Engineering wind-resilient structures and spaces is a complicated endeavor that relies on both human ingenuity and science. Projects must also mesh with other environmental factors, including falling snow and ice, snow loads and solar conditions. Consulting firms tap detailed climatological data, local wind data and more to grasp how wind affects a structure in a particular spot. But that’s only a start.

Since early 2016, a new 3,600-ton capacity geothermal system has been providing cooling for the entire terminal building at the Nashville International Airport, significantly reducing the facility’s use of both electricity and water. The nearly $10.4 million project finished three months ahead of schedule and under budget.

“Gridlock Sam” Schwartz has always had an outsized presence in his endeavors. “He is, inarguably, the most beloved transportation engineer alive,” says Charles Komanoff, a New York City transport economist, who then adds with a smile, “Admittedly, there’s not much competition.”

In a creative blend of old and new, the fabled Steinway Hall on New York’s West 57th Street will soon begin a new career, its atrium serving as the elegant main entry for a supertall high-rise now under construction on the adjacent site. Featuring progressively greater setbacks on its northern face for a feathered rather than stepped profile, the new 1,428- foot tower’s glass curtain walls will offer unparalleled views of Central Park to the north and the Manhattan skyline to the south. Hearking back to the quality and detail of historic New York towers, the shear walls on the east and west are being clad with a custom-cast terra cotta, bronze filigree and glass façade.

What about North American cities? The index found they have a lot to learn from their international peers. Vancouver was the continent’s leader at 23rd in the overall ratings, while U.S. cities failed to enter the top quartile. The closest contender was New York City at 26th place…Infrastructure differences help explain why European cities outpaced U.S. and Canadian counterparts. Many European urban centers were settled before the automobile age and, as a result, are densely settled and supported by well-established public transportation systems. However, many American cities outside the Northeast grew with automobiles in mind. “Carcentric designs can lead to urban sprawl and a large carbon footprint, with enormous costs,” Dalkmann says. “Those are fundamental challenges for U.S. cities in terms of sustainability.”

AMERICAN COUNCIL OF ENGINEERING COMPANIES (ACEC) Written by Gerry Donohue Battery storage is not yet ready for prime time. It is just too expensive. Although it has cost-effective applications in a few niches, such as island grids or locations where technical constraints require a non-wired solution, it doesn’t pencil out for large-scale energy storage. That […]
