Lowered electricity coefficient in the DPE: a threat to energy renovation
Summary for decision-makers
Summary for decision-makers
FILMM, the trade association representing manufacturers of mineral wool insulation, is warning about the reform of the DPE calculation planned for January 2026. This measure, which lowers the primary energy coefficient for electricity, would reclassify 850,000 homes without renovation, giving a false picture of the French housing stock.
According to FILMM, this reform risks slowing down energy renovation, worsening the precarious situation of poorly insulated households, and weakening a key industrial sector. It also calls into question compliance with the European directive on the energy performance of buildings. FILMM calls for the reform to be suspended and for dialogue to be reopened with the stakeholders involved.
The Government has announced a further reduction in the primary energy coefficient (PEC) of electricity in the calculation of the DPE, dropping from 2,3 to 1,9 from January 2026.
850 thermal strainers erased without work: FILMM sounds the alarm
Behind what is presented as a technical adjustment lies a measure with far-reaching consequences. FILMM – the national union of manufacturers of manufactured mineral wool insulation – denounces the artificial reclassification of 850 thermal strainers, without any work, which distorts the energy reality of the French housing stock.
This reform could significantly slow the momentum for efficient renovations, fuel the installation of inefficient heating systems, and weaken an industrial sector committed to the ecological transition. It also raises questions about its compliance with the European directive on the energy performance of buildings. FILMM calls for this unilateral decision to be suspended and for dialogue with stakeholders to be resumed.
FILMM, the national union of manufacturers of manufactured mineral wool insulation, is concerned about the harmful effects of the reduction in the primary energy coefficient of electricity in the calculation of the DPE, planned for January 2026. Presented as a simple technical adjustment, this measure could reclassify 850 homes currently classified as thermal sieves... without any work being carried out on them.
By giving an artificially flattering image of the electrically heated housing stock, this reform risks slowing down the momentum of energy renovation, worsening the precariousness of poorly insulated households, and weakening a French industrial sector that is nevertheless committed to the ecological transition.
The consequences are multiple: loss of credibility of the DPE, incentive to install inefficient heating systems, drop in demand for insulation and jeopardy of major industrial investments made in the region.
Beyond national issues, this reform also raises questions about its compatibility with the European directive on the energy performance of buildings (EPBD), which imposes a clear and coherent trajectory at the level of the Union.
Faced with this risk of circumventing climate and social objectives, FILMM calls for the immediate suspension of this reform and the opening of a transparent dialogue with all stakeholders.
Frequently Asked Questions for Decision Makers
What is the impact of the decrease in the primary energy coefficient of electricity on the DPE?
The planned reduction in the primary energy coefficient for electricity, scheduled for January 2026, will lead to the reclassification of approximately 850,000 energy-inefficient buildings without any actual renovation work. This measure presents an artificially improved image of the housing stock heated by electricity.
What risks does this reform pose to the industrial sector and energy renovation?
The reform risks slowing down high-performance renovations, weakening the insulation industry, and encouraging the installation of inefficient heating systems. It could also lead to a decrease in demand for insulation manufactured in France.
Is the reform compliant with the European directive on the energy performance of buildings?
The compliance of this reform with the European directive on the energy performance of buildings is being questioned. It could, in fact, hinder the achievement of climate and social objectives set at the European level.
