- green building - In 2016, our Desserault office became the first certified 5 star green building, for commercial use, in the Yakima Valley. The certified Built Green® office was constructed in 2015 from recycled and eco-friendly materials, including refurbished metal, energy efficient windows, solar skylights, and zero-voc materials. We are proud to showcase this building as symbol of our core values: environment stewardship, quality, and employee health and happiness. We look forward to modeling future construction after this project. PAGE 36
