To prove that architecture and our built environment can coexist harmoniously with our planet, eliminating waste, circulating materials and regenerating natural systems: this is the goal of the “Circular Economy Manifesto” developed by Curator #CarloRatti (@crassociati) with guidance from @arupgroup and input from the @ellenmacarthurfoundation. The Manifesto calls on Participants in the 19th International Architecture Exhibition (#Venice, 10 May > 23 November 2025) and on the Participating Countries to collaborate to make #IntelliGens a truly circular Exhibition.

CRA-Carlo Ratti Associati, in collaboration with IPI, has unveiled a design to adaptively reuse Palazzo Micca, a 19-story modernist tower in Turin, Italy. The project transforms the building into a public-friendly space, crowned with a new elevated plaza offering sweeping panoramic views of the city.
The design emphasizes sustainability by reusing materials and converting office space into housing. Key features include a permeable ground floor and an arcade inspired by Turin’s iconic passageways, enhancing public access.
The project aims to revitalize the tower while promoting sustainable urban development.

A.I. Timber, a project by CRA`s startup Maestro, has been longlisted for the Dezeen Awards 2024 in the sustainability category, recognizing its material innovation 🥳
A.I. Timber reduces waste by preserving the natural shapes of trees, rather than cutting them into standard boards. Using A.I., Maestro fits logs together like a puzzle, creating interlocking timber panels.
This approach tackles the problem of wood waste in sustainable construction, providing an alternative to conventional methods that produce substantial waste.
The project aims to minimize the environmental impact of the construction industry, particularly considering the high emissions from materials such as cement.

Hot Heart, developed for the Helsinki Energy Challenge to help the city achieve carbon-neutral heating by 2030, functions like a giant thermal battery. Low- or negative-cost renewable energy is converted into heat, stored in the tanks and withdrawn into the city’s heat distribution channels during the winter.
The project features an archipelago of 10 heat-storing basins, acting as thermal batteries while also serving as recreational spaces with tropical ecosystems. The system, powered by AI, stabilizes the energy grid and is adaptable for other cities. In addition to its environmental benefits, Hot Heart offers unique public spaces, blending nature and technology.

Today we talked with Claudia Dorman-Alonso, Strategy and Innovation Associate at Carlo Ratti Associati (CRA).
Claudia trained as an architect, earning her bachelor`s degree at Oxford Brookes University before moving to Italy to complete her Master’s in Architecture Construction and City at Politecnico di Torino, where she graduated with honors and a special mention. After university, Claudia gained experience as a multidisciplinary designer at various firms in London and as a technical designer at Permasteelisa in Veneto. She joined CRA in November 2022.
At CRA, Claudia is part of the Strategy and Innovation team, which collaborates with private and public stakeholders to develop innovative architectural and engineering solutions with positive environmental and social impacts. Notably, she has contributed to projects like the proposed replacement for the Francis Scott Key Bridge in Baltimore, Maryland. After the bridge`s collapse in March 2024, CRA, along with WeBuild and Michel Virlogeux, proposed a cable-stayed design that reimagines the entrance to Baltimore Harbor while enhancing safety and adaptability. Claudia is also involved in the feasibility studies for the CRA Hot Heart and Cool Heart Project, a floating structure designed as a giant battery that stores renewable energy from wind, solar, and other sources to provide heat during winter.
She is passionate about the transformative power of design, the wise use of technology, and the integration of natural and artificial elements in urban development.
