CommONEnergy: energy refurbishment of European shopping centres

As buildings, shopping centres have some very particular energy needs. They are extensive, much-visited spaces that need an adequate level of thermal comfort and, depending on their activity (as in the case of supermarkets), have other requirements such as refrigeration. This represents a significant energy expenditure that, at European level, is estimated to be 157 Mtoe (according to data from the European Union’s Energy Efficiency Action Plan in 2005). The CommONEnergy project has been set up by 23 stakeholders from ten countries (Spain, Italy, Norway, Sweden, Austria, Belgium, the UK, Greece, Poland and Germany) with the aim of developing a methodology for the energy retrofitting of shopping centres that will achieve a reduction of 75% in the energy demand of these buildings.

The CommONEnergy project is co-funded by the European Union through the VII Framework Programme and is currently at its halfway stage after its launch in October 2013. To date, energy analysis and diagnostic tasks have been undertaken and from now and up to September 2017 when the project closes, the measures agreed under the demonstration cases will be implemented to test their efficacy. The project consortium brings together 23 stakeholders from different EU countries, including three from Spain: the CARTIF Technological Centre, the Valladolid City Hall and Acciona.

All over Europe, there are some 5,700 commercial spaces that account for almost 30% of the entire non-residential building stock. These buildings are frequently perceived as icons of a consumer society, with a high energy demand, high CO2 emissions and a high level of waste generation. Precisely for this reason, the main objective of the CommONEnergy project is to facilitate practical support solutions and tools to transform these spaces into buildings of reference as a result of their architecture and energy efficient systems, reducing their energy bills and at the same time minimising greenhouse gas emissions and improving the image of the centres thereby attracting new customers.
