In 2009, the Energy Plus House promoted by the German Ministry for Transport, Building and Urban Development provided an example of the potential for sustainable building around solar technology. For a number of months in 2009 the home was on display in numerous cities around Germany to highlight the advanced technology. The house was the brainwave of students at the Technical University of Darmstadt, led by Professor Manfred Hegger. Stiebel Eltron provided the ventilation equipment within this house.
Many buildings in Germany are now home to efficient and future-proof heating technology based on renewable energies. Within Australia, Stiebel Eltron has released a number of ventilation solutions for low energy and passive houses.
