Pervasive environments support users' daily routines in an invisible and unobtrusive way. To do so, they include a technical pervasive infrastructure, which is aware of and adaptive to both the operational context and the users at hand. Non-Functional Requirements (NFRs) have been effectively used to inform decision-making in software engineering: functional alternatives are compared in terms of their contribution to NFRs satisfaction. In this paper, the authors consider user preferences over NFRs as a key driver for the adaptation of a pervasive infrastructure.
