After almost three years of preparation, the time has finally come: The long-awaited hot phase of the international university competition SDE 21/22 begins with the construction of the prototype in Wuppertal. The coLLab team from HFT Stuttgart is making its contribution with an urban, ecological redensification and is thus entering the solar decathlon with 17 other student teams.

The construction phase begins in Wuppertal in May, and the award ceremony for the overall winner of the competition is on June 24. What is the mood like in the team? In which disciplines do we have the best chances? And how did we manage to motivate people to stick with it in this interdisciplinary project? Find out all this and much more in this interview with Annabell Gronau, responsible for project management/public relations and the interface between teaching and the project.

How can we create affordable urban living space, build sustainably, take climate protection into account, conserve resources and use renewable energies? The contribution of the team coLLab of the HFT Stuttgart tries to find answers to these urgent current questions with its competition entry at the Solar Decathlon 21/22 (SDE 21/22).

The final of the Solar Decathlon Europe will take place in Wuppertal from June 10 - 26, 2022. Detail presents selected contributions to the international university competition in advance in an online series. Today: the colLab project of the Stuttgart University of Applied Sciences (HFT).

Even during the lecture-free period, a lot of work was done. Students, staff and professors continued to work on the entry for the Solar Decathlon competition during the semester break and are looking forward to a new exciting semester.

A few weeks ago we submitted the HDU model and we think it turned out great! Between 17 July and 26 September 2021, our models are exhibited at the big Solar Decathlon Europe 21/22 pre-exhibition.

Last Tuesday, 6 July, we successfully delivered the 4th deliverable (DEL#4) out of a total of 7 in the Solar Decathlon Europe competition!

Annabell Gronau, Jonas Stave and Prof. Dr.-Ing Jan Cremers write about the need to create sustainable, affordable housing in cities, the design for the example building "Bau 5" and the possibility of transferring the addition of storey to other locations.

Our team members Svenja Herb, Yannik Zelenka, Annabell Gronau and Jonas Stave were guests on the M4Lab podcast and had the chance to talk. Listen in!

Annabell Gronau and Jonas Stave from Projekt coLLab delivered the model for the Design Challenge in Wuppertal. A short description of the project.

We planned, lasered and glued like crazy over a period of two months. The task was to complete the model for the Design Challenge, the first step in the submission process of the Solar Decathlon competition, on time. The deadline for the submission was Friday, 28 May 2021.

During the last weeks we have been working intensively on our model for the Design Challenge. Photos of the process and the final model.

This year, the nationwide Girls' Day took place digitally for the first time. The study programmes Building Physics, Mathematics, Climate Engineering as well as Surveying and Geoinformatics at HFT Stuttgart presented exciting and practical projects to the 25 participants aged 11 to 16. We also presented the project for SDE21»22.

In the subject Urban Mobility Concept, students of the Bachelor of Infrastructure Management and Bachelor of Civil Engineering work together on the development of a mobility concept. This is to be developed taking into account the extension concept for the SDE21, but also the overall mobility on the inner city campus. The goals are to reduce automobile traffic in the quarter and at the same time maintain the same flexibility and mobility for the residents.

At the University of Applied Sciences Stuttgart, a group of students from the architecture and climate engineering courses initiated competition participation in 2019 with the variant of adding storeys and renovation under the name "coLLab" (collaboration). A brief presentation of the project.

Since May 2019, the core team has been meeting on a weekly basis to exchange information, discuss challenges and tasks, and work on the ongoing development of the coLLab project. Despite the current COVID19 restrictions, these meetings continue to take place weekly and have been held online ever since.

In the elective courses Simulation Tools and Solar Heating and Cooling students work on the development of a technology concept.

In the subject Interior Design, students of the Bachelor of Interior Architecture work on a clever zoning and planning of the interior design of the room modules. The basis for this is the architects' design produced in the last semester. First of all, the subject creates design concepts from floor plans and concept sketches, and then constructively checks them in floor plans, sections and details.

Architects and civil engineers usually have to wait a long time before they are allowed to implement their ideas and create something concrete - at least until their first job after graduation beckons. For a group of students at the Stuttgart University of Applied Sciences (HFT), the dream is coming true sooner. As part of the international Solar Decathlon Europe competition, they are planning and constructing a building that should be as sustainable, energy-efficient and socially acceptable as possible.

In the winter semester 19/20, the project MAKE started to work on the Solar Decathlon Europe 2021. This project is a cooperation project between students of the courses Master of Architecture (MA) and Bachelor of KlimaEngineering (KE). The task was to develop a design for the extension for the Solar Decathlon.

In the elective subject SDE Design and Construction, students of the Master of Architecture and Bachelor of KlimaEngineering work together on the further development of the design. The designs created in the MAKE project in the last semester serve as the basis for this.
