The paper describes the Smart Energy Supply Conception for the northern part of the urban development area aspern Seestadt in Vienna. It illustrates concrete options and potentials by different scenarios for the actual implementation of a future innovative energy system. The final conception was elaborated in the framework of a research project (Transform+) in cooperation with local key stakeholders and experts in the field of planning and energy research, public administration, including Vienna´s energy supply company and the responsible development agency. With the transformation of the former airfield of Aspern, the city of Vienna aims for a new quality in urban development, providing a new urban area with major central functions which is supposed to stimulate neighbouring quarters as much as the way urban development is being done in general. One of the main priorities in this context is the strive for high quality of life for future residents, combined with the important aspect of affordability. The masterplan foresees the development of a multifunctional area with a mix of residential, office, scientific, research and educational uses. By 2030, the area of aspern Seestadt (223 ha) shall be developed for 26,000 residents and offer 23,000 jobs. The masterplan for aspern Seestadt as well as the activities and measures set by the development agency Wien 3420 Aspern Development AG have been guided by the vision of an ecological, resource-friendly and climate neutral city from the beginning. This aim is also in accordance with the ‘Smart City Framework Strategy of Vienna’ passed in 2014 after the start of the implementation of aspern Seestadt (first phase). Within the context of the project Transform+, different options for a smart energy supply have been elaborated for the second implementation phase of urban development, named aspern Seestadt North. Here, in an area designed for 7,000 new apartments and 14,000 jobs, it was the main challenge to take the step from research on innovative future energy systems to a complete roll-out in an urban area to be developed in near future. In order to estimate future energy consumption (heating, cooling, electricity) and different options of energy supply and local renewable energy production, several ‘smart city’ scenarios were elaborated and compared against a ‘business as usual’ scenario. An important component in all ‘smart city’ scenarios is the share of renewable energy, for which a quanti¬tative target has been defined in the Smart City Framework Strategy for the city of Vienna (50% until 2050). To contribute to Vienna´s Smart City aims, aspern Seestadt North should strive to gain a high share of its energy from locally available renewable energy sources and also offer high flexibility to make use of additional sources (e.g. from potential future waste heat) in a later phase of implementation. In addition, total energy consumption and according CO2 emissions were critical factors for defining the final energy system configuration of the ‘smart city’ scenarios. As result, the elaborated ‘smart city’ scenarios show considerable potential for reducing energy consumption and significantly higher shares of renewable energy use compared to the ‘business as usual’ scenario, and therefore greatly reduced overall CO2 emissions. By implementing the ‘smart city’ scenarios, total energy consumption could be reduced by 39% against technical standards as in the ‘busines as usual’ scenario. Due to a higher use of local renewable energy supply the best ‘smart city’ scenario shows an overall CO2 emission reduction potential of up to 75%. Through the intensive cooperation process of the research team and the key stakeholders responsible for the development of the area, the Smart Energy Supply Conception laid a solid foundation for the relization of innovative future energy systems in aspern Seestadt.
