PERTAMINA ENERGY TOWER BY SOM

The dramatic centerpiece of a new consolidated headquarters created for the Indonesian state-owned energy company, the Pertamina Energy Tower will rise more than 500 meters above Jakarta as a stunning new landmark on the capital’s skyline.

Complemented by a performing arts and exhibition pavilion, a mosque, and a central energy plant, the 99-story "beacon of energy" will represent a new standard for sustainable development, bringing together 20,000 employees on its innovative, dynamic campus.

Following SOM's holistic design approach that integrates architectural design, structural engineering, and sustainable engineering services, Pertamina Energy Tower is the world’s first supertall tower for which energy is the primary design driver. Sustainable strategies at the core of its design are exposed in its simple profile yet sophisticated architectural expression.

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. Overall, the development will reduce water demand and target zero discharge while reducing carbon dioxide emissions by 26% by the year 2020 and generating 25% energy from renewable resources by the year 2020.

Located in Jakarta’s Rasuna Epicentrum neighborhood, the iconic campus will serve as a city within a city, blending together living, working and playing 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 will serve as the energy production hub for the campus—a literal and figurative “heart” from which energy and services will 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.

ANANTA LEGIAN HOTEL BY AIRMAS ASRI

"Ananta Legian is situated behind Legian Beach, and due to the lack of sufficient area, it was built on a long, narrow site surrounded with local settlements and hostelry buildings. This situation makes the hotel virtually hidden by the other buildings, making it invisible from the beach.

Consequently, the seascape is difficult to be enjoyed from the hotel area and, although the hotel is located within walking distance from the beach, access is not easy.  But the difficulty in accessing the hotel area is offset with an opulent lobby building that welcomes visitors in the drop-off area before their vehicles head to the basement parking area.

The lobby is a pyramid-like building with blunt top inspired by the form and characteristic of Balinese glass handicraft, and the floral Balinese traditional ornament. In order to create a sense of sacredness and a philosophical meaning, the ornament was transformed into its traditional element accentuated by Patra Sari—a painting made by I Wayan Lungguh, a local artist—and other local paintings on the lobby building.

These paintings, far from being merely accents in an interior, have powerful meanings on divinity, life, and eternity. These paintings were converted into a handmade carving with Glass Fiber Reinforced Concrete (GRC) material and were applied throughout the lobby as secondary skin which help to reduce the heat from the sun.

The lobby building was constructed with steel frame structure to pin two layers, the glass inside and the carving outside. These layers are separated by a 50-centimeter wide space between the glass and the carving for maintenance needs. This layering system creates an aesthetic three-dimensional effect to the GRC carving, and a shady and mild ambience to inside of the building. 

To prevent overheating on the inside of the building, it was designed with an open gate and the glass layer served as natural ventilation. At night the lobby is flooded with light, transforming it into a beautiful carved lantern. The attractive lobby is also intended to complement the simple form of hotel building behind it.

As a focal point and façade of the building façade, the lobby is not only beautiful, but also poignant. The hotel building was arranged in a simple U-shaped building with a nook on the left side in order to create a more dynamic sense of space. The lack of view was resolved by creating a view for guest coming and for guest who already in the hotel. 

An open space located in the middle of the hotel area acts as a latar –the open space in Balinese traditional house. In this area, the open space functions as public facilities equipped with a swimming pool, a restaurant, a coffee shop, and a meeting room. The swimming pool is located precisely in the axis of the lobby, making visitors feel welcomed with the water that reflects the ambience of its surrounding.

The swimming pool and the lobby pavilion was designed in such a way that create impressive view. A grand stairs is also located in the same axis to connect the lobby and the public facilities on the semi-basement floor. This stairs is designed to bring visitors to experience a ‘ceremonial’ atmosphere that usually reserved for pedanda—the high priest in Bali.

Water element, such as a pond with four frangipani trees and artificial waterfall, is also prominent in the entire open space. These elements create a stronger experience of continuous space in this narrow site. In order to soften the massive wall that surrounds the open space, metal frameworks covered with vines are applied to create green walls. As a result, this open space creates a relieving and warm ambience for guests, become a view for the guest to enjoy."

CENTRAL PARK BY DP ARCHITECTS

Central Park is conceived as the gateway to a greater metropolitan region along Jalan S Parman Highway in Western Jakarta, Indonesia.

 

Developed around a central garden and plaza on a site of 8ha, this project provides the dense surrounding district with a new and powerful identity of openness and landscape.

Central Park’s arrangement in plan takes the form of an arch. At the focal point of this geometry is a plaza about which the project’s structural development and functional zones of activity revolve.

The four elements composing the arch — a retail podium, 40-storey office tower, a hotel, and a set of three 48-storey apartment towers — are laid out to provide two strong poles of activity which disperse crowds into the central spaces of the shopping podium and park.

The complex is oriented north-south to reduce heat gains. Activity decks — outdoor dining spaces and viewing galleries — perform as shading devices for the podium below, where views of the adjacent park extend into the spaces of shopping and dining; these decks are designed with a degree of curvature reflective of the plaza’s organic characteristics.

Qualities of openness are ingrained functionally and thematically within the retail podium. In plan, shops are arranged along a narrow floor plate — this layout in tandem with a highly transparent facade allows ample daylight and views of greenery to reach the interior spaces.

Three atriums carry individual characters of temperate, tropical and arctic gardens to inject the 175,600sqm of retail space with an urban nature.

These large-scale atriums merge with the outdoor park to form an assembly of civic spaces and pedestrian thoroughfares as a new dynamic centre for the community.
