The new District Energy System (DES) at Marine Gateway provides the 820,000 SF complex with central energy. The system also includes the potential to expand to adjacent sites. The system features a closed loop geothermal system which provides up to 70% of the complexes heat. The self contained DES also utilizes heat pumps and low temperatures, to heat water to share energy between different occupants in the building, thereby increasing energy efficiency. The project has also received a LEED Gold recognition.
