Taiwan's Taipei 101 has been officially named as the world's tallest green building by the US Green Building Council.
After a wealth of investment and development over the last two years, the structure has been accredited with a Platinum Level Certification for Leadership in Energy and Environmental Design – Existing Building Operation and Maintenance.
Green conversion first began in November 2009, with an announcement from management to pursue the internationally recognised rating.
The process involved more than 100 individual improvement projects focusing on areas such as waste reduction, energy and water efficiency, all whilst maintaining expected comfort levels concerning heating and cooling.
Air quality is a key factor in attaining the accreditation, with a highly-sophisticated air-conditioning and filtering system managing the levels of carbon dioxide in the atmosphere.
The building – second in height only to Dubai's Burj Khalifa – first opened in 2004, reaching a height of 509.2 metres.
Achieving a green friendly rating has been no easy task, with the building covering roughly 1.6 million square feet.
More than 10,000 tenants currently reside in the building and management have implemented a number of education programs designed to raise awareness of eco-friendly practices for its community.
