About the team

The team of the HFT Stuttgart consists of the following four groups: Core team, support team (HFT employees from research and administration), mentor team (professors at the HFT) and a partner team. Now, the core team consists mainly of students of the construction-specific subjects, such as Climate Engineering, Architecture, Building Physics and International Project Management.

Our motivation

At the Solar Decathlon Europe 21, the coLLab team of the HFT Stuttgart is working on an extension of the existing campus, the building 5 in the city centre of Stuttgart. As an innovative university, which will also be part of the IBA27, we would like to play a pioneering role in how urban densification can become a cost-attractive solution by incorporating regenerative energy generation and the use of ecological building materials.

The central project goal is the development and construction of innovative building units. In the name of climate change, they should promote the energy revolution in urban quarters. At the same time, the building units should be an example of sustainable inner-city buildings worth living in.

Our motivation

Project description

The aim of the project is to develop an adaptable, interdisciplinary extension and redevelopment concept for building 5 of the HFT campus, which addresses all ten disciplines of the SDE21. Based on this claim, an architectural concept will be developed that enables student working and living in a tiny space. Private space requirements are kept as small as possible, and flexible areas are available for communal use. By opening the building to the outside, the connection to the campus is strengthened, and networking areas are created.

As far as possible, only natural, recyclable or deconstructable and light materials should be used. For example, the basic structure of the building will be made entirely of wood. By using purely natural building materials and mechanical instead of glued connections between the building components, the emission of pollutants into the living space after completion is reduced to a minimum. Since flexible use and the possibility of transport are required, a modular structure is the best option.

The climate concept is based on the principles of natural/free ventilation and cooling and uses the thermal mass of the existing building. The aim of the concept is the interaction of energy-saving and regenerative energy generation to achieve a positive overall energy balance for the extension and the existing building.

Regarding the functionality of the house, it is important to ensure accessibility in the existing building as well as in the extension. The variable and modular living space concept allows for adaptability to different living situations. Affordability will be a priority for the planned housing. Besides, the quality and load-bearing capacity of the existing building is to be increased by the vertical extension. A high degree of prefabrication of the components will enable the minimisation of construction costs.

Urban mobility should be fundamentally reconsidered in our concept. The focus will be on the evaluation of different shared mobility concepts and alternative mobility in the form of new means of transport. By minimising private areas and opening to the neighbourhood in the planning, space for communication is to be created. The solar architecture of the vertical extensions is designed to be particularly striking and fascinating for the public.
