Projects / Cooperations
-
MPowerDATI-pilot
In MPower, the needs and questions of critics and the silent majority on the energy transition are recorded and answered with the help of communication formats. -
ReACD
The ReACD project focuses on improving the cyber security level of small and medium-sized enterprises (SMEs), start-ups and craft businesses. -
KIARA
The aim of the project is to develop and implement an innovative, AI-based AR learning application for the common good based on the easyARguide. -
DIY Energiewende
DIY Energiewende is a participatory project that, together with the WAJ multi-generational house, is developing next practices for a community-led, sustainable energy supply in housing projects by empowering residents to actively participate in the energy transition and take responsibility for sustainable energy consumption across generations through balcony solar systems, energy monitoring and co-creative educational formats.
