The Quay Quarter Tower in Sydney has been just been awarded the "best new tall building" of 2023 by the Council on Tall Buildings and Urban Habitat (CTBUH). Deigned by 3XN and BVN, it's a great adaptive reuse story.
The project is a renovation and expansion of an existing 1970s building. And the team managed to retain 65% of the original structure (slabs, columns, and beams) and 95% of the original core.
This results, according to their calculation, in 12,000 tons of embodied carbon savings. The equivalent of 35,000 flights between Sydney and Melbourne. At the same time, the team managed to add 45,000 m2 of new floor area to the site by grafting new slabs onto the existing ones.
But let's get back to these carbon savings.
According to this site, there are 37 direct fights between Sydney and Melbourne each day. That's about 13,505 flights per year, meaning that the carbon savings from not fully demolishing this building (and starting fresh) are equal to about 2.6 years of people not flying back and forth between these two cities.
If you consider how long buildings typically last (this one was relatively young at under 50 years), it kind of makes buildings seem less bad. Of course, we're only talking about and comparing embodied carbon. There's also the ongoing operation of the building.
In any event, a deserving project. Congrats to the team. For more on the project, click here.
