About the team
Team EFdeN represents Romania in the Solar Decathlon for the third time (SDE 2014, Versailles & SDME 2018, Dubai). Our team’s name comes from the mathematical function of N – f[N] -, where N represents nature. So it stands to reason that everything we do is according to nature, with no compromises. The team members are mainly students of the ”Ion Mincu” University of Architecture and Urbanism (lead university), Technical University of Civil Engineering Bucharest, Politehnica University of Bucharest and the University of Bucharest.
According to the United Nations Department of Economic and Social Affairs (2018), the percentage of the population living in cities will increase from the current 55 percent up to 68 percent in 2050. Correlating this data with the global population growth (7.7 billion now and 9.7 billion projected for 2050) and the increasing threat of climate change, one can identify a growing need for better, more efficient cities.
The urban environment is a huge consumer of resources, being responsible for 75 percent of energy consumption and 80 percent of CO₂ emissions globally. Sustainable building and city optimization are crucial goals on a local, European and global scale. For our team, Solar Decathlon is much more than designing and building a solar house. It is an opportunity, a possibility for students to gain valuable experience, for companies to start or continue investing in sustainability-oriented actions, for the general public to gain access to information and for the young generations to grasp the importance of responsible consumption.
The most important message we are trying to communicate is not attached to any particular project, but more of a general note that guides our endeavours. Sustainability is not rocket science, it is relevant, important and achievable by anyone. It is not for the rich, it is not for the sophisticated, and everyone should care and do more in this regard.
Team EFdeN is ready to tackle the most important challenge so far – design & build a solar-powered, resource-responsible, energy-efficient and eco-friendly building prototype that addresses urban issues not only in Romania or Germany but on a global scale. We aim to create a unitary entity between humankind, technology and nature by revising the connections between them through design while changing the focus from the traditional household and family structure to a new growing trend – single living.
To achieve this, we propose an innovative housing model based on the cohabitation between people that are embracing an independent lifestyle. Our concept will focus on creating mutually beneficial relationships within a community by maintaining the balance between private and shared spaces. The building will be a plug and play framework that will offer the possibility to be upgraded over time, in terms of space and technologies. We go beyond designing an efficient building to increasing attractiveness of sustainable practices for the wider public.
All buildings must be net zero carbon by 2050 to meet the goals of the 2015 Paris Agreement, yet fewer than 1 perent of buildings are today. Bearing this in mind, one of our project’s main goals for this competition is to develop a comfortable, affordable building, with a zero carbon footprint. Carbon emissions of a building can be easily divided into two main categories, operating footprint and embodied carbon.
Concentrating merely on carbon emissions generated during the usage phases of the building life cycle is not a rigorous approach. To increase the accuracy, it is mandatory to have precise data on the energy used for materials, construction and demolition. The purpose of the building design is to provide a pleasant, comfortable interior environment by shaping different technical and architectural features into a coherent design language. Our project’s focus will be to ensure these comfort conditions for both targeted generations while maintaining high energy efficiency.
