We are over 30 young and passionate students, from fields ranging from architecture, engineering, communication or management, and together we form the EFdeN team.
In 2014 we represented Romania in the final for Solar Decathlon Europe in France, alongside 19 teams from 16 countries and 4 continents. We attended 10 interdisciplinary events, from architecture to engineering, innovation and communication.
We designed and built an extraordinary safe and comfortable solar house, energetically efficient. The house is automatized, being 100% electrical, without monthly bills and environment-friendly.After many hours of work and dedication, the house became Romania’s First Center of Research for Comfort Conditions - EFdeN 4C.

If you had to do it again?
We participated with this house in the Solar Decathlon competition, in the 2014 edition. Because we had to transport the house to France and back, to Versailles, it had to respect a modular model. Based on this modular design, our permeability simulations didn't match with the real tests. That's why, next time, we hope to manage a more compact model, with as few joints as possible.
Also, the facade is made from 3mm ceramic plaques. During the construction stage, we discovered it is very breakable and thin, some of them being ruined either by transportation, either by bad handling.
Building users opinion
Our prototype is open for the public every Thursday and Sunday, and during special occasions, such as "Museum Nights" or during important visits. People were overjoyed by the concept of "The Futuristic House" and some even traveled from other countries to visit and see the new technologies and innovations. Also, some of our colleagues did an experiment, sleeping in the house for three days. The feedback was positive, the ability to control the lights and the heat coming in handy, as well as the modular design, describing the house "comfortable" and "feeling like a true residence".

It is a natural moss that is called Blue Mohito. It has not only aesthetic but also functional properties, absorbing moisture and gradually releasing it.
The moss was chosen for its functional purposes. Also, it helped our goal of increasing the green space per capita, integrating nature in the EFdeN house.

The external surface of Aspera Fenix Nanotechnology involves the use of nanotechnology and it is characterized by next generation acrylic resins, hardened and fixed with Electron Beam Curing process, opening up new avenues in the field of interior design. With low light reflectivity, its surface is extremely opaque, anti-fingerprint and features a very pleasant soft touch. Thanks to the use of nanotechnologies, Aspera Fenix Nanotechnology thermally heals any superficial micro-scratches, as its name indicates.
This material, with its power to regenerate, was greatly accepted and embraced by our members and our stakeholders. Being easily cleanable and its scratches self-healing, it respects our goal of reducing unnecessary household items in the EFdeN house.
