As part of a roundtable organized during BIM World on April 5 in Paris on the topic “Low-Carbon and Existing Assets: What Solutions?” “, Norbert Fanchon, president of the Gambetta group, gave several paths to follow so that promoters can make their revolution. Selected excerpts from this event, also attended by Marc Guedou, President of the Promoter Groupe Pierre Étoile, Valerie Mancret-Taylor, CEO of ANAH, and Yolene Pofichet, Member of the National Council of the Order of Architects (CNOA).

Our job as promoters is to manage opposites: we must stop artificiallycarry out operations to revitalize the territories, increase home ownershipwhile we are getting fewer and fewer building permits, especially when it comes to building R+5 or R+6 said Norbert Fanchon, president of development company Groupe Gambetta.

Before adding: At the same time we must reduce the energy consumption of buildings and we are left with less and less money to do our work. Social landlords drained of 1.3 billion euros a year by the previous government, and we can imagine that this is not the end. Moreover, all the evolutions of tax exemption systems for individuals show that the state has less and less desire to invest money. »

These different imperatives should lead to reflection on the role of promoters, as well as the way they operate, he says. ” Our profession must make its revolution on the principle that if we are to rebuild a city upon a city, we must imagine the city of tomorrow. It goes through building restoration, but not only. We can too use new biomaterials : damp earth, wood, hemp straw … But to do this, you have to pay for it, making housing affordable for the French. »

“So you have to accept height and a new form of density. This needs to be demolished. I wish I could say that elevation is a decision, but today it is very poorly accepted “, he continued. For him, decarbonization starts first and foremost with the right use of land resources. “By putting housing in the right place, we already avoid forcing people to travel by car.”

“Our duty is to build a city within a city” (Marc Guedou, Groupe Pierre Étoile)

Marc Gedoux, President of the Pierre Étoile Group and Vice President of Promoteurs du Grand Paris, confirmed this observation regarding the development of his profession. ” As promoters, we are used to doing something new. But our duty is to make more and more city after city. We are particularly confronted with the restructuring of buildings. This is the case, for example, with buildings from the 1970s that need to be converted into housing.

“I mean a major operation in a 30,000 m² dormant office building.2 at the foot of the Gare Saint-Quentin-en-Yvelines. Our task was to build 150 housing units. We have encountered a technical impossibility regarding residential-specific standards that are different from office standards. It was impossible for us to achieve a retreat, so much so that we had to demolish the building (keeping the infrastructure that was not limited by these standards) in order to build behind it. It was heartbreaking. »

For group president Pierre Étoile, elevation represents a viable operation for urban centers. ” This is very beneficial, firstly, because it is often made of a wooden frame for reasons of weight, i.e. low-carbon material, and they insulate the roof of buildings, which is the 1st heat loss zone of buildings. »

“The ALUR Act has made it easier to make decisions about expanding fractional ownership by establishing majority rule. Finally, façades tend to beautify buildings and give them a youthful appearance. On the other hand, for us, the promoters, these are auxiliary operations, since they are often quite small. “, According to him.

“Challenges of the 21stand century: saving resources” (Valery Mancre-Taylor, ANAH)

Valerie Mancret-Taylor, CEO of the National Housing Agency: challenges on the 21stand century, in terms of development, urban planning and, consequently, housing policy, is to save resources (soil, energy, etc.).

“To do this, you need to remember that 80% of the homes we will be living in in 2050 already exist. Of course, there will be an offer of new housing, but the work of restoring and beautifying what is there is of central importance in the coming years. This is what is called the factory of the city on itself. It is necessary to open up new lands for urbanization as little as possible, so it is necessary to work on the existing heritage. »

“Another goal is to decarbonize our buildings, as we are reminded by the publication of the latest IPCC report. Therefore, it is necessary to improve these dwellings and allow them to receive energy with the lowest possible carbon content. »

These issues were partly mentioned in the Climate and Sustainability Act, which was voted on in the summer of 2021. Two elements should draw our attention: the energy renewal obligation for landlords who rent energy-intensive private sector housing on a very close calendar, and the resulting obligation to support households. There are about 5 million energy sieves in the country. Therefore, it will take several years and a lot of support to achieve these goals. “, she added.

In this case, she reverts to the various possibilities offered by ANAH:

  • household help, whatever their means, carry out energy renovations in their homes, paying them subsidies to finance part of the work done in their homes (eg MaPrimeRénov’). Over the past 10 years, home improvement rates and, in particular, energy renewal have increased, of course, under the influence of aid, but also thanks to public awareness”;
  • from support of local authorities to implement these local policies to repair and improve housing in the territories. There are currently about 800 programs contracted with local governments, and they are increasingly mobilizing to implement this type of housing policy that advocates interfering with what already exists”;
  • “devices that allow us to fund state and semi-state players in the improvement of entire buildings (real estate and land intervention system). These are devices that are still little known because they are very recent, but which are gradually growing in the territories. They give very significant results. It also allows for social inclusion, which is important in tough markets”;
  • tax help : Denormandie in the old, Loc’Avantages… »

She clarifies that there are other mechanisms at the territorial level, most notably the Action Cœur de ville and Small Towns of Tomorrow programs piloted by the National Agency for Territorial Unity. ” They allow dealing with both housing and equipment, services in the city and the complementarity of the centers of the existing city. »

“We are helping to decarbonise what already exists” (Joline Paufische, CNOA)

According to Yoline Paufische, member of the National Council of the Order of Architects (CNOA), responsible for environmental action, the profession of architect also plays an important role in creating the city of tomorrow, starting with the city itself. exists today.

30,000 architects in France take care of the construction of the city as well as its renovation. They are already present in the areas to be rehabilitated in an innovative way. Today, as part of an energy audit, a number of architects are working on energy issues in particular, with design bureaus and companies in search of new building methods: materials from bio-resources, reuse of materials after demolition… We help to decarbonize existing “, she said.

According to her, a few levers would speed up the movement. ” The main parameter is the analysis of the existing tissue. Early diagnosis is essential to achieve energy savings. Other levers PLU: may need to be modified to facilitate height operations. »
