When architects apply RE2020 in the higher education sector

We all know that RE2020 has disrupted certain habits. Indeed, we owe to this regulation, among other things, the spread of bioclimatic design of buildings and the use of low-carbon bio-sourced materials. Architects realize their important role in implementing RE2020, and are doing their best to find the right balance between ventilation, heating, lighting and materials. Batweb caught up with some professionals who gave us their impressions.

It is part of ongoing and progressive work in favor of less energy consuming buildings, and RE2020 also relates to the third sector. A large number of architects we met support this regulation. They are interested in optimizing the energy design of the building, reducing the primary energy consumption but also the impact of the building components, as well as various researches related to the discomforts encountered in the summer period. . Many fears have been implemented.

Complex for some, challenging for others

The RE2020 decree on the third sector, according to some architects, “ Too premature “In fact, many small structures are not prepared and some architects do not necessarily master this subject. Despite everything, most professionals recognize the necessity of taking this into consideration and applying it.

We contacted architects Clémence Saubot and Baptiste Rouit from the SRA Architects agency team based in Châtillon. They declare: “ For us, who are used to implementing ambitious and large-scale projects, this represents a huge challenge. » In fact, the agency has long been considering using more compact, efficient, and less consumable envelopes. ” At the SRA, we are lucky and have always had support, and we are constantly questioning the boundaries », emphasized the architects. This could explain the agency’s flexibility in considering all these issues, starting with the feasibility of the project. The architects add that within the SRA, they are in the process of launching an internship, and since the agency often works in partnership with foreign architectural agencies, it is necessary to master the latest regulations to be able to move forward better. ” Foreign agencies are curious to work this way by applying new French rules that they do not apply at home », select architects.

I am in the house of Art Charpentier, we are close to the architects Raquel Milagres, Carole Azzi and Guillaume Delfesc who are pleased that the age is due to apply to RE2020 and the previous design, they will receive a favorable response to these changes that are not not easy. In fact, within the agency where there is a very good understanding, exchanges take place between collaborators so that all projects progress together in a collective and collective spirit. ” When RE2020 and the Higher Education Decree were issued, the agency wanted to train everyone “, specifies Raquel Milagres.

For his part, Thomas Richez, founder of Richez & Associés, says that this is a complex topic because the idea of ​​“ consumption » It can change according to user behavior.

RE2020 and the role of the architect

With RE2020 in relation to the third sector, architects are directly concerned. Minimizing the carbon footprint, considering the best building orientation, thinking about the building form and cohesion, and deciding on the spread of the building are key questions that need to be addressed according to SRA Architects. Sufficient answers. ” We find ourselves responsible for issues that have largely been delegated to engineers “, declares Baptiste Rouet. Indeed, it is reasonable to ask whether the role of the architect, with all these regulations requiring more and more technical knowledge, will not change fundamentally? Everyone agrees that the practice of architecture has continued to evolve. She explains Raquel Milagres said that since the 2000s, and especially since 2005, the organizational chart of the project has undergone many changes.” Before the architect was the leader », adds Carol Azzi, of Arte Charpentier. ” Today, it must cope with thermal, energy and environmental requirements, while ensuring the production of a reasonable structure. “. Other professionals feel the same concerns and define the architectural project as a global achievement and not just a response to some decrees. It is therefore an impossible task for some and very difficult for others. That is why, according to many specialists, changes must take place within the architectural agencies themselves but also at the level Those responsible for regulations.” This is continuing education “, concludes Raquel Milagres.

Towards new materials?

Especially materials that consume less, according to some architects. This is possible through research and the ability of a few manufacturers to generate a large number of elements suitable for use at an industrial level. While a certain number of architects advocate building entirely in wood, others are more precise and propose mixed solutions. At Arte Charpentier for example, architects are made aware of the use of “ The right material in the right place “Moreover, the agency has just delivered a new mixed project using wood and concrete and is in the process of completing another rehabilitation and expansion project where using metal to reinforce wood and concrete is the most logical solution. But is there a low-carbon metal? The architects answer that there are already suppliers. Two on the market The financial cost of the project as well as its environmental cost is a criterion that must be taken into account from the beginning, hence the importance of training and mastering the regulations.

Furthermore, according to SRA engineers, “ RE2020 is complex for small structures but the challenge is great, the architect’s profession will evolve especially when new constructions and materials are scarce, and it is exciting to find alternatives. “So, in their R&D part, architects are constantly asking this question: How to go from a brick facade to an extension and apply it to an industrial or large-scale project? Reaching the RE2020 threshold is certainly difficult, but the agency realizes that it must Commit to doing this.” We will research new processes and find materials that meet the required carbon footprint but are manufactured in large quantities », Add the architects who have just implemented their first mixed project in Paris. ” Today we are exploring wood in the tertiary sector, and we have implemented a mixed project in wood and concrete, which is the first experience for the agency that used to work mainly with concrete. “But the main topic remains the height of the ceiling in offices, without mentioning the acoustic problems and the mentality of the instigators or users of the change. It is a qualitative shift according to the architects. But there is one thing that is not understood,” The Paris Police, through the Wood Doctrine, have placed reservations on exposed wood and its packaging to better respond to security issues, which means increasing their carbon footprint. », add the last.

Thus, many architects are waiting to see RE2020 develop in the higher education sector, which, in their opinion, conflicts with some regulations. Architect Thomas Reches, who shares this view, has just signed a collective forum that points out fire regulations that, according to more than 600 signatories, put low-carbon construction at risk. Excessive regulation kills organization? However, this seems to deviate significantly from the intended goal. Unless changes occur and developments occur.
