REMOURBAN Site Valladolid


Project status



Valladolid is the capital of the autonomous region of Castile and Leon in the north-west part of Spain, and with a population of 307 052 people it is the biggest city in the region. The demonstration site of the REMOURBAN project in Valladolid covers the FASA district, which has a surface of 3.5 km2 and is part of the Delicias neighbourhood, located in the south-east of Valladolid. The district was designed and built at the beginning of the 1960s for workers of the FASA company. It consists of 19 blocks, a tower, a building for the central boilers, a park, some sports facilities and two car parks. With a total number of 398 dwellings, the FASA district has around 1180 inhabitants. The buildings in the area are of medium-poor constructive quality and progressively ageing. Its location at the traditional south entrance to the city makes the district part of a strategic area of the city regarding mobility.

With the aim to achieve 50 % energy savings, 80 % CO2 reduction and to directly involve 5700 citizens, a number of actions are underway in Valladolid in the fields of low-energy districts, sustainable mobility, integrated infrastructure and society.

An intensive building envelope retrofitting plan is to be deployed in all the buildings of the district, taking advantage of the homogeneity of the existing construction and aesthetic solutions. The second set of priority actions, planned to achieve a ‘low energy district’, is related to the district heating and domestic hot water systems, through the improvement of the existing thermal district heating (changing the energy source from gas to renewable energy and improving the system efficiency) and the integration of the current individual domestic hot water systems into this thermal network. With respect to mobility and transport, the actions foreseen for reducing the mobility impact, by means of reducing the energy consumption and CO2 emissions, include the implementation and promotion of using clean powered (both public and private) vehicles, while improving the clean transport infrastructure.

All these measures are complemented by ICT technologies and strategies like the development of smart phone apps as an aid to mobility (AtM) and a ticketing system, or the implementation of unique contactless radio frequency infrared device (RFID) cards to enhance the intermodality among buses, rented bicycles and car sharing. Moreover, the success of the actions is ensured through social and non-technical measures such as a citizen engagement strategy, a social media strategy, a strategy for development of an integrated urban plan, an innovative strategy for building retrofitting in multi-owner property buildings, and common sustainable and smartness evaluation procedures.

Demo Site Expected Impact

* Detailed information regarding the technical and financial performance will be available at a later stage.

The overall gross floor area of 24 700 m² is to be refurbished in the Valladolid demo site. With respect to the energy and mobility measures , the expected annual final energy saving is 2222 MWh; the total CO2 emission savings amount to 1147 tons per year.



* Detailed information regarding the technical and financial performance will be available at a later stage.

The actions and measures being implemented in Valladolid within the REMOURBAN project are:

Energy efficiency in buildings
