World's first net-zero energy skyscraper

The world's first net-zero energy skyscraper rises in Indonesia

Pertamina, a state-owned energy company in Indonesia, has begun construction on its new company headquarters in Jakarta, a 99-storey “beacon of energy” that will serve as a new standard for sustainable development, said Skidmore, Owings & Merrill LLP, who recently released the design.

The US architectural and engineering firm noted that this is “the world’s first supertall tower for which energy is the primary design driver”.

Shaped like a funnel, the top of the tower opens at the top, capturing wind and sucking it inside to run a series of vertical wind turbines that provide 25 percent of the building's electricity.
Incredibly, its curved façade is precisely calibrated for Jakarta's proximity to the equator, which mitigate solar heat gain throughout the year. On two sides of the building are sun-shading "leaves" — semi-mobile curtains that allow daylight to enter while shielding the building from glare and heat from the sun. Radiant cooling systems replace air conditioners.

Other buildings on campus will be covered by solar panels, but the central energy plant that powers the complex will run on geothermal — a prime, renewable energy source in Indonesia.
