6 Smart Building Smart City A smart city is more than a link of smart Buildings

7 Smart Building Smart City Smart city could be identified: smart economy smart mobility a smart environment smart people - Need of active citizen participation! smart living smart governance Need of: Intelligent Design process, management,.. and integrated information, communication technology

8 Smart Building Smart City Smart Buildings in Smart Grids Smart Grid: Decentralized Power Plant managed by Internet of Energy

9 Energy supply today central Gas distribution system Office building Electricity network megawatt power stations flexible? sustainable? factory oil

10 aim: decentralization of energy supply Smart Grids Smart Homes Smart Buildings E-Mobility Virtual power station
