Measurement & Verification
Energy conservation measures and efficiency projects are tracked within Watchwire and measured and verified according to IPMVP and ASHRAE Guideline 14-2014. Designed by an AEE accredited Certified Measurement and Verification Professional (CMVP), our M&V module processes both IPMVP Option B and C analysis, depending on the data fed to the module.
Option B utilizes sub-metering and/or equipment level metering for retrofit isolation, while Option C utilizes invoice and/or whole building interval data, combined with cost data from the utility invoice. Data is regressed against weather and occupancy variables and then consumption/demand is projected to report what usage would have been in the absence of the efficiency project. Current period cost savings/avoidance are projected based on the projected usage/demand and the marginal unit cost in the current billing period. The savings (cost and energy avoidance) is the difference between what was projected and the actual metered consumption. Relevant statistics necessary for compliance with ASHRAE Guideline 14-2014, such as model CV(RMSE), are provided by the platform.
