Edux delivered doors to the Aurinko-Tuulia zero-energy house that was constructed in 2012 by Kymppitalot at Tampere's Housing Fair. A starting point for the project was to minimise heat loss, so that the house could produce all the energy it needed. The house meets all the requirements of the future and its energy need is one-third compared to a conventional house of the same size. This was enabled by e.g. Edux's top insulating doors.
