Project
Objectives
COLEOPTER develops an integrated approach of energy renovation of public buildings, linking technical, social and economic challenges.
The project aims at leading a territorial dialogue with the local stakeholders to jointly build a renovation working plan to renovate a public building. A new water-energy nexus audit methodology will be developed to enhance efficiency gains.
The use of BIM as a collaborative tool facilitates dialogue (experts/non experts) around a 3D model of buildings. This tool will be tested in pilot projects in Cartagena (Es), Combraille (Fr) and Póvoa de Lanhoso (Pt) and will be replicated buildings in Andorra to validate transferability.
This approach was designed to respond to Sudoe challenges: increasing awareness through dialogue on a reference building to massify renewal rates, analysis of energy and water efficiency and the dissemination of collaborative BIM tools.
Total eligible cost: 1.454.944,07€
ERDF budget: 1.091.208,06€
Activities
1. Contextualization, prefiguration and dimensioning of the COLEOPTER approach in the experimentation territories (pilot cases)
Examples of integrated approaches to energy efficient buildings will be collected in Sudoe and, particularly, in the three implementation regions, capitalizing on existing experiences and identifying funding opportunities. A circular economics study will also be developed to identify local materials and their characteristics.
We will look for proof of concept of an innovative methodology to conduct water-energy audits, which will be implemented in the pilot buildings to be renovated. The pilot building to be built from scratch will consider the water-energy nexus during the construction phase and assess its water-energy efficiency index after construction.
This activity will later define the conditions to replicate the approach of the demonstration areas to the rest of Sudoe.
2. Development of the territorial dialogue and building of cooperation channels
The territorial dialogue process will be carried out in 4 stages:
- Organisation of an event in each territory, with the main stakeholders, to reach the local population and involve them in the definition and implementation of the dialogue;
- Partners’ qualification on carrying out territorial dialogue. During this training, partners will work together to develop a process adapted to the three scenarios on how to conduct the dialogue (shared structure);
- The process structure is proposed to the local monitoring committees, which will use it as a basis to co-build local processes for carrying out the dialogue;
- After testing and validating (or adjusting) these local processes, a second training session is held, during which a replicable methodology is developed for conducting the territorial dialogue on energy efficiency in public buildings.
3. Implementation of BIM as collaborative platform in the local ecosystems of stakeholders to federate around the dialogue
3D BIM models will be developed at each pilot site, which will be implemented on a collaborative platform, so that all information on the project, construction and management of buildings is available on a single platform, which will allow viewing, in 3D and online, any point of the building.
In order to carry out transnational exchanges using the collaborative platform, training sessions will be given to partners, and information to stakeholders that are part of the territorial dialogues, in order to facilitate their contribution to participatory work plans. Training sessions will also be open to associate partners, in order to democratize the use of BIM among SMEs in the experimentation territories.
Local partners will be involved to moderate the use of BIM in the territorial dialogue process.
4. Conduct of renovation work in the four demonstrator buildings based on the results of participatory processes and water-energy nexus audits, with a continued involvement of all stakeholders
Based on the recommendations developed through the participatory processes, the collaborative work plans on the BIM platform and the elements of improvement identified through the water-energy audits, the technical project is constructed, the work plans are validated and work is carried out on the pilot buildings, with two goals:
- Maximize the decrease in energy consumption of buildings, including, when possible, reaching nearly zero-energy buildings (through exemplary rehabilitation work and the rational use of energy and water related to daily activities in buildings);
- Set an example for other refurbishment/construction projects in the territory and raise awareness of the challenges of energy efficiency.
While rehabilitation works are carried out in the three existing buildings (Cartagena, Póvoa de Lanhoso and Combraille) and the works of the 4th building (Est Creuse), the monitoring committees for each building, defined through the dialogue process, will meet to ensure mobilization in the event of unexpected developments and to monitor the progress of the work carried out.
After intervention in the pilot buildings, new water-energy nexus audits will be carried out, using the methodology developed for comparison with the initial state.
5. Definition of conditions for success, capitalization and diffusion of results, and replicability of the COLEOPTER approach in Andorra
Definition of the conditions for replicating the COLEOPTER approach, using the typology of rural areas, the methodological steps to carry out energy and water audits, the participatory processes implemented in the pilot buildings and the guidelines on the use of BIM and the first results of the pilot buildings.
Conducting a comparative analysis of the processes designed to the measure, to validate the replicability of the approach and define the conditions of success for this transferability, including: impacts on energy profiles, mobilization and type of buildings to be considered. The replicability of the approach will be validated by the implementation in Andorra.
