    Urban Identity: a new sustainability model for the Sydney skyline. — Our design aims to showcase a new model for tall building construction around the world. With a novel, hybrid structural basis and an emphasis throughout on next-generation systems design, it brings nature into the workplace, supports economic vitality and points the way to an ethical mode of new construction that will also support socially inclusive placemaking and responsible environmental performance.

    Air Space: well-being through natural ventilation and biophilia. — Research has identified many positive impacts of mass-timber spaces. Here it will help to create healthy and inspiring working environments. Taking advantage of Sydney’s temperate climate, the tower uses an energy-efficient system that balances a naturally ventilated enclosure with strategic use of mechanical air-handling zones. Generous plantings complete the connection to nature.

Atlassian Tower - Sustainability aspirations

The new high-rise building of Atlassian is going beyond star rating systems and claims to be a game-changer for low-carbon construction, high comfort and low energy consumption throughout the whole life cycle. Innovative comfort- and building-approaches and a focus on human well-being in a strong connection to natural spaces and outdoors lead to an exemplary low energy demand and uniquely stimulating environments.

To inform the international architectural competition a test design was developed with the client. The resulting design brief defined clear aspirations for an inspiring architecture with a hybrid steal/concrete/wood structure and healthy workspace design, offering innovative conditioned offices in parallel with natural ventilated offices and protected gardens.

Future workspaces will be more collaborative and closer to nature

Sydney climate offers all year round excellent opportunities for adaptive comfort strategies. With fans to create breeze, excellent comfort conditions can be created. The high-rise building is zoned to provide 35% of the NLA as purely natural ventilated habitats directly connected to park spaces. About 55% of the areas are mechanically conditioned with excellent fresh air supply and radiant ceilings supplied by wet cooling towers.
The building will offer different typologies of thermal zones. People can decide between different working environments, depending on their individual and task preferences. This is highly anchored in the Atlassian working spirit and aspiration to create delight, diverse and comfortable working environments.

Low embodied carbon timber high-rise structure

The building is driven by a desire to reduce the embodied carbon targeting a 50% reduction from a more typical construction on the same site. To achieve this, it looks to maximize the use of timber within the current compliance environment for a construction start next year. 32 of the 39 stories will be formed from glulam and CLT using both panelized and framed construction timber structures.
The tower design uses concrete core for stability and strategically uses a steel frame exoskeleton to support fire separating levels that divide the timber elements structurally into eight independent timber neighbourhoods of between four and seven stories. Low embodied specification of both concrete and steel will be pursued as the design develops.
