A great recognition for our R&D work since 2015 on Acoustic Natural Ventilation Openings (ANVOs), as well as on the modelling and predictive methods used to design, size, and optimize these systems according to site conditions, façade exposure, and building use.

No longer having to choose between overheating and excessive noise !

We have developed modelling tools and methodologies to :

• predict future acoustic environments for different façades (transportation noise, neighbourhood activity, technical equipment, noise peaks, daytime and nighttime sound environments, etc.)
• assess the acoustic feasibility of natural ventilation through window opening for various façades and exposure scenarios, and determine, where necessary, the required sound attenuation performance for ANVOs
• design, size, and optimize the acoustic attenuation performance of ANVOs tailored to each project’s specific exposure conditions and occupancy requirements whenever needed.

 

If you are looking to deliver resilient buildings that prioritize natural ventilation in the context of climate change and rising temperatures, feel free to contact our teams to help address the acoustic challenges this may involve.

 

Many thanks to everyone who contributed to the construction of our ANVO prototypes, installed at the Gratte-Ciel Centre-Ville project house in Villeurbanne (France). This installation marked a key milestone in LASA’s long-term R&D programme, enabling the validation and further refinement of our sizing and optimization methodologies.

 

📍 Please feel free to contact us for an on-site demonstration of the prototypes.

 

Their development was made possible through the research work and funding associated with Charlotte Laffont’s PhD (supervised by Olivier Balaÿ – Architect DPLG, H.D.R AAU/UMR CNRS 1563/CRESSON, Professor at ENSAL, and Samuel Tochon-Danguy – Managing Director and Head of R&D at LASA), as well as through the partnership with Grands Ateliers Innovation Architecture via the “Habitat of the Future” teaching and research chair in architecture. We also thank all funding bodies (ANRT, UGA through the IdEx IRGA-2022 programme, SERL, LASA, and GAIA) and partners (TRIBU and Miralu).

 

Many thanks to the CidB, the CNB, and the jury for this award !

 

👏 Congratulations to the entire LASA team for this achievement — the R&D journey continues!
