Airport Lands Upgraded HVAC System
The system will allow airport operators to control the climate inside all 360,000 square feet of the terminal. The system also will save the city 22% to 25% in utility costs.
HVAC Design Changes May Enhance Energy Efficiency
Samsung says it is working toward enhancing efficiency in heating, ventilating and air conditioning systems through design.
Sensors Detect Damage in Bridge Structures
Researchers use sensors to “listen” to a collection of signals from bridges and other mechanical structures that may help diagnose structural changes or damage.
Cement Materials: An Overlooked Carbon Sink?
The natural carbonation process of cement materials represents a large and growing sink of CO2.
Dome Now Covers Chernobyl Nuclear Site
The structure is about 500 feet long, has a span of 800 feet, and is 350 feet high. It is designed to last at least a century and is intended to prevent any additional release of toxic material from the reactor.
Rock Star: LEDs Electrify Energy Management Efforts
LED technology can beat almost every other lighting technology and opens the door to new levels of energy use and control that can have grid-scale impacts.
Biocomposite Bridge Opens in the Netherlands
To develop the biocomposite, fibers were stuck to a biological polylactic acid foam core, after which a bioresin was sucked into the fiber layers using a vacuum to produce a strong girder.
Mood Ring Materials Could Detect Cracks in Bridges and Aircraft
Mixing fluorescent nanoparticles and clear polymer resin yields a novel sensor that changes optical properties under stress.
Remote Sensing Spots Infrastructure Cracks After Disasters
The technology includes the camera hardware, mounted to a plane or unmanned aerial vehicle, and the software, which analyzes the pictures taken.
Video: Worried about the airline losing your luggage? A ten-cent technology could help. Infrastructure failures are likely to grow says a new study. German engineers work to preserve a scenic railway.

Smart bridge sensors
The project is designed to showcase the future of smart, sustainable, user-centered transportation infrastructure that helps to monitor structural and environmental health.
Factors Leading to Concrete Bridge Cracks
When the current infrastructure was built in the 1950s, it was constructed for that era's traffic demands, with little focus on maintenance.
Flexible Materials Help Keep Bridges Open in a Big Quake
Bridge columns built using memory-retaining nickel/titanium rods and a flexible concrete composite returned to their original shape after a 7.5-magnitude tremor.
More Infrastructure Failures Likely as U.S. Assets Age
Fitch says in its 2016 Water and Sewer Medians report that capital spending dropped to the lowest level the agency has observed since publishing its annual medians.
Ultrasonic Technology Diagnoses Bridge Repair
Cement suspensions will be injected into the damaged areas of the arched bridge in such a way as to preserve the original appearance of an historic viaduct.
Robots Help to Build Modular Bridge
Robots may reduce health and safety risks by removing manual lifting and handling, while enhancing the quality of the weld, helping to ensure consistency and increasing output.
Bad Roads Can Cost You Money
Driving on poor roads increases consumer costs by accelerating vehicle deterioration and depreciation, increasing the frequency of required maintenance and boosting fuel consumption.
Electricity Used to Track Water, Identify Concrete Degradation
The technology can determine where and whether water is infiltrating concrete, as well as how fast it is moving, how much water there is and how existing cracks are influencing the water movement.
Photos Used to Catalog Building Damage
The researchers have to train the algorithms to recognize scenes and locate objects in the images.
Could Bacteria Create Building Foundations?
Researchers are modifying E. coli bacteria to create a "gene circuit" that would enable the bacteria to respond to their environment by producing biocements.
