Significant energy savings achieved on the EPFL campus in 2016

The energy optimization measures implemented in 2016 by the Real Estate and Infrastructure Division resulted in savings of 2 GWh of energy and avoided the emission of 100 tons of CO2.

The projects that led to these savings are varied and have been carried out on several buildings. They concern technical infrastructure. This involves replacing some obsolete equipment, improving the operating principles of the systems, and modifying certain settings to better meet the needs of the premises and users.

Energy has been saved in the form of heat, electricity, and cooling water. Converted and calculated into total energy, this means that 2 GWh have not been consumed and will not be consumed in the following years to come.

Two projects illustrate particularly well the results obtained through these approaches.

Improvement of the operating principle of ventilation for the SwissTech Convention Center (STCC)

With two years of retreat on the operation of the TCCS and in consultation with users of the building, the operating principles of the installations have been optimized. This not only led to a 30% reduction in the electricity consumed by the technical facilities of the congress center but also improved the general comfort of the building.

Suitability of ventilation flows

The ventilation rates for a selection of AI building rooms have been adapted to better meet the needs of laboratories and users. This results in significant savings in heat, electricity, and cooling water. Established in May 2016, these adjustments will lead to even more savings in the years to come than those already observed last year.
