  Students Copyright: © RWTH Innovation GmbH The Techathon with four innovation-driven industrial companies offers you the opportunity to work in a team on extraordinary tasks, solve problems and make contacts in the industry.

How?

The Techathon with four innovation-driven industrial companies offers you the opportunity to work in a team on unusual tasks, solve problems and establish contacts in the industry. For four days, you and your team will work together with colleagues from the companies to develop sustainable concepts for the continued use of a vacant building in downtown Aachen.

Who are we looking for?

You. It doesn't matter if your interests lie in mechanical engineering, architecture, civil engineering or entrepreneurship. The important thing is that you are motivated to develop new and creative solutions to tricky problems.

What are the tasks?

Each of the participating companies will bring you a unique problem. The topics range from modular interior design for flexible (re)use of co-working spaces to passive and sustainable ventilation systems in rainy but hot Aachen summers. We will gradually announce the collaborating companies and sneak peaks into the tasks in the coming days.

How can I participate?

You can find our application form here. There you can enter your contact details and upload your CV. In addition, we have three short questions for you.

Application deadline: 30.06.2022

I am ready, when do we start?

Before we start with the content, we would like to get to know you! For this purpose, we will prepare you for the next days at noon on the 4th, including a joint evening event. From the 5th to the 7th of July, you will design, puzzle, and innovate for all you're worth. On Friday afternoon, the stage belongs to you when you present your solution to our expert jury.


 

Use Cases

Viessmann Case

Your goal:
Old pipes, new task - How can an innovative ventilation system "recycle" the hydraulics in the existing office building?

Your task:
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 higher 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.
The design will finally be evaluated under technical (dimensioning), eco- and environmental (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."
 

Lindner Case

Your goal:
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.

Your assignment:
What do LEGO bricks have to do with a techathon on sustainable building?
Quite a lot! LEGO bricks are a good example of "design for disassembly," one of the
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.

Viega Case

Your goal:
Vision and concepts of Augemented Reality use cases for heat and potable water supply in residential and non-residential buildings.

Starting point:
Maintaining drinking water quality is Viega's core competence. Our activities in this
in this area therefore goes far beyond the development of products and the
and the use of the right materials. Drinking water is a particularly precious
and not for nothing one of the most strictly controlled foodstuffs. For this reason
we also support our customers with extensive service and seminars to maintain the
maintaining the quality of drinking water. When it comes to implementing the knowledge gained
our innovative solutions come into play.
In doing so, we always want to develop further and look at technologies and methods that will enable us to offer innovative products and services in the future as well.

In this context, we want to work out visions and concepts how augmented reality in the field of heat and drinking water supply can offer added value for building participants (project developers, planners, craftsmen, ...) and end users in the future. For this purpose, potential pain points or customer needs are to be identified. What do potential solutions look like? Which technical systems are necessary for a solution? What information is required? What does the information flow look like? Are there already existing solutions on the market?

A Microsoft Hololens 2 will be provided to the team for the elaboration.

Rough task overview:

  • Familiarization with the Microsoft Hololens 2
  • Creation of a rudimentary building model of the venue in Autodesk Revit.
  • Development of potential use cases and adaptation of the building model if necessary
  • Conceptualization of relevant process chains regarding model information etc.

We are looking for:

  • Creative minds
  • Fun with digital topics
  •  Clever and analytical entrepreneurs who can draft a business plan and conduct a market analysis.
  • Engineers who can design implementation concepts and flowcharts.
