Adrian Smith + Gordon Gill Architecture Wins Competition to Design Wuhan Greenland Center, to Be the World's Fourth-Tallest Building

June 21, 2011

Adrian Smith + Gordon Gill Architecture is pleased to announce that it has won an international competition to design Wuhan Greenland Center, which at 606 meters (1,988 feet) will likely be China's third-tallest building, and the fourth tallest in the world, when completed in about five years. Construction is scheduled to begin this summer in Wuhan near the meeting of the Yangtze and Han rivers.

A project of the Shanghai-based Greenland Group, the 119-level Wuhan Greenland Center will be comprised of about 300,000 square meters of floor area, including about 200,000 sm of offices, 50,000 sm of luxury apartments and condominiums, a 45,000 sm five-star hotel, and a 5,000 sm, 27-meter-tall private club with spectacular views at the tower's penthouse level.

AS+GG is leading an interdisciplinary design team that also includes the structural engineering firm Thornton Tomasetti as well as PositivEnergy Practice, an energy services, engineering and consulting company. The other finalists in the design competition were the Chicago office of Skidmore, Owings & Merrill; HOK Architects; GMP Architects; and P&T Architects.  

The project reunites the Greenland Group with Adrian Smith and Gordon Gill, who designed the Nanjing Greenland Financial Center, and Robert Forest, who managed the Nanjing design process, all while at SOM. Nanjing Greenland Financial Center's Zifeng Tower, currently the world's seventh-tallest building at 450 meters (1,476 feet), opened last fall.

"We're thrilled to be working with the Greenland Group once again," Adrian Smith said. "We had a very good experience on the Nanjing project, and we think Wuhan promises to be just as rewarding. As always, we're extremely impressed with Greenland's commitment to good design and quality construction. "

"Wuhan is an exciting and important project for our firm as we continue to advance our ideas about performance-based supertall tower design," added Gordon Gill. "We look forward to building on past experience on similar projects, with particular emphasis on the relation of architectural form and performance as they pertain to structural wind loads. It's very rewarding to be working with the Greenland team. We enjoyed our time on Nanjing and look forward to creating a world-class project with them for Wuhan."

Still under design, Wuhan Greenland Center features a uniquely streamlined form that combines three key shaping concepts–a tapered body, softly rounded corners and a domed top–to reduce wind resistance and vortex action that builds up around supertall towers. The building's extremely efficient aerodynamic performance will allow it to minimize the amount of structural material (and its associated embodied carbon) needed for construction.

The tower's three corners rise from its tripod-shaped base and taper upward, culminating in an arched tip above the dome at the top. The corners will be of smooth curved glass, contrasting markedly with the more textured curtain wall cladding the body of the tower. The curtain wall will enclose a composite concrete core with steel framing. Apertures in the curtain wall at regular intervals will assist in venting wind pressure against the tower; the apertures will also house window-washing systems and air intake and exhaust systems on mechanical floors.

"One of the distinctive features of this project is the innovative introduction of vents at the tips of the three legs of the tower at vertical quarter sections that will reduce wind pressure on the tower and reduce the vortices that can cause horizontal acceleration of movement," Smith said. "This feature, along with the elegant tapering of the tower, is an essential element in this performative design concept."

"It's an honor to be working with Greenland Group again on such a significant project," AS+GG partner Robert Forest added. "Wuhan Greenland Center continues our commitment to providing designs that enhance China's ability to provide for an increasing population density while striving to reduce energy use and carbon emissions without compromising design quality, performance and cost."

Other planned sustainable elements of the project include:
•    Energy recovery using an enthalpy wheel integrated into the ventilation system; this captures energy from the building's exhaust systems and uses it to pre-heat or pre-cool air entering the building.
•    A greywater recovery system, which takes waste water from the hotel laundry, sinks and showers and reuses it in the building's evaporative cooling system.
•    A high-efficiency lighting system, which uses low-energy-consuming ballasts and lamps to reduce required power consumption.
•    A daylight-responsive control system, which automatically turns off electric lights when sufficient daylight is available.
•    Water-conserving low-flow plumbing fixtures, which reduce the total amount of potable water required as well as the associated pumping energy.

In addition, the AS+GG Interiors studio is developing the tower's fluidly sculpted interior public spaces, many of which reflect the tower's exterior silhouette. The conical silhouette is visibly echoed in the entrances to the primary elevator bank from the main lobby, as well as in the shapes of the elevator cabs and other public spaces. The lobbies and other amenity spaces within the tower also feature sweeping, fluid lines and a neutral blue-gray palette that recalls the reflective glass of the exterior wall. The transparency of the ground-floor lobby wall allows views from inside toward the entry canopy drop-off areas, establishing a seamless relationship between the interior and exterior.

Ritz-Carlton Signs Two New Hotels in China

Ritz-Carlton has signed agreements with the Shanghai Greenland Group, one of China’s premier property developers, for the development of two new Ritz-Carlton hotels in China - The Ritz-Carlton, Wuhan and The Ritz-Carlton, Dalian.

The Ritz-Carlton, Wuhan will be located at the top of the 606-meter-high Wuhan Greenland Center, while The Ritz-Carlton, Dalian will occupy floors 64-81 of the 518-meter-high Dalian Greenland Center.

The agreement will see The Ritz-Carlton with 13 hotels in China by 2017.

Herve Humler, The Ritz-Carlton president and chief operating officer, said, “We are delighted to be working with such dedicated and ambitious partners as Greenland on these two stunning hotels. These buildings will set the stage for stylish and contemporary Ritz-Carlton hotels in these two major Chinese cities. The Ritz-Carlton has long been known in China as the leading provider of luxury lifestyle experiences, and these hotels will allow us to showcase our product to a wider audience in China and show that we really do take luxury to new heights.”

Scheduled to open in 2017, the 330-room The Ritz-Carlton, Wuhan will be located in the center of the Wuchang Binjiang CBD. MICE facilities will include more than 2,500 square meters of meeting space, while those looking to relax will be able to take advantage of an heath club, pool and spa.

The hotel will offer a choice of dining options and bars including an 170-seat three-meal restaurant and 150-seat Chinese restaurant which will feature 12 private dining rooms and will focus on world-class regional cuisine. The hotel will also have a lobby lounge capable of hosting 70 guests and a 50-seat Ritz-Carlton Bar with views over the city. In addition to these restaurants, the hotel will offer a selection of food and beverage options on the 119th floor of the hotel which will be at the very top of the building and encased in a glass dome were dinners can enjoy their meals at an elevation of 545 meters.

Located in the heart of Dalian’s Donggang CBD, the 300-room Ritz-Carlton, Dalian will form part of a mixed-use development and will offer a variety of restaurants bars and other facilities to its guests.

The hotels will further strengthen the relationship that Marriott International – the parent company of The Ritz-Carlton – has with Greenland, which already owns three hotels with the company.

china is in for major tower in the park syndrome 15 years from now.

Zapatan Jan 16, 2012 8:54 AM

China's in for a bubble collapse aswell by that time I would say ^^

The first couple of photos show caissons already in place. Caissons are part of the foundation for a structure. Though I am not sure if these caissons are for the tower of this thread or for the other proposed strucutures surrounding this highrise.

The three piling rigs above the white cement truck are for the 600m tower- it's now U/C for sure!

BTW, height seams to have been raised to 636m to beat Shanghai Tower. Shame they don't know about PingAn.

Found a floorplan for the hotel.

Doesn't it seem time for this thread to move to Supertall construction?

Tom In Chicago Oct 14, 2012 1:25 AM

Sure looks like it's under construction to me. . . moving to appropriate sub-forum. . .

. . .

Phat Stanley Oct 14, 2012 8:44 AM

Yea... Thanks Tom! :banana: Wow... I feel like I accomplished something. :haha:

Now we can all start enjoying the rise of this awesome supertall. Personally, I love the renders of this thing. Can't wait to see structure and cladding.

Another tower in the middle of nowhere, like Goldin Finance in Tianjin.
That's a shame. It could have nicely topped an existing skyline.

Phat Stanley Oct 14, 2012 6:49 PM

Well that's true in one respect, but here's some other thoughts:

Sometimes fantastic towers need to stand apart. Would Taipei 101 look as amazing as it does if they had built it across the river, over by the stadium with all the highrises? Probably not... it stands over there in Xinyi all by itself so that people can marvel at it from any side, any angle.

China is a big place... by land mass alone, it's slightly larger than the US. They already have their NYC and Chicago in Hong Kong and Shanghai. Putting this in one of those would just result in it getting lost and becoming an also-ran. So it's time to give another city a chance. Skylines have to start somewhere.

Now... could they have put it in Tianjin, somewhere near but not to close to Goldin Finance? Probably. Tianjin has a budding collection of talls and supers going on... so it definitely could have helped that out. But hey... were talking the Chinese here... who the hell knows what they've got planned!
