Public Relations Documents

The team “OnTop” from Frankfurt University of Applied Sciences (Frankfurt UAS) presented a combination of energy efficient construction method and energetic high performance technology with their contribution at Solar Decathlon Europe 2014. The aim of the competition was the further development of residential buildings that are supplied by solar power.

Twenty, previously qualified, international teams participated at the student competition in Versailles. The participants had to take the constructional and social requirements of their respective environments and regions into account.


The interdisciplinary team of Frankfurt UAS had worked out a concept that may be pioneering for growing large cities and metropolitan areas. To create more (living) space the prebuild “Energy-House” with a base area of 100m² is attached on top of an existing building. It is completely supplied by solar power and dispenses superfluous energy to the building below it.

Post compaction plays a great role in Frankfurt’s turnaround in energy policy. Free roof spaces and gaps between buildings are used because of this. The roof spaces of many apartment complexes from the 50s, 60s and 70s could be optimally used by the OnTop concept and would supply the buildings with renewable energies.The project was constructed in the Hessian Schlüchtern with the help of many sponsors who contributed either financially or materially to the student project. It was then transported to the competition finale in Versailles where it was exhibited for two weeks and presented by the students to visitors from all around the world. 

In the end the team got the 7th place in the overall ranking, the first place in the Social Housing Award, which was awarded by the European professional association CECODHAS Housing Europe, and the third place in the special category “Construction Management & Safety”.

The biannual Solar Decathlon Europe was initiated for the first time in 2010. The award is based on the American Solar Decathlon Washington which was initiated in 2002. The organizers were the French ministry for equal treatment of regions and housing, the French ministry for ecology, sustainable development and energy and the U.S. ministry for energy.
