logo bertimThree new partners joined the BERTIM project in August 2016, after the voluntary withdrawal of the previous three partners in order to tackle their responsibilities.

The outgoing partners, Martinsons Byggsystem KB, Brabrand Boligforening (BBBO) and Collage Arkitekter AB, decided to leave the BERTIM consortium due to different reasons. The first one, Martinsons, a Norwegian wood manufacturer, decided to leave because they had not enough human resources to deal with such a great project. The second one, BBBO, a Danish social housing association which managed a big amount of residences in Denmark, requested to leave since its buildings’ typology did not match the required ones in BERTIM. Finally, Collage, a Swedish architectural firm, opted for quitting after being taken over and some structural changes were carried out.

With this background, the structure of the consortium focused in geo-cluster remained harmed, mainly regarding the North of Europe area, where the climate conditions are exceptional and hence interesting from the point of view of energy efficiency.  Therefore, the searching had to be focused in Northern partners in order to get the necessary replicability in this project.  In this context, three new partners coming from North of Europe decided to join in the project so as to represent the Nordic climate conditions, strengthen the wood manufacturing distinctive from the North of Europe and participate actively in the expected outcomes. They are: Omsorgsbygg Oslo KF (OBY) or Oslo Kommune (Norway), Lulea Tekniska Universitet or LTU (Sweden) and SETRA Trävaror AB  (Sweden).

Omsorgsbygg Oslo KF (OBY), owned by the City of Oslo, is a public enterprise established in 2004. They own, manage and develop municipal facilities, consisting of an approximate floorage of 900.000m2. Omsorgsbygg owns and manages the cities kindergartens, nursing homes, fire stations, youth clubs, municipal senior residents and libraries. In BERTIM project they will provide a demonstration building to be refurbished with BERTIM modules, and also they will share their experience from a public building owner´s perspective.


SETRA is one of the Sweden´s largest wood products companies. Recently they have undergone a big restructuring, taking advantage of its great experience and knowledge regarding  the wood industry, to focus on developing wood components for construction field. SETRA is involved in several R&D programs with  Luleå University of Technology related to the wood working processes. Their experience will be key in BERTIM project, enabling the design, manufacturing and installing the BERTIM modules based on CLT systems, adapted to the climatic zone of North Europe. They will also study the possible implementation of automation systems for the mass manufacturing of prefabricated modules in their industrial settings.


The research group of wood Science and Engineering at Luleå University of Technology (LTU) is focused on processes which enables better and cheaper building and housing with wood.  Its equipment and technology (X-ray computer tomography scanner among others) allows specific wood studies such as swelling and shrinking behaviour, delaminating phenomena, crack development etc… in controlled environments concerning temperature and humidity controlled environments. Furthermore, detailed log models allow advanced studies on maerial efficiency in wood manufacturing processes. The role of LTU in BERTIM is to study technology in order to improve the performance of wood elements devoted to building energy retrofitting. In addition, they will support the manufacturer SETRA in the design and manufacturing of BERTIM panels, working together in the optimization of the whole process.


They have officially became partners of the consortium since August, although they were invited to the Second General Assembly held in Charité sur Loire in June 2016 in order to know longer about the project. Since that moment, they have been participating actively in different tasks.

We would like to extend them a warm welcome to consortium and we hope that their entry will contribute to the success of the BERTIM project, achieving great outcomes together.
