U.S. Green Building Council (USGBC) leaders travelled to Taipei last week to bestow a great honor on Taipei 101, awarding the highest standards under the USGBC’s Leadership in Energy and Environmental Design (LEED) and the criteria set for Existing Buildings: Operations and Maintenance (EBOM). BAC is proud to be a part of this occasion with 51 tanks of BAC’s Ice Thermal Storage as an integral part of Taipei 101’s cooling system.

The 101-story skyscraper has more than 2.5 million square feet and stands at a striking 1,667 feet tall.* From its completion in 2004 until the middle of 2010, it stood at the tallest building in the world.** The building is designed to use less energy and water while providing better indoor air quality than a traditionally built skyscraper.

Taipei 101 is the tallest existing building to attain LEED-EBOM certification at the platinum level, the highest level possible. At 1,667 feet tall, cooling the building in an environmentally conscious way was a challenge. BAC’s Ice Thermal Storage tanks (36,450 ton-hours) were selected because of their ability to provide extremely low fluid temperatures – in this case 2°C (35.6°F). Such low supply temperatures allowed economical selection of pressure isolation heat exchangers on the 42nd and 74th floors, all while using the primary energy push at night, when chillers are more efficient and when it was taking crucial energy consumption off of the main daytime energy grid. The ice is then discharged during the day, providing cooling to the skyscraper and neighboring complex buildings.

With the new energy initiatives, Taipei 101 reportedly uses 30% less energy than other buildings of its relative size. That’s amazing! Kudos to Taipei 101! Want to read more? Here’s an article that was recently put on TIME’s webpage and more here from the Taipei Times.

*The Empire State Building is only 1,250 feet tall.

**The tallest building in the world is now the Burj Khalifa in Dubai.
