It’s a common saying that size doesn’t matter, but nobody told the people who built the Taipei 101 tower that. The 1,666 foot tall building has just become the world’s tallest green building by achieving LEED Platinum certification in the Existing Building Operation and Maintenance category from the U.S. Green Building Council. Not only is this now the tallest building to receive LEED certification, it is also the largest scale building with a total area of 1.6 million square feet and the green building with the most tenants at 90.
