According to National Oceanic and Atmospheric Administration, atmospheric CO2 has not been seen on the earth at this high level (400 ppm) for millions of years. The construction sector is responsible for 36% of all greenhouse gases in the planet. One of the ways to deal with this negative impact is to increase the use of sustainable and environmentally friendly materials in the construction sector. Timber sequesters carbon and can convert CO2 to O2, therefore it is seen as the best material to use. To direct the construction sector towards greater use of sustainable timber the Erasmus+ project HiTimber (Sustainable High-Rise Buildings Designed and Constructed in Timber) has been initiated in 2017. With the objective of developing a trans-disciplinary and international course in design, construction and management of sustainable high-rise timber buildings, the project aims at enhancing the quality and relevance of students’ knowledge and skills for the future labour market needs. In frames of the projects two workshops for bachelor degree students were delivered where the project-based learning approach (PBL) has been applied. This paper examines the effects of the PBL approach in transnational and interdisciplinary education in timber construction by examples and results from the HiTimber workshops. The presented results were derived from two surveys within the HiTimber project conducted in 2018 and 2019 where 29 lecturers and 45 students completed feedback questionnaires about PBL-based courses. In general all teachers and 85% of students were satisfied with the PBL approach. Further the results are based on two summer schools regarding wood organized by VIA University College, other summer schools and 14 workshops held around Europe with more than 400 students participating. The paper presents results concerning the teachers and students evaluation of planning, content and outcomes of the courses, discusses future perspectives and provides recommendations for the implementation of PBL in the different courses with similar structure and objectives.
