Building overlap energy, Seatown Aspern

Forschungsförderungsprojekt
¿Seestadt Aspern¿ has the goal to become an international landmark in the construction of energy efficient and sustainable residential areas. In order to design and develop Seestadt Aspern at the leading edge of science and technology, Wien3420 coordinates the FFG framework project ¿Aspern ¿ die Seestadt Wiens¿. Within this framework, basic investigations will be carried out in the themes ¿outdoor space and local climate¿, ¿Inter-building energy distribution (Gebäudeübergreifende Ener-gie)¿ and ¿energy consumption monitoring¿. A major point in the framework will be the construction of demonstration buildings, in which the results of the above mentioned projects regarding energy producing buildings and their integration into a local energy distribution network shall be imple-mented in order to prove feasibility and thereby to attract the interest of investors, construction in-dustry and utility companies. The proposed subproject ¿Inter-building energy distribution (Gebäudeübergreifende Energie)¿ will in the first step pursue the goal to support the construction of the demonstration buildings by investi-gating the options of local energy exchange among the user groups ¿residential, office and produc-tion¿ and delivering the related findings in-time to the planning teams of the demonstration build-ings. In the second step, the further development of the whole Seestadt Aspern shall be supported by the development of a prototype of a residential area simulation. This shall on one hand allow the derivation of a roadmap for the development of the local energy distribution networks and on the other support the land developer (Wien 3420) to identify the most appropriate integration of indi-vidual construction projects into the local energy system. For this purpose, the project will be struc-tured along the following themes: Analysis and modelling of the possibilities of local exchange of thermal energy (district heating). Here, the following aspects will be considered: Network losses as a function of system temperature, electric energy demand for pumping, exergetic optimisation, prognosis data and economic efficiency. Analysis and modelling of (local) exchange of electric energy. This work will consider the following aspects: Influence of all consumer groups (buildings, street lightning, charging stations for electric vehicles etc.) and producers (PV, wind, etc.) of the residential area, scalability of the distri-bution network as well as optimal use of the local exchange within building, residential block and area. Analysis and modelling of the interaction between network infrastructure and building, this activity will investigate the following aspects based on the simulation of individual buildings: Discrepancy between individual optimisation (of a building, of a sub aspect e.g. overall heating de-mand) and overall optimisation of the external energy demand of the residential area as well as the relation between city planning, placement of buildings, building density and the local energy net-work. Analysis of the regulatory constraints: first, for ensuring the feasibility of the demonstration buildings (ensuring compliance with existing regulations) second, for the future development (sug-gestions for the adaptation of existing regulations). The model based, holistic view of these elements on a residential area and the consideration of the use of electric vehicles constitute the innovative step of this proposal compared to prior projects.
