GHT Limited serves as the Base Building MEP engineer for Metropolitan Park, the first phase of Amazon’s HQ2 development in Arlington, Virginia. Amazon’s Metropolitan Park campus includes the development of two new buildings, comprised of 2.2 million square feet of sustainable office space, as well as a 4-story underground parking garage.
The campus’ mechanical system utilized energy modeling technology to optimize system efficiency based on the building’s projected load profile. The HVAC system utilizes DOAS, a high-performance HVAC system that maximizes building energy efficiency and usable square footage. The MEP infrastructure further includes greywater and rainwater recycling systems, heat exchange with the permanent foundation dewatering systems, domestic water heating utilizing waste heat from the building, and radiant floor heating. The LEED Platinum buildings will be powered by 100% off-site renewable energy, and on-site strategies will help minimize energy and water use.
GHT spearheaded the carbon + energy focus in the decision-making process for this development at Metropolitan Park, which will involve both energy use intensity (EUI) and life cycle carbon tracking.
