New York City’s dense urban landscape is populated with more than a million buildings that annually consume $15 billion in energy and generate 75 percent of the city’s carbon emissions. The 22,000 largest buildings, concentrated largely in Manhattan, account for roughly 45 percent of total floorspace and energy consumption. READ MORE

Amalgam technology, fairly common among plug-in compact fluorescent lamps (CFLs), is now available in linear T5HO, T5VHO and T8VHO fluorescent lamps, making fluorescent lighting competitive in many high-intensity discharge (HID) applications. Fluorescent lamps produce visible light through a gaseous discharge process called fluorescence. READ MORE

In a perfect world, a lighting manufacturer would respond to interest in one of their products by assuming the cost of installing samples in an exact mockup of the actual space being designed. Then, the manufacturer would hire people to work there for a while and conduct a postoccupancy survey on their satisfaction with the lighting. READ MORE

Tight credit and weak demand for new facilities pushed private nonresidential spending into a deep slide in 2009, while public construction got a boost from federal stimulus money. Considering that more than 30 states and 130 cities encourage or require Leadership in Energy and Environmental Design (LEED) certification for public construction, many of these projects are green.

“CFLs in America: Lessons Learned on the Way to Market,” published by the Department of Energy (DOE), concludes that technical and quality problems with early compact fluorescents snowballed into major obstacles to acceptance by consumers and retailers. READ MORE

Some of the most dramatic lighting performance gains can be achieved by adopting solid-state lighting in the home, where incandescent lighting has met its match with products that combine the efficiency of compact fluorescent and the quality of halogen. READ MORE
