Amazon has submitted its proposed development plans for the second phase of its new Arlington headquarters, revealing a heavy emphasis on sustainability both in construction and design of the three 22-story office towers that will total 2.8 million-square-feet.

In the construction of the property, Amazon is targeting LEED Platinum certification, the highest rank offered by the Green Building Council. To meet this goal, the property will have an electric central heating and cooling system that will run on 100% renewable energy provided by a solar farm in Pittsylvania County, Virginia. The sustainable features will also help Amazon achieve its goal of reaching net-zero by 2040 and Arlington's sustainability plans as well.

The design also supports sustainability and clean living. Working with architecture firm NBBJ, the property features a helix design that incorporates gardens and trees native to the region planted around the spiral of the property—the same design of the firm's Seattle headquarters.
