Designed as the world’s first supertall building for which energy is the primary design driver, SOM’s innovative yet unrealized concept for a net-zero tower in Jakarta continues to inspire.
Unveiled in 2013, the design for Pertamina Energy Tower presented a vision for a stunning new landmark rising more than 500 meters above the capital city’s skyline. Complemented by a performing arts and exhibition pavilion, a mosque, and a central energy plant, SOM designed the 99-story “beacon of energy” to set a new standard for sustainable development while bringing together 20,000 employees on an innovative, dynamic campus.
SOM designed Pertamina Energy Tower as the world’s first supertall tower for which energy is the primary design driver. Targeting net-zero energy, sustainable strategies at the core of its design are exposed in its simple profile and sophisticated architectural expression. The tower’s design opens up at the crown, gently tapering to reveal a “wind funnel” that takes advantage of the prevailing winds and increased wind speeds at the upper floors to generate energy.
Precisely calibrated for Jakarta’s proximity to the equator, the tower’s curved facade is designed to mitigate solar heat gain throughout the year. Exterior sun shades dramatically improve the workplace environment and save energy by reducing the need for artificial lighting in the office interiors.
Planned for Jakarta’s Rasuna Epicentrum neighborhood, the campus was envisioned as a city within a city, while serving as a model of sustainability, efficiency, and collaborative workplace design.
A 2,000-seat auditorium for lectures and performances and a public mosque offer vibrant public spaces and communal meeting areas, while a central energy plant creates the energy production hub for the campus—a literal and figurative “heart” from which energy and services would be distributed. The “Energy Ribbon,” a covered walkway that provides sun and rain protection and generates energy through photovoltaics along its roof surface, links the campus, spanning across land bridges and gardens to create an array of accessible public spaces
