A 40-year-old, concrete tilt-up racquetball facility in Sunnyvale has been transformed into a two-story, net-zero-energy office building.
The $7-million core-and-shell project supports the state’s initiative for all new commercial construction to be net-zero energy by 2030. Designers incorporated green strategies such as skylights, photovoltaics, passive ventilation, LED lighting and control systems to minimize energy use and optimize onsite power generation. A real-time dashboard measures energy usage and efficiency.
The mezzanine features a two-story daylit atrium while energy-saving windows change their tint, responding to the sun’s movements, weather patterns, building design and user preference. A concrete shear wall was placed at the building’s core to support a 30-ft living-plant wall.
