Number of professionals believe that the new environmental standard for new housing will greatly increase pressure on prices. Unfounded fears, according to the executive, which puts on the learning effect.

A new environmental regulation, named “RE2020”, applies to new housing since January. The goal: to force the promoters to build greener buildings, with the abandonment of oil boilers, coal and gas in these new constructions.
Summer comfort and carbon weight must be taken into account in the development of each apartment or house. Just like the energy optimization of the building as a whole, through a better orientation, the recourse to wood, etc.
Some promoters did not wait for this entry into force to test new construction methods. “Our first experiments go back to 2015”, reports Catherine Poulicen, CRS Director and Crédit Agricole Real Estate innovation. “We work with biosourced materials, such as wood, but also the integration of new insulators, such as hemp, which makes it possible to reach a better quality of the air and is a very good thermal and phonic insulation.” ”
Hemp and Bioclimatic Veryle
To do this, the promoter cultivates, since 2019 and until 2022, nearly ten hectares of hemp in Melun (Seine-et-Marne), in the future ecoquartier Woodi. In partnership with Wall’UP, manufacturer of hemp concrete walls, this constructive mode will be used on an operation mixing apartments and townhouses, which must be delivered in 2025, and, futures, in nearly 2,700 homes, so only public infrastructures.
“On summer comfort, we tried an experience in Blagnac, near Toulouse, creating a bioclimatic verse. Thanks to its natural ventilation system, it offers residence inhabitants a lower temperature temperature Outdoor. The difference sometimes reaches 10 degrees “, pursues M me pouliquen.
COGEDIM, for its part, relies on ten commitments to deliver more comfortable and efficient apartments. On the program: Better air quality, an optimized design to limit the heat sensation in the summer, glass surfaces greater than 20% (to have more natural light in the housing), or showers and showers and W.-C. equipped with systems reducing consumption.
“The first dwellings that will meet all these standards will be delivered within a year and a half,” says Vincent Ego, General Manager of COGEDIM. “With this specifications, we are already ready for RE2020. Certainly, these innovations involve an increase in the cost of construction. But since we have been experimenting for several years, we manage to absorb the additional cost to deliver more efficient housing without being more expensive, “he says.
