In 2015, the American Geophysical Union (AGU) identified the need for a major headquarters renovation and systems had reached the end of their useful life. AGU sought to communicate its dedication to scientific advancement and reduce the facility’s carbon footprint, while actively engaging and educating the public. The result is Washington, DC’s first-ever net zero office renovation – a 62,000-SF landmark that reflects AGU’s mission and serves as a reminder of the built environment’s impact on the planet.

Being in a historic urban district and the site’s limited footprint, achieving AGU’s net zero energy goals proved highly complicated and involved close coordination across team members from inception. The final product combines a custom mix of ten core sustainable solutions addressing four goals – reduce, reclaim, absorb, and generate – while delivering a modern workplace that supports employees, AGU’s members, and the community.

Hear about the highly collaborative and complex process behind transforming an aging building in a major U.S. city to achieve this monumental feat.
