Ilias Papageorgiou, founder of Greek studio, PILA, presented his firm’s revamp of a 24-story tower in Piraeus, a port city neighboring Athens. The office building had been nearly vacant since its construction in the early 1970s. The architect outlined the strategies for bringing the long-dormant structure back to life, including a new facade of louvers, which, though fixed, give the appearance of rotation as one moves around the building. The louvers shield a new skin of high-performance glazing, replacing the original curtain wall, which was carefully dismantled and recycled. Even the gaskets, said Papageorgiou, were reused to make athletic turf.

Structural engineer John Ochsendorf, a professor at MIT, and Juliana Berglund-Brown, a PhD researcher at the school, gave a joint talk on designing for circularity and low-carbon construction technologies. To illustrate how varied two buildings for the same use could be in their environmental impact, Ochsendorf pointed to the Bird’s Nest, the stadium built for the 2008 Olympics in Beijing, and the stadium built for the 2012 games in London. The former has an embodied carbon intensity of 1,300 kgCO2e per square meter, while the latter has one of only 250 kgCO2e per square meter. “We could build five London stadiums for every Bird’s Nest,” he said. Meanwhile, Berglund-Brown advocated for using salvaged materials—steel in particular—in new buildings, with Ochsendorf recommending “designing with the beam you have instead of the beam you want,” and adding, “we need to get creative and stop the cycle of build-demolish-landfill.”

Their talk was followed by a presentation by Brian Raff, vice president of Sustainability & Government Relations at the American Institute of Steel Construction, who discussed ways the steel industry in the U.S. has moved toward cleaner production and promoting steel reuse.

A panel discussion pivoted away from buildings, instead focusing on landscape, with Anne Whiston Spirn, professor of landscape architecture and planning at MIT, and Chris Hardy, senior associate at Sasaki’s Boston office, presenting two urban projects at very different scales—from neighborhood regeneration in West Philadelphia to reimagining the former Athens airport.

Merritt Bucholz and Karen McEvoy, founders of Dublin-based Bucholz McEvoy Architects, concluded the day-long conference with a keynote highlighting their firm’s climate-attuned architecture. Among the civic projects that the duo presented was the new headquarters of the Toronto and Region Conservation Authority (TRCA), whose mission includes regulating development in the surrounding area to ensure responsible management of water, land, and natural habitats, as well as to protect it from extreme weather events, especially flooding.

The next Sustainability in Practice conference will take place in September at the Illinois Institute of Technology in Chicago alongside the magazine’s annual Women in Architecture Awards and coinciding with the city’s decade-old architecture biennial.
