    A Data Center Simulation Framework Based on an Ontological Foundation
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Memari, Ammar; Vornberger, Jan; Marx Gómez, Jorge; Nebel, Wolfgang
    The IT-for-Green project aims at developing the next generation of Corporate Environmental Management Information Systems (CEMIS). Green IT being one important aspect of this, the ITfor- Green project seeks to support the analysis of a given data center situation and to support the simulation of alternative architectures to find ways to increase energy efficiency. To facilitate this, we develop a data center simulation framework, designed to be part of a larger CEMIS platform. This is achieved through a focus on flexibility, high interoperability and open standards. Flexibility is especially achieved by building the framework on top of an underlying data center ontology. This ontological approach allows us to derive many components of the framework from a single source, maintaining the ability to quickly adapt to future requirements.

    Environmental Footprinting in the IT-for-Green Project – A CEMIS Use Case
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Solsbach, Andreas; Rapp, Barbara; Teuteberg, Frank; Gräuler, Matthias; Stiel, Florian; Renatus, Fabian; Vornberger, Jan
    This paper presents functionality and design elements of a Corporate Environmental Management Information System (CEMIS) in the project IT-for-Green: Next Generation CEMIS for Environmental, Energy and Resource Management . The CEMIS under development in the IT-for-Green project uses a service-oriented architecture whose functionality will be demonstrated by means of a use case. Despite the theoretical development of CEMIS for as long as 20 years, CEMISs are not commonly used by companies. There is a substantial gap between the research and the use of CEMISs in companies, which the paper at hand aims to reduce by proposing a flexible and adoptable architecture to support companies in their current efforts. The developments in the case of company communication and the demands of stakeholders, especially in the field of corporate social responsibility (CSR) reporting, require handling. The development in the company communication and scientific community imply the extension of environmental to sustainability reporting which includes environmental, social and economic aspects. Current CEMIS are required to handle more and more business processes (as data source etc.) in the daily business of companies; the paper will indicate benefits of using an integrated CEMIS in the information technology (IT) landscape of a company. The paper will briefly introduce the IT-for-Green project and the software developed. The main focus is on a real world example the paper shows how our CEMIS can be used to assess the environmental impact of a product.

    Marker addresses: Adding identification information to Bitcoin transactions to leverage existing trust relationships
    (INFORMATIK 2012, 2012) Vornberger, Jan
    This paper proposes a technique for creating Bitcoin transactions enriched with special “marker addresses”1 to make it possible to easily identify the originating party and allow for special treatment by the recipient. In particular this technique can be used to implement secure zero-confirmation transactions between trusted parties without requiring an additional communication channel besides the Bitcoin network.
