CommONEnergy demo site in Modena is reopened

01 october 2016

This supermarket of ca. 1200 m2 selling area, located in a residential area close to Modena’s centre, underwent renovation during the summer 2016, before reopening in September.

The supermarket is now managed by COOP Alleanza 3.0, while the retrofitting process was supported by INRES (for the stages of study, design and implementation) and the CommONEnergy partners, among them CARTIF, who suggested and implemented solutions and technologies as described below.

Around 50 workers were onsite per day during the 14 weeks the works lasted. The total requalification cost (supermarket and gallery) was 2.500.000€.

The innovative solutions of CommONEnergy include:

  • Integrated (coupled) solutions for HVAC and refrigeration;
  • Natural and artificial lighting (solar tubes, light tubes, LEDs): artificial lighting in gallery, adjustable in intensity and colour to simulate daylight. The supermarket will be also equipped with a natural lighting system, using the passage of solar tubes through the rooms of the first floor to the roof;
  • Integrated management system (IBEMS) for the gallery and supermarket, gathering information and feedback on the systems;
  • Thermo-reflective paint for the exterior, applied on a portion of the flat roof. Good part of the roof will be painted with light grey paint additive, which reduces the thermal loads of the building. In this case the positive effects will influence the first floor rooms, in direct contact with the flat roof;
  • Energy modelling in dynamic regime, which highlighted the possibility of obtaining results intervening in minimum building envelope measures as well, thanks to thermal insulation and the use of double-glazing for new window frames;
  • Insulation of the structure to summer irradiation and winter heat loss.

Implementing the previously stated technologies and solutions had several objectives and benefits: 

  • Reducing energy demand and thus reducing the operating costs;
  • Reducing demand of primary energy, thus lowering the GHG emissions and improving the building’s sustainability;
  • Creation of new jobs, a new class of workers with technical skills and increase of contractors coming from small and medium enterprises (SME);
  • Improved comfort within the commercial area.

62 workers are now employed in the renovated supermarket, where various ranges of products can be found: food, home products, etc., completed with vegan and organic sections. The shop is opened 7 days a week, with a reduced timeframe on Sundays. The supermarket was completed with a para-pharmacy of 76 m2 and a bar with an ice-cream shop of 67 m2, participating to the program to revive the R-Nord area.

In the past couple of years, this neighbourhood experienced a social degradation, which encouraged the city of Modena to define a project requalifying this area, both from a social and functional point of view. The supermarket’s retrofitting was therefore included in the overall neighbourhood requalification.

In addition, the project consortium is gathering this week in Madrid (Spain), and they will visit the Mercado del Val, demo site of CommONEnergy in Valladolid (Spain), on Wednesday, in order to know the innovative solutions applied in this shopping centre located in the Valladolid’s centre.

Besides the supportive of the implementation of solutions in the Spanish demo-site, CARTIF has been responsible for energetic audits to diagnose the starting situation of the three demonstrators. The Spanish Centre has participated on the BMS development, mainly on the creation of drivers and software/hardware interface for different elements focusing on the three demo sites. The center has leaded tasks concerning the interaction with energy grid and monitoring of the effectiveness of the assessed solutions at demo-cases.
