Development of a New Extended Motor Product Label for Inclusion in Energy Efficiency Programs

摘要

Energy efficiency program administrators have for many years been aware of thernsignificant energy savings possible with optimization of motor-driven systems. However,rnrealization of these opportunities has historically been limited to larger systems because of therncost of the resources required to measure and verify the savings. A number of recentrndevelopments may change this. First, the development of specifications and labeling for motordrivenrnsubsystems or packages offers the prospect of capturing some of the system effects. Lowcostrnsensors and control systems now also enable these packages to achieve some degree of selfoptimization.rnManufacturers of electric motors, pumps, fans, and compressors are developing voluntaryrnlabels for motor-driven systems (e.g., a fan, pump, or compressor and the motor and associatedrncontrols) to reflect the equipment’s relative efficiency as it is installed in a motor-systemrnapplication. The development of a driven component or “extended product” label combined withrnimplementation data could be the basis for prescriptive rebate programs with deemed savingsrnvalues. Such programs would accelerate the adoption of more efficient motor-driven systems.rnThis paper explains the activities of a collaborative effort, the Extended Motor ProductrnLabel Initiative, to develop comparative metrics and labels for three categories of extendedrnproducts. Also discussed are the ways its three working groups are ensuring the compatibility ofrnthese new extended-product labels with energy efficiency program measurement and verificationrnneeds. Finally, the paper describes the plan for development and public introduction of three orrnmore efficiency program model proposals.
