When and where
The 8th of February 2018 the association P2E organised a workshop in Paris to show the progress made on the energy renovation building passport.
What, profile of the attendees
Expérience P2E (www.experience-p2e.org) is an association on the energy renovation of housing. In partnership with industry players (e.g. Saint Gobain, Schneider Electric, EDF), territories / local players (e.g. Région Grand Est, Anger Loire Metropole) and other initiatives (e.g. Effinergie, the shift Project, Qualitel) wishing to make a success of their energy transition, the P2E experiment launched at the end of 2016, and for an initial duration of 18 months, the experimentation of an Energy Efficiency Passport (P2E) aimed at to support households in their housing improvement projects.
Feedback from the presentation
The P2E (Passeport Efficacité Energetique” propose the following solutions:
- 01 – be collaborative: allow all actors of the building sector and building value chain access to the technical data of the building;
- 02- be complete: characterize the potential of improvement and propose detailed and specified recommendations to reach the nzeb level at the end of the renovation process;
- 03 – be pedagogue: take into account the user needs, their budget, the technical constrains;
- 04- be dynamique : follow the energy refurbishment step by step;
- 05-be evolutive : be complementary to existing tools, procedures and initiatives and add new functionalities answering the needs of the building actors.
It is identified that the upgrade of energy efficiency of the building is very often not the initial motivation of the building owner when undertaking the refurbishment. Therefore P2E intends to embed energy renovation at trigger points of building renovation (e.g. change of building owner) in two different ways:
- one step refurbishment;
- step by step refurbishment.
To establish a P2E passport for a single family house should not take longer than ½ day including a 2h visit. Therefore the methodology to determine the refurbishment solution are based on a pre-calculated combinations of refurbishments packages tacking into account also lifespan and identified problems during the visit (e.g. moisture). The P2E procedure is compared to healthcare: first ask a generalist (P2E) and if needed consult a specialist. The cost for a P2E passport are estimated at 400 €. Building owners are willing to pay 100 €.
- Experiences from other passport initiatives in Europe
Several “Passports” are currently being tested in Europe. In one session, experiences from other passport initiatives in Europe were presented (the German iSFP project, the H2020 iBROAD project).
Hereafter the template for the roadmap of the German iSFP project is presented.
Céline Carré, President of EuroAce,– Head of European Public Affairs, Saint-Gobain showed how the Building passport are reflected in the new energy performance directive for buildings (EPBD).
Relevance, comparison with ALDREN
The general approach is comparable to ALDREN. The P2E solutions are well structured and underline that the approach must be larger than only technical. The technical approach (pre-calculated renovation packages) could be an example to identify the ALDREN step by step solution (task 2.6.3). This approach is also be planned to be used in the H2020 STUNNING project. The strong point of the P2E seems to be the cooperation with the target groups (see before) and especially with local initiatives.
It is important to take into account the already existing building energy “ecosystem” and to distinguish well the different notions. In general the following notions are used (a proposed definitions is added).
- “logbook” (in French carnet numerique) is containing all relevant building data. In France where the logbook will be mandatory in 2020 it has three objectives: a) to inform about the use of the building, b) to inform about the maintenance of the building, b) to provide information about possible step by step upgrading. In ALDREN we call the logbook data model (task 2.6.2 see figure hereafter) and the three objectives are taken into account in the “services” (see hereafter).
In France several logbooks have been already worked out and selected by the authorities.
- “EPC” is considered as a diagnostic at a given moment in the building life. Recommendations are provided, but in generally not structured step by step. In ALDREN we call it EVCS (task 2.2)
- “Building Audits” in the Energy Service Directive building audits are associated to EPC,
- “Building passport” may be considered as an EPC but with a structured roadmap (one step, or step by step) towards the nzeb level. In ALDREN we call it also building passport (task 2.6.3). In this roadmap should be some “milestone” which were not yet defined in ALDREN.
P2E is clearly focusing on the building passport understood as roadmap. Neither the indicators nor the template used for it were presented in the conference.
During the last TELCO on ALDREN task 2.6 the following definitions were proposed (see hereafter figure on the left). In ALDREN the building passport and the EVCS are “services” (see figure on the right).
The ALDREN (ALliance for Deep RENovation in buildings) project has received funding from the Europe Union’s Horizon 2020 research and innovation programme under grant agreement No 754159.
