat for the LC examination; ten of those who took the examination are now designated Intern LCs. The Intern LC program was partially funded by two grants from the Nuckolls Fund for Lighting Education and additional grants from the Lutron Foundation and the Golden Gate Section of the IESNA.

PHOTOS: JILL CODY The Kachel Fieldhouse includes recreational multipurpose courts and a competition 200 meter running track. Our design addresses the lighting requirements of various sports, while meeting rigorous sustainable design objectives. Managing Glare After establishing the architectural design to provide an adequate level of daylight, the next step focused on assessing and resolving problems with glare. Direct sun or a very bright diffuse surface in a athlete’s field of view were central concerns. Diffuse glazing is one technique for controlling direct sun, but it AWELL-CONDITIONED ATHLETE HGA and The Weidt Group partner to create an efficient home for athletics Aspace for athletic competition and recreation, efficient and simple to operate, with design features making it a model for future facilities. Simply put, these were the goals of the design team and owner. The DLK/Kachel Fieldhouse addition to the Williams Center at the University of Wisconsin – Whitewater was designed to create an intercollegiate competition facility for indoor track meets and to expand recreational and intramural space for students on campus and the surrounding community. The project was also designated to establish a model design process for incorporating sustainable design elements into this and future projects for the State of Wisconsin. To this end, the architects and engineers at Hammel, Green and Abrahamson (HGA) worked with energy consultants The Weidt Group and State of Wisconsin facilities development personnel to develop energy savings strategies that included reduced energy consumption for lighting loads and the use of daylighting. Daylighting Design It was once said by a wise man that daylighting is like taking a sip of water from a fire hydrant. The sun is a powerful light source so bright that it can seldom be used directly for most interior visual environments unless controlled properly. The best source of daylight is from the sky, not the sun, so glazing orientations for a building need to maximize the facades where the sunlight can be easily controlled. The north orientation, and then the south, are desirable in northern latitudes, while east and west facades are problematic due to low sun angles, and are difficult to control costeffectively. During design, several variations on architectural roof forms and fenestration alternatives were studied using physical daylight models and energy simulation software. Among the alternatives studied: flat roof vs. barrel vaulted; Low-E clear glazing vs. translucent, insulating glazing (e.g. Kalwall); active and passive sunlight control features; and the use of skylights. Vertical fenestration was evaluated on various combinations of the north, south, and west faces of the building. The east face of the building was not evaluated because it abuts the existing building. Several of the passive sunlight control features under consideration, including internal light shelves and redirecting glass block, were eliminated due to their associated construction costs. Some glazing placements and types were eliminated due to unacceptable glare created by direct sunlight hitting the playing surfaces during large periods of the year, while others were eliminated due to owner preferences. The architectural design finally selected was a barrel vault roof with translucent, insulating glazing on the north, south and west faces. Based on physical scale-model measurements, the barrel vault roof form provided 35 percent greater daylight levels in the center of the fieldhouse compared to a flat roof configuration. This was due to the increase in window height on the north and south walls compared to the flat roof. Adding glazing high along the west wall increased daylight levels further, improving daylight uniformity from north to south. 36 LD+A/March 2003 www.iesna.org glare by creating an extremely bright surface when exposed to direct sunlight. Using low visible light transmittance (VLT) glazing can reduce surface brightness. However, low VLT glazing also reduces the amount of interior daylight available throughout the year. Historic weather information for Whitewater, Wisconsin showed that a significant percentage of days could be expected to be overcast. Selecting VLT characteristics at this building site became a balancing act between reducing glare during sunny conditions and depressed interior daylight levels during the majority of the time it is overcast. Instead of selecting a “one size fits all” approach to balancing the VLT needs on the project, a customized approach was used, “tuning” the VLT to the requirements of each façade orientation, balancing the (top) Three translucent clerestories allow playing surfaces to be washed with 5-15 footcandles of natural light on a partly cloudy day. (bottom) Visible light transmittance values were carefully selected to take advantage of the available daylight without creating discomfort glare for players using basketball and tennis courts. www.iesna.org still presents the potential to produce impacts of glare, interior light level, and energy performance. On the west window wall a very low VLT (15 percent) was selected to ensure the diffuse surface would not be too bright within the field of view of the multi-sport playing courts. The south windows with an overhang had less exposure to sunlight throughout the year, allowing a higher value of VLT (35 percent). On the north, transparent glass could have worked, but to maintain architectural consistency, diffuse glazing with the highest available VLT (50 percent) for the glazing product selected was used.
