Description |
Typical Applications |
A Partially Measured Retrofit Isolation |
Savings are determined by partial field measurements of the energy use of the system(s) to which an ECM was applied. Some, but not all, parameters may be stipulated. |
Lighting retrofit where pre- and post-retrofit fixture Wattages are measured. Operating hours of the lights are typically agreed upon. |
B Retrofit Isolation |
Savings are determined by field measurement of the energy use of the systems to which the ECM was applied. |
Variable speed drive on a pump. Electricity use is measured by a kWh meter installed on the electrical supply to the pump motor. |
C Whole Facility (Utility Bills) |
Savings are determined by measuring energy use at the utility meter level. Bills may be corrected for weather. |
Several ECMs affecting many systems in a building. Utility Bills are used. |
D Calibrated |
Savings are determined using building simulation. This option is rarely used, and is used primarily when there is no pre-retrofit utility data available. |
Multifaceted energy management program affecting many systems in a building but where no base-year data are available. |
