Singapore Green Events - Oasia Hotel Downtown

In the heart of Singapore’s dense central business district, Oasia Hotel Downtown is a prototype of sustainable design in the urban tropics.


The 27-story tower, designed by Singapore-based architectural practice WOHA, has a reinforced concrete structure with an internal curtain wall, prefabricated fibreglass planters on a cantilevered reinforced concrete ledge, and a facade of expanded aluminium mesh panels that allows climbing plants to grow on the building.



Paving the way to green


The building sits on a 50-by-50 meter site, hemmed in by surrounding towers with congested and limited outdoor views. The project brief called for three distinct facilities: offices, hotel and clubrooms. Hence, the architect stacked the three L-shaped blocks and flipped each of them to opposite corners for different views that overlook a sky terrace (at the 6th, 12th, 21st and 27th story). Effectively, the three lower verandas are each sheltered by the one above, open at the sides for transparency, cross-ventilation and daylight. The elevator and building service cores were distributed to the four corners of the building to connect each stack and reinforce the corners of the building form. By doing so, the tower carves out its own internal spaces with a dynamic 360-degree view that is not possible with a typical tower that has a centralized core. It also creates a circulation path that could support varied uses and individualized public spaces, offering opportunities for recreation and social interaction. In addition, rather than a flat roof, Oasia is crowned with a tropical bower—floral, diverse, soft and alive.


Performance

The façade mesh creates a veil, absorbing heat and providing up to 60 percent shade.

The sky terraces are huge overhangs that shade and reduce heat gain, promoting fresh air and reducing energy load for the common areas. These features are intrinsic from the architectural massing and expression, without any equipment and machines. The architecture firm is in contact with relevant institutions for measurements and data collection to evaluate the building’s energy performance and other sustainable features.


Replacing with green

Skyrise greenery is another example of how we can add dimension to the city’s green spaces. The Oasia Hotel Downtown breathes life into the upper reaches of the Central Business District’s skyline. While rooftop and vertical greenery are not new in Singapore, there is increased adoption of this method in new buildings.


The hotel is centrally located in downtown Tanjong Pagar area which is set to be transformed into Singapore's next waterfront city with a hive of business, commercial and residential activities. With Tanjong Pagar MRT station right at the hotel's doorstep, guests can conveniently travel to anywhere in the city.



The hotel makes use of an abundance of open-air spaces throughout the hotel to make your meetings a refreshing one. Take your pick from the 2,500 square feet of event spaces which spread across 2 locations.
