project description
Due to the continuous increase in the number of students in recent years together with the construction of new buildings and the renting of additional space, the energy consumption of the university has increased significantly. The current aim to reduce the consumption level in the best possible way by means of energy-saving measures and the use of renewable energies, so that the university is CO2-neutral by 2030 in line with the CO2 target of the State Government of Hessen.
This goal is accompanied at the THM by the innovation and structural development funding of the Hessian Ministry of Science and Art with the funding line "Energy Efficiency Concepts" to increase energy efficiency in the Hessian university sector. As part of this funding, an energy concept to reduce CO2 emissions created at the university, from which effective measures are derived and implemented.
initial situation
The THM buildings in Gießen and Friedberg have a total area of approx. 118,473 m² (area type: NF1-9, as of 2022) and were mostly built before 1980. In recent years, the system technology has already been upgraded to a large extent, but many systems still have great savings potential due to their age and technical status.
For example, an energy management system was implemented in order to be able to display a central and building-specific recording of energy consumption in detail. By initiating study work to investigate energy supply and procurement at the university and by developing concepts for energy-related renovations as part of the ECO2 project, further ideas and measures are being developed.
project goals
In 2015 the heads of state and government from over 150 countries decided on a common goal to limit global warming to below two degrees Celsius. In accordance with this, the Hessian state government plans to organise it entire administration on a CO2-neutral basis. This is to be achieved through three fields of action: “reduction, substitution and compensation”. The Technische Hochschule Mittelhessen would also like to have a CO attached to this by 2030 2-have neutral operation and thus successively ensures greater energy savings, the expansion of electromobility and renewable energies.

energy concept
The energy concept is the basis for future planning of measures that are to be implemented in the short, medium or long term in order to reduce CO2-emissions from the university and increase energy efficiency.
It includes the following fields of action:
Current measures are mainly focused on minimising energy consumption. Due to the expansion of renewable energies at both locations, less green electricity is purchased from outside (since 2017, THM has almost exclusively purchased green electricity). Further substitution measures are planned for the future, such as the purchase of CO2-neutral biogas for heating the Friedberg site. The promotion of environmentally friendly mobility is being promoted through the expansion of bicycle parking spaces and the expansion of the charging infrastructure. In the future, the area of procurement as well as biodiversity and species protection should play an even greater role at the THM and gain in importance. The catalogue that has been developed includes 60 measures, one third of which have already been implemented. There are always new ideas arising, often inspired by employees and students.
