When Chinese President Hu Jintao visited Washington, D.C., last week, he summed up his view of the Sino-U.S. economic relationship, saying, “We should abandon the zero-sum Cold War mentality, view each other’s development in an objective and sensible way, respect each other’s choice of development path and pursue common development through win-win cooperation.” Photo: Courtesy of Jushi Group Ltd.

The truck runs on a diesel-electric hybrid power system, and it has been engineered to carry a high payload with a lighter-than-average structural frame. It may sound like an ad for the latest “green” pickup, but this truck consumes hundreds of gallons of fuel per hour, and its payload is measured in the hundreds of tonnes. In an industry in which productivity and cost-per-tonne are everything, the designers of Liebherr’s prototype TI-274 mining truck always are looking for a little more efficiency. The truck currently is being put through its paces at Liebherr’s testing grounds near Emporia, Va., and, depending
At the site of the new Institute for Critical Technology and Applied Science building at Virginia Polytechnic and State University, students, faculty and visitors are asking questions about green construction. However, they are not inquiring about the 45,000-sq-ft academic building that will be seeking LEED Silver; they are asking about the colorful reMOD trailer next to it. Manufactured by Williams Scotsman Inc. and being used by project manager Skanska USA Building, the construction trailer features many design choices intended to reduce its environmental footprint. Construction trailers are not an obvious candidate for sustainable design. As the trailers are temporary by
Heating, ventilating and air- conditioning systems are often invisible to the occupant. Hidden behind walls and snaking through ceilings, HVAC is noticed only when it breaks down.

At the site of a new $8.5-million, three-story dormitory at Southern Nazarene University in Bethany, Okla., the Versa-Floor HR floor system is getting its first real-world application. The prefabricated steel deck is joined and fitted with channels on the ground. Then, the 30 x 30-ft steel panels are lifted into place by a crane. Once connections are made to the structural columns, it’s almost ready for the concrete slab to be poured. “That’s the genius of the system,” says Aaron Ford, project manager on the dormitory project and associate principal with structural engineering firm L.A. Feuss Partners, Dallas. “We build
Getting energy-efficient design into school construction can be tough, but the Gen7 modular-classroom building from American Modular Systems, Manteca, Calif., fits many of the latest energy-efficiency advances into one package, bringing the cutting edge of green technologies to modular school construction. Photo: American Modular Systems Gen7 modular classrooms are showcases of sustainable technologies. Introduced at the Green California Schools Summit 2009 in Pasadena, Calif., in December, Gen7 is being touted as a “grid-neutral” modular-classroom solution for California school districts. “Gen7 is a loaded model, with every possible option,” says Tony Sarich, vice president of operations for AMS. “It’s not the

Mapping existing broadband service is a requirement for states angling for a piece of the roughly $4.2 billion in matching American Recovery and Reinvestment Act funds for high-speed Internet expansion. But with a deadline approaching, states and municipalities have been scrambling to find the data. Photo: Connected Nation Michael Ramage (left) explains BroadbandStat at its debut at a Congressional policy exhibition in Washington, D.C., where it attracted interest from local officials seeking to expand broadband. Now, a new tool is available to help. In February, Connected Nation, a Washington, D.C.-based nonprofit dedicated to expanding high-speed Internet access, launched BroadbandStat, a
