KPFF’s Dave Rossi and Nicholas Miley were excited to attend last week’s ribbon cutting event at Sunnyvale City Hall. Designed by SmithGroup, PAE, and KPFF to be the first net-zero and LEED Platinum city hall, the new building raises the bar for sustainability in civic projects and demonstrates the City of Sunnyvale’s commitment to positive change.
Biophilic design elements such as the timber curtain wall, sweeping tree lined terraces and a curving wood-clad central feature stair bring the project to life. A large PV array canopy above the roof provides on-site energy generation and shades the building below.
KPFF reduced structural embodied carbon by specifying high cement replacement mixes including 70% replacement in the mat slab and slab on metal deck. We also designed the seismic system for enhanced resiliency, reducing potential repair costs and materials that would be needed after a major event.
“It’s amazing to see all of the hard work by Hensel Phelps and the design team come together into a beautiful and innovative. I had the chance to talk to some city employees who have moved in and are enjoying their new space – it really made it all feel worth it,” says Nicholas Miley.
