The Tectoniques ingénieurs team is very pleased to welcome eight new partners : Mathilde Abbes structural engineer, Lara Brayelle HVAC engineer, Louise Chretien structural engineer, Louis Giraud construction economist, Cécile Luthéreau HVAC engineer, Nathanael Soubeyran construction economist, Antoine Schaeffer electrical engineer and Naouras Nsiri in electrical engineering internship.
They enable us to extend and consolidate our skills in new constructive and environmental solutions.
Specialized in dry construction, bio-sourced and geo-sourced development, and focused on low carbon objectives, the Tectoniques group offers a multi-business platform committed to innovation, from two offices in Lyon and Bordeaux.
Built in Charbonnières in the Rhône, the program is composed of two spaces: in the North the Maison des jeunes and in the South the Maison des Arts, for a total surface of 1200m².
The energy hub consists of a 52 kW condensing boiler coupled to a 41 kW gas absorption heat pump, itself associated with three vertical geothermal piles 120 metres deep.
This heat production is distributed in different circuits: AHU, floor-to-floor circuit, radiant panels and terminal units according to different water regimes.
The gas absorption geothermal heat pump solution is both the most innovative and the most environmentally efficient solution:
– The primary energy balance of gas geothermal energy achieves the best ranking compared to all the other solutions studied (condensing gas boiler, wood boiler, electric heat pump),
– The number of geothermal probes to be installed in the ground is reduced by half compared to an electric heat pump solution, resulting in a limited overall cost,
– The solution allows to do Geocooling (cooling in hot periods), by switching the heat pump. The major interest is to exploit the relative freshness of the ground at low cost (only the consumption of the 2 circulation pumps is taken into account to directly distribute the fresh water in the floor circuit).
This installation was remarkably carried out by the company BEALEM, which we salute for its professionalism.
Tectoniques ingénieurs recruits economists, HVAC engineers, civil engineers and electrical engineers. We are looking for partners who are convinced and committed to new constructive and environmental solutions.
We are in a phase of development and renewal, with beautiful projects for the immediate future but above all strategic objectives for the near future.
We specialize in dry process solutions, wood construction, bio-sourced and geo-sourced products, and more generally, we are committed to low carbon objectives.
Tectoniques offers a multi-business platform committed to innovation.
Located on the same premises, Arborescence structures bois and eEgénie environnement complement the skills of our two companies Tectoniques ingénieurs and Tectoniques architectes.
Technal and its manufacturer-installer SMMM have achieved a first in France with joinery made of recycled aluminium CIRCAL 75R.
Their post-consumer recycled content, equal to or higher than 75%, i.e. an average of 2.0 kg of CO2e/kg of aluminium, thus contributes to obtaining the Mediterranean Sustainable Building Gold (MDB) label.
They cover four public facilities in the Gavotte district of Les Pennes-Mirabeau, north of Marseille, built by the Tectoniques group: a 3,000 m2 media library, an intergenerational restaurant for 500 people, a school group with 15 classes and a children’s centre with a crèche and a Maternity Care Centre.
Tectoniques is currently working on a project for a school group heated and cooled in thalassothermics. Named Massileo and operated by Dalkia, the thalassothermal plant uses the Mediterranean Sea as a sustainable energy source to supply heat and cooling to the Euromed 2 urban project, an area of nearly 500,000 m2 in Marseille.
The plant emits 80% less C02 than a conventional installation.
The FMB facade consists of a load-bearing timber frame and a concrete outer skin. It is mechanically assembled using SSB connectors.
This process was developed by ICM structure and AIA studio bois.
We are going to implement an equivalent process on the housing operation on Grand Coeur in Nancy. The consultation file of the companies is in progress. This experience completes our previous wood-concrete facade operation carried out in Vaulx-en-Velin for the social landlord RSH. We had used the Farjot construction process, which is a more structurally interwoven device between wood and concrete. The FMB façade, on the other hand, provides a clearer interface between wood and concrete and is more in line with our current expectations. To be followed shortly on the construction site.
