    A Plugin-Based Framework for Domain Models and Persistence in Environmental Management Information Systems
    (Environmental Informatics and Industrial Ecology, 2008) Busse, Thorsten; Denz, Nicolas; Page, Bernd
    In this paper, we present an open source framework that supports the implementation of persistable domain models in dynamic plugin-based architectures on Microsoft .NET. The framework includes a domain model service that allows plugins to provide new domain types to other plugins as well as to use, extend, and observe domain objects contributed by other plugins. Furthermore, a persistence service is provided as an abstraction from concrete repository implementations. The paper discusses our solutions to the challenges of persistence in dynamic architectures, presents an exemplary domain-specific language for material flow analysis, and compares our work to related approaches from the common software platforms .NET and Eclipse. Though the framework is in principle application- independent, we apply it primarily in the context of environmental management information systems.

    A Tool for Modeling and Optimization of Residential Electricity Consumption
    (Environmental Informatics and Industrial Ecology, 2008) Eysholdt, Moritz; Denecke, Ulrich; Belasus, Michael; Bley, Christian; Eilers, Mark; Erlmann, Michael; Hinrichs, Christian; Hurrelmann, Malte; Bremer, Jörg; Rapp, Barbara; Sonnenschein, Michael; Vogel, Ute
    Today's households face a huge variety of electricity consuming devices on the one hand, and increasing electricity prices and increased awareness for environmental sustainability on the other hand. Fluctuating electricity tariffs currently evaluated by electricity suppliers have the potential to make it even more complex for the electricity consumer to keep costs low. We want to help the consumer to manage this complexity and increase her or his awareness for the electricity consumption of the household's devices. Therefore, we have developed a tool which allows modelling and simulating the set of electricity consuming devices, their loads, and electricity tariffs. It is possible to create schedules for the usage of devices, calculate the resulting load curve and automatically optimize the schedule based on fluctuating power tariffs while paying attention to customer definable constraints. Furthermore, the tool allows comparing modeled and metered load curves, which is especially useful to evaluate correctness and completeness of the household's model. To decrease the modeling effort, the tool can access libraries of predefined devices and tariffs via the Internet.

    Adaptation Planning Framework to Climate Change for the Urban Environment in Ho Chi Minh City
    (Environmental Informatics and Industrial Ecology, 2008) Storch, Harry; Schmidt, Michael
    The overall objective is to develop and incorporate adaptation into urban decision-making and planning processes with designation criteria and zones that will lead to an increase of resilience to climate-related physical and social vulnerabilities of the urban system of HCMC. Climate Change will likely change current climate conditions and lead to an ongoing sea-level rise and increase in extreme weather events such as heavy rainfall and heat waves etc. These climate related events cause a multitude of potential impacts and risks not only to natural areas but specifically to populations of densely built up metropolitan areas. In foreseeable future they may also cause indirect negative effects such as severe urban floods or disturbances of the energy supply or public transport systems in urban areas. The main task of assessing climate change related impacts in urban areas is to estimate the possible damages that might arise for human-influenced systems by climate change, including extreme weather events. In general there are two elements that define the potential risk: first, the probability of the occurrence of the events and second the “elements” at risk. Events to be included are heat waves, heavy rain, floods etc. "Elements” at risk are not only assets like houses, urban infrastructure services or economic losses, but also human health and livelihood.

    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.

    Automated Reporting of Corporate Sustainability Data – an Analog of Automated Internet-based Sustainability Reporting Using XML
    (Environmental Informatics and Industrial Ecology, 2008) Morhardt, J. Emil
    Extracting information from corporate sustainability reports for analysis is a labor-intensive process fraught with risks of misclassifying or missing relevant material. The use of a GRI index helps to some extent, but the main problem is a lack of standardization of language that would make automated searching feasible. The need for such standardization would be entirely obviated if every piece of data in the report were tagged in some machine-readable way, such as XML. This paper discusses a parallel process in which all data generated by the Roberts Environmental Center reside in specific database fields and are extracted automatically on demand to meet the needs of web pages and reports. The data for the web pages are retrieved in XML-tagged format for the purposes of driving web page graphics. These data are embedded in the web pages and could be processed by end users, if they wished, to create tables or other output in addition to the graphs. Exactly the same database-querying techniques could return all the data about a specific report in our database in a single XML document. Such an approach might be useful for companies wishing to tag their sustainability reports with XML. If all of the data for the report, including text blocks, were contained in a database (as is the case for all Roberts Center reports), the XML extraction routine would need to be written only once, and new data would automatically be available to web pages parsing the XML. Analyzing the content of such reports would be greatly simplified.

    Business Models for Open Source Projects in Environmental Informatics
    (Environmental Informatics and Industrial Ecology, 2008) Ciroth, Andreas
    Generating a healthy business model is one of the main challenges when setting up an open source project. In this presentation, I will explore how sound, healthy business models for open source projects can look like, with a focus on environmental informatics. I will do so by first analysing which elements of open source projects exist that can, potentially, generate turnover, and will then estimate the relevance of these different elements, for different types of projects, taking into account costs and other efforts. This will be illustrated by several cases, including the openLCA project where I am involved in myself. Result of this is an overview of types of business models of successful open source projects, that each deploy means that fit best to their specific situation. Result is further that these business models frequently do not follow a common pattern; finding these requires often a wider view of analysis, and more creativity, and under certain circumstances, business models are likely to fail. These critical circumstances will be highlighted, as to be carefully avoided when tailoring a new project. I will conclude with a tentative outlook on further development of the identified project types.

    Challenges of Providing an Internet-based Data Management Infrastructure for a National Supply of Life Cycle Inventory Data
    (Environmental Informatics and Industrial Ecology, 2008) Stadtherr, A.; Düpmeier, C.; Kusche, O.
    To implement political concepts for sustainable development, for example, the Integrated Product Policy (IPP) of the European Union, it is inevitable to facilitate wide application of Life Cycle Assessment (LCA) and related methods in many decision contexts within industry and politics. LCA analyses the whole life cycle of products with respect to sustainability topics like resource usage, emissions, and other environmental impacts. For the efficient and reliable application of LCA, it is necessary that LCA studies are based on consistent, transparent, and quality-assured data. Hence, activities in Europe and worldwide are increasing, which are aimed at establishing national and international databases and supplies for basic Life Cycle Inventory (LCI) data. Apart from being an information and collaboration platform of the scientific community in the field of LCA in Germany, the most important goal of the German Network on Life Cycle Inventory Data (NetLCD, http://www.lci-network.de) is to establish a supply of harmonised, regularly updated, and quality-assured basic data for LCA in Germany (LC Data). The implementation of such an Internet-based IT infrastructure for data and quality management of basic LCI data sets is associated with many technical challenges. In this paper, some of these challenges and the main concepts of the current implementation of the supply of LCI Data will be described by the authors, who are developing the IT infrastructure for NetLCD. Central ideas to face some of the challenges are the usage of XML as a native storage format of LCI data sets within an Oracle database and the integration of the data supply in an Internet portal. The first idea is to overcome limitations of otherwise too hard coded data semantics of data sets. The second idea is to enable the implementation of a workflow-oriented collaborative quality control mechanism on top of the database using a tight integration of quality and review information in the portal, data set representation in the database, and a reviewer as a person.

    Challenges of SEIS and SISE: Integrating Environmental Knowledge in Europe
    (Environmental Informatics and Industrial Ecology, 2008) Hrebicek, Jiri; Legat, Rufdolf; Nagy, Michael; Pillmann, Werner
    There is shortly introduced the eEnvironment (Electronic access to Environmental information) as a part of eDemocracy (the use of electronic communications technologies such as the Internet in enhancing democratic processes within a democratic state or representative democracy) and tools for its implementation: the Shared Environmental Information System (SEIS) and a Single Information Space in Europe for the Environment (SISE). The eEnvironment fully supports the principles of eDemocracy and its new trends are discussed in the paper together with topics of prepared conference “Towards eEnvironment (Challenges of SEIS and SISEE: Integrating Environmental Knowledge in Europe)”, which will be held on March 25.-27.3.2009 in Prague during the Czech Presidency of the Council of the EU and will be focused for finding of answers on above challenges from scientific, organisation and political point of view.
