Transforming Urban Microclimates through Design: the ARIA regeneration project.

The ARIA project exemplifies urban regeneration by transforming an industrial site in northern Italy into a sustainable work environment and inclusive public space. Central to the redevelopment is the application of microclimate modeling, which guided design decisions to optimise thermal comfort and air quality. Compared to the current situation, the regeneration project demonstrates a reduction in air temperature by up to 1.5°C and mean radiant temperatures by up to 30°C during peak summer hours, significantly mitigating the urban heat island effect in the area.

The use of microclimate modelling was embedded within the design process, not as a final assessment but rather as a reiterative reference, allowing the project team to adopt design strategies in response to specific environmental conditions. The method promoted a collaborative environment among architects, landscapers, and environmental scientists, ensuring the development of data-driven and context-specific integrated solutions.

Among the different design strategies applied, material reuse is a key component, with the project utilizing bio-based, carbon-negative materials to reduce the environmental impact. The regeneration also incorporates extensive tree canopies, selected for their ability to improve air quality and reduce pollutant loads.

The project shows a practical methodology for integrating scientific research into urban design practices by detailing specific climate-responsive strategies and their quantifiable impacts. It highlights the importance of using empirical data to inform spatial decisions and boost functional and sustainable urban project implementation. This initiative not only has the potential to revitalize a significant area of the city but also sets a precedent for future urban regeneration projects worldwide, emphasizing the necessity of climate-responsive design and the profound impact of climate research on architectural practices.
