According to SOM, Pertamina Energy Tower is the world’s first supertall tower for which energy is the primary design driver. Gently tapering towards a rounded top, the 99-story tower opens up at the crown, revealing a wind funnel’ that will take advantage of the prevailing winds and their increased speeds at the upper floors to generate energy. Precisely calibrated for Jakarta’s proximity to the equator, the tower’s curved facade will mitigate solar heat gain throughout the year. Exterior sun shades will dramatically improve the workplace environment and save energy by reducing the need for artificial lighting in the office interiors.
