Part 1: Taipei 101- Preparing For A Historic LEED Unveiling

Of course, larger data sets are needed to persuade investors and lenders that green retrofits make good business sense, but Taipei 101 shows that even a capital intensive LEED Platinum retrofit generates near-term savings that can be taken to the bank by property owners and their capital providers. Tomorrow, we'll find out why the ownership of Taipei 101 decided to pursue LEED Platinum certification, and how Siemens, Steven Leach Group and EcoTech achieved their results. Today, Siemens hosted an international group of journalists and management from Siemens' Asia operations to set the stage for event. In attendance were real estate managers and journalists based in Hong Kong, Korea, the United Arab Emirates, Bahrain, Switzerland and the U.S. Together, we cover a wide swath of the globe, both as professionals in the energy-efficient real estate sector and reporters who closely cover commercial real estate and green building trends.

I'd like to share the highlights of today's preparatory discussions because they shed light on the state of the worldwide real estate and green building industries.

Key trends include the following: • While commercial real estate development and construction are influenced significantly by local requirements, general market trends are increasingly global in nature. The professionals with whom I talked today—who hailed from four continents— all stated that their immediate markets declined substantially starting in 2008, and that ground-up construction has been confined primarily to completing projects already in the pipeline. All believe that the bottom of the market has probably been reached, but that real estate activity continues to trend at reduced levels. No one felt that a significant uptick has been realized, although all look forward to better days ahead. What is striking is the uniformity of these conclusions—likely the result of the increasing interconnectedness of global markets, the standardization of financial decision-making and the centralization of capital flows. •  Sustainability is increasingly driving commercial real estate construction and retrofit, particularly for large, Class A properties. Green certification is occurring more frequently worldwide, although the dominant certification systems vary by nation and by region. LEED, the voluntary standard first introduced by the U.S. Green Building Council, is the dominant green building certification system in the U.S, while the Middle East utilizes both LEED and BREEAM (BREEAM is the sustainable certification system created by the British Research Establishment, and has been used widely in parts of the European Union, in the Middle East and in some parts of southeast Asia.) Asian nations, including China, Singapore, Korea and Taiwan, have introduced government-sponsored green building certification systems, which are frequently used alongside LEED or BREEAM. •  As of 2011, building owners and contractors are focusing on energy-efficiency as the key component of sustainability. There is also keen interest in developing the metrics needed to quantify the effectiveness of green building strategies, whether in financial savings or the reduction of carbon emissions. While there is general agreement that the commercial real estate industry wants to 'do the right thing' by the environment, current financial constraints mandate that projects deliver measurable results.

Taipei 101 | Three-time LEED Platinum certified tower and the world’s first building over 500 meters tall

With 101 floors and over 2 million square feet and measuring 1,667 feet (508 meters) tall, TAIPEI 101 is one of the tallest buildings in the world. It has set a worldwide precedent for sustainable skyscraper development, receiving its first LEED Platinum certification in 2011. In 2016, it became the first LEED v4 certified project in the world to achieve 90 points and the world’s first LEED v4 Platinum super tall building. The project received LEED Platinum certification for the third time in 2021, using the latest version, LEED v4.1.

With the implementation of MERV 13 filters and green cleaning for over 10 years, CO2 and TVOC values are extremely low creating a healthy indoor environment.

Low carbon commuting via MRT, buses, bike-sharing and EV cars; 50 energy-saving projects over the past decade for continuous improvements in energy efficiency; the division of waste into 26 categories; a Swedish vertical garbage chute system and 70% waste recycling rate are examples of sustainable strategies put into place.

Structural Engineering of Taipei 101

Taipei 1O1 is a successful skyscraper construction and a bizarre architectural history standing on the grounds of the Xinyi district of Taipei , located in Taiwan. The importance of the tower building is an emblematic expression of commerce, architecture , and sustainability; the structural engineering of construction heralds a commercial picture with its financial services and vibrant shopping mall; apart from this, the skyscraper is acclaimed as the 7th tallest tower in Asia and 10th tallest tower in the world with the height of 508m; moreover, the building has sustainable measures, and it is certified as a LEED Platinum green building.

Architectural features

The architectural model of the building is zoned; at two different levels based on its commercial requirement; the square-shaped complex is the mall building, and the tower structure inhabits the office space. The tower is a series of eight modules with 25 floors in each module that diverge outward from the base to the top; the topmost module is lower in perimeter but rises as a pinnacle that eyespots the city’s visualization; and the form of the building engulf the traditional form of the Chinese Pagoda .

Taipei 1O1 is the first skyscraper built with the concern of sustainability, and to achieve that building has an implementation of various sustainable models, such as; the facade is constructed with double-paned green glass curtain walls. These green glasses are highly reflective in nature and block half of the solar radiation waves resulting in a thermally comfortable environment inside the building.  Apart from this, there are other sustainable aspects found in the energy management and control system of the building that includes controlled illumination through energy-efficient luminaires, custom lighting controls, and the use of smart technology in equipment, for example, low-flow water fixtures.

Structural engineering behind building’s stability

Taipei 1O1 is considered an architectural and engineering marvel, as per the technical innovation installed to sustain the structural stability against the hazardous surroundings susceptible to harsh environments and disaster. The structure is prone to earthquakes and witnessed an earthquake of 7.1 magnitudes during its construction and a category 5 typhoon in the year 2015. The two events derive the importance and requirement of structural strength and flexibility that would be capable of resisting the disasters.

Foundation System

The site of the Taipei 1O1 demands a well-planned foundation system, as reported in the soil investigation, which states that the building site has the constituent of soft soil in the form of clay that is abuted vertically with the colluvial soil and these soils have low load bearing capacity. Apart from this, a layer of soft rock in the form of sandstone lies underneath the depth of 40m to 60m, which imbibes the requirement of a stiff foundation. The site has a matt foundation with bored piles to distribute the load of the superstructure. The tower has a 21 m deep basemen t with the water table at the site 2m below the ground level, uplifting force on the foundation of the building. So the construction of 1.2 m thick and 47 m deep slurry walls supported the excavation and foundation beneath the ground level.

The foundation of the tower has 380 piles of 1.5m diameter and 167 piles inserted beneath the podium. The piles were capped with 3 to 4.7 m concrete raft slabs to transfer the load of columns and walls.

Superstructure Engineering

The structure of the tower is biomimicry of bamboo, light in weight, flexible and strong; the joints in the bamboo are the source of strength replicated in the building in the form of outriggers and belt trusses on every eight floors. The shape of the base module is a truncated pyramid resisting the lateral stiffness as compared to cuboidal blocks; floors are composed of composite steel and concrete of thickness 135 mm. The steel used in 80 percent of construction is of 420 MPa strength while concrete has 70 MPa strength.

Wind and Seismic Load Configuration

Typhoon 1O1 experiences a wind velocity of 156 kmph that impacts the building due to the vortex shedding the alternate crosswinds producing alternate whirlpools that affect the facade. The sharp corner of the building has more impact on wind force hence; the saw-tooth edges of the building reduced the crosswind force on the facade.

The lateral load from earthquakes was another concern that required the building to have a strong core and perimeter columns. The floor plan of the tower has 16 box columns arranged in four lines which are braced by frames and cased in concrete walls of strength 69 MPa till the 62nd level. The perimeter core has eight super columns 3m long and 2.4m wide, steel boxed with the help of 50 to 80 mm thick welded steel plates and filled with concrete, and are constructed up to the 90th level to resist the overturning of the tower. Shear studs bind the steel and the concrete together. The structure core allows the building to stand against 0.5-g ground acceleration.

Mass Damper

The area between the 86th and 92nd floor of the building has a massive pendulum of 726 tonnes and 6m diameter known as a Tuned mass damper, TMD installed to counter the wind force reduces the sway of the building in typhoons also, and the damper enhances the inhabitant’s comfort in strong winds. The damper acts as shock absorber released from building motion that energy from the building due to wind oscillations and reduces building movements .

Taipei 101 – Structural Engineering Explained

• Post published: June 12, 2021
• Post category: Case Studies
• Opens in a new window

In this post we will be learning about structural engineering behind Taipei 101.

Typhoons, earthquakes, difficult soil conditions, site present near an active fault line, water table just below the surface, all applied to a structure more than half a kilometer tall. Taipei 101 is an engineering and architectural marvel. The structure witnessed an earthquake of magnitude 7.1 during the construction and recently, a category 5 typhoon in the year 2015. Hence the building must be flexible enough to resist an earthquake and stiff enough to resist a typhoon.

Taipei 101 is located in Taipei, which is the capital of Taiwan, located in east Asia. It is currently the 10th tallest building in the world at 508 meters (1667 ft.) and was the tallest building in the world from 2004 to 2010. 

The project consisted of a 5 storied retail mall and hundred and one storied office tower. If we see the site in plan above, the yellow portion is for the tower and blue for the retail mall.

80% of steel used in the building is of 420MPa strength or 60ksi while concrete used is of 70MPa strength or 10,000 psi.

Now let us look at the foundation system used for the building. The above image shows building section with ground level and basements for podium and tower.

Soft soil in the form of clay, and stiff colluvial soil is present just below the site of Taipei 101, which has low load bearing capacity. Soft rock in the form of sandstone is present beneath 40 to 60 meters (130 to 200 feet), hence it required mat foundation with bored piles.

The tower required a 21 meter (69 feet) deep basement. Water table at site is 2 meters (6.5 feet) below ground which would create huge uplift forces on the foundation of the building. Hence slurry walls were constructed to lay the foundation below the tower. Slurry walls are deep walls constructed on site to prevent water and soil caving in while construction of foundation and excavation.

These walls surround both the tower and the podium and are 1.2 meters (4 feet) thick and upto 47 meters (154 feet) below ground. 

Main foundation of the tower consists of 380 piles of 1.5 meter diameter and 167 piles for podium area. They were spaced 4 meters (13 feet) apart in staggered rows for tower portion. A concrete raft of thickness 3 to 4.7 meters capped the piles and transferred loads from columns and walls above. 

Use of steel in the superstructure minimised the building weight which reduced the cost of foundation. 

Super Structure

Now let us understand the super structure of the tower.

The building is 508m above ground and resembles ancient pagodas. It takes inspiration from Bamboo which is flexible and light, yet strong. The bamboo has joints at intermediate locations which are mimicked by the building in the form of outriggers and belt trusses at every 8 floors. We will learn about outriggers and belt trusses in the later part of the post. This separates the building into 8 identical modules. 

At the top of 8th module sits a 9th module which has a smaller footprint. This module  supports a spire and contains equipment and an observation deck.

Below the 8 repetitive modules, a 25 story base, shaped as a truncated pyramid is present. This base provides an improved overturning resistance and lateral stiffness compared to a straight block.

The story height of each floor is 4.2 meters and retail floors below are 6.3 meters. The floor is composite steel and concrete, typically 135mm thick (5.3 inch).

Wind and Seismic Forces

Now let us know about the wind and seismic forces acting on the building and ways the building resists them.

Taipei 101 is present in a high typhoon zone which experiences winds of 156 kilometres per hour (97 mph) with 100-year return period. The building is impacted by alternating crosswind forces due to vortex shedding which means wind passing the building separates from the sides producing alternating whirlpools. Large forces can result when the time period of the building matches with the period of vortex formation. These winds can also damage the façade and partitions.

Wind tunnel tests were conducted which showed that sharp corners of a square building produced large cross wind forces. Hence ‘saw tooth’ or ‘double notch’ corners were provided which reduced the wind forces by up to 40%. 

For resisting the lateral load from earthquakes and wind a building needs a strong core and perimeter columns.

Typical Plans

Let us see a typical plan of the building above level 26. The building has a square core made up of 16 box columns in four lines, which are generally fully braced by moment frames between floors. The braced core is encased in concrete walls from foundation to the 8th level.  The core box columns were filled with concrete of strength 69MPa till level 62. 

The building has 8 ‘super columns’ or ‘mega columns’ which are steel boxes filled with high strength concrete. They are present on the perimeter of the building, 2 on each face. These super columns were built up to level 90 of the tower. They were filled with concrete of strength 69MPa from bottom of basement till level 62. 

These columns control drift as large portions of drift is created at lower stories due to overturning rotations. The interstory drift and overall lateral motion were limited to Height by 200.

Super Columns were built from 50 to 80mm thick steel plates with welded splices. Highest dimensions of the column are at 3 meters by 2.4 meters and vary along the height of the building. 

Internal cross ties resist bulging of the column. Shear studs link concrete and steel together and rebars strengthened the concrete. 

The building was designed to be stiff for resisting the wind forces first and then checked for seismic ductility and seismic strength. The steel framing used in the building is Special moment resisting frame also known as SMRF. Ductility was provided by using reduced beam section or ‘dogbone’ detail. Steel moment frames along each sloping face of the building works in parallel with the braced core and outriggers to counter seismic forces. The building is engineered to stay up under a 0.5-g ground acceleration.

Now let us see the typical plan of the tower below level 26.

Below this level, super columns slope with the building’s profile as shown in the section. Two columns of size 2 meters by 1.2 meters are added toward the center of each façade, while each corner is supported by an additional 1.4 meters square, sloping box column.

Main floor girders shown in yellow connect each super column through moment connections with a core corner column, along the same line. Rest of the floor beams are shown in green in these typical plans below 26th level and above 26th level which support the composite floor. We can also see locations of stairs and shaft openings for elevators and utility services.

Outriggers and belt trusses

Now let us talk about Outriggers and belt trusses used in the building. 

Outriggers are as the name suggests are extra structural members to resist the overturning forces. Boats and cranes as shown in the picture use outriggers to counter the overturning forces.

In structures, outriggers basically tie two structural systems together, which are core and perimeter systems. When subjected to lateral loads, the column restrained outriggers resist the rotation of the core, causing the lateral deflections and moments in the core to be smaller than the system without the outriggers. The external moment is now resisted not by bending of the core alone, but also by the axial tension and compression of the exterior columns connected to the outriggers. 

Belt truss as the name suggests, forms a belt around the building connecting perimeter columns. Belt trusses are often provided to distribute the tensile and compressive forces to a large number of exterior frame columns.

In Taipei 101, belt trusses below level 27 are two stories deep at levels 9, 19 and 27. For upper floors, the belt trusses are single story deep, every 8 floors tying main perimeter columns by cross bracing. These belt trusses gather and transfer perimeter weight to two super columns on each face. 

Outriggers in Taipei 101 were formed by vertically bracing two adjacent floor girders through occupied space, every 8 floors, just like bamboo joints. Two minor outriggers connect the core’s central columns with sloping I-shaped columns. This floor was dedicated to storage and mechanical equipment as open space is occupied by trusses. 

Mass Damper

Now let us talk about the Mass Damper used in the building. At the top of the building between 86th and 92nd floors, is a huge pendulum which is called a Tuned mass damper or just TMD. This pendulum counters the wind force and reduces sway of the building in the typhoons. The occupant comfort is also increased during strong winds due to the damper.

This damper uses building motion to push and pull giant shock absorbers to convert motion to heat by forcing fluid through small internal openings. When the building sways the mass will tend to move in the opposite direction. This removed energy from the building due to wind oscillations and reduced movement.

The pendulum is of 726 tons and 6 meters diameter. It is built up from stacked steel plates and weight is equal to 0.24% of the total building weight. Recently a typhoon of category 5 caused the damper to sway a record 100 centimetres or 39 inches. 

Two additional 7-tonne dampers control the oscillations for the 60-m-tall pinnacle rising from the hundred and one level. In the event of an earthquake the sudden shock locks the mass for safety during seismic events. 

Taipei 101 is a very special building in the world of engineering and architecture. Its ability to take on every challenge thrown by nature is remarkable and it will remain an icon for years to come.

Taipei 101, the modern structure is formerly known as the Taipei World Financial Center. It is a skyscraper designed by C.Y. Lee and C.P. Wang in Xinyi, Taipei, Taiwan. This building was recognized as the world’s tallest from its opening in 2004 until the 2009 completion of the Burj Khalifa in Dubai. The height of the building is 1667 ft (508 meters) from the ground to the tip of the spire. The building consists of 101 floors above the ground and 5 floors below the ground. At the time of its official opening in October 2004, it was the world’s tallest building, having surpassed the Petronas Twin Towers in Kuala Lumpur, Malaysia.

The is inspired and derived from traditional Chinese architecture, resembling the shape of a pagoda. The sectioned tower is also inspired by the bamboo plant which denotes strength, resilience, and elegance. The tower design specifications are based on the number 8. It is a lucky number in traditional Chinese culture. This design features 8 upward–flaring sections and is supported by 8 super columns.

The lowest floors that lay above the ground of Taipei 101 houses a luxury atrium shopping mall. Most of the floors above the mall are dedicated to office space. The public observatories are situated on floors from 88 to 91. There is an indoor observatory on 89 and an outdoor observatory on 91. At a height of 1,285 feet (392.8 meters), the outdoor observatory was the highest in the world at the time of completion. Another indoor observatory, not open to the public, is on the top (101st) floor and is 1,437 feet (438 meters) high.

The construction of Taipei 101 started in 1999. The structure, out in 2003, and the work completes by 2004. The largest section of the building, between the base and the spire, consists of eight modules, or groupings, of eight stories each (eight being an auspicious number in Chinese numerology). The building also expresses its distinctive Chinese character as its resemblance to a stalk of bamboo or an elongated pagoda.

• It has 380 piles with 3-inch concrete slab.
• The Mega columns are 8 cm thick steel and 10,000 psi concrete infill to provide for overturning.
• The Walls in the building are 5 to 7-degree slope.
• 106,000 tons of steel, grade 60- 25% stronger.
• There were 6 cranes on site – steel placement.
• Electrical & Mechanical
• Curtain wall placement

Like most modern tall buildings, Taipei also has a cool feature which is also one of its unique aspects, a visible tuned mass damper. At 5.5 meters, or 18 feet, in diameter, and 660 metric tons, or 728 US tons, it’s the largest of its kind in the world. This is an effective counterweight of a pendulum that attaches but not rigidly to the building. When the building sways back the other way, the mass damper, now just catching up to where the building was, is now a drag on the building moving the other way. Mass dampers, usually mounted high in the building, do an amazing job stabilizing tall skinny buildings, especially those in areas known for typhoon winds and earthquakes. Since Taiwan has an active seismic zone, hence the building’s strong structure.

The building is a pile through clay-rich soil to bedrock 40 – 60 m below. Also, the plies are topped by a foundation slab which is 3m thick at the edges and up to 5m thick under the largest of columns. There are a total of 380 1.5m dia. Taipei 101 is one of the most stable buildings ever.

Taipei 101, Taiwan—Skyscraper Case Studies: Vertical City (Series 2)

Description.

Taiwan, China’s renegade province, wanted to make the world sit up and notice it—so it built the planet’s tallest skyscraper, Taipei 101, in its capital city. An architectural meeting of East meets West, Taiwan’s biggest global advertising board and symbol of achievement was a defiant gesture towards its neighboring superpower, and a calculated quest for Taiwanese commercial attention proving that in modern times, the super-tall building is more than just the corporation HQ of the past. But does having the tag of the tallest guarantee success? And why isn’t there a host of other skyscrapers in this city like its competitor over the water, Shanghai? Presented by Matt Berman.
