By developing a modern, easy to handle and everywhere accessible learning and teaching tool the project ConClip aims at updating skills of employees and learners in the construction business in order to be fit for the increasing demand of experts in the low energy and passive house construction sector. The development and application of multi-lingual video clips on most common construction defects to be downloaded on mobile phones but also on the ConClip website provide the opportunity of avoiding construction defects in low energy and passive houses and simultaneously equip migrant workers with a training tool in their mother tongue. Additionally ConClips will be implemented in training courses for persons working in the construction business and in institutions providing vocational training.
