R2Cities as model of renovating old buildings

07 june 2018

R2Cities project partners were gathered together in Valladolid in order to celebrate the final meeting of the project and to put in common the main achieved results until now in the Spanish demo site, the Cuatro de Marzo district, in Valladolid.

The building sector is the largest energy-consuming sector in Europe: reportedly it uses 40% of final energy. 75% of buildings are said to be energy inefficient and this primarily relates to the older stock.

However, energy efficient renovations can be expensive and people often do not have the means to finance them. This is why 130 citizens living in the Cuatro de Marzo district welcomed the retrofitting plan of the EU project R2Cities, coordinated by CARTIF.  

To reduce thermal consumption, the energy efficient measures have been focused on façade and roof insulation, windows substitution, boiler upgrading, and on the installation of thermal panelling. To reduce electrical consumption, new efficient lighting systems and presence sensors have been set up in the common areas of the buildings.

The interventions have already triggered interest by other residential communities and given a boost to the construction sector in the area. ‘CARTIF is working in renovating of other districts through similar solutions, while the local builders, involved in R2Cities, are replicating the interventions in other buildings of the same district, without the support of the EU funds this time’, explains Cecilia Sanz, researcher from CARTIF.

CARTIF is monitoring and analysing the savings in CO2 emissions and in energy consumption in the district.

The project, started in 2013, will end this month. The consortium is expected to unveil soon its final results, which could act as a benchmark for future ‘smart’ interventions at local level elsewhere.
