In April 2018, GfR conducted an energy audit in accordance with DIN EN 16247-1 in order to analyze and improve the energy efficiency in the test laboratories and the administration. Under the direction of Dipl.-Ing. Siegfried Ruwe from Energie Consult in Münster an exact determination of all installations and devices was carried out. Although the analysis already showed efficient, targeted consumption, further measures were jointly defined. In particular, GfR will invest in technical and organizational measures in the areas of lighting, heating and pneumatics, which will further reduce energy consumption and thus have a positive impact on the CO2 balance and costs.
