Financial benefitsof smart buildings:

Lighting

Building automation and control systems

Smart buildings can feed self-generated energy back into the grid. In a smart grid, supply and demand are con-nected. Buildings can be used to store energy.

Bilateral exchange of data and energy between the building and the smart grid.

Buildings becomea key element of the smart gridA smart building with its own energy generation and storage interacts with the smart grid and is able to manage its own energy demand and generation to minimize energy costs and CO² emissions.

Smart building as a Prosumer consumes and produces power(photovoltaic, combined heat and power, wind, geo-thermal) on site.

The power systems in Europe have mainly been built to accommodate central power plants. This changes as more distributed energy resources are being introduced into the power system. Future smart grids need to balance generation and demand.

20%The EU aims to get 20% of its energy from renewable sources by 2020.
