CSA Group technical committee, C402 on energy efficiency of industrial equipment, has sanctioned the publication of a new standard to benchmark the energy efficiency of commercial and industrial fan systems.

Through the benchmark energy factor (BEF) concept, this BEF standard will provide a unified and consistent method for performing measurement activities and assessment of actual operating system energy performance.

The intent of this standard is to develop uniform methods to measure and assess the overall efficiency of open and closed loop, electric driven fan systems typically used at commercial and industrial facilities. The intent is not to prescribe minimum efficiency levels of fan components or systems for manufacturers but rather provide an energy performance indicator of actual operating system efficiency.
