In the area of the Wastewater Association Traisen, heavy stormwater events in the past years repeatedly caused flooding in the settlement area. The predicted increase in heavy rainfall caused by climate change is more likely to cause flooding if no countermeasures are taken in the catchment area. The subject of the project is the investigation of the current situation in the Wastewater Association Traisen from the point of view of integrated urban water management and spatial planning. The aim of the research project is the development of a method for urban water analysis of the adaptation and decoupling potential of spatial structures. This builds on data collected by engineering offices of the drainage effective areas, and extends them to spatial data on building types, land use, land availability and ownership structure. Based on this, the adaptability of structural types to different rainwater management measures and the impact assessment of these measures will be analyzed. The project will develop a methodological approach that can be applied across the whole association. It will be applied and tested in selected sub-basins depending on the available database. The goal is to identify priority action areas to improve the flood problem. In a sub-catchment area of the association area, an integrative spatial strategy of urban drainage and different development scenarios will be developed in workshops with political decision-makers, stakeholders and project participants Finally, the methodology will be discussed with all members of the Wastewater Association in order to ensure the transferability of the results. Project work is carried out in cooperation with local engineering offices and municipalities, which provide the necessary data.

The Styrian Regional Planning Act provides the opportunity for municipalities to draft sectoral concepts, such as energy strategies, as contributions to the spatial development perspective on the local level. In the frame of a pilot project (from April 2016 until June 2017) a new guideline for municipalities has been developed to give recommendations regarding the content, the methodology and the implications of these energy strategies. The broad implementation of the guideline in the Styrian municipalities, however, depends on the availability of a spatially and factually highly differentiated database which represents the energy and climate related status quo on the local level. The main target of the project is the design and build-up of a Styrian geo-database (to be integrated into GIS Styria). It delivers an extensive picture (“opening balance”) of the structural data considering all kinds of land use and mobility as well as of total energy consumption, heat density and greenhouse gas emissions (on the level of the municipalities and on a 250m-grid). Furthermore, the geo-database consists of potentials of renewable energy sources available on the local level. The opening balance can contribute to a more efficient propagation of themes connected to “energy transition and climate change” into the public discussion. Moreover, it will foster awareness raising of the (specialist) public and of decision-makers in economy, administration and politics. The knowledge base concerning energy consumption and greenhouse gas emissions can penetrate various energy and climate related fields of action such as spatial planning, development of infrastructure, drafting strategies on energy transition and climate protection, and preparation of mobility concepts. The countrywide development of the opening balance is followed by a phase of instruction, advice and evaluation. This phase encompasses activities to introduce the needs of integrated spatial and energy planning and the guideline for energy strategies. Furthermore, workshops are offered to support spatial planners on the local level in the practical application of the guideline and the opening balance. The final step of this project phase is an evaluation and possible adaption of the guideline and the geo-database. The coaching of the spatial planners on the local level intends to initiate a learning process covering spatial, mobility, energy and climate related topics.

The considerable need for action in energy and climate politics emerging from the obligation to attain the international climate protection targets as well as national strategies for the energy transition and climate change raises the question to what extent cities and municipalities can contribute to a reduction of energy consumption and greenhouse gas emissions. So far designing strategies on the scale of municipalities for a better integration of energy and climate policy premises were hampered by the lack of comprehensive data on the current situation regarding energy consumption and greenhouse gas emissions on local level. The aim of EnCO2Web is the development of a spatially differentiated database on local level, which delivers an extensive representation of the energy-relevant structural data as well as of total energy consumption and greenhouse gas emissions of all Austrian cities and municipalities considering all kinds of land use and mobility. The visualisation of the database generated within EnCO2Web targets at providing comprehensive information for decision makers in various disciplines of administration and politics and for the specialist public as well as at generating a sound basis for evaluating development scenarios with respect to their impact on energy, mobility, and climate The broad methodological approach of EnCO2Web is based on a well-balanced consideration of all kinds of land use including housing, agriculture and forestry, commerce and industry, as well as services. At the same time a consequent differentiation of the energy consumption with respect to energy sources and application is provided. The comprehensive survey covering all municipalities ensures that the total energy consumption of each county is indeed reflected by the corresponding energy budgets on local level. Specifically, the capture of the mobility-related energy consumption and the resulting greenhouse gas emissions on the scale of individual municipalities to account for the special conditions of each city and municipality is underlined. The main focus of EnCO2Web is on modelling the daily passenger transportation considering each municipality as place of residence, as place of work and education and as place of customer-centred services. As a result of EnCO2Web an extensive open access geo-database with highly differentiated statements on the energy consumption and greenhouse gas emissions to be made on the level of municipalities will emerge. The visualisation of the database (including the development of integrated web-services) is supposed to ensure a broad application of the project´s findings and to meet the requirement of communicating complex facts in a user-friendly and interactive way. In future the knowledge base generated within EnCO2Web can contribute to a more efficient propagation of themes connected to “energy transition and climate change” into the public discussion and it can penetrate various energy and climate related fields of action such as drafting of strategies on climate protection, preparation of energy and mobility concepts, spatial planning, and the development of infrastructure.
