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).
Antioch Community High School might seem just like any other American school. It has the typical heating system, lighting and amenities, including a heated swimming pool. But the unobtrusive power station in the school parking lot tells another story.
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.
Energy codes establish the minimum requirements for the performance of new buildings. States have typically adopted either the ASHRAE/IESNA Standard 90.1 or the International Energy Conservation Code (IECC) as their energy code for commercial buildings.
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.
Advancements in lamp and fixture technology, new approaches to design and the influence of the International Dark-Sky Association (IDA) are making waves in the outdoor lighting world. “This is the most exciting time ever in the lighting business.
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.
We have a couple of items for April. One is an information update from a previous column. Another concerns new sustainable building requirements, which is very topical. It is a bit of a head's up on how these requirements may have hidden costs you might miss in a bid.
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.
On three faces of the new downtown Los Angeles headquarters of the California Department of Transportation (Caltrans), 2,000 innovative outdoor metal panel scrim louvers open and close in vertical banks.
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.
Photovoltaics (PV) are semiconductors that convert sunlight directly to direct-current (DC) electric power. Photovoltaic technology has been used for years in specific applications where conventional utility service is not readily available or practical.
There's a growing urgency in the development of “green” or “smart” building, and learning to install its energy infrastructure-which is called integrated building systems (IBS) and involves tying together HVAC, electrical, security, lighting and fire alarm systems-could well be a boon to contractors
