Comcast Promotes Green!

MATERIAL STATISTICS

Philadelphia's tallest building was constructed with a sustainable design that makes it eligible for LEED Certification from the US Green Building Council. The interiors and exteriors of Comcast Center will bear the eco-friendly mark.

The floor heights vary from 13ft to 17ft, thus providing sufficient ventilation and natural light to every part of the building. These design aspects also reduce the burden on electricity.

Recycled materials were used for the carpeting in Comcast Center. Building systems, like heating and air conditioning, are controlled floor-by-floor to avoid excess consumption. The paints used carry minimal volatile organic compounds and external window screens have been installed in the winter garden to check the sunlight.

"Philadelphia's tallest building was constructed with a sustainable design."

Steel frames and glass are the main structural components of the Comcast Center. The stairs of the building are extra wide to accommodate firefighting needs in case of emergency. The contractors have also installed emergency lighting in the stairs. Comcast Center has 35 high-speed elevators.

Solar technology is greener than ever
HPC Film is the core component of Prism Solar’s Holographic Planar Concentrator™ (HPC) technology, which enables solar modules to generate the same yield as conventional modules while using 50-75% less photovoltaic material. Reducing the amount of expensive silicon in a solar module greatly lowers material cost. It also results in manufacturing savings through reduced assembly and processing requirements. Prism Solar HPC (holographic Planar Concentrator) Film HPC Film consists of several gelatin-on-PET plastic layers. Each film is imprinted with a holographic optical element. Together, these elements diffract the wavelengths (400-1100nm) that can be converted to energy by solar cells. HPC Film diffracts usable wavelengths of sunlight to increase efficiency of solar cells HPC film diffracts usable wavelengths of sunlight and guides them to the solar cells. The usable energy is guided to the cells, resulting in up to a 3X concentration of energy per unit area of photovoltaic material. Prism Solar panel employing HPC Film HPC Film replaced 2/3 of the silicon in this solar module. HPC Film collects sunlight over a wide range of incident angles, and collects diffuse and reflected light as well, keeping cells near peak efficiency over longer periods of the day and season. Harvesting energy over 360-degrees is what allows HPC modules to generate such high yields, even in low light conditions, with so little silicon or thin film photovoltaic material. HPC Film has the unique feature of "Passive Tracking" which collects solar energy over a wide range of angles for high efficiency througout the day and season. Through 360-degree collection, HPC solar modules collect more energy over a wider range of angles, for high efficiency throughout the day and year. Finally, HPC Film keeps solar cells operating at or near their peak performance temperature. Wavelengths of sunlight that cannot be converted by the solar cells are allowed to pass through the film and panel, rather than being absorbed and converted to heat. This “spectral selection” feature keeps cells operating close to their ideal temperature curve without mechanical cooling—even at 3X concentration. HPC Film has been field proven in installations for more than seven years and has shown no significant degradation or loss of performance. The highly stable film improves the efficiency of solar modules based on monocrystalline silicon, thin film, or virtually any PV material. © 2009 Prism Solar Technologies, Inc. | 180 South Street| Highland, New York 12528 | Phone 845 883-4200 | Fax 845 883-4394 | info@prismsolar.com
