Aria is the requalification project of the former Slaughterhouse of Milan, that aims to become the first Carbon Negative Area in the city. The project is the winner of the second edition of Reinventing Cities, the international competition launched by the City of Milan in collaboration with C40 for sustainable urban regeneration.

ARIA: HIGHLIGHTS

Actions for “climate positivity” The objective is not only to reduce the CO₂eq emissions produced by the intervention to zero, but to remove emissions from the surrounding city. Among the strategies adopted:
  • 36.000 mq of photovoltaic surface area.
  • Renewable Energy Communities: communities that consume, produce and supply others with their self-produced energy using renewable methods.

Presence of relevant cultural and training institutions

  • IED: 30,000 mq intended for the main campus of the European Institute of Design, a prestigious international institution for education and research in the disciplines of Design, Fashion, Visual Arts and Communication.
  • Pod Science & Art District: 6,500 mq for a new Science District. Exhibitions, events and laboratories for the production and dissemination of science and the enhancement of STEM (Science, Technology, Engineering and Mathematics).

Dynamic design and inclusive use of spaces and services

  • Residents and operators in the district will share spaces and services for self-managed activities and develop inclusive social projects.

A neighbourhood app for residents, users and community manager

  • Smart access to neighbourhood information, reservation of spaces and services and monitoring of energy consumption.

THE FIRST CARBON NEGATIVE AREA IN MILAN

ARIA will be Milan’s first Carbon Negative area: it will produce its entire energy needs on-site from renewable sources (zero carbon), and will also transfer a surplus of clean energy to other areas of the city, thus lowering the CO₂ produced in the city (carbon negative).

A complex challenge, if we consider the size of the site and the different uses of the buildings: about 15% recovered pre-existing buildings; 35% new residential areas (most of them affordable housing); more than 40% mixed use (accommodation, offices, laboratories, exhibition and commercial spaces); a student residence; a medical centre; the IED Campus.

Becoming a Carbon Negative Area will be possible thanks to a series of interconnected actions.

    • Efficiency requirement
      Thanks to the use of state-of-the-art building technologies, the energy requirements for air conditioning, ventilation, and hot water production in new buildings are at least 40 percent lower than those of standard state-of-the-art buildings.
    • Only renewable energy
      100 percent of energy needs are met through a large photovoltaic system with an area of more than 36,000 m² that generates the energy for the site’s heat pumps and cooling machines.
    • Efficient networks
      Energy generated by the photovoltaic system is best managed and transmitted through an ultra-low temperature (15°-25°) 5th generation district heating/cooling that reduces consumption: the energy savings of this network compared to more traditional systems is 15%.
    • Real-time monitoring
      A monitoring system is planned for energy consumption and indoor environmental conditions that can provide information to occupants and the facility manager. Residents can monitor their consumption through the Redo App
    • Results: less consumption
      In light of these measures, Aria’s energy consumption shows significant reductions compared to Business As Usual (BAU).

  • Energy Surplus and Carbon Negative
    The energy produced by the large photovoltaic system, and the savings from the low-temperature grid, create a surplus of renewable energy. This surplus will be used by users (residents, educational institutions, and businesses) off-site. The release to the “energy community” to citizens not residing in the project area is the key to a new paradigm: the Carbon Negative Area. That is, Aria contributes to lower CO₂ emitted elsewhere in the city and is an active factor in “rebalancing” city-scale emissions. This scheme can become a case study as it can be replicated in other development areas of Milan. In fact, it allows the implementation of a proper ecological transition with favorable economic implications for users.
