David & Lucile Packard Foundation Headquarters, Los Altos, California

The David & Lucile Packard Foundation headquarters isn’t just a beautiful example of modern design, it is a leader in energy efficiency, known for being the largest net-zero energy certified building in the world. Part of that efficiency comes from its effective use of daylight, as well as the 900 photovoltaic panels installed on its roof.

But the building's sustainability doesn’t end with energy efficiency. The complex is made up of 95 percent recycled materials from deconstructed buildings and is equipped with a rainwater collection system that can store 20,000 gallons of water, collected from rooftop gutters, used for the smart-controlled drip irrigation of its living green roof as well as the building’s bathrooms. The foundation says the building's goal is to bring its "operations into closer alignment with the conservation goals of our founders and trustees.”
