Burgundy-Franche-Comté
Cities covered: Dijon, Besançon, Belfort, Chalon-sur-Saône
The region is predominantly in a continental climate (H1a/H1b), with harsh winters and significant temperature variations. Thermal studies and dynamic simulations incorporate enhanced requirements for the building envelope, thermal inertia, and thermal continuity.
Environmental project management assistance and support for the BDBFC (Sustainable Buildings of Burgundy-Franche-Comté) and QDBFC approaches, complementing HQE, BREEAM, NF Habitat HQE, and Effinature certifications.

Brittany
Cities covered: Rennes, Brest, Vannes, Quimper, Saint-Malo
Temperate oceanic climate (H2a), exposed to winds and salt humidity. RE2020 studies and dynamic simulations incorporate summer comfort management, control of wind-related heat loss, and the sustainability of HVAC systems in a marine environment.
Environmental project management assistance and support for the BDB (Sustainable Buildings Brittany) , where relevant, complement national environmental certifications.

Centre-Val de Loire
Cities covered: Orléans, Tours, Bourges, Chartres
The Centre-Val de Loire region is characterized by an intermediate climate (zone H2a) with significant temperature variations between winter and summer. Projects primarily involve multi-family housing, public facilities, and mixed-use developments on the urban periphery. The challenges focus on overall energy performance, summer comfort, and the optimization of HVAC systems in buildings of varying compactness. Our interventions guide technical choices during the design phase and ensure compliance with RE2020 and acoustic regulations.

Corsica
Cities covered: Ajaccio, Bastia
In Corsica, the Mediterranean climate necessitates a primary focus on summer comfort and solar energy management. Residential and hotel projects require thermal studies tailored to handle high summer loads. Our dynamic simulations and fluid dynamics studies optimize bioclimatic strategies and energy systems in this island environment.

Grand Est
Cities covered: Strasbourg, Metz, Nancy, Reims
The Grand Est region has a demanding continental climate (zones H1b to H1c), requiring increased attention to insulation, thermal continuity, and the performance of heating systems. Commercial and residential projects demand a rigorous technical approach from the preliminary design and detailed design phases. Our fluid dynamics and thermal studies, along with dynamic simulations, ensure sound energy choices and regulatory compliance in contrasting climatic contexts.

Hauts-de-France
Cities covered: Lille, Amiens, Dunkirk, Valenciennes
In the Hauts-de-France region, thermal challenges are linked to a cool and windy climate (zone H1a/H1b) with sustained energy needs during the winter months. Real estate projects primarily involve multi-family housing, commercial buildings, and urban regeneration. Our studies incorporate thermal bridge management, HVAC system performance, and acoustic constraints in dense environments.

Normandy
Cities covered: Rouen, Caen, Le Havre, Cherbourg
Normandy combines an oceanic climate with windy areas, requiring particular attention to airtightness and system durability. Residential and commercial projects incorporate moderate but continuous thermal constraints. Our RE2020 studies and dynamic simulations allow us to optimize energy systems in a humid and windy climate.

Pays de la Loire
Cities covered: Nantes, Angers, Le Mans, Saint-Nazaire
The Pays de la Loire region has a temperate oceanic climate (zone H2b), with increasing challenges related to summer comfort. Residential and commercial projects require precise optimization of HVAC systems and building compactness. Our interventions guide energy and acoustic choices during the design phase and ensure compliance with regulatory requirements.
