This past August American AgCredit celebrated 100 years of serving farmers throughout the United States. The event was marked with ribbon cutting at their new headquarters and Agriculture Hub complex in Santa Rosa. Congressman Mike Thompson and Congressman Jared Huffman attended and delivered a message from President Obama, who recognized the significance of American AgCredit's century-long contribution to agriculture.
Organic Curves and Green Construction
Designed by TLCD Architecture and built by Jim Murphy and Associates (JMA), the long sweeping curves posed a challenge to the structural team.
“Enveloping the curved floor plans into the structural design and accounting for the interaction between the two buildings at the connecting bridges was far more involved than four separate buildings," said Kevin Zucco, ZFA Executive Principal. "However, the architectural design was extremely important to American AgCredit, both in form and function." The ZFA team explored different options in analysis and construction working closely with the design team and contractor to implement a structural plan that provided future flexibility to the client. The two buildings were connected by three pedestrian bridges on the second and third floors.
Recycled and local materials and agriculturally prominent details were used extensively throughout the buildings. The entry way has a rammed earth wall, sourced from several AgCredit sites nationwide, and the primary walkway displays a wall built of wine barrel staves. Artwork was sourced from 29 artists, including a two-and-a-half story tall mural of Italian cow hide.
Keeping with green construction principals, a reddish-brown zinc panel semi-transparent cladding system was positioned vertically along the curved exterior to provide shading from the sun, naturally reducing energy costs. To make the building sustainable and deliver flexibility into the future, special steel moment frames were used as the lateral force resisting system. Raised floors with under-floor air ducts and cabling provide interior circulation of exterior fresh air. This unique building also features a metal roof deck with a concrete walking portion and spacious courtyard that is an organic shape to promote a healthy work environment.
The American AgCredit Headquarters is a state-of-the-art building that will support future growth and American agriculture.
