Energy use & CO2 The University of St. Gallen consumes a substantial amount of energy. In order to minimize the CO2 emissions, HSG is continuously taking measures to optimize its operations. In January 2013, the HSG started the „CO2 Footprint Infrastructure: Measurement and Optimisation“ project to systematically monitor and reduce its carbon footprint. The project was launched after the student organisation oikos presented the first carbon footprint in 2010. The presidency of the university acknowledged the work done and integrated carbon management into the infrastructure and building services’ regular tasks. In December 2014, the project was successfully completed, with the objectives set even being exceeded. The results are shown in the table below where the energy savings and CO2 reductions for 2015 are compared with the results in 2013. Campus Gymnasium Gas (for heating) Electricity Gas (for heating) Electricity -10% -4% -22% -2% Equals savings of ca. 55'000 litres of heating oil 101'00 kWh 160 t CO2 ca. 5'000 litres of heating oil 5948 kWh 38 t CO2 Since the completion of the project, a cantonal target agreement has been implemented and now serves as the driving force and basis for further energy efficiency measures. For example, in the autumn of 2015 approximately 1550 fluorescent tubes in the B-building and the library were replaced with LED lamps. Another energy-saving measure includes all the computers in the PC laboratories being configured to automatically switch to energy-saving mode after 15 minutes of non-use and to switch off at 10pm – an easy and efficient way to save energy.
