We work on all types of buildings: schools and universities, nurseries, housing, student residences, sports and leisure facilities, cultural facilities, health and social facilities, offices and business parks, etc.
Convinced that the environmental issue is central from the very beginning of the project, we are a driving force and are present with the team at each stage of the design. Participation in meetings and iterative exchanges with all the project's stakeholders allow us to specify our approach and to engage the right studies at the right time.
Responding to the needs of the project by favouring the search for new solutions, questioning habits and the regulatory framework, sometimes outside the norm.
Our missions include the following expertise:
We mobilize advanced tools for comfort modeling, thermal and aeraulic simulation, necessary for the design outside the standards of the thermal and environmental regulations.
Our tools: Comfie Pléiades, TRNsys, TRNFlow, Design Builder/Energie Plus, Virtual Environment, SimScale
Faced with the increasingly important issues related to climate change, summer comfort is becoming essential in the design of buildings. We optimize buildings to avoid the use of air conditioning systems by deploying alternative approaches to comfort beyond the simple temperature parameter.
We design and dimension natural ventilation systems to ensure the air renewal of buildings. This non-standard technique mobilizes the natural pressure differences of the air to ensure air quality without the use of fans, which consume electricity.
TRIBU has been present in Reunion Island and Mayotte for the past fifteen years and has taken part in the remarkable laboratory that Reunion Island represents in terms of sustainable buildings adapted to the tropical climate. Many projects are currently being studied in Mayotte.
The bioclimatic approach in a humid tropical climate begins at the plot level and even at the urban planning level, with a strong vegetation of the immediate environment of the building.
Wind modeling completes the work on the vegetation of the site. The simulations of the exterior airflow allow the optimization of the thermal comfort of the users. Ventilation and natural cooling are two key elements of tropical bioclimatic.
Low-nuisance construction site and environmental quality monitoring
We draw up a low-hazard worksite charter with the aim of defining the requirements, means, responsibilities and methodology to be implemented by the companies to guarantee respect for the human and natural environment: management of worksite noise and dust, pollution prevention, health of workers, impact on biodiversity.
Our actions on a low-nuisance construction site:
Prior to the construction site, we discuss and accompany the companies in the implementation of the low-nuisance construction site charter.
During the construction phase, we monitor and verify compliance with the low-hazard construction site charter (e.g., waste sorting, monitoring of energy consumption, worker awareness, etc.).
An environmental assessment of the low-nuisance construction site is carried out at the reception of the site.
This low-nuisance construction site approach applies to new construction as well as to rehabilitation and deconstruction operations.
We are involved in the construction phases to guarantee the proper implementation of the environmental quality elaborated in the design phase and to accompany the construction actors in a respectful logic of the construction phase.
The quality of implementation conditions the achievement of the environmental and energy performances defined during the design phase. We have a rigorous methodology of follow-up of the building site based on the validation of the execution documents (technical sheets, calculation notes, plans...), the conformity of the materials and the quality of implementation during regular visits of the building site. We have at our disposal a large database of references of materials, details and technical and architectural solutions. We also share our know-how on airtightness, by raising the awareness of companies, by assisting them in the identification and development of technical details, and finally by conducting air permeability tests. At the end of the construction site, we participate in the operations prior to the acceptance and commissioning of the building in order to ensure the proper functioning of the installations. We accompany, inform and sensitize the users and managers on the operation of the building and the maintenance through meetings and communication tools (welcome booklet, posters, maintenance ...).
Diagnosis resources and reuse
At a time when resources are running out, it is necessary to study the possibilities of reusing products and materials in order to limit grey energy and to limit the extraction of raw materials necessary for the realization of construction and renovation projects. From the sketch phase to the construction site, TRIBU is attentive to the presence of local deposits that can be used for reuse. TRIBU applies the 3R methodology (Reuse, Rejuvenation and Recycling) in a logic of circular economy and energy sobriety. We make the market parts open to the integration of reused materials. TRIBU has also participated in the realization of the MOOC reuse
This approach is approached with the objective of reuse, re-employment of materials and equipment to imitate the impact of the project. The resources diagnosis is translated by an inventory and a characterization of the products, materials and equipments so that the products and materials are reused on site and integrated from the design phases of the project or integrated in a field of valorization ex-situ.
In order to improve the reuse or the reutilization, we carry out meticulous site visits in order to establish recommendations to reuse materials or equipment on site. We also propose a disposal booklet for ex-situ reuse.
Local resources and biosourced and geosourced materials
Geosourced and biosourced materials are numerous on the French territory: straw, wood, hemp, cellulose wadding, raw earth, adobe... Their implementation limits greenhouse gas emissions and stores carbon throughout their life and plays a role in the thermal comfort of users. To best integrate them into projects,
Labels and certifications aim to guarantee the environmental quality of buildings. We participated in the construction of the HQE approach, but we have moved away from this approach that is too "standardizing".
We master the different existing solutions in France and abroad. Therefore, we advise the clients on the most coherent choice.
BBCA, local standards: BDF, BDM, BDO, Overseas, NF HQE sustainable building, E+C- label, Breeam, Leed, Well, Passivhaus, Bepos, Biosourced label
We assist the client in choosing an ambitious sustainable development strategy, adapted to the site, the program and the budget of the operation.
We systematically carry out an energy and environmental feasibility study in order to set objectives consistent with the site, the climate and the economic constraints.
Our approach and our documents pay particular attention to raising the awareness of the actors to environmental issues.
Our missions :
We set up sustainable development strategies within companies (inventory of fixtures, priorities for action, setting up of specifications) .... We develop operational tools customized to the operator's way of doing things.
We are convinced that the commitment in the approach requires the rise in competence of all the operators. Our pedagogical approach tends to propose a framework that encourages the participation of the actors.
