What role does the topic of smart homes play with regard to implementing the energy transition in buildings? Johannes Hauck, Director of Corporate Business Environment, was asked this question in an interview with the association ZVEI (German Electrical and Electronic Manufacturers’ Association) at the 2016 Light + Building trade fair.
In Germany, buildings now account for 40 per cent of total energy consumption. Many people do not realise that the percentage is this high. However buildings are also where there is the most potential for energy saving. Professional renovations and the use of modern building technologies could result in energy savings of up to 80 per cent here.
So how can we achieve savings at this level? Firstly, the building’s energy consumption should be displayed transparently so that the use of electronic devices can be managed in a way that makes sense. Secondly, the routing of energy and, more recently, the storage of energy within the building also play an important role. For all of these measures to be effective, it is crucial to have building automation systems that create energy transparency and, if required, also perform certain functions.
A current example is the project ‘Forward-looking energy management at the research and application centre in Blieskastel’. This building at Hager Group in Blieskastel, which won an award in 2015 as part of the Germany-wide innovation competition ‘Excellent Places in the Land of Ideas’, makes energy savings of up to 20 per cent thanks to building automation technology such as temperature regulation and control. However, in spite of the fact that it is already highly energy-efficient – 90 per cent of the energy generated can be used in the building itself – Johannes Hauck says that there is still room for improvement.
