California Department of Transportation (Caltrans) District 5 Office Building - San Luis Obispo, California


Program: 35,000 Office Renovation and Addition
Achievements: LEED-NC Gold Certified
Awards: 2017 Central Coast Green Building Council Green Renovation Honor Award

The project involved a major renovation of and addition to an existing 17,000 SF structure. Built in the 1960s, the space was originally used as a storage building and more recently a small viticulture processing plant, before it was remodeled for the new Caltrans offices.

The project achieved LEED Gold Certification –exceeding the owner’s requirement to attain LEED Silver– through a variety of sustainable construction strategies, including: building and materials reuse, energy-efficient design, low impact development for stormwater management, and reduced indoor and outdoor water use.
