The Role of Real Time Data in Monitoring and Verification

Abstract

Monitoring and verification (M&V) performance can be greatly enhanced with the use of granular, detailed, real time energy monitoring. M&V, an important tool in energy savings performance contracts (ESPCs), is the process of measuring energy consumed before and after an energy efficiency upgrade, with the purpose of quantifying the actual energy saved. It is of utmost importance that data from M&V be accurate, and defendable. The growth and increased accessibility of real time energy monitoring (RTEM) has a significant role to play in enhancing M&V strategies. A comprehensive RTEM platform involves installing sensors at the end-use of specific equipment, whether at individual breakers in an electrical panel or at a motor control center breaker and recording consumption in real time. These data are then used to develop metrics to display and quantify the real effects of comprehensive energy upgrades. Utilizing RTEM to verify energy savings can be the most defendable, accurate M&V tool for energy service providers.
