A more efficient solution is to use a drive to adapt the speed of an electric motor connected to a fan or pump to obtain the required flow. This can reduce electricity consumption by up to 70 percent.
Additionally, new legislation setting minimum efficiency performance standards (MEPS) for electric motors is being introduced in many countries. These standards cover a wide range of low voltage electric motors in the EU, USA and Australia, for example.
The aim of the MEPS is to legislate efficient electric energy use by devices, thereby lowering those devices’ carbon footprint. This concept is also included in an energy appraisal, where CO2 emissions are part of the analysis. And just like the MEPS, CO2 emissions must be considered from a local perspective.
Local conditions also influence how the energy appraisals are organized. In a large industrial country like Germany, for example, the energy appraisal can be executed by one of ABB’s many partners. In countries with a smaller industrial base, such as Malaysia and Singapore, ABB will use its own appraisal teams.
