Citi Tower stands out in sustainability efforts

Citi Tower in Hong Kong is the latest Citi-owned building to have been awarded LEED (Leadership in Energy and Environmental Design) platinum certification by the U.S. Green Building Council.

LEED is the highest internationally-recognized rating a building can earn from the authoritative certification body in green building practices.

Citi Tower is on the waterfront of Kwun Tong, Hong Kong. The project, which comprises 18 floors of approximately 301,500 square feet of office space is home to more than 3,000 Citi staff, reports Asia One

Citi has approximately 12,000 owned and leased facilities worldwide. As part of the company’s Sustainable Progress Strategy, the bank made a commitment to obtain LEED certification for 33 percent of its global real estate portfolio by 2020.

There are currently more than 200 LEED-certified Citi facilities globally, which accounts for 20 percent of Citi's real estate portfolio.  

Following the LEED certification assessment, Citi Tower was awarded points by the U.S. Green Building Council for the following environmental accomplishments:

  • 98 percent of the building's lighting is managed by occupancy sensors
  • 53 percent of lighting is managed with daylight controls
  • 95 percent of equipment and appliances is Energy Star-qualified
  • 75 percent of the construction waste was diverted from landfill
  • 25 percent of light power density (LPD) reduction was achieved with no compromise to Citi's lux level requirements by including wattage saving from the digital addressable lighting interface (DALI) lighting system with settings-based space usage during the commissioning stage
  • HVAC systems installed are in line with the efficiency requirements outlined in the Advanced Buildings Core Performance Guide.
  • Paints, adhesives and sealants were vetted for VOC compliance prior to approval for use on the site.

In October 2016, Citi Tower was approved for WELL silver precertification by the International WELL Building Institute. WELL is a performance-based system for measuring, certifying, and monitoring features of the built environment that impact human health and well being, including air and water quality, nourishment, light, fitness, comfort and mind.
