Main R&D&i Projects


Camino de Europa is a project that seeks to transform the cultural experience of pilgrims and revive the local economy of the municipalities that make up the French Way. Thanks to Blockchain technology, pilgrims and producers interact securely and reliably to purchase local artisanal products, enjoy differentiated cultural experiences or support projects aimed at sustainability and the survival of the Camino de Santiago and its traditions.

It is a project financed by the European Union with NextGeneration EU funds through the Recovery, Transformation and Resilience Plan promoted by the Ministry of Industry, Trade and Tourism.

CENER is a technological partner of the project, which aims to position El Camino de Santiago as one of the world’s benchmark destinations in sustainable tourism through a “Carbon Neutral Passport” system that allows pilgrims to measure and register their carbon footprint. CENER will develop a technological platform based on blockchain technology for the registration of emissions credits, which will include a carbon footprint self-assessment tool for establishments linked to El Camino.

Start date: 01/06/2022
End date: 30/11/2024

Main objetives: 

Development of an innovative new generation of high efficient heat pump for air conditioning and provision of domestic hot water, to allow a full decarbonization of high energy efficient dwellings.

Specific objectives:

  • To develop and validate a simulation model in order to design and optimize the system, meeting the necessary ventilation, DHW, heating and cooling demands.
  • Construction, development and optimization of the thermoelectricity-based devices that make part of the systems: aerothermal energy, post-heating/cooling unit, underfloor heating/cooling, and storage with an intermediate stage.
  • Development of a regulation strategy to optimize the energy performance, in both winter and summer modes.
  • Verification of the performance and energy efficiency of the integrated unit in a dwelling in Pamplona. Quantification of the decrease in energy consumption compared to current systems.

CENER’s role:

Strategy for the joint operation of the different components that make up the compact air conditioning and DHW supply unit. Collaboration in the design and validation of the experimental results of the project. Computational study of the pilot case. Economic analysis and conclusions.

The Smart Readiness Indicator (SRI) is a common EU methodology that rates the smart readiness of buildings (or building units) for their capability to perform three key functionalities: (a) optimisation of energy performance and operation, (b) response to the needs of the occupants, and (c) adaptation of operation to provide energy flexibility, including the ability of the building or building unit to enable participation in demand response. The SRI was introduced in the 2018 revision of the European Energy Performance of Buildings Directive (EPBD) as a way to emphasize the role of smart building technologies – such as technologies for building automation, control and monitoring of equipment operation – in improving the energy efficiency of buildings and their capability to be active components of the future EU energy system.

The SRI2MARKET project aims at supporting Member States on successfully planning for the rollout of the SRI in their national regulation and markets. In particular, SRI2MARKET will work on specific Member States and with general objectives that are differentiated. Member States with official test phases launched: Austria and France; Member States with active interest in the SRI: Portugal and Spain and Member States where SRI2MARKET can lay the groundwork for policy makers to decide how to proceed with the SRI: Croatia and Cyprus.

Project objectives:

  • Support the targeted countries on introducing the SRI into their national regulation
  • Propose public funding schemes to finance SRI upgrades in buildings
  • Develop tools to guide SRI assessors and streamline building assessments
  • Provide training to EPC assessors on the SRI and the methodology of its calculation
  • Set up SRI pilots at national level so as to identify best practices for SRI assessments
  • Provide recommendations to building owners and facility managers on cost-effective SRI upgrades


36 months (November 2022 – October 2025)

CENER role:

CENER leads the development of an online tool for the SRI assessment, together with an e-learning platform, which will strongly promote the knowledge, implementation and deployment of the SRI into the market of the different member states involved in the project. CENER also leads the development of the database that will collect real SRI case studies, which will engage relevant stakeholders in the field and will be very relevant to draw the future road maps of the SRI implementation.

CENER is coordinating the European project STARDUST, in which the so called lighthouse cities of Pamplona, Trento (Italy) and Tampere (Finland) will implement different innovative urban solutions in the field of energy, electric mobility and smart buidings, by means of the most advanced ICT solutions and Internet of Things (IoT). This R&D project on Smart Cities is co-financed by the European Commission on the call Smart Cities and Communities – SCC1 of the Framework Programme for Research and Innovation Horizon 2020 (contract nº 774094).

STARDUST started on October 2017, and will last five years. The STARDUST consortium is composed by 29 partners from 9 different countries: 7 cities, 4 research institutions, 6 SMEs and 13 industrial partners. The budget of the project is 21 M€, and the funding coming from the European Commission amounts to 18 M€.

The Spanish partners in this big project are, apart from the city of Pamplona and CENER as coordinator, the Government of Navarre, Nasuvinsa, Zabala Innovation Consulting, Jofemar, the Public University of Navarre, SICE and Naturgy.

CENER takes part in the European project EXCESS, whose aim is to show that it is possible to transform nearly-zero energy buildings into positive energy buildings. This means that a building which is producing the majority of the renewable energy it uses itself, after refurbishment will be producing more energy than it actually needs.

EU-GUGLE: Smart Cities. FP7 

Coordinated by CENER, it is the most ambitious energy refurbishment project that currently exists in Europe. Its objective is the retrofitting of 6 districts in 6 European cities (Milan, Bratislava, Vienna, Tampere, Aachen and Sestao) towards the nearly zero energy building standard- NZEB.

Policies to ENforce the TRAnsition to Nearly Zero-Energy buildings in Europe-Intelligent Energy Europe

The objective of the ENTRANZE project is to actively support policy making by providing the required data, analysis and guidelines to achieve a fast and strong penetration of nZEB and RES-H/C within the existing national building stocks.

PAES – TOOL Project – Government of Navarre 

The objective of the project is to develop a simplified web support tool that will enable the design and management of Sustainable Energy Action Plans (PAES) in a municipality, above all, taking the small municipalities (less than 10,000 inhabitants) into account.

RENAISSANCE – Concerto Project of Zaragoza 

Construction of 900 bioclimatic flats in Valdespartera and energy and environmental rehabilitation of 600 flats in the neighbourhood of El Picarral. CENER has developed a methodology for bioclimatic rehabilitation. Led by Zaragoza City Council, the European partners are the councils of Lyon (FR) and Milan (IT).


Energy rehabilitation of 120 flats in the neighbourhood of Lourdes in Tudela (Navarra), including the installation of a district heating network fuelled by biomass, and the construction of 150 bioclimatic flats in the neighbourhood of Queiles, also in Tudela.


Construction of 900 bioclimatic houses in Valdespartera and the energy and environmental rehabilitation of 600 houses in the El Picarral district.

Saguaro (2005)/Rockwool International Project

The aim is to analyse the impact represented by the increase in insulation in new buildings, in energy saving terms, as well as the associated reductions of CO2. The study assesses the entire national territory, both on a local level and in large cities.

Design, construction and monitoring of a solar chimney (2004-2006)/ Ministry of Education and Science

The objective of this project is to obtain an optimised design of a solar chimney as a passive natural ventilation system applied to blocks of flats, aiming to achieve a modular prototype that will be easily adaptable to different types of buildings.
