feature Eduard Hueber / archphoto.com Shedding Light Restrictive new codes are prompting NYC designers to come up with bright ideas in lighting technology BY TA M I HA US M A N , P H .D. Tod Williams Billie Tsien Architects 2030. Partnerships with local organizations like the Urban Green Council (the New York Chapter of the U.S. Green Building Council) are helping to enact comprehensive energy reform. New technologies are lighting the way Rapid improvements in lighting technology have already started to reduce carbon emissions. Products like LEDs produce more lumens per watt, or more light for less energy. LED light bulbs can be as thin as a half inch and require only 1/30th the amount of energy as an incandescent bulb, yet still achieve a variety of architectural effects. LED bulbs aren’t yet widely used, partly because they are five times more expensive than linear fluorescent bulbs. Lighting controls and sensors also help reduce energy waste by automatically shutting off lights not in use. Still, the codes are changing faster than lighting designers and professionals can learn new skills and produce new technologies. Realizing that education is key, city officials collaborated with state agencies, professional associations, and non-profit organizations in November 2009 to establish the Green Light New York center. This non-profit lab will provide lighting information to decision makers – including lighting designers, architects, and building owners – and promote the development of sustainable lighting strategies. Green Light is scheduled to open this fall. F or the first time since Edison invented the incandescent light bulb in 1879, the lighting industry is transforming itself. The federal government will retire all incandescent light bulbs by 2014, forcing the design community to find highly efficient, sustainable, and low-cost alternatives. Local, state, and federal energy codes are becoming more restrictive, compelling lighting designers to reduce wattage but not skimp on light. Charles G. Stone, II, FIALD, IES, LEED AP, president of lighting firm Fisher Marantz Stone, says, “The kit of parts we used 10 years ago is almost completely obsolete, and this difference has transformed our business. We have always designed with both daylight and electric light, but now we have to bring very specialized knowledge to projects. It’s an exciting time.” The challenge is especially significant in New York City. Lighting accounts for almost 20% of carbon from buildings, or about a third of commercial energy use. Although New York is among the most energy-efficient metropolitan areas in the U.S., its administration is one of the most aggressive in terms of passing green legislation. City officials hope to reduce greenhouse gas emissions as much as 30% by 28 Oculus Spring 2011 Design for a Change: Buildings, People, Energy http://www.archphoto.com http://www.fmsp.com/
