The urban development project aspern – Vienna’s Urban Lakeside is a large-scale implementation of the Smart City approach in Austria. The development is meant to show how tomorrow’s cities can function in an energy-efficient and climate-friendly way. As part of a flagship project a system-tuned strategy is being worked out, covering buildings, the power grid, users and ICT facilities.
The results are being integrated in a testbed made up of blocks of flats, a student hostel, a kindergarten and a school building. Findings from the project will be used to improve methods of managing and controlling buildings and power grids, while new facilities for user interaction are developed. The research results are applicable not only to individual buildings or Vienna’s power grid, but to entire urban districts all over the world. In the testbed buildings smart meters will record electricity consumption in detail, and other data, such as room temperature and indoor air quality, will also be collected; on this basis it should be possible to identify various “energy types“ as the Smart Users of the future.
The aim is to permanently improve user behaviour and limit power consumption by means of goal-directed information, new services and structured incentives. Dynamic tariff models from the electricity suppliers, for example, are one possible technical element in this. The project is intended to reveal which system solutions customers will accept.
Integrating intelligent buildings in a Smart Grid is another area of interest. Real-life data are used to investigate how buildings and clusters of buildings can bring their power surpluses to the electricity market profitably. For this a Building Energy Management System (BEMS) is needed in the building, communicating with a so-called Energy Pool Manager. For example a power supplier could act as an interface between buildings and the electricity exchange.
For buildings to take part in the electricity market Smart Grids and dynamic (time-variable) tariffs will be needed, to make selling surplus power commercially viable.
