News: American firm Skidmore, Owings & Merrill (SOM) has revealed designs for a skyscraper in Jakarta that will be over 500 metres high and will harvest wind energy through an opening at its peak.

With a proposed height of approximately 530 metres, the Pertamina Energy Tower will be twice as high as Wisma 46, currently the tallest building in Indonesia, and will feature an integrated “wind funnel” that generates energy from prevailing air currents.

SOM designed the building as a headquarters for state-owned oil and gas corporation Pertamina and it will be constructed as part of a proposed campus that also includes a mosque, a performing arts and exhibition centre, sports facilities and an energy plant.

The exterior of the tower will be glazed and will gently taper towards the top to frame the opening of the wind funnel. This curved facade will feature solar shades to allow natural light to enter, without the problems of solar heat gain.

“Pertamina Energy Tower’s iconic presence will stand as a model of sustainability and efficiency, as well as collaborative workplace design,” said SOM director Scott Duncan.

“The headquarters’ performance-driven design supports and reflects the ambition of Pertamina’s mission and forges an innovative model of green development in Jakarta.”

The building is scheduled for completion in 2020 in Jakarta’s Rasuna Epicentrum neighbourhood and will accommodate up to 20,000 Pertamina employees.

It is the latest in a string of skyscrapers proposed recently for the Indonesian capital, including a 400-metre structure designed by MVRDV to look like a pile of buildings.

Pertamina reveals plans for SOM-designed tower in Jakarta

Plans were unveiled on Monday for Pertamina Energy Tower, a highly sustainable corporate headquarters in Jakarta, designed by Skidmore, Owings & Merrill LLP (SOM), the renowned architecture, engineering, interiors and planning firm. Created for the state-owned energy company, Pertamina, the large-scale project will feature a performing arts and exhibition pavilion, a mosque, and a central energy plant in addition to the office tower. Rising more than 500 metres above Jakarta, the tower will be a new landmark on the capitol’s skyline.

The architectural expression of Pertamina Energy Tower reinforces the sustainable strategies at the core of its design. Gently tapering towards a rounded top, the tower opens up at the crown, revealing a ‘wind funnel’ that will take 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 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.

The 99-story tower will accommodate 20,000 employees and will be the centrepiece of the Pertamina campus in Jakarta’s Rasuna Epicentrum neighbourhood. Conceived as a city within a city, the campus design endeavours to create a new model for a corporate headquarters – one that is more like a bustling city – with vibrant public spaces and communal meeting areas, such as a 2,000-seat auditorium for lectures and performances and a public mosque. A central energy plant will serve as the energy production hub for the campus, a literal and figurative “heart” from which energy and services will be distributed. A covered walkway known as the “Energy Ribbon” will knit together the constellation of campus programs and span across land bridges and gardens to create an array of accessible public spaces. The project is slated for completion in 2020.

Dutch studio MVRDV is proposing a 400-metre skyscraper for Jakarta that looks like a pile of at least ten separate buildings.

MVRDV, alongside American architects Jerde and engineers Arup, designed the 88-storey “vertical city” as a part of developer’s bid for a site in the south-east of Indonesia’s capital.

The architects explain that the building would comprise just four staggered towers, which would rise up from a commercial podium at the base. Distributed amongst these structures would be a mix of apartments, hotels and offices, as well as shops, cinemas, a mosque and a vertiginous amphitheatre accessed by outdoor elevators.

“Peruri 88 is vertical Jakarta. It represents a new, denser, social, green mini-city, a monument to the development of Jakarta as a modern icon literally raised from its own city fabric,” said MVRDV co-founder Winy Maas.

Gardens, swimming pools and terraces would cover the tiered rooftops, which the architects conceive as a jungle filled with local trees and plants. ”Our inspiration for the commercial podium and public spaces was Java’s natural setting; lush jungle and stone surrounded by expansive ocean,” said David Rogers, design director at Jerde.

If the developer wins the bid, construction will start imminently.

Also this year, MVRDV completed a library inside a glass pyramid and a building covered in QR codes.

Here’s some extra text from MVRDV:

Peruri 88: MVRDV-Jerde-Arup reveal 360.000m2 green mix use project in Jakarta, Indonesia

An international design team made up of MVRDV (overall design), The Jerde Partnership (commercial podium) and ARUP, together with developer Wijaya Karya – Benhil Property, have collaborated to create Peruri 88 – a new landmark icon for Jakarta. Peruri 88 will be a vertical city in one building combining Jakarta´s need for more green spaces with the need for densification. The tower is a 400 meter tall mix use project with retail, offices, housing, a luxury hotel, four levels of parking, a wedding house, a mosque, imax theatres and an outdoor amphitheatre. The team presented the plans to city and site owner Peruri as part of a developer’s bid competition for the prominent site at Jl. Palatehan 4 Jakarta.

Peruri 88 combines Jakarta´s need for green space with Jakarta´s need for higher densities whilst respecting the typologies of the current urban fabric. The site, which is owned by Peruri, is located at Jl. Palatehan 4 Jakarta, a block formerly used as Mint which sits right next to a future metro station.

The mix use project offers a great variety of office and housing typologies, from large office surfaces to living/working units, from lofts to townhouses, from terraced houses to patio living. Each of these stacked urban blocks comes with a semi-public roof park, an abundance of gardens, playgrounds, spas, gym’s, outdoor restaurants and swimming pools available to the inhabitants and office employees. The tall trees on these decks will provide extra shade whilst the height of the parks allows for a cooling breeze.The high rise, a luxury hotel from the 44th floor to the 86th floor, rises from a platform with park, swimming pool and the marriage house. On top of the hotel a panoramic restaurant and viewing platform complete the structure at the 88th floor.

The commercial podium which is located from levels B2 to the 7th floor is designed by Jerde Partnership with MVRDV. Its most characteristic feature is the central plaza, sheltered by the stacked volumes of the mid-rise it offers multiple outdoor layers of restaurants and shadow and natural ventilation. A series of escalators connects the shopping and retail centre to the parks of the mid-rise.

The Peruri 88 commercial podium reflects the city’s historic islands with reflective bodies of water and landscape traversing the public street levels, while integrating a sunken garden plaza.

The buildings structure has five principle cores and is less complex than visually apparent. Four traditional constructed tall towers rise up between which bridging floors will be constructed. Arup will continue to develop and rationalise the structure to satisfy regulations and the budget.

A number of international hotel, retail and apartment operators have shown interest in the building and if the team wins construction will start swiftly.

Indonesian architects Budi Pradono have designed a leaning house for Jakarta with a tree growing inside.

The three-storey Rumah Miring will have a steel frame that tilts towards the street over a swimming pool and driveway on the ground floor.

Though the walls of the house are to be angled, the floors will remain level and will project into balconies on the exterior.

The house is to be clad entirely in glass and will have opaque walls only around the first floor bathroom and the second floor guest bedroom.

Construction is due to commence in September.

Although a rarity on Dezeen, other Indonesian buildings from the archive include a house with a concrete slide and a compact box house – see more architecture in Indonesia here.

Here’s some more information from the architects:

Rumah Miring in Pondok Indah Jakarta

Start to be built on September 2011

The design proposal is a response to the surroundings in Pondok Indah residential area, where most of the people who live there, tend vying to indicate their success or show their wealth indicated by large buildings with Doric columns or Mediterranean style.

This house is quite small compare to other house, made simple as possible with a steel frame that looks mild, by tilting the building, as a whole will show a symbol of anti-establishment.

The program is very simple space with a swimming pool and study room on the ground floor and master bedroom on the first floor, and guest bedroom on the second floor. The main materials used are: recycled wood, glass, steel and concrete are the primary material forming this house. The walls around the site from a neighbor’s house are maintained to show the history and locality.
