THE CONTEXT OF ARCHITECTURE He cited his own ongoing discussions with co-speaker Dr. Sheila Kennedy of Harvard University and the architectural firm of Kennedy & Violich and its efforts to demonstrate this new technology in the context of architecture.

Chipalkatti was startled to find that the products being described were incandescent lamps and fluorescent lamps. Because he worked for a lighting company, the data immediately caught his attention.

From page 27... ...
First, they are very energy-efficient light sources. They are already more efficient than incandescent lamps and, because 20 percent of electricity use in the United States is related to lighting, energy experts have estimated a potential annual savings of $30-$70 billion in energy costs by 2020.

From page 28... ...
Dr. Chipalkatti listed a few of the applications in which LED s are being used today, such as traffic signals and signage, but asked rhetorically why applications had not developed further toward low-level lighting for buildings, directional signs along highways, safety signs, decorative signage, and in-ground lights, given the potential for substantial energy savings.

Illuminated LED ceiling tiles would require no extra space, so that tall buildings using solid-state lighting systems would have room for an extra floor every 10 or 12 floors. REMOVING BARRIERS The best way to remove barriers based on misunderstandings or faulty premises, he suggested, is to support an industry-academia-government partnership in solid-state lighting.

From page 30... ...
In the United States, for example, the use of an incandescent traffic-signal standard makes it inherently difficult for local governments to adopt less expensive LED technology. A NATIONAL LIGHTING INITIATIVE The next step, suggested Dr.

From page 31... ...
That is, users will probably not screw LEDs into the traditional Edison base that holds our incandescent bulbs. Solid-state lighting technologies will suggest entirely new sets of materials and ways to deliver and use light that go far beyond what she called the current bulb culture of lighting.

From page 32... ...
Kennedy's design research team are people of different levels and skills, including industry leaders, materials scientists, technical people from major manufacturers, professionals, and graduate students. She and her colleagues began by establishing parameters for the design research process: They would plan for systems based on technology that was not yet available.

From page 33... ...
She also described a floor system called a low-velocity floor that consists of shapes of engineered lumber rolled out like wallpaper beneath a thin, compressed plenum, or mechanical surface. Then a cool, thin cushion of air can be introduced to distribute cool air far more efficiently than typical air conditioning blown downward from a ceiling.

The first, in the theater district of Boston, uses structural glass manhole covers with solid-state lighting technology embedded in them. The second, in New York City, is a commission for seven commuter ferry terminals along the East River to be equipped with solid-state lighting connected to photovoltaic power sources.
