The Profeel program, funded by the CEEs and piloted by the Agence Qualité Construction (AQC) and the CSTB, aims to create tools and methods to improve the energy performance of buildings. Philippe Estingoy, General Manager of AQC, reviews the various projects created within the framework of Profeel and reveals the main areas of work of Profeel 2.

Can you tell us about the program Professional ?
Philippe Estingoy – Within the framework of the Grenelle de l’environnement, ambitious objectives had been set for buildings, with energy and environmental requirements and a need to improve the performance of buildings. A first program, entitled “Rules of the art Grenelle of the environment” (RAGE), aimed to work on the technical and scientific levers that can improve the technicality and performance of the materials used. The second program, entitled PACTE, continued productions as an extension of RAGE, with, in addition, tools for the training of building stakeholders, the dissemination of feedback, “popularization” documents, measurement tools. The third program, Profeel, financed by the Energy Savings Certificates (EEC) has widened the scope of action with two major axes: to make clients want to embark on a renovation operation and to create confidence between prime contractors and engineering companies. Profeel ended on December 31st.

What are the main projects resulting from the Profeel program?
PE – On the first part, which consists of helping to trigger effective work, I can cite several variations: Go Renove brings together databases which, processed using artificial intelligence, provide areas for improvement by type of building. It includes specific tools for social landlords. RenoStandardstems from the same desire by delivering a few references for renovation solutions. In a toolbox, we have given examples of the Densify and Renovate approach. Other resources, a guide to “low-tech” including the publication of a comic strip and a series of podcasts. On the second part, focused on issues of trust, we have developed self-checking sheets for construction companies and work acceptance sheets. To date, more than 100,000 sheets have been downloaded. We have also developed an application, Check’Reno which includes all of these files, as well as design assistance tools, in particular PAC’Reno for the sizing of heat pumps and Conduits’Renofor the design of flues.

Can you briefly come back to the Sereine project?
EP- Sereine is a project for measuring the intrinsic energy performance of construction. It is a device for measuring the performance of the envelope and equipment integrating metrology inside and outside the building, combined with ventilation and heating. We succeeded in reducing the measurement time to 24 hours for houses insulated on the inside and 48 hours for houses insulated on the outside, whereas the existing European protocol provides for 21 days.

What are your projects and news for the coming year?
EP- Following Profeel, we launched Profeel 2, which follows up on the approach. We have developed complementary services, in particular Quartet to improve the sanitary, thermal and acoustic comfort of renovated buildings and RestaurEval to develop innovative technical solutions dedicated to global renovations. We have consolidated what has been produced and developed, with Go Rénove 2 and Sereine 2. Finally, we have developed new tools, such as Interface, which will explain the measures to be taken to deal with the interface between the construction parts of the various building trades, or even Rénoptim, which aims to find levers to curb air conditioning consumption by improving summer comfort. The Profeel 2 program will deliver its conclusions at the end of 2024.
