Designed by the international design firm Gensler and owned by the Shanghai Municipal Government, it is the tallest of the world's first triple-adjacent supertall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center.

A repetitive slip-forming process was used to construct the tower's core floor by floor.

The tower's floor plate has an "efficiency rate of only 50 per cent on some floors, compared with 70 per cent for a typical [skyscraper]", as the tower's "much-talked-about outer skin, which is ideal for allowing in natural light and cuts down on air-conditioning costs... means much of the floor space can’t be used."{{Cite web |last=Yan |first=Sophia |date=2017-06-02 |title=China's tallest skyscraper is facing rental woes, reflecting wider issues in the market |url=https://finance.yahoo.com/news/china-apos-tallest-skyscraper-facing-040046421.html |access-date=2024-04-24 |website=Yahoo Finance |language=en-US}}

In July 2020, major water leaks broke out from the 9th to 60th floors of the tower, which damaged a number of office equipment and electronics.

Being the second-tallest building in the world from since its completion in 2015, the Shanghai lost its title in 2021, when the Merdeka 118 surpassed it. The tower surpassed the Shanghai Tower by slightly over 49 meters (160 feet).

In December 2022, it was reported that, following its initial pre-pandemic tenancy issues, the tower had reached office space occupancy rates of 80% and commercial space occupancy rates of 98%. The tower management disclosed that 41% of its leased space were to foreign company tenants, which included JPMorgan, CNG Paribas and Allianz, and 30% were to Fortune 500 companies.{{Cite web |title=Shanghai Tower rentals reflect confidence in country |url=https://www.thestar.com.my/business/business-news/2022/12/28/shanghai-tower-rentals-reflect-confidence-in-country |access-date=2024-04-24 |website=The Star |date=28 December 2022 |language=en}} Current tenants of the tower also include Alibaba, Intesa Sanpaolo and AllBright Law Offices.{{Cite web |title=“中国第一高楼”引发美国人关注,却是因为... - 21财经 |trans-title="China's Tallest Building" Attracts Attention from Americans, But It's Because of... – 21st Century Business Herald |url=http://m.21jingji.com/article/20170610/herald/796063812bd1ac411e3e30eaf4f0ed9c.html |access-date=2025-04-13 |website=m.21jingji.com}}

Design

File:Shanghai tower 2021 summer.jpg

The Shanghai Tower was designed by the American architectural firm Gensler, with Shanghainese architect Jun Xia leading the design team.{{cite web|first=Ben|last=Ikenson|date=July 2013|url=http://www.metropolismag.com/June-2013/Genslers-Secret-Sauce/|title=Gensler's Secret Sauce|work=Metropolis Magazine|access-date=3 November 2013}}{{cite web|url=http://www.ucdenver.edu/about/WhoWeAre/spotlight/alumni/Pages/Jun-Xia.aspx|title=Taking Education to New Heights: Alum Designs Tallest Building in China|publisher=University of Colorado Alumni Spotlight|year=2013|access-date=3 November 2013}}

The tower takes the form of nine cylindrical buildings stacked atop each other that total 128 floors, all enclosed by the inner layer of the glass facade. Between that and the outer layer, which twists as it rises, nine indoor zones provide public space for visitors.{{cite web|title=Tallest Chinese building features indoor gardens|url=http://www.shanghaidaily.com/sp/article/2008/200807/20080724/article_367915.htm|publisher=Shanghai Daily|date=24 July 2008|access-date=9 August 2008|archive-url=https://web.archive.org/web/20081216075634/http://www.shanghaidaily.com/sp/article/2008/200807/20080724/article_367915.htm|archive-date=16 December 2008}} Each of these nine areas has its own atrium, featuring gardens, cafés, restaurants and retail space, and providing panoramic views of the city.{{cite web|first=Woo|last=Seung-hyun|year=2010|url=http://gb.zinio.com/reader.jsp?o=int&pub=500430369&prev=sub&offer=500216011|title=Integrated design of technology and creative imagination on supertall building|pages=32–33|work=Space Magazine|access-date=15 January 2012|archive-date=17 February 2017|archive-url=https://web.archive.org/web/20170217143521/http://gb.zinio.com/reader.jsp?o=int&pub=500430369&prev=sub&offer=500216011|url-status=dead}}

Both layers of the façade are transparent, and retail and event spaces are provided at the tower's base. The transparent façade is a unique design feature, because most buildings have only a single façade using highly reflective glass to reduce heat absorption, but the Shanghai Tower's double layer of glass eliminates the need for either layer to be opaqued. The tower can accommodate as many as 16,000 people daily.

The Shanghai Tower joins the Jin Mao Tower and SWFC to form the world's first adjacent grouping of three supertall buildings. Its 258-room hotel, the J Hotel Shanghai Tower, located between the 84th and 110th floors, is operated by Jin Jiang International Hotels, and is the highest hotel in the world.{{cite web|url=http://www.4hoteliers.com/4hots_nshw.php?mwi=8111 |title=Shanghai Tower J Hotel on course to set the world record|publisher=4Hoteliers.com|date=20 December 2010|access-date=15 January 2012}} The tower will also incorporate a museum.{{cite web|url=http://en.yibada.com/news/shanghai-lady-gets-a-new-home-at-the-shanghai-tower-8813|title='Shanghai Lady' Gets a New Home at the Shanghai Tower|publisher=YIBADA News|date=22 December 2014|access-date=17 January 2015|archive-date=27 December 2014|archive-url=https://web.archive.org/web/20141227221941/http://en.yibada.com/news/shanghai-lady-gets-a-new-home-at-the-shanghai-tower-8813|url-status=dead}} The tower's sub-levels provide parking spaces for 1,800 vehicles.

=Vertical transportation system=

The vertical transportation system of Shanghai Tower was designed by an American consultant, Edgett Williams Consulting Group, with principal Steve Edgett as a primary consultant. Working closely with Gensler's design and technical teams to create a highly efficient core, Edgett created an elevator system in which office floors are served via 4 sky lobbies each served by double-deck shuttle elevators. Access to the hotel is through a 5th sky lobby at levels 101/102. Each 2-level sky lobby serves as a community center for that zone of the building, with such amenities as food and beverage and conference rooms. Local zones are served by single-deck elevators throughout the tower, and the observation deck at the top of the tower is served by three ultra-high-speed shuttle elevators that travel at {{convert|18|m/s|mph|sp=us}}, the highest speed yet employed for commercial building use. These three shuttle elevators are supplemented by three fireman's elevators which will significantly increase the visitor throughput to the observation deck at peak usage periods. In the event of a fire or other emergency, the building's shuttle elevators are designed to evacuate occupants from specially-designed refuge floors located at regular intervals throughout the height of the tower.

In September 2011, Mitsubishi Electric announced that it had won a bid to construct the Shanghai Tower's elevator system. Mitsubishi supplied all of the tower's 149 elevators, including three high-speed models capable of traveling {{convert|1080|m|ft|sp=us}} per minute ({{convert|64.8|km|mi|sp=us}} per hour).{{Cite web |last=Mills |first=Kelly-Ann |date=2016-03-14 |title=World's second tallest skyscraper's lift opens travelling 18m a second |url=https://www.mirror.co.uk/news/world-news/shanghai-tower-worlds-second-tallest-7553380 |access-date=2025-04-13 |website=Daily Mirror |language=en}} When they were installed (2014), they were the world's fastest single-deck elevators ({{convert|18|m/s|mph|sp=us}}) and double-deck elevators ({{convert|10|m/s|mph|sp=us}}), respectively.{{Cite news |last=Koh |first=Yoree |date=2011-09-28 |title=World's Fastest Elevator: In China, but Made in Japan |url=https://www.wsj.com/articles/BL-CJB-14407 |access-date=2025-04-13 |work=Wall Street Journal |language=en-US |issn=0099-9660}} A 10 May 2016 Mitsubishi press release stated that one of the three installed shuttle elevators traveled at 1230 meters/minute – the equivalent of {{convert|73.8|km/h|mph|0|sp=us}}, the highest speed ever attained by a passenger elevator installed in a functioning building.{{cite web|url=http://www.businesswire.com/news/home/20160509005599/en/Mitsubishi-Electric-Improves-Speed-Worlds-Fastest-Elevators|title=Mitsubishi Electric Improves Speed of World's Fastest Elevators to 1,230 Meters per Minute|date=10 May 2016|work=Business Wire}} The building also broke the record for the world's furthest-traveling single elevator, at {{convert|578.5|m|sp=us}}, surpassing the record held by the Burj Khalifa.{{cite web|url=http://www.mitsubishielectric.com/news/2011/0928.html|title=Mitsubishi Electric to Install World's Fastest Elevators in Shanghai Tower|publisher=Mitsubishi Electric|date=28 September 2011|access-date=15 April 2013|archive-date=15 July 2017|archive-url=https://web.archive.org/web/20170715050223/http://www.mitsubishielectric.com/news/2011/0928.html|url-status=dead}} The Shanghai Tower's tuned mass damper, designed to limit swaying at the top of the structure, was the world's largest at the time of its installation.{{cite news|last1=Hefferman|first1=Tim|title=The 121-Story Tower That Never Sways|url=http://www.popularmechanics.com/technology/infrastructure/a14564/the-121-story-tower-that-never-sways/|access-date=18 March 2015|work=Popular Mechanics|date=18 March 2015}}

=Sustainability=

The Shanghai Tower comprises numerous green architecture components; its owners received certifications from the China Green Building Committee and the U.S. Green Building Council for the building's sustainable design.{{cite web|url=http://bulletin.pbworld.com/volumes/2014_01/sustainability.aspx|title=The Shanghai Tower: One of World's Most Sustainable Skyscrapers|publisher=Parsons Brinckerhoff|date=January 2014|access-date=20 January 2015|archive-date=28 March 2015|archive-url=https://web.archive.org/web/20150328101110/http://bulletin.pbworld.com/volumes/2014_01/sustainability.aspx|url-status=dead}} In 2013, a Gensler spokesman recounted the tower as "the greenest super high-rise building on Earth at this point in time". The building is designed to catch rainwater for internal use, and to reuse a portion of its wastewater.

The design of the tower's glass façade, which completes a 120° twist as it rises, is intended to reduce wind loads on the building by 24%. This reduced the amount of construction materials needed; the Shanghai Tower used 25% less structural steel than a conventional design of a similar height.{{cite web|url=http://www.matternetwork.com/2010/3/shanghai-tower-beginnings-green-revolution.cfm|date=25 March 2010|author=CleanTechies|title=The Shanghai Tower: The Beginnings of a Green Revolution in China|access-date=19 August 2011|archive-date=3 July 2011|archive-url=https://web.archive.org/web/20110703152505/http://www.matternetwork.com/2010/3/shanghai-tower-beginnings-green-revolution.cfm|url-status=dead}} As a result, the building's constructors saved an estimated US$58 million in material costs. Construction practices were also sustainable. Though the majority of the tower's energy will be provided by conventional power systems, 270 vertical-axis wind turbines located in the facade and near the top of the tower are capable of generating up to 350,000 kWh of supplementary electricity per year,{{Cite news |last=Turk |first=Gregory |date=2017-12-11 |title=U Wang Young |url=https://uwangyoung.org/ |access-date=2017-12-19 |work=}}{{cite news|url=http://www.cnngo.com/shanghai/life/shanghai-tower-shanghais-thermos-flask-sky-713890|date=8 February 2011|author=Beaton, Jessica|title=Shanghai Tower: A 'thermos flask' to the sky|publisher=CNN|access-date=19 August 2011|archive-date=24 August 2011|archive-url=https://web.archive.org/web/20110824162754/http://www.cnngo.com/shanghai/life/shanghai-tower-shanghais-thermos-flask-sky-713890|url-status=dead}} and are expected to provide 10% of the building's electrical needs. The double-layered insulating glass façade was designed to reduce the need for indoor air conditioning, and is composed of an advanced reinforced glass with a high tolerance for temperature variations.{{Cite web |title=Shanghai Daily {{!}} 上海日报 -- English Window to China News |url=http://www.shanghaidaily.com/nsp/Metro/2012/08/03/Glass+walls+technological+first+for+new+tallest+tower/ |archive-url=http://web.archive.org/web/20131029204807/http://www.shanghaidaily.com/nsp/Metro/2012/08/03/Glass%2Bwalls%2Btechnological%2Bfirst%2Bfor%2Bnew%2Btallest%2Btower/ |archive-date=2013-10-29 |access-date=2025-04-13 |website=www.shanghaidaily.com}} In addition, the building's heating and cooling systems use geothermal energy sources.{{cite web|url=http://www.prc-magazine.com/shanghai-tower-future-living-today/|title=Shanghai Tower – future living today|work=Pacific Rim Construction Magazine|date=27 February 2013|access-date=9 March 2013}} Furthermore, rain and waste water are recycled to flush toilets and irrigate the tower's green spaces.
