    Das Zuhause smart machen – Erfahrungen aus Nutzersicht
    (Mensch und Computer 2016 - Tagungsband, 2016) Jakobi, Timo; Ogonowski, Corinna; Castelli, Nico; Stevens, Gunnar; Wulf, Volker
    Kleinere, günstigere und effizientere Sensoren und Aktoren sowie Funkprotokolle haben dazu geführt, dass Smart Home Produkte in zunehmend auch für den privaten Massenmarkt erschwinglich werden. Damit stehen Hersteller und Anbieter vor der Herausforderung, komplexe cyber-physische Systeme für Jedermann handhabbar zu gestalten. Es fehlen allerdings empirische Erkenntnisse über die Rolle von Smart Home im Alltag. Wir präsentieren Ergebnisse aus einer Living Lab Studie, in der 14 Haushalte mit einer am Markt erhältlichen Smart Home Nachrüstlösung ausgestattet und über neun Monate empirisch begleitet wurden. Anhand der Analyse von Interviews, Beobachtungen und Co-Design Workshops in den Phasen der Produktauswahl, Installation, Konfiguration und längerfristigen Nutzung zeigen wir Herausforderungen und Potentiale von Smart Home Systemen auf. Unsere Erkenntnisse deuten darauf hin, dass das Smart Home immer noch von technischen Details dominiert wird. Zugleich fehlen Nutzern angemessene Steuerungs- und Kontrollmöglichkeiten, um weiterhin die Entscheidungshoheit im eigenen Zuhause zu behalten.

    Findings of an Action Research on implementing an Integrated Energy Management in a German SME
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Schönau, Niko; Schwartz, Tobias; Jakobi, Timo; Castelli, Nico; Stevens, Gunnar
    The responsible and sustainable use of energy in private, public and business environments is one of the major societal challenges of our time. An essential part of this challenge is to increase the energy efficiency of (high energy) companies and implementing a sustainable energy management. In this paper we demonstrate that this is a complex socio-technical problem that asks for a holistic view and the need of integrated energy management systems without neglecting the difference between the needs and roles of the various stakeholders in a company. These findings are based on an ongoing action research where we conduct interviews with 15 groups of interest in the company that is operational in the area of fastening technology and has more than 2300 employees in 30 subsidiaries.

    Switch off the light in the living room, please! –Making eco-feedback meaningful through room context information
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Castelli, Nico; Stevens, Gunnar; Jakobi, Timo; Schönau, Niko
    Residential and commercial buildings are responsible for about 40% of the EU’s total energy consumption. However, conscious, sustainable use of this limited resource is hampered by a lack of visibility and materiality of consumption. One of the major challenges is enabling consumers to make informed decisions about energy consumption, thereby supporting the shift to sustainable actions. With the use of Energy-Management-Systems it is possible to save up to 15%. In recent years, design approaches have greatly diversified, but with the emergence of ubiquitous- and context- aware computing, energy feedback solutions can be enriched with additional context information. In this study, we present the concept “room as a context” for eco-feedback systems. We investigate opportunities of making current state-of-the-art energy visualizations more meaningful and demonstrate which new forms of visualizations can be created with this additional information. Furthermore, we developed a prototype for android-based tablets, which includes some of the presented features to study our design concepts in the wild.

    Towards Collaborative Green Business Process Management
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Jakobi, Timo; Castelli, Nico; Nolte, Alexander; Stevens, Gunnar; Schönau, Niko
    Sustainable and efficient energy management poses a major challenge for organizations, as well as the whole society. Organizational strategies for saving energy are currently largely coined by two main courses of action: Green process optimization and investing into more energy efficient infrastructure, or energy campaigns or feedback mechanisms. We show how both approaches face limitations concerning the scope of intervention and carve out the necessity for an integrated approach on fostering sustainability in organizations and envision a Collaborative Green Business Process Management. Such modell should integrate all stakeholders, thus bridging the gap between strategic planning and everyday work in order to manage sustainability strategies more effectively and efficient. We conclude in laying out a research agenda, which we seek to address in course of an ongoing research project within a long term cooperation with several different organizations.

    Towards Data Spaces for circular economy and green business value networks
    (EnviroInfo 2023, 2023) Rilling, Lukas; Schneider, Alexander; Castelli, Nico
    Circular economy (CE) has been identified by several studies as the necessary reformation of the industry to decrease the environmental impact of production in the fight against climate change. Some studies have identified the lack of technological solutions to support the move towards a circular economy where among others the digital networking and data exchange is one of the most pressing and general problems which must be solved cross-industry and cross-country. This paper therefore identifies the most important requirements for a digital infrastructure to support CE and proposes a solution that combines all these factors by using Data Space concepts and technologies as the backbone for collaboratively collecting data in form of Digital Product Passports (DPP).
