Contact Information

Valladolid is the capital of the autonomous region of Castile and Leon in the Northwest part of Spain, and has a population of 307,052 people (2015 est.) making it northwestern Spain's biggest city. 

The demo site of the REMOURBAN project in Valladolid covers the FASA District, which is located in the south-east of Valladolid, has a surface of 3.5 km2 and belongs to Delicias neighborhood, the first neighborhood built up outside the track, during the 50’s and 60’s decades. With some variations from the original plan, FASA district, which was designed and built up at the beginning of the 60’s for workers of the FASA company, consists of 19 blocks, a tower, a building for the central boilers, a park, some sports facilities and 2 car parks. All the buildings have their axis located on the east-west direction.

The population of FASA district is about 1.180 inhabitants, and its total number of dwellings is 398 (the nineteen blocks come to 342 dwellings, and the tower contains the remaining 56), so the conditioned area reaches the amount of 24.700 m2 (3.900 m2 from the tower and 20.800 m2 from the nineteen blocks). FASA district is a compact residential area of buildings of medium-poor constructive quality in a progressive ageing.

The district is also characterized by its high construction density (135 DU/ha) and high population density (340 inh./ha).

Regarding mobility aspects, the district is located in the south periphery of the city, with a medium level of motorization (400 veh./hab.) and concentrating most of the travels by private vehicle. Also, its location in the traditional entrance to the city from the south makes this district to be positioned in a strategic area of the city regarding mobility.

Low Energy districts actions

  • Monitoring - ICT platform for energy performance monitoring 
  • Retrofitting - 24.700 m2 district retrofitting | 398 dwellings | 1.000 residents | 50% energy savings
  • Renewable heating & cooling - Biomass district heating  
  • Electricity distributed generation - Combined Heat and Power generation (CHP) | Photovoltaic panels on façade (64 kWp)
  • Advanced bems - Advanced Building Energy Management Systems (BEMS) for monitoring of district heating and building comfort controllers

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’ is 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. 

Sustainable mobility actions

  • Full & hybrid electric vehicles - 20 FEV (Full Electric Vehicle) taxis | 3 electric buses (1 FEV and 2 PHEV) | 2 electric cars (FEV) – car sharing fleet | 20 private electric cars (FEV)
  • Charging infrastructure - 4 charging points for electric taxis |1 fast charging point for taxis | 4 fast charging points for electric buses | upgrade of 13 electric vehicle charging points | 20 recharging points in parking areas 
  • Door-to-door multimodality transport - ticketing system based on RFID cards, shared among users from buses, bicycles & car-sharing fleet  
  • Clean logistics - 5 full electric vehicles last mile of delivery in Castile and Leon logistics regional network
  • Intelligent transport systems - smart phone app as an aid to mobility  
  • Incentives - free parking for electric vehicles | taxes reduction for electric vehicles | special lanes for electric vehicles

In this field the actions foreseen for reducing the mobility impact, by means of reducing the energy consumption and CO2 emissions, contemplate the implementation and promotion of use of clean powered ( both public and private) vehicles, while improving the clean transport infrastructure.

Thus, a fleet of alternative fuel vehicles will be deployed for public transport (3 PHEV/FEV buses and 20 taxis) while promoting the utilization of privately owned electric cars (20) and motorcycles, both from citizens and private companies (e.g. hotels, commercial centers).

Five additional electric cars will provide a freight logistics service (‘last mile’ delivery) in specific industrial areas of the city, and 2 others will belong to the city council car-sharing fleet.

The actions aimed at improving the infrastructure consider the implementation of 2 fast charging stations for electric vehicles (one for buses, and another one for taxis and freight logistics vehicles).

All these measures are complemented through ICT technologies and strategies like the development of smart phones apps as an Aid to Mobility (AtM) and a ticketing system or the implementation of unique contactless RFID cards to enhance the intermodality among buses, rented bicycles and car sharing.

Integrated infrastructure actions

  • City information platform - city information platform to collect and storage all the data from the monitored devices
  • Shared infrastructure - access to smart metering infrastructure
  • Road systems - smart phone apps
  • Peer-to-peer transport information – car-sharing municipality fleet (sustainable mobility priority area)

The third set of technical priority actions are related to integrated infrastructures and contemplates the creation of a city information platform, by accessing the smart metering infrastructure in the district and offering data about the indicators related to energy performance, comfort data, mobility aspects, etc.

This platform plays a key role in the management of the improved infrastructures of energy and transport, being also part of the citizens’ awareness strategy and allowing the evaluation the implemented measures results.

The development of smart phone apps allowing the users access to these services complements these strategies.

Society - Non technical actions

  • Community engagement - REMOURBAN common citizen engagement strategy
  • Social media strategy - common communication and engagement strategy 
  • Implementation plan - REMOURBAN common strategy for development of integrated urban plan
  • Funding models - innovative strategy for building retrofitting in multi-owner property districts
  • EU smart cities framework - REMOURBAN common sustainable and smartness evaluation procedure

Expected impacts

  • 50% Energy savings
  • 80% CO2 emissions avoided
  • 5.700 citizens directly involved

Encountered barriers

Raising capital. Attracting private investment was complicated because of the difficulties encountered when trying to explain the benefits of this project.

The project has pursued a strong communication campaign. They have sought to explain the benefits of this type of a project by providing examples of best practices implemented in other similar projects.

Recovering investment. There were some difficulties with the companies which are used to shorter term contracts with a faster return of investment than 10 years. Most of the communities do not want to sign contracts that are longer than 10 years.

In order to accommodate those who were not accustomed to working with longer term contracts and energy efficiency institutions, the project has tried to work with the financial institutions. They were able to agree to obtain better loan conditions, with lower interest rates for the people.

Encountered barriers

Tenant - owner incentives problems. Owners (the municipality) were aware of the merits of this type of projects and were commited to implementation. The tenants were more used to smaller interventions and were less ready for major interventions. 

Project developers have tried to bridge the problems encountered with the tenants via strong communication campaign.
