• Legal requirements are increasingly demanding more sustainability in IT, including in the university sector. However, the implementation of green IT measures is often hampered by a lack of financial incentives, outdated technical structures, staff shortages, and acceptance problems.

However, the implementation of green IT measures is often hampered by a lack of financial incentives, outdated technical structures, staff shortages, and acceptance problems. The project »Green Academic IT Potential (GAIT)« addresses these challenges by creating transparency about energy and resource consumption and promoting a change in awareness at all levels. With the help of key figures and measurement systems, the ecological impact of IT decisions is to be visualised, and sustainable measures introduced in a targeted manner. The most important results include the prioritization of measures such as server virtualization, the introduction of video conferencing systems, and the use of energy-efficient hardware. The follow-up project bwCloud 3 transfers these approaches to cloud services in order to tap into further savings potential and promote sustainable IT decisions. Transparency regarding the use of resources remains a key success factor, even if its implementation is sometimes time consuming.…
