Part 2: Iconic Taipei 101 Raises The Bar- Now the World's Tallest LEED Platinum Building

Taipei 101, one of the most iconic properties in Asia, was officially recognized on July 28
as a LEED record-setter. In a ceremony whose participants included the chair of the U.S.
Green Building Council, the premier of the Republic of China Taiwan, government officials
of Taiwan and Taipei, and executives of Siemens Building Technologies and Taipei Financial
Center Corporation, the Taipei 101 project was awarded the LEED-EBOM (Existing Building
Operations and Maintenance) Platinum plaque, and lauded as the world's tallest and largest green
building, and the green building with the largest tenant base.

Taipei 101, already one of the globe's pre-eminent skyscrapers, stands an imposing 1667 feet
(508 meters) from base to pinnacle. Completed in 2004, Taipei 101 supplanted Petronas Towers
in Kuala Lumpur, Malaysia (1483 feet, 452 meters), as the world's tallest building, with 101
stories above grade and five underground. While no longer the world's tallest property (that
honor passed in 2010 to Dubai's Burj Khalifa-- 2,717 feet, 828 meters), Taipei 101 has become a
world leader in building sustainability and energy-efficiency, demonstrating that even the largest
multi-tenant buildings can join the elite LEED Platinum club.

Building History. Taipei 101 was designed to be energy-efficient and eco-friendly from the
outset. Upon completion in 2004, the property's double-paned and glazed curtainwalls were
designed to block external heat by 50 percent, and roughly 30 percent of the building's water was
recycled. The building was equipped with a sophisticated Energy Monitoring and Control System
designed and installed by Siemens. Green certification was not sought, however, because LEED
was not well-known in Asia when Taipei 101 was under construction.

When Taipei 101 reached its fifth year of operation, building ownership decided to re-evaluate
the property's energy and environmental performance and seek green certification. LEED was
chosen as the appropriate certification vehicle because of its strong international reputation
and its recognition among Taipei 101's global tenant base, which includes Bank of America,
McKinsey & Company, Boston Consulting Group, KPMG and other leaders in international
business.

LEED Retrofit Focus Areas. The LEED Platinum retrofit of Taipei 101 was led by Harace Lin,
Chairman and President of Taipei Financial Center Corporation, the building's owner, and Cathy
Yang, Vice President of its Tower Division. The retrofit was principally executed by Siemens
Building Technologies, and LEED certification obtained by Steven Leach Group and EcoTech
International.

Key elements of the Taipei 101 retrofit included:

• Conducting an ASHRAE (American Society of Heating, Refrigerating and Air-
Conditioning Employees) Level II energy audit, to evaluate energy performance and
identify areas in which cost-effective improvements could be made.

• Re-calibrating the tower's ventilation and mechanical equipment to enhance
performance, a practice known as retro-commissioning.

• Modifying the operating schedules of the chiller plant which supplies cooling to the
building, so that power could be purchased at off-peak prices.

• Installing temperature and humidity sensors on all floors in order to fine-tune the delivery
of cooled air to tenant spaces, thereby improving occupant comfort and reducing power
use.
