Current energy situation
Sustainability is a central part of TU Darmstadt's self-image. It makes significant contributions to sustainability – with research projects and in studies and teaching, and at the same time through the responsible daily actions of its members. The responsible use of energy is also essential; it is climate protection in practice and an important contribution to sustainable global development.
During the last heating period, we jointly implemented numerous measures to save energy. We want to continue to build on these findings – to stabilize our energy consumption at a low level not only in winter, but all year round. Our aim is to reduce the energy requirements and climate-damaging emissions of our buildings as much as possible and to ensure a CO2-neutral energy supply for our university as quickly as possible.

Daily consumption of electrical energy
The graphs show the daily aggregated total consumption of electrical energy and heat at TU Darmstadt.
The graphs are updated every morning around 6 am.
Acting sustainably and using energy responsibly is something each and every one of us can do together. Thirty thousand members of TUDa can make a big difference together with small measures! Our actions not only protect the environment, but also the budget. Every euro that is not spent on energy is available for research, teaching and xchange - ultimately, this amounts to several million euros per year for TUDa!

May 08, 2025
Last winter, TU Darmstadt once again succeeded in stabilizing its energy consumption at a reduced level. Compared to the baseline period before the energy price crisis in 2022, all members of TU collectively saved around 17% heat in the 2024/25 heating period, adjusted for weather conditions. Electricity consumption fell by almost four percent compared to the baseline period.

TU receives first LEAF certifications for sustainable laboratories
February 11, 2025
Potential zum Energiesparen nutzen
At TU Darmstadt, four working groups from the Departments of Chemistry and Biology have been awarded so-called “LEAF certificates” for more resource-efficient laboratory operations. With these quality seals, the TU is a pioneer in Hesse.

Energieverbrauch der TU 2024 auf dem Niveau des Vorjahres
Januar 23, 2025
Die TU Darmstadt hat ihren Energieverbrauch 2024 auf dem Niveau des Vorjahres stabilisiert. Der absolute Verbrauch an Wärme und Strom lag nach Angaben des Energiemanagements um jeweils etwa zwei Prozent über dem von 2023. Im Vergleich zum Basiszeitraum – dem Jahr vor der Energiepreiskrise (Juni 2021 bis Juni 2022) – war der Verbrauch jedoch bei der Wärme absolut um 27 Prozent und beim Strom um sechs Prozent geringer.
TU Darmstadt wants to act sustainably. That is why we use energy responsibly. We can achieve this together if each individual makes a small contribution. At the same time, we renovate and use buildings in an energy-efficient manner. We base our measures on where we can achieve the greatest savings.
