There is no doubt that the thermal renovation of buildings, and in particular of energy-intensive housing known as “thermal sieves” will remain a priority issue. The Climate and Resilience Law of August 22, 2021 provides in particular for the gradual ban on the rental of “strainers” from 2023, 2025 and 2028, according to their Energy Performance Diagnosis (EPD) class.
It is clear that the constituencies represented by their new deputies are not equal according to their geographic location, the density of the population and the state of the more or less aging housing stock. Hellio, a key player in energy management, takes stock of the ten constituencies and their new deputies who have the most thermal sieves!
Methodology
The method of classifying the constituencies used uses the Demographic files on housing and individuals (Fidéli 2018), on the basis of the DPEs of 2017 and 2018 (old version before the reform), cross-checked with the interactive map of the DPEs of Ademe , and focuses on the rate of F and G housing on all housing by department.
This ranking is also illustrated by another indicator: the household energy vulnerability rate at the regional level. Energy vulnerability, also called energy poverty by the National Observatory of Energy Poverty (ONPE), is defined as "the fact of experiencing particular difficulties in one's home in obtaining the supply of energy necessary to satisfy one's needs. basic needs due to the inadequacy of its resources or its habitat conditions”.
This method made it possible to identify 10 districts which have the highest rate of dwellings classified F and G in the DPE. In order of classification: the two constituencies of Cantal, the constituency of Creuse, the two constituencies of Nièvre, the two constituencies of Haute-Loire and finally the first three constituencies of Vosges.
For Marina Offel, Hellio Public and Legal Affairs Manager: “Following this observation, the new deputies recently elected from the ten constituencies which have the most housing classified F and G in the DPE have five years to take part in the challenge of 700.000 renovations – global we hope – per year announced by Emmanuel Macron, in order to improve the quality of housing on their territory. The energy renovation of buildings is however hampered by the insufficiency and instability of financial aid to households and condominiums, the numerous regulatory changes, the difficulties of the work sector to recruit and train with the aim of promoting only global renovations and no longer by small gestures. The awareness and involvement of parliamentarians on these issues will be decisive!”
The Auvergne-Rhône-Alpes region at the top of the ranking of constituencies with the highest rate of "energy sieves"
At the top of the constituencies with the highest rate of housing classified F and G, according to the Demographic files on housing and individuals (Fidéli 2018) and on the basis of the DPE 2017 and 2018 from Ademe (old version before the reform ): the Cantal department has 47% of housing classified F and G by the DPE. This represents 27.600 dwellings out of a total of 59.121 dwellings. The low density of housing would also explain the high rate of housing classified F and G at the DPE.
On Ademe's interactive DPE map, housing classified F and G is mainly concentrated in the second constituency of Cantal, represented by MP Jean-Yves Bony, re-elected for a second legislature (LR).
The 2st constituency of Cantal, represented by Vincent Descoeur (LR), is in XNUMXnd position in the classification of classified accommodation F and G.
In 6th and 7th position of the 10 districts with the most energy sieves, two others are also located in the Auvergne-Rhône-Alpes region, the 2st and 43nd district of Haute-Loire (34.504), which list 92.304 dwellings classified F and G to ECD, out of a total of 37, or XNUMX%.
These constituencies are again represented by MP Isabelle Valentin (LR) re-elected in the 1st constituency of Haute-Loire and MP Jean-Pierre Vigier (LR) re-elected in the second constituency of the department.
It should be noted that all of these MPs, who have a high rate of F and G classified housing in their constituencies, must also be vigilant about the rate of energy vulnerability. Indeed, the Auvergne-Rhône-Alpes region, which includes the districts of Cantal and Haute-Loire, has 609.719 energy-vulnerable households on its territory, which represents 18,60% of households in the region.
If the dwellings classified F and G are not necessarily occupied by energy-vulnerable households, a certain number of them still occupy these dwellings. In fact, the fight against “thermal sieves” is an issue of social justice for these people. Newly elected officials have every interest in building their skills and analyzing data from their territory to meet the challenge of energy renovation.
The districts of Creuse, Nièvre and Vosges complete the ranking
The constituency of Creuse (23) is in 3rd position, the two constituencies of Nièvre (58) in 4th and 5th position and the three constituencies of Vosges (88) occupy the last three places in the ranking. These departments have respectively a rate of housing classified F and G of 44%, 41% and 33%.
Regarding the vulnerability rate, the districts of the Vosges department are located in the Grand-Est region, which lists 559.071 households in a situation of energy vulnerability, or approximately 24,30% of households in the region. For these households, the energy expenditure needed to heat their home and domestic hot water represents a high proportion of their income. For the year 2019, it is estimated that the average household energy expenditure was €1.602.
The new deputies elected: Catherine Couturier, NUPES – LFI (district of Creuse), Patrice Perrot, LR (2nd district of Nièvre), Perrine Goulet, Together – LREM (1st district of Nièvre), Stéphane Viry, LR (l st district of the Vosges), Christophe Naegelen, UDI (3rd district of the Vosges) and David Valence, Ensemble – PR (2nd district of the Vosges) are called upon to take into account the quality of housing and household life in their territory.
Focus on the capital: Paris, a very high number of energy sieves despite a relative rate of housing classified F and G at the DPE
According to the 2018 Fidéli survey and on the basis of Ademe's DPEs of 2017 and 2018, the Paris department comes in 8th position among the most energy-intensive departments. Compared to the other departments present in the previous ranking, the 75 counts a much larger number of colanders to renovate: 327.733 dwellings against 34.900 dwellings on average for the departments of the top 10. Out of a total of 1.062.232 dwellings, the share represents for as much as only 31% of the real estate stock of the city of Paris.
Faced with the dilapidated state of this housing stock, the planning rules and architectural constraints that apply to Haussmann-style buildings do not facilitate efficient and comprehensive renovations that would allow these dwellings to come out of energy class F or G. the problems of governance of the co-ownerships and the insufficiency of the financing granted to the works.
