Amazon has completed construction of the first two buildings of its second headquarters, located in Arlington, Va. The all-electric structures, featuring low carbon concrete and mass timber, help further the company’s commitment to achieving net zero carbon emissions by 2040 and 100% renewable energy consumption by 2030.
Designed by ZGF Architects, the two 22-story buildings—comprising 2.1 million sf of space and 50,000 sf of retail space—are on track to become the largest LEED v4 Platinum buildings in the U.S., according to a statement from ZGF.
By using low-carbon concrete mixes and CarbonCure technology, the project achieved a 20% reduction in the concrete structures’ carbon footprint, compared to the industry baseline. ZGF incentivized trades to experiment with mixes and reduce greenhouse gas emissions. The firm’s open-source LCA calculator enabled construction partners to assess proposed concrete mixes and measure their impact.
The buildings capture and reuse rainwater, shower water, and HVAC condensation—helping to achieve 50% water savings below building code and recycle 7.5 million gallons a year. And more than four-fifths of all construction waste materials—including concrete, drywall, metals, wood, cardboard, and plastic—were diverted from landfills. This prevented over 17,000 tons of material from entering landfills.
Amazon funded the renovation and expansion of the adjacent Met Park—turning an underused green area into a public park. In addition to the central green, the 2.5-acre park features a children’s playground with a jungle gym, small and large dog parks, and a community garden. Art pieces have been placed along the park’s forest walk.
The buildings feature 19 rooftop terraces, eight of which can be occupied. On a farm terrace, Amazon employees can volunteer to grow herbs and vegetables that will be donated to community organizations. The two towers also have more than 3,000 operable windows.
On the Building Team:
Owner: Amazon
Developer: JBG Smith
Design architect and architect of record: ZGF Architects
