Latest Apple headquarters drone video depicts carbon fiber auditorium roof, solar installations

The underground auditorium was previously not enclosed all the way around, but is now nearly completely clad. The largest carbon fiber roof in the world has been uncovered, and is shown in the video.

Apple's main research and development building appears functionally complete from the exterior, with a full set of HVAC equipment installed for the first time. Significant progress on the Tantau Avenue research suite is shown as well.

The 20,000 car main parking structure appears to be complete with a full solar installation adorning the roof.

The main "spaceship" headquarters is completely covered in glass panels, and the solar assemblies on the roof also appears complete. Additionally, adjacent landscaping is being fleshed out

While a great deal of work remains on the entire campus, a large amount of work has been done on landscaping, and the area in the center of the "spaceship" since the last video in October, and this most recent one. the Structures in interior of donut underway, much work remains

In 2011, Steve Jobs announced the project to the world, saying over 12,000 employees would work in the 2.8-million-square-foot spaceship-styled structure. Edible landscaping, walking paths, and other "green" measures are being implemented during construction, to minimize the overall impact the facility makes on the environment.

Apple's related Phase 2 project adds additional workspace adjacent to the main headquarters, and includes a renewable energy-powered small data center.

A new micro-grid installed on the campus is reportedly capable of handling about 75 percent of the facility's power requirements during work hours, supplemented by Bloom Energy-provided fuel cells. Bloom Energy provided similar cells to Apple previously for use at the North Carolina data center.

The City of Cupertino recently announced delays for the Campus 2 project, indicating that main construction won't be done until the beginning of 2017, and that landscaping won't be finished until the second quarter of next year.
