New competences for the construction sector to achieve NZEBs

One important barrier that hampers the development of Nearly Zero-Energy Buildings (NZEBs) and effective renovations (up to NZEB levels) is the lack of adequate construction competences (knowledge, skills, autonomy and responsibility). Improving the competences of middle- and senior-level building professionals, as well as the various trade professionals (construction workers) in sustainable energy efficient construction is therefore of key importance. Practical experience demonstrates that many construction mistakes happen, particularly when details and joints are considered, which can greatly affect the energy performance of the building and the appearance of construction damage. Several relevant examples of buildings in Croatia will be presented, with the conclusion that in the field of energy efficiency increased control and quality assurance is needed to improve the quality of works. Besides the fact that the lack of quality is often caused by the lack of competences, building professions also need to be aware of new and upcoming challenges relating to NZEBs. These include new materials and products, the integration of renewable energy sources, new systems or processes, and the use of Building Information Modelling (BIM) tools. All of this leads to the conclusion that upskilling towards energy efficiency and NZEBs should be done throughout the entire value chain of the buildings sector (including designers, architects, engineers, building managers, technicians, installers and workers including apprentices). There are several initiatives to upgrade professional competences in NZEB design and construction, thus increasing the experts’ capacity to tackle NZEB implementation in actual building stock throughout Central European Initiative Member States. Accordingly, the efforts made in Croatia through the Croskills project (BUILD UP Skills initiative) on training of construction workers will be shown as well as the Ordinance on the system of training and certification of construction workers which install building elements that affect building’s energy efficiency (OG 67/2017). The efforts on developing new competences are continued through the Horizon 2020 projects developing multi-country qualification and training schemes such as Fit-to-nZEB (Innovative training schemes for retrofitting to nZEB-levels) and Net-UBIEP (Network for Using BIM to Increase the Energy Performance) which will also be presented.
