Building at height is an interesting way of reducing the degradation of land and thus reducing the pressure on biodiversity, among other things. Companies in the Norwegian Wood Cluster have identified acoustics as an important area for strengthening the competitiveness of wooden buildings, including in the 4-6 storey segment. The cluster has now set up a project that will collect and make available sound measurements for floor partitions in wooden buildings with a view to producing several preaccepted solutions and providing the basis for a guide.
Well anchored
– “The idea for the ‘3LYD’ project came up in a working meeting with key people from our members NTNU, Norconsult and Sweco,” says cluster leader Berit Sanness. She says that the project idea then received full support from the cluster’s specialist group “Future building solutions”.
– That’s why we went ahead and planned the project. A number of member companies, NTNU and SINTEF actively contributed to finalizing the project plan. With support from Innovation, the three-year project is underway, and we have had the first meeting of the project group,” says Sanness. She is now handing over responsibility for the project to the cluster’s new project manager Julie Gedde-Dahl.
Great commitment
– The 3LYD project group held its first meeting on February 19. It was attended by resource persons with strong technical expertise from SINTEF, NTNU and a number of companies, and the level of commitment was high. It was very motivating,” says Gedde-Dahl. She says that the acoustics theme has also captivated the students. A total of 12 bachelor’s students have chosen assignments related to the project, nine students at Gjøvik and three in Trondheim.
– “We’re very pleased that NTNU has been heavily involved in the project and that so many students have chosen acoustics in wooden buildings for their assignments. The students will have co-supervisors from the companies, so we think they will find the work on the assignments interesting. And we look forward to getting to know the results of the students’ work,” says Julie Gedde-Dahl.
She expects problems to emerge that may tempt new cohorts of bachelor’s and master’s students at NTNU in Gjøvik and Trondheim to choose assignments in acoustics in wooden buildings in the coming years.
– “The company’s involvement in the ‘3LYD’ project is already considerable. This underlines the industry’s interest in the field,” says Gedde-Dahl.
Project “3LYD”
These are actively participating in the “3LYD” project, which is owned by the Norwegian Wood Cluster: SINTEF and NTNU, ARE Treindustrier AS, Hersleth Entreprenør AS, Hunton Fiber AS, Kontur Arkitekter AS, Norsk Massivtre AS, Ny Struktur AS, Norconsult Norge AS, Sweco Norge AS and Brekke & Strand Akustikk. Faggruppe Fremtidige byggeløsninger is the reference group for the project.
The project is supported by Innovation Norway and runs from 2024-2027.
