In order to achieve the goals related to low energy districts in Valladolid, an intensive building envelope retrofitting plan is to be deployed in all the buildings of the district ( 24.700 m2 of conditioned area), taking advantage of the homogeneity of the existing construction and aesthetic solutions.
Thus, the energy demand of these buildings is drastically reduced through the implementation of cost-effective strategies related to the walls, roofs and windows retrofitting, while allowing the implementation of active energy production measures in the building envelope (e.g. Building Integrated Photovoltaic).
The second set of priority actions planned to achieve “low energy district” are related to the district heating and DWH systems, through the improvement of the existing thermal district heating (changing the energy source from gas to RES and improving the system efficiency) and the integration of the current individual DWH systems into this thermal network.
Finally, these actions will be combined with an ICT platform aimed at monitoring the energy performance and integrated into an advanced controlling system for the district heating and indoor spaces comfort.
