One of the world’s cleanest new skyscrapers collides with the future

NEW YORK, United States — One Vanderbilt, a commanding new skyscraper in the heart of Manhattan, seems to be reaching for the future. One of the world’s tallest buildings, it pierces the sky like an inverted icicle and fuses seamlessly with an expanding network of trains and other transport at its foundations.اضافة اعلان

It is also the rare skyscraper designed with climate change in mind. It holds a self-contained, catastrophe-resilient power plant capable of generating as much energy as six football fields of solar panels. The building captures every drop of rain that falls on it, and reuses that runoff to heat or cool its 9,000 daily visitors.

“It’s a commercial-grade science project,” said Jonathan Wilcox, a director of engineering at SL Green Realty Corp., the company that owns it.

But One Vanderbilt is also something else. It is already out of date.

Some of the building’s most important green features were the right answer to the climate problem in 2016, when design work was completed. “And then the answer changed,” Wilcox said.

The race against changing climate standardsUnlike many skyscrapers, One Vanderbilt generates much of its own electricity. This was a leap forward a decade or so ago — a way of producing power that saved money for landlords and was cleaner than the local grid.

However, One Vanderbilt’s turbines burn natural gas. And while natural gas is cleaner than oil or coal, it is falling from favor, particularly in New York City, which in recent years has adopted some of the most ambitious climate laws in the world, including a ban on fossil fuels in new buildings.

As that transition happened, SL Green was caught in the middle. Although One Vanderbilt went up relatively quickly, topping out after three years, its owner had to watch as the city’s environmental strategy raced forward.

“Design horizons are longer than people think,” said John Mandyck, chief executive of the Urban Green Council, a nonprofit advocacy group. Still, Mandyck had praise for One Vanderbilt’s climate goals. “We have to celebrate the march of progress,” he said.

Building featuresThe building, which has 73 floors, plus an area on top with bars and observation decks, was 20 years in the making and sits just west of Grand Central Station. Given its marquee location and remarkable ambitions, it opened in late 2020 to less fanfare than one would imagine. At the time, the pandemic was raging and few were in the mood to celebrate a new office tower.

Since then, One Vanderbilt has garnered its share of acclaim, thanks to a popular viewing platform and the transformation of a congested block of Vanderbilt Avenue at the foot of the building into a car-free pedestrian plaza. The skyscraper’s underground plaza is an integral part of East Side Access, merging with the decades-in-the-making nexus of connections between Long Island Rail Road and Grand Central Station, which finally opened last month.

But the building’s flashiest components lie hidden from public view.

On the roof, 400 meters above midtown, cooling towers the size of a Brooklyn brownstone evaporate warm water pumped skyward, discharging a haze similar to that of a football player removing his helmet in February. Like almost everything in One Vanderbilt, the process is not wasted. After losing its heat, the water is sent back downward to cool off machinery dozens of floors below.

On a recent morning, Wilcox and a trio of engineers huddled on the roof, their backs to the sort of knee-buckling view that tourists pay hundreds of dollars to experience from a helicopter. Nearby, five giant fans inside the cooling tower, each the size of a small windmill, quietly spun, recycling energy through the building.

Appealing to climate-conscious tenantsOne Vanderbilt is an example of a new type of office building in which sustainability is front and center in luring tenants, who want to be assured that in addition to enjoying views all the way to the Mario M. Cuomo Bridge and proximity to world-class sushi, their carbon footprint will not tickle their conscience.

All the rain that touches the skyscraper’s terra-cotta and glass facade is transferred to a pair of giant concrete bathtubs and pumped to the cooling towers above.
The truth is that most buildings in New York, big or small, old or new, are bad for the environment. Boilers and furnaces burning fuel in basements are the city’s single largest producer of carbon dioxide, emitting more than double the amount from millions of cars and trucks traveling its roads.

One Vanderbilt, according to its owner, is designed to be more energy-efficient than most new buildings. The structure features several design elements, some exorbitantly expensive, to minimize energy use, such as high ceilings to let in more natural light.

Yet because of the rapidly evolving energy-policy landscape, driven by increasing global concern over climate change, even the most ambitious attempts at sustainability often find themselves facing the possibility of retrofitting the moment the elevator doors open. One Vanderbilt is one such case.

SL Green is New York’s largest commercial landlord, with icons like the Lipstick Building and 11 Madison (the former Metropolitan Life North Building) in its trophy case. “Our stock in trade for many years was taking older buildings, redeveloping them and making them energy efficient,” said Marc Holliday, SL Green’s chief executive.

One Vanderbilt presented the company with a rare opportunity: blank, prime real estate in the heart of Manhattan, with a flood of natural light (meaning less need for electric lights) thanks to neighboring Grand Central — a low-rise, landmark building — and the fact that 42nd Street to its south is a hefty five lanes wide.

Being just steps from the country’s second-busiest train station added to the sense of opportunity. SL Green spent $220 million on transit improvements near the building, partly because of the company’s belief in putting “density where density belongs,” said Holliday.

One striking aspect of One Vanderbilt’s design is its stormwater reclamation system. All the rain that touches the skyscraper’s terra-cotta and glass facade is transferred to a pair of giant concrete bathtubs and pumped to the cooling towers above.

Shifting sustainability lawsThe building’s efficiency, compared with the lumbering machinery of old, has helped One Vanderbilt fill a wall with sustainability awards.

Still, the pace of change has accelerated.

Landlords such as SL Green say New York City’s new laws will force dramatic changes. Unlike energy codes of the past, one of the key laws, which restricts pollution, does not merely apply to new construction: Existing buildings, no matter how small or how old, must gradually comply and retrofit as well, potentially at eye-watering cost.

Like SL Green, all New York landlords will be forced to look into an uncertain future and face stark choices.

For now, the future of New York’s office towers can be seen at 270 Park, a half-finished behemoth rising a few blocks north of One Vanderbilt. It will have no gas line at all. When it opens, it will be the city’s greenest skyscraper ever, owing to the city legislation banning use of fossil fuels in new construction — rules that did not exist when One Vanderbilt was being conceived.

The law, passed in 2021, is new enough that the city, in fact, is still working out the details of how it will be enforced. “In recent weeks, we have reached several important milestones on the implementation of this law,” said Laura Popa, deputy commissioner for sustainability at the Department of Buildings. Popa expected more rules to be added “later this year.”

Wilcox of SL Green supports the city’s efforts to make buildings cleaner, saying that an all electric future “makes sense”. Meantime, One Vanderbilt has welcomed its new tenants. Deep underground, an expanded transit hub rivaling an airport concourse recently opened next door. And dozens of floors above, the building’s powerful turbines twirl in the sky.

Will those turbines eventually end up being replaced with something else? “To be determined,” Wilcox said.
