Initiative 1000: "Switch Smart"
In the 2014/2015 fall semester, the University launched Initiative 1000 with the goal of saving 1,000 megawatt hours of electricity in six months. The Initiative met the goal. That led to a repeat for the 2015/2016 fall semester, with another 1,000 megawatt hours savings goal and an added 1,000 megawatt hours of saved heat. These ambitious goals were also achieved.
Here are some of the publicized electricity-saving tips:
- Turn out the lights
- Shut down the PC after use
- Turn off the experiment after ending the test series
- Use power strips with on/off switches
And here are a few of the heat-saving tips:
- Turn down the heat
- Report defective radiators
- Use purge ventilation instead of constant ventilation
- Keep office doors closed; hallways typically are not heated to the same degree
Project "Change": Be energy-conscious
The engergy-saving initiative "Change - be energy-conscious" launched by Energy Management in the Engineering and Construction Division is aimed at University of Stuttgart students and staff members. With helpful tips that are easy to implement and easily fit into daily life, heating energy use was to be reduced by up to nine percent and electricity use was to be reduced by up to 18 percent.
The Project Change was a cross-disciplinary collaborative project that ran from 2008 to 2011 as part of the “From knowledge to action – new paths to sustainable consumption” socio-ecological research program under the aegis of the Federal Ministry for Education and Research.
The University of Stuttgart for the first time was able to save 10% heat energy during the first year. The projected goal for electricity saving was not achieved at the time.
Saving energy with energy performance contracts
In recent years, the University’s Energy Management office entered into several energy-saving performance contracts whose object was, among others, rehabbing many of our ventilation systems and their controls. To date, nine contracts have been let, of which four have been successfully completed. With the current contracts involving total investments of more than 13 million euro, the University is saving roughly 2.8 million euro annually in energy costs, (savings which, incidentally, are used to repay the contract borrowings.) That represents approximately 30% savings on heating or cooling and 6% electricity savings.
All our active contracts to date have achieved their objectives; in fact, they bettered the contractual forecasts by some 10% on average.
