Last but not least, the new Apple Park campus in Cupertino, California, is marked for being the world’s largest piece of curved glass and for its awnings designed to prevent rain from dripping onto the building’s glass facades. Moreover, Apple Park also features the world’s largest naturally ventilated building and one of the most energy-efficient buildings in the world. It is expected to require no heating or air conditioning for nine months of the year and it will run entirely on renewable energy. Some of the energy will be produced on site as the building is outfitted with solar panels around its roof.
