Techathon 2022 Sustainable Building
You are studying architecture, mechanical engineering or civil engineering and want to advance the topic of sustainable construction in Aachen? From 07 to 10 November 2022 we show you how you can combine applied research and development with entrepreneurship in four days at the pulse of time and advance your career at the same time!
Together with innovation-driven companies, we are organizing the Techathon 2022. In four days, transdisciplinary teams will develop sustainable concepts for buildings together with colleagues from the companies.
Each of the participating companies will bring you a unique problem. The topics range from the development of reusable wall modules for reuse with the Lindner Group to passive and sustainable ventilation systems in rainy but hot Aachen summers with Viessmann. The cooperating companies and sneak peaks into the tasks will be announced bit by bit in the coming days.
You want to push the topic of sustainable building? This is your opportunity to do so!
At the end, all teams will present their solution to a jury of representatives from the companies and RWTH in a final pitch. The team that convinces the most will receive a special prize, such as a paid visit to the company's site.
Who are we looking for?
You and your friends. It doesn't matter whether your interests lie in mechanical engineering, architecture, civil engineering or comparable disciplines. The important thing is that you are motivated to develop new and creative solutions to tricky challenges. In the next few days, the companies and use cases will be presented on the social media channels of RWTH Innovation and the Machine Tool Lab.
How can I be part of it?
Here you can access our application form, where you can provide your contact details and upload your CV. In addition, we have three short questions for you.
Application deadline: 30.10.2022
Old pipes, new task - How can an innovative ventilation system "recycle" the hydraulics in the existing office building?
Radiator heating systems are the standard case in Central Europe when it comes to heating office space in winter. Their flow temperatures are usually around 70°C.
On the way to greater energy efficiency, heat pumps are increasingly being used as innovative heat generators whose flow temperatures are significantly lower. Under these circumstances, however, radiators are often no longer the optimal solution for heat transfer.
In addition to the heat generators, better building insulation, e.g. after renovation work, changes the heating load; at the same time, warmer summers increasingly result in a cooling load. Due to the airtight building envelope, the natural air exchange is so limited that a mechanical ventilation system must be used.
Under these challenges of Building 2.0, solutions are to be developed that combine ventilation (supply and exhaust air) with the sustainable idea of continuing to use hydraulic lines in existing buildings.
For this purpose, advantages and disadvantages of existing devices (e.g. parapet ventilation device, ceiling induction device, ...) will be worked out for the present case and a novel concept will be developed.
Finally, the design will be evaluated under technical (dimensioning), eco- and ecological (sustainability) and design (office space, building integration) aspects.
We are looking for...
Creative minds without preconceptions for solutions
Motivated doers for changes in the building
Smart concepts with fresh air
"Let's co-create living spaces for generations to come."
Think solutions that embody the aspect of "Design for Disassembly" to enable circular construction and building-independent use of finishing systems under economic and ecological aspects.
What do LEGO bricks have to do with a sustainable building techathon?
Quite a lot! LEGO bricks are a good example of "design for disassembly," one of the key
Key strategies for circular building. In the use case, the revitalization of Theaterstrasse with ceiling systems, system walls and raised floor systems will be considered and the technical possibilities as well as connections for building-independent use will be analyzed.
Buildings and system products are to be designed in such a way that they can be easily
disassembled and reused in the future. With LEGO, this is achieved through uniform connections: a wide variety of structures can be created at will, disassembled again and reused without damaging the material.
Assembly and disassembly are to be analyzed in terms of economic and ecological effects, and possible solutions are to be developed. Economically, the three areas of labor costs, i.e. personnel costs for assembly and disassembly, storage costs and material costs are to be considered with regard to material wear during the period of use, or necessary material replacement during conversion. The ecological consideration takes place on the basis of the evaluation of the GWP (Global Warming Potential), by means of the CO2.
The considerations are carried out on a real project with the aim of finding out how planning and execution processes should develop in the future.
We are looking for...
Visionaries and optimists for the future who are interested in rethinking and implementing circular construction in terms of economic and ecological impacts. The construction industry is facing a transformation, away from finite linear production and use, towards a circular regional economy in order to create sustainable, future-oriented living, working and housing environments.
