We built our second model!

It represents the unity of our design, which we will also be building in Wuppertal next year: our demonstration unit.

On Wednesday we brought the model to Wuppertal in the Alte Glaserei, where it can now be seen together with our first model, the addition of Café Ada, in the Solar Decathlon pre-exhibition.

Starting the built of the architectural models

Have you seen? 👀

We are currently building two architectural models that will be exhibited in Wuppertal and evaluated by the jury.

SDE21 Boxen für Transport
Built of the transportation boxes.

The first model shows the urban situation around Café Ada as well as our design for a sustainable building addition.
The second model shows our House Demonstration Unit. We will later implement and operate the demonstration unit on a 1: 1 scale for the finals in Wuppertal.

Deliverable D#3

Right on time for the start of the summer semester, we mastered the third milestone in the competition. We further developed the building concept, created high-quality visualizations and built the first practical implementation in form of an urban model.

After more than a year of project duration, we are now moving forward with rapid strides. Technical and organizational foundations were laid, which enable the increasingly intensive and extensive project work. The focus is now on deepening special topics.

We therefore visited Wuppertal again to revise our imagery and to take specific recordings of the Mirke quarter and the Ada café.

With the completion of the design phase, things will now become concrete. In terms of planning, this means that we will work on the work planning for our demonstration unit by the summer. Here, the interdisciplinary cooperation between individual courses is essential.

In addition, we will create two architectural models by the summer: an urban model of the building design on a scale of 1: 100 and a model of the demonstration unit in 1:25. For the model of the building design, the area has already been modeled and built.

In order to be prepared for the final in 2022, special planning is already underway for the next few months. This applies to topics such as occupational safety and construction site logistics.

Deliverable #2

Another milestone has been achieved: Last Thursday we successfully submitted our second Deliverable (D#2) in the Solar Decathlon Europe 21 competition.

As part of the submission, we also made a film:
Our first “image film” was shot in the communication seminar under the direction of Johannes Riedel. The animations of our building were created in the course of Felix Löhr’s master thesis.

The film clarifies the concept for our competition entry and shows a great development of the building design and the demonstration unit compared to the first deliverable.

In addition, the appearance of the X4S team also evolved. Under the motto “One logo, one team. Ten colors, ten disciplines ”we are now starting with our new logo and our own Instagram account.

For the coming months, we will be working on our design in the areas of architecture, statics, energy, building physics, the model construction of the entire building, as well as the implementation planning of the demonstration unit … and of course our third deliverable, which is due in mid-March. After the deliverable is before the deliverable 😉

Creation of sustainable cities also a topic of Mayor Zeidler

Team X4S at Biberach University of Applied Sciences receives great support and encouragement from the former athlete and current mayor Zeidler. Every day he is also involved in sustainable living and building as well as the establishment of sustainable and liveable cities and recognizes the necessity of rethinking.

With the designation of the “Allrounder” he wishes Team X4S the success of the solar decathlon.

Team X4S would like to thank for the great video message and the support of the municipality of Biberach for participating in the sde21 competition.

Competition final is postponed to 2022

Unfortunately, the Corona pandemic has not gone by unnoticed by the Solar Decathlon Europe 21. As this competition is based on external sponsorship money and the processing of competition entries has only been possible to a limited extent in recent months, the organisers have decided to take appropriate measures.

The competition, which was originally planned for September 2021, has now been postponed to June 2022. This extends the competition phase by three quarters of a year.

For us at Biberach University of Applied Sciences, the project postponement gives us the opportunity to work on some topics more intensively and we are already looking forward to being able to implement the results in reality soon. This means that we will be able to strengthen interdisciplinary cooperation and compete as a team.

Your opinion on sustainability

More than 160 students from various courses of study took part in our survey on sustainability.

Many thanks for your contribution!!!

The results show that the definition of sustainability is interpreted quite differently. Nevertheless, there is agreement that sustainable action is important, especially in the energy, mobility and housing sectors. The following chart shows your opinion on this issue.

We have summarized the evaluation of the survey in a short film and you can find it under this link:

Building addition in everyday life

While working on the competition entry, the addition and renovation, for which sde21 was created, we noticed that the topic of addition already has a small beginning. Where green space is valuable food, the garden area is also very limited and two long-eared families already live in ground-floor stables, space for more playmates becomes rare. However, if you take a closer look, there is a solution to this problem: we add to the existing stable, of course with recycled building materials to conserve resources.

In this way, without additional land consumption and with hardly any intervention in the existing structure, we make it possible for both the newcomers with the creation of high-quality stables and for the residents of the existing stock by upgrading the shell of the rabbit hutch.

And should the young family still grow, there is still room for improvement

Online survey on sustainability

Sustainability is an important part of our competition entry for the Solar Decathlon Europe 21, as our goal is to develop and implement solutions for sustainable, energy-efficient and socially responsible construction in urban environments. This is why we have chosen the team name “Extension for Sustainability” (abbreviated “X4S”).

Of course we are interested in how much importance our fellow students attach to sustainability and in which areas it is most important to them. We have therefore developed an online survey and look forward to your participation:
