Building Owners Want 'Smart' Buildings, Says Survey
FRAMINGHAM, Mass.—Half of building owners currently use "smart" connected systems, such as lighting, appliances and security systems in their facilities, according to a recent survey. An additional one-third of respondents to the IDC Energy Insights survey said that they will use such technologies within the next year. Meeting sustainability goals was the most-cited reason for responding building owners to turn to "smart" systems.

Study Demonstrates Importance of Commissioning for Daylighting Control
MADISON, Wis.— A recent project by the Energy Center of Wisconsin (ECW) sought to measure and demonstrate the importance of commissioning daylighting controls. The median daylighting control (daylight harvesting) system was saving 23% of lighting energy, including impacts on heating and cooling, during the initial measurements. However, the average effectiveness of the controls (the energy saved versus energy saved with ideal control) was only 51%. After commissioning and performing basic startup/tuning tasks, the researchers were able to increase median lighting energy savings to 63% for each kW of lighting controlled.

Tyson to Pay Almost $4 Million for Ammonia Refrigeration Accidents
ST. LOUIS—Tyson Foods has agreed to pay a $3,950,000 penalty as a result of accidental releases of anhydrous ammonia at facilities in Iowa, Kansas, Missouri and Nebraska, according to the U.S. Environmental Protection Agency (EPA) and the Justice Department. The company uses anhydrous ammonia as a refrigerant. As part of a consent decree, Tyson has agreed to conduct pipe-testing and third-party audits of its ammonia refrigeration systems to improve compliance with Clean Air Act requirements at all 23 of the company’s facilities in the four Midwestern states. The settlement stems from a series of eight separate incidents between 2006 and 2010 that resulted in property damage, multiple injuries, and one fatality.

Floating Data Center Ready for Maiden Voyage
SUNNYVALE, Calif.—A California company has developed a floating wireless data center designed to float continuously in the ocean for months, capturing and processing data to be beamed back through several wireless technologies. The Wave Glider SV3, by Liquid Robotics, is able to power the large collection of equipment suspended beneath its floating top layer with a combination of power from photovoltaic solar panels and wave energy, converting the motion of the ocean into electricity. The SV3 is meant to carry a large load of sensors designed to serve potential users such as the oil and gas industry, fisheries and the military. The company hopes that the Wave Glider SV3 can be used as a floating server rack.

Despite Storms, Companies Still Want Data Centers in New York
NEW YORK—Despite the damage caused by storms Irene and Sandy in the New York metropolitan area in the last two years, businesses still want to expand their data center capacity in the low-lying, seemingly storm-prone area. According to a new survey for data center service provider Digital Realty Trust, 65% of the companies that said they definitely plan to expand their data centers want to do so in New York, more than any other city in the world. This counters speculation that big companies would locate more of their new data center operations farther from the coast. Overall, 98% of companies said they plan to expand their existing data center capacity.

Philadelphia Skyscraper's Side to be Used for Pong Tournament
PHILADELPHIA—Later this month, gamers could get the chance to play the classic 1970s arcade game Pong on what is reportedly one of the biggest video game screens in the world. On April 19 and April 24, Drexel University gaming professor Frank Lee, Ph.D., will host a Pong gaming tournament on the north side of the 29-story Cira Centre in Philadelphia. About 100 players will use arcade controllers about a half mile (0.8 km) away from the 437 ft (133 m) building to control its LED lights. Brandywine Realty Trust, which owns the building, has given approval for the tournament.
