Ambient Intelligent (AmI) applications are often meant to be used in complex and highly dynamic environments and are characterized by features such as context-awareness, personalisation, adaptivity and anticipation of user's desires. In this demo we focus on how the use of the high level of abstraction provided by multi agent-oriented technologies and related programming languages - and in particular of the ones rooted on a strong notion of agency - can ease the conceiving and realisation of AmI applications exhibiting such features. For doing this we present here an adaptive governance application, realised using the JaCaMo framework, for the dynamic management and allocation of rooms in the context of a smart co-working space.
