The renovation works of the Mercado del Val in Valladolid (Spain) have started at the end of November 2014.
The first demolition phase has taken place, after completing the public procurement procedure.
This rehabilitation project is part of CommONEnergy, a European project initiated in 2013. The project purpose is to re-conceptualise shopping malls from consumerism to energy conservation. It will investigate the integration of innovative technologies that will be demonstrated in three shopping centres located in Valladolid (Spain), Trondheim (Norway) and Genoa (Italy). Meanwhile, the benefits of installing the developed energy efficiency technologies, grouped in solution-sets, will be simulated in seven further shopping malls throughout Europe (in Austria, Belgium, Lithuania, Italy, UK) that are acting as reference buildings.
The renovation of the Mercado del Val will convert this market into a smart building, with the ambitious target of decreasing the energy consumption to up to 75%. Since the Mercado del Val is a historical and cultural inheritance of the Valladolid city, the deep renovation will not affect the original aesthetics and the architectural value of the building. Façade and installations will be renovated in order to achieve an optimal level of energy efficiency while keeping the traditional layout.
The first step is to evacuate the internal parts of the building, then working on the opaque brick walls between steel columns, to continue with the revision of the rest of metal beams and crossbeams and the roof. The building will gain an “open space” concept, while preserving all the historical design elements.
Then passive solutions and novel equipment developed by the CommONEnergy partners in agreement with the local design team (architects and engineers) will be implemented. Roberto Lollini, the CommONEnergy project coordinator and Sergio Sanz, deputy director of Cartif Foundation’s Energy Division both emphasise the importance of “using the local climate and natural resources such as natural daylight and ventilation.”
In addition to data monitoring, intelligent systems for energy management will be implemented in order to automatically control and adjust the ventilation, cooling and lighting systems. The energy control of the whole building will be centralised to avoid any energy waste. Among the discussed solutions and innovative technologies, multifunctional climate adaptive façades able to control natural ventilation, solar gains and lightwill be used. The shopping centre will be composed by a market hall including traditional food stall, a restaurant zone on a mezzanine floor and a modern supermarket underground. Particular attention is now being dedicated to the refrigeration cabinets, to reduce the energy consumption, CO2 emission and amount of circulating refrigeration gas.
The renovation works are expected to run about 12 months. The works cost a total of € 10,395,164.13 of which € 306,740 are provided directly by the EU, while the remaining part is funded by Valladolid City Council, the Mercado del Val Merchants Assotiation, The Castilla y León Regional Government, and the Spain National Chamber of Commerce. The General Contractor is the Spanish multinational constructor Sacyr Construccion, SAU.
The renovation works in Valladolid already receive a lot of media attention in Spain (El Día, El Mundo, El Norte de Castilla). The architect responsible for the project is José Maria Llanos.
CommONEnergy is also focusing on other case studies. The first one covers the City Syd shopping centre in Trondheim (Norway), which will only undergo a light retrofit without interruption of current activities. The second study focuses on the Ex Officine Guglielmetti in Genoa (Italy), which will be converted from food retail to a shopping mall.
