Alfa-college’s Challenge is called ‘Circular Experience Concept’ and involves developing a conceptual interpretation of the EnergyHub050 building. What will an interactive showcase of state-of-the-art techniques in the field of energy & material use look like? SMEs and startups from the region are challenged to apply their new innovations in the temporary building, so that it also becomes a stage for these companies. Their solution, the background, material choices, the impact it achieves; it should all be made known in a good way. See, feel, hear, experience, the senses must be stimulated.
