    Concept and Implementation of a Service API for the Remote Access to Life Cycle Assessment Databases
    (Innovations in Sharing Environmental Observations and Information, 2011) Düpmeier, Clemens; Kusche, Oliver
    For implementation of political concepts like the Integrated Product Policy (IPP) of the European Union, which aims at a “sustainable society”, it is inevitable to widely apply in industry methods of Life Cycle Assessment (LCA), which analyze the whole life cycle of products with respect to sustainability topics like resource usage 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 background data. But LCA modellers often face the problem of needing datasets from different LCA databases or data sources for a study. And these datasets typically have different formats and cannot be easily used together because their nomenclature and references to common elements are not harmonized. This results in tedious manual work which has to be performed by the modellers to merge such datasets into an already existing internal database within their LCA tool. The open source project SODA4LCA led by the Institute of Applied Computer Science at the Karlsruhe Institute of Technology in cooperation with other partners tries to solve such problems of dataset providers and modellers through concepts and corresponding implementations for building up service-oriented infrastructures for LCA on the Internet. The SODA4LCA LCA database application as one of the main outcomes of the project implements a service-oriented API which allows it to build up networks of LCA database nodes maintained by different data providers. Tools used by modellers can connect to these data networks and query, retrieve and even upload data in an easy and consistent way. The SODA4LCA service API and its applicability will be described in more detail in this paper.

    Creating LCA Data Exchange Networks
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Kusche, Oliver; Düpmeier, Clemens; Recchioni, Marco; Mathieux, Fabrice
    In the Integrated Product Policy Communication of 2003, the European Commission recognised Life Cycle Assessment (LCA) as “the best framework for assessing the potential environmental impacts of products”. It also identified “the need to improve data availability and quality worldwide by internationally cooperating on LCA data and methods”. To address this situation and to foster standardization, the ILCD (International Life Cycle Data) format was developed by the European Commission’s Joint Research Centre (DG JRC) and implemented by the Institute of Applied Computer Science (IAI) of the Karlsruhe Institute of Technology (KIT). IAI also implemented an LCA database application for storing ILCD datasets by the name of soda4LCA (service oriented database application for LCA), which was published under an Open Source license. Subsequently, the idea of establishing a global, decentralized data network for high quality LCA datasets based on the ILCD format called the ILCD Data Network has been proposed and first data network features were implemented in soda4LCA. This paper summarizes requirements for implementing LCA data networks and presents the already implemented network features as well as an outlook to future enhancements of soda4LCA. It also presentshow these features are instrumented by the ILCD Data Network.

    Extending the ILCD Format to Support Environmental Product Declarations of Construction Products
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Kusche, Oliver; Düpmeier, Clemens; Braune, Anna; Brockmann, Tanja; Rössig, Stephan
    The German Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) is publishing a database of Environmental Product Declarations (EPDs) for construction materials and components, the KOBAU.DAT. The data format is based on the European Commission s International Reference Life Cycle Data System (ILCD) data format, which has been extended to fit the specific needs of this application. With the new EN 15804 standard for Environmental Product Declarations for construction products, the KOBAU.DAT as well as the underlying data format needed to be revised to comply with the new standard. In order to make it easier for software tool developers to adapt tools to the EPD data format, it is desired to make the EPD format as much as possible compatible with the ILCD format. In this paper, it is bescribed how the ILCD data format can be used with only a few minor additions to describe Environmental Product Declarations for construction products according to EN 15804.

    Key IT-results of the BioEnergieDat Project
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Düpmeier, Clemens; Schebek, Liselotte; Ciroth, Andreas; Kusche, Oliver
    The BioEnergieDat project had been carried out by a consortium of German research organizations for the German Ministry of Environment as one important part of the German Sustainable Biomass Strategy. The main goals of the project were the development of a comprehensive database of LCI data sets describing important Bioenergy process chains in a flexible and customizable way and the development of an associated open source software infrastructure for LCA modelling of Bioenergy technologies for German framework conditions. One of the main requirements of the project was that the provided data sets can be used in different LCA modelling situations and shouldn t restrict users to only one usage context, i.e. performing only a certain type of LCA study. Therefore, new methodological approaches and enhancements to the underlying data set model / format had also to be developed and implemented to fulfil these requirements. Both, the tool environment developed in BioEnergieDat for LCA modelling of bioenergy technologies and key IT-aspects to support the new modelling approaches are described in further detail.

    Managing LCI Data from Different Workgroups within the same Instance of an LCA Database
    (EnviroInfo Dessau 2012, Part 2: Open Data and Industrial Ecological Management, 2012) Düpmeier, Clemens; Greceanu, Claudia; Kusche, Oliver; Schmitt, Christian
    Life Cycle Thinking (LCT) and Life Cycle Assessment (LCA) are the scientific approaches behind modern environmental policies and business decision support related to Sustainable Consumption and Production. For the efficient and reliable application of LCA, it is necessary that LCA studies are based on consistent, transparent, and qualityassured Life Cycle Inventory (LCI) data. To manage and provide such consistent and quality assured Life Cycle data to users the Institute of Applied Computer Science of the Karlsruhe Institute of Technology developed an open source service oriented LCA database software (soda4LCA) that can be accessed directly from within LCA tools to store, manage and extract LCA datasets via the Internet. Different soda4LCA instances can even be connected together via the Internet to form a LCA data network which can then be used by users via one of the network nodes. Because of user requirements, the storage model of soda4LCA is enhanced in the current development version to support the management of largely separated collections of datasets (called data stocks) by different working groups. This can be seen as a first step to support multitenancy in soda4LCA. It’s also possible in the current development version to build other logical collections of datasets for such use cases as compiling collections of datasets for review or release management. Data stocks are also the key element of soda4LCA to provide dataset replication via nodes of a soda4LCA data network. Further details of the data stock concept and its usages will be described in the following chapters.

    The International Reference Life Cycle Data System (ILCD) Format – Basic Concepts and Implementation of Life Cycle Impact Assessment (LCIA) Method Data Sets
    (Innovations in Sharing Environmental Observations and Information, 2011) Wolf, Marc-Andree; Kusche, Oliver; Düpmeier, Clemens
    In the context of its efforts to facilitate environmental sustainability, the European Commission is promoting and supporting the use of life cycle data and tools through its European Platform on LCA. Objectives of this project are to develop the International Reference Life Cycle Data System (ILCD) Handbook as authoritative guidance on LCA, to contribute key European scope quality data sets via the European Reference Life Cycle Database (ELCD) as well as to implement the ILCD Data Network as infrastructure for LCA data, open to all data developers. Both the ELCD database and the ILCD Data Network rely on the ILCD data format as reference format and for data exchange. In the initial release of the ILCD data format, only a draft specification for LCIA method data sets had been included, which has been enhanced and finalized in the meantime, addressing feedback from an earlier public stakeholder consultation process and reflecting insights when documenting the ILCD-recommended LCIA methods. The finalized ILCD method dataset specification is now implemented in software and will enable tools to easily import and apply new LCIA methods documented in the ILCD data format. In this paper, the new LCIA method dataset specification and its corresponding software implementation are presented. The history and idea behind the data format is briefly addressed as well as how the adoption among tools and databases is progressing. The basic structure of the ILCD data format is presented, with the different data set types and their relationships to each other. Then, the structure of the LCIA method data set and its modeling capabilities are explained. Furthermore, technical considerations for tool integration are discussed. Briefly, an exemplary LCIA method instance data set of a draft recommended LCIA method for Europe, foreseen for release by the European Commission’s DG JRC, is presented to illustrate the use of the finalized dataset type implementation. Finally, an outlook on future developments is given.

    Towards a Complete Tool Chain for Eco-Balancing Governmental Buildings
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Düpmeier, Clemens; Kusche, Oliver; Brockmann, Tanja; Rössig, Stephan; Ciroth, Andreas; Lode, Tobias
    With the Assessment System for Sustainable Buildings for Federal Buildings (BNB), Germany is pioneering the implementation of certification systems for Sustainable Buildings in Europe. Using BNB methodology and tools, building products are not assessed as individual products, but looked at within the context of the entire building and its parts. The most important impacts of the building on the global environment (i.e. environmental burdens like ozone depletion or consumption of resources like energy and water) are assessed by means of Life Cycle Assessment (LCA) methodology and are calculated according to the Type III Environmental Product Declarations (EPD) standard for building products described in ISO 14025 and EN 15804. This paper will describe the tool chain needed to first calculate EPD data sets in LCA tools, store them in a central repository, the ÖKOBAU.DAT, and how the EPD data sets can then be used in other tools for calculating the environmental footprint of an entire building.
