'Blobitecture' Changing Cities' Skylines
HAMBURG, Germany—Unconventionally shaped, right-angle-free buildings are increasingly popular in city centers around the world. Emporis, the international provider of building data, has compiled a list of what it considers the most spectacular examples of "blob architecture," or "blobitecture." The odd building designs, made possible by computer-aided processes, evoke often comical nicknames from the general public, such as "Misshapen Egg," "Motorcycle Helmet" and "Onion." The Experience Music Project in Seattle, with its soft, flowing form, has laid claim to the name "The Blob."

Sneaking Through a Duct System: A Cautionary Tale
MILWAUKEE—Staffers at a Milwaukee veterinary hospital recently had their morning interrupted by sounds they could not locate. After one employee heard a call of "help," they called 911. Responders found a 19-year-old man trapped in the recovery unit of the building’s ventilation system. The fire department cut him out of the ventilation unit, where he had been trapped for roughly 11 hours. He emerged naked and bleeding. The teen apparently took his clothes off and climbed into the ventilation system to try to steal morphine and ketamine. However, he began panicking as the shaft narrowed and fell 10 ft (3 m) through the ventilation system to the ground level in the 3 ft by 2 ft (0.9 m by 0.6 m) recovery unit. His injuries occurred as he fell through halos of three-inch screws in the ventilation system. He caused $5,000 in damage trying to hammer his way out.

Study Finds Humidity Reduces Airborne Flu Virus
ATLANTA—A recent study by the U.S. National Institute for Occupational Safety & Health (NIOSH) found that airborne transmission of the influenza virus is significantly reduced by maintaining an environment of 43% relative humidity (RH) and above. To test the effects of humidity on airborne influenza, aerosols of flu virus were “coughed” into a room’s atmosphere by a mechanical manikin at humidity ranging from 7% RH to 73% RH, while the air intake from a "breathing" manikin in the room was monitored. The air inhaled by the breathing manikin showed that at ≤23% RH the airborne flu virus retained 71% to 77% infectivity, while at ≥43% RH infectivity dropped to just 15% to 22%. The study showed that inactivation of the virus at the higher humidity occurred rapidly after coughing, with most of the decline occurring in the first 15 minutes.

Nonresidential Architecture Activity Continues Steady Growth, Says AIA
WASHINGTON—Continued increases in billings at U.S. architecture firms occurred in August, according to the American Institute of Architects (AIA). AIA's Architecture Billings Index (ABI) score for the month reflected the strongest growth in activity in six months, and marked the twelfth time in the last 13 months that design activity has increased nationally. The ABI assigns a score to the level of construction spending over time. AIA says that the strength of recent readings in the ABI, coupled with the extended period that architecture firms have been reporting generally favorable conditions, points to an impending healthy upturn in nonresidential activity. This matches the recently released results from the AIA’s "Consensus Construction Forecast Survey," which forecasts nonresidential construction spending picking up in the fourth quarter of 2013 and accelerating through 2014.

Green Roofs Installed on Empire State Building
NEW YORK—The Empire State Building now features four green roof systems, with a total area of nearly 10,000 ft2 (929 m2). Green roofs have been installed on four rooftop areas: the 21st floor (east and west), the 25th floor (northwest), and the 30th floor (west). The green roofs on the 21st floor feature rooftop patios with outdoor furniture for building tenants. The green roofs are constructed with a German-designed system that uses prevegetated mats.

Making the Case for Energy Metering
By Jim Plourde
Meters provide information that can empower building owners and operators to make sound decisions about how their buildings use energy. Without the appropriate meters, they will not have the necessary tools to do more than just collect information. This article covers goals of energy metering, specifying the right meters, and analyzing and leveraging data.
