Seaport World Trade Center East and West have been awarded LEED Silver certification, making the two Class A towers among only six commercial office buildings in the city to receive such designation, according to a statement.

Seaport World Trade Center East and West total more than 1 million square feet and are Pembroke Real Estate properties, managed by CB Richard Ellis.

"We are very pleased to be recognized for our sustainable and energy efficient efforts at two of our prime assets," said Edward C. Johnson IV, senior vice president, North America for Pembroke Real Estate. "Pembroke and CBRE share an important commitment to delivering and managing properties in a sustainable and environmentally conscious manner."

The team implemented building-wide energy audits, installed lighting retrofits in common areas, rebalanced main air handlers and organized semi-annual HVAC unit tune-ups. To conserve water, dual-flush handles were installed on toilets in all restrooms.

The properties’ sustainability programs have saved roughly 420,000 kilowatt hours of energy, 170 tons of CO2 emissions and approximately 1.4 million gallons of potable water. An additional 270 tons of waste has been diverted from landfills. The entire sustainability program has an expected payback period of approximately 2.4 years.
