Energy Conservation Measure (ECM)
Energy Conservation Measures (ECMs) are actions or upgrades that reduce energy use in a building. They can be simple changes like LED lighting and thermostat schedules or larger projects like high-efficiency HVAC systems, insulation, and controls. ECMs cut utility costs, improve comfort, and lower environmental impact. In this context, ECM refers to conservation measures, not electronically commutated motors.
