In order to identify potentials of energy saving we carry out snap shot or long-term measurements. for e. g. of temperature or flow volumes in the field of heating. Results, as well as already existing data are taken into consideration during our computer backed analysing methods, which simulate seasonal cycles and identify energy saving potentials. For e. g., by utilizing our analysing tools we calculate energy savings through thermal insulations, improvements of hydraulic systems or optimisations of boiler houses due to reduced flue gas losses, optimisation of combustion of air supply and degasification of feed water. In order to reduce your heating input we also carry out PINCH-analyses (details).
