On 18 October, CTBUH announced the winner of its annual award for the 2023 best tall building worldwide as 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.
