    Ambient Assisted Energy Management
    (Environmental Informatics and Industrial Ecology, 2008) Welge, Ralph; Bollow, Eckhard; Faasch, Helmut; Moeller, Andreas
    While discussing mainly new Web 2.0 developments, another wave of information technology comes up to industrialized societies: Ambient computing, wearable computers, and the Internet of Things. This new wave of computing does not only change the relationship between humans and computers; it is as well a question of (non-) sustainable development: increasing consumption of resources and energy in the production phase, reduced periods of use phases (for example: the life-cycle of mobile phones is significantly reduced), and increasing problems in recycling and waste disposal. But ambient computing has also a high potential to modify the society’s treatment of resources and energy. The interaction with “intelligent” things can change our conception of production and consumption: instead of input and output rather “from cradle to cradle” (Braungart) or “socio-technical metabolism” (the underlying image of industrial ecology). In this paper we present an ambient computing approach to decentralized energy management. From our point of view, this is only the first step to realize IT-based industrial metabolism in industrialized as well as developing countries. Nevertheless, first experiences demonstrate that the cooperation of different sustainability sciences is required. An important role plays computer science (environmental informatics). This contribution is written mainly in the computer science perspective.

    Building Assistance Systems using Distributed Knowledge Representation
    (Environmental Informatics and Industrial Environmental Protection: Concepts, Methods and Tools, 2009) Welge, Rlaph; Bauch, Dennis; Bollow, Eckhard; Faasch, Helmut; Möller, Andreas
    The design of adaptive buildings requests assistance systems, which grant the intuitive integration of users and visitors into smart buildings arrangements. Such assistance systems can redound to offer user-specific monitoring information of the building services management system with selective apperceptions – auditory and visual – of complex environment situations. These systems can improve the interaction of the individual users with the technical environment by offering access to cooperative components that act and react customized to their specific preferences. Assistance systems however can boot the collateral user interaction in the sense of „Community Building“ for the common definition of goals – for example the adaption of decentralized energy consumption to the general supply situation. The assistance systems can provide decision bases or semi-autonomous behavior for decentralized – potentially just indirectly communicating users. The huge number of interaction possibilities should not lead to further interfaces with explicit handlings. Instead of that this paper proposes a modern form of implicit man-environmentcommunication. It is shown that the embedding of knowledge management methods into distributed systems enables the cooperation of device meta services. Technical devices, house establishments and internet services provide these meta services using the semantic knowledge description language OWL. The meta services communicate and synchronize with a mobile single-chip-computer with the description of the user’s own preferences. With the example of a straightforward ontology it is shown how a presence control switch is semantically modelled in description logic, how it is published and distributed within the system, aggregated at runtime and how it is used to control the actors by interfering.
