Abstract. Ambient intelligent systems are defined as being able to per- 
ceive their environment, being aware of the presence of people and other 
agents, and respond intelligently to these agents' needs. Today the hard- 
ware requirements for achieving these capabilities are met. Earlier work 
have argued that knowledge intensive case-based reasoning is a feasible 
method for ambient intelligence. In this paper that argument is sup- 
ported by testing of an implementation in a hospital ward domain, which 
shows that despite some issues related to the current implementation the 
case-based reasoner performs at an acceptable level.
