We cannot build houses today as we did in the past and tolerate performance mistakes. The challenge for achieving European and national climate and energy targets is to ensure that low energy consumption is not only planned on paper but also actually built.

Since the beginning of 2021, the nearly zero-energy building standard has to be implemented for new buildings in EU countries. Moreover, is the low energy standard also obligatory for buildings undergoing a major renovation. The construction sector is thus facing the major task of executing these requirements.

Even small mistakes in the construction can lead to increased energy consumption and loss of indoor comfort. Therefore, the quality of construction work is crucial when building correspond to low energy standards. To ensure very low energy consumption, an airtight building envelope as well as professionally installed heating, ventilation and air-conditioning (HVAC) systems are required. Only by deploying optimally trained building professionals, a flawless implementation of nearly zero-energy buildings is possible.

The European project BUSLeague focuses on this issue by the upskilling of building professions and the increase of the demand of skilled labor by builders and companies. Within BUSLeague needed national competences in the building sector are identified and respective short trainings developed and implemented. Within the training implementation, a focus is set on the usage of innovative training methods and techniques that have already been successfully applied in national and European projects.
