Continuing from our previous blog, this discussion looks at four options on measurement and verification (M&V) plans: Option A: Retrofit Isolation Option A applies to a single Energy Conservation Measure (ECM) with the key parameter measured. Savings are determined by field measurement of the key performance parameter(s), which define the energy use of the ECM. Non-key parameters are estimated. For example, an energy-efficient pump/motor upgrade may estimate annual pump operating hours (non-key parameter) and measure the electrical motor power (key parameter). Option B: Retrofit Isolation Option B applies to a single ECM with all parameters measured. Savings are determined by […]
