The overall aim of BUSLeague is to address and overcome the challenges of the stimulation of demand for energy skilled workforce (demand side), along with hands-on capacity building to increase the number of skilled workforce across the building design, operation and maintenance value chain (supply side). BUSLeague will achieve this objective by developing and implementing a cross European recognition of energy skills, together with upscaling successful training methods and techniques which have already been developed in previous EU and National initiatives such as BUILD UP Skills, Construction Skills. BUSLeague focusses on a blend of four elements: mutual recognition of energy skills, awareness raising, capacity building and legislative changes. Implementation will be done at country specific and regional levels; based on a blend of measures to stimulate demand complimented with hands-on and practical upskilling of involved local and regional workforce. In this way engagement of SMEs will be ensured. BUSLeague is formed by a coalition of former BUILD UP Skills and Construction Skills projects. The partners believe that by working together the national implementation plans and developed means will improve and become more attractive and effective. BUSLeague is strengthened by experienced anthropology researchers and educational technology researchers in order to prove impact and to optimize the blends for stimulating demand and optimizing learning transfer of applied learning means and materials.
