Energy efficiency in Campo dei Fiori shopping center - A pilot case of the CASSANDRA project

Share this Post:

In the framework of the EU funded project "Cassandra" a pilot case was implemented in the “Campo dei Fiori” shopping centre in Gavirate in northern Italy.  The main objective of the pilot was to deploy the CASSANDRA software package and evaluate the applicability and potential of Demand Response and feedback programs in the commercial sector to reduce overall consumption at peak times.
In this respect, Politecnico di Milano conducted feedback and demand response trials, which lasted 6 months in total, from September 2013 to February 2014, and involved 11 shops which, along with the shopping mall energy managers, the main pilot participants.

Through the feedback program pilot participants were provided with regular information about their energy consumption and with suggested actions to reduce it. Through the Demand Response intervention a set of monetary incentives were provided to the shops and energy managers to encourage them to shift consumption away from peak times.

Based on the results from both interventions the measurement findings showed that there was a significant change in respect to the following indicators:

  • Reduction in overall electricity consumption
  • Peak clipping
  • Net reduction in power bill
  • Reduction in CO2 emission


The evaluation findings indicated that both programs had a substantial impact on participants’ behaviour given that they increased their awareness of their electricity consumption which lead to a more energy efficient behaviour. In particular, pilot participants managed to decrease their electricity consumption during peak times and thus, in reducing overall their electricity bills. In terms of environmental impact, the feedback and DR interventions helped the shop owners to reduce their electricity usage which lead to a very positive impact on the reduction of CO2 emission arising from electricity consumption.

Lessons learnt

The provision of actual information about energy consumption enables consumers to shift to a more energy efficient behaviour.
