A city official in San Francisco is calling for extensive reports into the integrity of facades in the city’s downtown after a recent storm caused windows from multiple high-rises to be damaged. According to the San Francisco Department of Buildings and Inspections, four buildings in downtown... View full entry
Once the storm passed, the sight of Punta Gorda may have surprised some people. While it had typical post-hurricane storm debris, downed trees and several flooded streets, a number of homes and buildings appeared largely intact and many showed only minimal damage to their exteriors.
How is it possible that the coastal city wasn’t more devastated by a storm that ranks among the most powerful to ever strike the United States? One major factor, according to some experts, are modern building code
— The Washington Post
While other southwest Florida communities like Fort Myers were devastated, Punta Gorda, a town of about 20,000, was saved thanks to strident code changes enacted in the wake of 1992’s Hurricane Andrew and Hurricane Charley twelve years later. “It’s a demonstration that updated building codes...

If state Rep. Marcus Evans has his way, Chicago will enter the race to build the first offshore wind farm on the Great Lakes. Evans has introduced a bill that lays the groundwork for a proposed wind farm in Lake Michigan, about 10 miles from the shores of the Southeast Side. The bill sets up a fund that would help the state to compete for federal money, including $230 million for port infrastructure projects available from the U.S. Department of Transportation. — Chicago Tribune
Evans introduced the bill, the Illinois Rust Belt to Green Belt Pilot Program Act, in January. The legislation would establish a path toward creating the offshore wind farm by allowing the state to apply for federal infrastructure funds. The proposal promises to create over 1,200 jobs, primarily... View full entry
Social media is buzzing about the unreal damage to the O2 Arena's PTFE-coated glass fiber roof, which tore off during a live performance in the early morning hours Friday. A spokesperson for London’s Fire Brigade told the Evening-Standard there is no “actual collapse” of the roof or... View full entry
Late last month, New York City Mayor Bill de Blasio and the New York City Economic Development Corporation (NYCEDC) announced a 15-year, $191 million plan to make New York City a leader in the offshore wind industry. Called the Offshore Wind Vision (OSW) plan, it ensures the city meets its... View full entry
Although far from soothing, advances in materials science and construction technology, along with experience, are starting to help residents’ day-to-day comfort levels climb along with buildings’ heights. Experts are constantly refining ideal structural shapes, masses, and weights, as well as more obscure features like the multiton machines known as tuned mass dampers, which are designed to limit a building’s sway. — Bloomberg
Residents of Rafael Vinoly’s billion dollar 432 Park tower have begun to pursue legal remedies against the property developers over the building’s annoying sway and a host of other abject failures. Case studies, in addition to advancements in building science could mean a future with fewer... View full entry
A Norwegian company is developing a new technology for floating, offshore wind turbine farms. Unlike traditional wind farms, these are organized in stacked, square grids, standing nearly as tall as the Eiffel Tower. The grids would stand at 1,000 feet tall, composed of multiple smaller...

Earlier this month, the Verrazano-Narrows Bridge was closed due to weather. However, a video posted to Twitter of the bridge undergoing heavy winds went viral due to the sights and sounds recorded. Bridges are built to pass strict safety and construction standards and be capable of withstanding... View full entry
Tougher building rules for skyscrapers have been drawn up by the City of London because of concerns that a high-rise, urban microclimate will generate winds capable of knocking over cyclists and pedestrians.
Developers will have to provide more comprehensive safety assessments of how proposed buildings will affect people on street level, with more robust testing of roadways and pavements using detailed scale models in wind tunnels and computer simulations.

After a series of high-profile skyscraper design controversies, including documented incidents of pedestrians being knocked off their feet and cyclists being pushed sideways into the path of vehicles due to strong skyscraper-generated winds, London is moving to regulate the wind-driven...

The world’s biggest offshore windfarm has officially opened in the Irish Sea, amid warnings that Brexit could increase costs for future projects.
Walney Extension, off the Cumbrian coast, spans an area the size of 20,000 football pitches and has a capacity of 659 megawatts, enough to power the equivalent of 590,000 homes.
The project is a sign of how dramatically wind technology has progressed in the past five years since the previous biggest, the London Array, was finished.
— The Guardian
The Walney Extension is made up of 87 turbines and has a total capacity of 659 MW, enough to power almost 600,000 homes in the UK. This makes it now the largest operational offshore wind farm, however with wind farm supersizing along the British coastline it may not hold the record for long. ... View full entry
Last month, Cavalry 360°, a vast site-specific musical instrument designed by NEON opened on the banks of the North Tyne, UK. The structure uses the force of 32 wind turbines to create an ever-changing sound of the cavalry moving across the landscape—horse’s hooves hitting the ground... View full entry
...So today's engineers battle not only the force of gravity but the the whirling pockets of wind, known as vortices, that can cause towers to shake or vibrate. Failure to do so would make the motion of the building — or "acceleration," as engineers call it — uncomfortably noticeable. — Chicago Tribune
Tunnel tests for Chicago's future third-tallest skyscraper showed that the plan for the building—three thin, interconnected high-rises designed by Studio Gang—would not be able to withstand high winds. According to the engineers, the design for the Vista tower "would result in building... View full entry
[...] has completed advanced wind tunnel tests on The Tower at Dubai Creek Harbour, which is set to be 100 metres taller than the 828-metre Burj Khalifa when complete.
Emaar said the wind tests were crucial in defining the final height and design aspects, while the project’s Spanish-Swiss architect Santiago Calatrava Valls added that they "were an important component in the structural design stage, and we have deployed innovative engineering techniques to confirm the strength of the new icon".

The City of London Corporation has promised a more "rigorous" assessment of developers' predictions of ground winds, following complaints about strong gusts outside the 20 Fenchurch Street Building, better known as the Walkie Talkie.
"I almost got blown over the other day walking up past the building," a sales assistant working nearby said earlier this year. "When I got around the corner it was fine. I was scared to go back."

Because of its size and intense radiation, Texas leads the nation in solar energy potential, but the solar industry has long struggled to get a foothold in the state... and solar energy currently makes up a tiny percentage of the state’s energy portfolio. That’s beginning to change. Improving technology has driven down the price of solar power, making it more competitive with other resources — even without incentives, developers say. — The Texas Tribune
The municipal utility of Georgetown, a Texan city of about 55,000, recently signed a 25-year contract with SunEdison to buy 150 megawatts of solar power as well as 144 megawatts of wind power from the EDF Renewables wind farm through 2039 -- reportedly being the first city-owned utility to take...
