Jakarta's 99-story Pertamina tower makes energy key design principleDecember 13, 2013 by Nancy Owano in Technology / Energy & Green Tech
(Phys.org) —A 99-story skyscraper created for the Indonesian state-owned energy company, Pertamina, which is scheduled for completion in 2020, will carry the distinction of becoming Jakarta's tallest landmark, rising over 500 meters high above Jakarta, and will accommodate some 20,000 workers. However, "tall" is not the key distinguishing factor in the works; the renderings of the sky-piercing building have been released by the architectural and engineering firm Skidmore, Owings & Merrill (SOM); the design shows how the Pertamina Energy Tower is to be, in the words of SOM, "the world's first supertall tower for which energy is the primary design driver." The building is designed to harness wind energy.
Resembling the petals of a flower, the tapered peak is to leverage wind energy. The crown reveals a wind funnel that will harness winds at the upper floors to generate energy. Then, there is the "Energy Ribbon," a solar-paneled roof walkway throughout the campus. This covered walkway is to provide both sun and rain protection with energy generated through photovoltaics along the surface of the roof. The need for artificial lighting in the office interiors will be lessened with support from exterior sun shades.
The building will include a 2,000-seat auditorium for lectures and performances and a mosque. SOM calls it "a city within a city, blending together living, working and playing while serving as a model of sustainability, efficiency, and collaborative workplace design."
The energy-harnessing theme is clear. SOM said the development will reduce water demand and target zero discharge while reducing carbon dioxide emissions by 26 percent by the year 2020 and generating 25 percent energy from renewable resources by 2020.
According to the Jakarta Post, local companies will also participate in the project as consultants, and also to work on the project's central energy generator.
As a state-owned company, Pertamina said its mission is "to carry out integrated business core in oil, gas, renewable and new energy based on strong commercial principles both inside and outside the country."
