New Sydney icon wins unprecedented seven awards, demonstrates importance of structure renewal to mitigate climate change
Chicago—The Council on Tall Buildings and Urban Habitat (CTBUH) announced the winner of its annual award for best tall building worldwide: Quay Quarter Tower, in Sydney. Winners were also announced in five regional categories, five height categories and a dozen other functional categories (a complete list of categories and winners appears below) at the organization’s annual international conference, themed Humanizing High Density, in Singapore and Kuala Lumpur.
“The global construction industry confronts an emerging dilemma: should we build new structures, or should we renew existing ones to accommodate the anticipated growth in urban density?” explained CTBUH CEO Javier Quintana de Uña. “The pursued remedies can impact not only individual structures but also entire cities and the built environment in general and must take into account environmental, economic and social sustainability. Sydney’s Quay Quarter Tower exemplifies the forward-looking strategies and solutions that address this density dilemma head on, significantly reducing carbon emissions and helping to mitigate the impact of climate change while meeting the needs of its occupants and the surrounding community.”

Quay Quarter Tower, owned by Dexus Wholesale Property Fund (DWPF), Mirvac Wholesale Office Fund (MWOF) and Rest Super, repositioned an existing underused building, the 1976 AMP Center, retaining a significant portion of its beams, columns and slabs, as well as over 95 percent of its existing core, an approach that resulted in an embodied carbon savings of 12,000 metric tons in structure. Additionally, a self-shading façade reduces solar radiation, minimizing mechanical loads on the building, and strategically positioned atria enable natural daylight to permeate the 2,000-square-meter floor plates, improving energy efficiency in the interior. And an innovative removable floor system in the atria allows occupants to remove and replace floor sections, affording flexibility that can accommodate a wide range of uses as businesses grow and work practices evolve, extending the life cycle of the building. As a result of these carbon-reducing features and others, the building exceeds the operational performance of many newly constructed buildings and has achieved a 6-Star Green Star rating.
“But carbon is only part of the equation here; we also focused on connectivity and the community,” explained Liann Lim, Senior Development Manager of Quay Quarter Tower. “The building’s atria create a vertical village, with social spaces that promote interaction among occupants, and activate the workspace, which has achieved IWBI WELL Platinum certification. We also took advantage of Sydney’s temperate climate, extending the internal market hall to external terraces, and the podium’s rooftop park and cafe provide both a new destination and much-needed greenery in a dense urban quarter for occupants and visitors alike.”
As the building rises, the façade gradually shifts toward the east, offering extensive harbor views that include the Sydney Opera House. This design approach ensures that the building does not cast additional shadows over the adjacent Royal Botanic Gardens or the public museum space to the south.

“We’re very pleased with the building’s overarching sensitivity and contribution to the city,” added Lim. “Being recognized by CTBUH as the best tall building worldwide affirms that we’re making a positive impact not just in Sydney and Australia but in the built environment globally."
Quay Quarter Sydney, a precinct anchoring the city’s northeastern central business district, is also leading the way in planning and placemaking innovations. The project's heritage laneway development, Quay Quarter Lanes, was recognized with CTBUH's Urban Habitat Award for its imaginative urban design, which enhances social sustainability and city life.
The annual CTBUH Award of Excellence competition recognizes projects from around the world that employ the most advanced concepts and technologies in sustainable vertical urbanism. It celebrates and amplifies game-changing approaches to some of the most pressing challenges confronting the urban environment today, including mitigating the impact of climate change, reducing carbon emissions, achieving sustainability through an environmental—as well as cultural—lens and equity and affordability in housing, among many others.
Submissions for the Award of Excellence competition were solicited widely earlier this year. Representatives for each project presented to multidisciplinary juries assembled at the organization’s annual international conference, October 16–21. Juries were comprised of CTBUH members from across the globe with expertise in architecture, engineering, construction and other diverse disciplines. Overall category winners were then selected and conferred at an award ceremony and dinner.
