Buildings as Interactive Members of the Smart Grid – Design and Construction

The ever increasing share in suppliers of renewable energy is accompanied by an increased integration of volatile decentralised suppliers (wind turbines, PV-plants, combined heat and power plants) into the grid. The limited capability to predict wind flows and solar radiation hinder the integration of fluctuating suppliers into the grid while simultaneously guaranteeing high quality of energy supply. Furthermore, the consumers are turning into “prosumers” by changing between production and consumption. This leads to the necessity that energy suppliers have to take advantage of peak load plants in order to provide power reserves and balancing energy. These difficulties are further aggravated if they occur on a local level. The necessary expansion of supply and transport infrastructure is both resource and cost intensive. The system is designed for peak loads and its dimensioning is therefore generally suboptimal.Demand side measures can be a relief for these problems. Buildings account for 30% of the loads and are therefore one of the largest consumer groups. Hence, the buildings and the households still hold vast amounts of untapped potential and are therefore in the focus of this pilot project. Load management (e.g. consumers in buildings and households) can provide a targeted relief for the low voltage grid. Furthermore, the feed-in of decentralised and fluctuating suppliers are favoured. Therefore it is absolutely essential that buildings are considered as parts of a system and to plan and implement them in a grid-friendly way, accordingly.

The focus of the project is the optimal system integration of the buildings into the Smart Grid (load management in combination with decentralised, renewable generation, including controlled charging of electric vehicles). In this project it is possible to intervene for corrective actions for the significant parameters by scientific planning support early on and right from the outset of planning. For the realization of the SGMS-HiT-pilot project, the project „Wohnen der Generationen – Rosa-Hofmann-Straße“ (145 apartments for different users from young families to elderly persons) to be built by Salzburg Wohnbau and other property developers in Salzburg-Maxglan, was selected. Planning work will begin in autumn of 2010, onset of construction works will start at April 2012. From Dezember 2013 on, the Smart Grid-optimised pilot building will be available for demonstration purposes.
