According to the U.S. Environmental Protection Agency’s (EPA) Energy Star program, lighting consumes 25 to 40 percent of the energy used in commercial buildings and is a primary source of waste heat.

The Leadership in Energy and Environmental Design (LEED) recognizes the contribution that photovoltaics (PV) make to the sustainability and efficiency of a building project through its Green Building Rating System for New Construction & Major Renovations (LEED-NC Version 2.1).

Drive past hospitals at night and you are sure to see lights glowing in many windows. But as hospital mangers seek advanced lighting technology to reduce energy consumption, that glow is changing. Healthcare facilities want more from their lighting these days.

The energy consumed by residential and commercial buildings represents a significant portion of the total energy used in the United States. Energy drives the U.S. economy and demand will continue to grow along with prices and environmental concern.

All or nothing doesn't necessarily cut it in integrated systems. Now, end-users can integrate all or some of their building management and security functions-letting the level of integration fit the facility.

Coal is too dirty. Uranium is too dangerous. Gas is too expensive. Oil is too political. Solar is too sporadic. Hydro-dams upset the fish habitat.

Photovoltaic (PV) modules convert sunlight directly into electrical energy. Integrating PV into a building will impact its operation. Not only will the PV system produce electric energy to serve building loads but it can also reduce the building's electric demand and air-conditioning heat load.

To enhance lighting inside the big industral box, developers are hiring high-profile architects to design these warehouses and factories with a luxury look. Skylights, glass curtain walls, ornamental awnings and lush landscaping-for warehouses? Yes, it's happening from New York to California.

Adjustable speed drives or ASDs, are often categorized as "sensitive" to power quality phenomena, which means ASD could also stand for "another sensitive device." I am still not sure what "sensitive" means relative to hardware. Susceptible seems like a far better choice of words.
