The extra efforts made by Radboud University to conserve energy led to the achievement of a number of new records in 2019. Gas consumption decreased by 24%, the campus solar panels generated a record level of solar energy, and underground thermal energy storage accounted for a larger proportion of the heating and cooling provided in our buildings. Sustainable energy increased to 28% of total energy use in 2019. Drinking water consumption decreased by 10%.
Targets and results
The university’s most important energy target is to achieve an absolute energy conservation rate of 2% per year. There’s also a 2% conservation target for drinking water. Both of those targets were comfortably achieved in 2019. These strong results are mainly a result of:
- the completion of the Hybrid Energy Grid
- the modification of heating and cooling systems
- several LED lighting projects
- measures to conserve drinking water in laboratories
