Bocconi’s Environmental Energy Project

Bocconi has begun a project that will see the creation of an electricity, heating and cooling plant, aimed at meeting the University’s energy needs for existing buildings and those soon to be completed.

Il progetto si articolerà in tre fasi distinte:

Stage I: Heating pump and connecting loop between the buildings in the Bligny-Roentgen area (complete);

Stage II: Cogeneration with gas motors in the former Centrale del Latte area (to be constructed);

Stage III: Combustible cells and solar energy plant for the whole Bocconi Campus (to be constructed)

First Stage

In the first stage, completed in 2007, two production centers for hot/cold fluid were designed and installed in the Piazza Sraffa 13 and Bligny/Roentgen buildings.  These were interconnected and capable of also serving the Bocconi 8 and 12 buildings, and the Piazza Sraffa 13 building.

Advantages of the project

  • Containment of consumption (energy saving of around 40%);
  • Reduction in environmental impact (elimination of pollution at the local level);
  • Contribution to controlling the rise of groundwater;

The plant uses 3 heat pumps of around 1500kW each, using groundwater:

  • Cooling power                  7500 kWt
  • Heating power                   4900 kWt
  • COP cold                           7
  • COP hot                             4

In the winter of 2011-12, despite the colder temperatures than the previous year, only the central production unit in the Via Roentgen building was used to heat all the University buildings in the Sraffa-Bocconi-Bligny- Roentgen area, resulting in significant financial and energy savings, as well as less pollution.

These results are because of the district heating/cooling system connecting the Roentgen, Bocconi 8 and 12 buildings, and the Piazza Sraffa 11 and 13 buildings, to the production unit in the Via Roentgen building which, if necessary, can be supported by the district heating/cooling system of hot and cold liquid produced by the central heat pump in the Gardella building through the connection between the two central heat pumps.

The reduction in the number of thermal engines throughout in the area has led to the reduction in contracts to supply energy gas/electricity wastage in bringing the plant to temperature.

The energy advantages are expressed in COP (coefficient of performance) overall (plant energy yield) which today is 4.5 for heating and 7 for summer air conditioning; less energy is used than in the past with a resulting reduction in overall costs.

Because of the above, the buildings in Via Roentgen1, Via Bocconi 8 (SDA), Via Bocconi 12 (dorm), Piazza Sraffa 13 (Velodrome), and Piazza Sraffa 11 now have zero emissions.

At the end of the third stage, the center will be outstanding technologically and highly efficient, resulting in a considerably reduction in environmental impact, because of the use of cutting-edge technology in the production of electricity, heating and cooling (combustible cells, heat pumps, internal combustion engines), with high level of operational reliability.
