EN Acoustic Design
The laboratory develops knowledge and techniques for the acoustic design of the environment, in collaboration with energy design and computer-aided design and manufacturing (CAM + CAD). This integrated approach allows the optimization of acoustic performance, taking into account energy and environmental requirements. Through the use of modeling and simulation software, the laboratory offers innovative solutions for sustainable and efficient projects.
The Laboratory of Sustainable Design of the Built Environment plays a decisive role in promoting the acoustic quality of the environment. It actively participates in the design of spaces that harmoniously integrate the principles of sustainability and sound comfort. Its work covers three main areas: environmental acoustics, room and building acoustics, and sound atmospheres and soundscape. Through research and educational programs, it contributes to raising awareness about the importance of good acoustic design for user well-being.
Environmental Acoustics
In the field of environmental acoustics, the laboratory actively contributes to the implementation of Directive 2002/49/EC relating to the assessment and management of environmental noise. It participates in research and studies aimed at the preparation of Strategic Noise Maps (SNM) and the development of Noise Action Plans (NAP). It aims to analyze and mitigate the impacts of noise in urban and natural environments, promoting the adoption of sustainable solutions and the improvement of quality of life.
Acoustics & Building Applications
In the field of room and building acoustics, it plays a crucial role in architectural studies for the design and construction of meeting rooms, theaters, and residences. The importance of proper acoustic design is essential to avoid acoustic defects and limit extra post-construction costs. By integrating acoustic solutions from the beginning of the design, we ensure sustainable spaces where user well-being is at the center.

Ambiances and Soundscape
In collaboration with the CRESSON team of CNRS Ambiances Architectures Urbanités, it develops original and innovative methodologies for analyzing the physical dimensions of sound atmospheres in architecture, integrating these data into the overall design process.
The goal is to develop tools and methods for integrating physical and aesthetic dimensions into architectural and urban design. This involves the development of sound atmosphere sketching tools, which allow designers to predict the acoustic qualities of their project.
Biosourced Materials
An emerging direction is the use of bio-sourced materials, including those derived from regional agricultural residues. These materials reduce the carbon footprint of the building sector while valorizing agricultural by-products. Their acoustic properties, combined with their low environmental impact, make them ideal choices for sustainable constructions. The laboratory actively explores these approaches for a more responsible architecture.
Acoustic Measurements and Simulations
The laboratory has a wide range of specialized software and high-precision measuring instruments. These tools allow the performance of advanced acoustic simulations to evaluate and predict the acoustic characteristics of spaces under design. In addition, they are used for detailed measurements of existing environments, providing critical data. It also plays an important role in understanding soundscapes and provides advice to creators and architects.
The laboratory's work is also directed towards the development of measurement protocols adapted to non-standard architecture. The goal is to formulate a framework for defining non-standard acoustic measurements.
