Measurement & Verification

Basics of Energy Monitoring & Verification

The basic principle of Monitoring & Verification is to compare the monitored energy consumption and demand after implementation with that of the measurements before implementation. The process is meant to quantify and assess savings while yielding numerous other benefits. Beside energy cost savings, other benefits include better preventative maintenance, improved budgeting, improved product quality, waste avoidance, etc.


What is Energy Monitoring?

Energy Monitoring is the regular collection of information on energy use. Its purpose is to establish a basis of management control, and this baseline in turn will be utilized to determine when and why energy consumption is deviating off-pattern. Target setting will then be utilized, wherein objective goals are established in relation to the determination of energy consumption levels. Information on the energy use levels of the following can be determined by monitoring plant level performance, plant department performance, system performance, and equipment level performance. To be brief, the establishment of a baseline and a pattern is the singular purpose of monitoring.


What is Energy Savings Verification?

Energy Savings Verification is the process by which energy consumption is quantified before and after the implementation of an energy conservation measure (ECM). The purpose is to verify and determine the level of savings achieved by building retrofits. Baseline adjustments may need to be made, and they are typically the most difficult to quantify in the process of energy savings verification.


How Do You Monitor and Verify Energy Usage?

A standard protocol has been created for Monitoring & Verification—the International Performance Monitoring and Verification Protocol (IPMVP). The IPMVP establishes four options for the verification of energy savings:

i.   Retrofit Isolation: All of the parameters of an Energy Conservation Measure (ECM) are measured or monitored.

ii.  Partially Measure Retrofit Isolation: Key parameters of an ECM are measured while others are assumed.

iii.  Whole Building: Utility meters are used, and individual ECMs are not metered. This option is generally used when energy savings are substantial.

iv.  Calibrated Simulation: When there is no data available for the baseline, a simulation model is made to estimate the amount of energy used by a facility.


What Does Energy Performance Management Entail?

Associated Renewable’s energy performance management solutions help ensure your building is operating at its optimal level and lowest cost.  Energy Performance Management an instrumented approach for gathering data from sensors in energy-consuming devices and communicating that data to interconnected resources or to back-end business processes or applications. This, in turn, enables intelligent decisions and actions that can lower energy use and help reduce maintenance costs and equipment downtime. The immediate goal is to increase operational efficiency, extend equipment lifetime and reduce overall costs. Associated Renewable looks at buildings from a holistic approach in order to maximize savings and minimize costs. We can help create a roadmap to get your “whole-building” running to its highest performance.


Our Process

After evaluating, purchasing and installing new equipment for your building’s retrofit, Associated Renewable will benchmark its energy use so we have a baseline to compare energy performance in the year after implementation. Measurement of results will include gathering and tracking data through our energy management system software.  We will then review your building’s energy use and cost each year. Our energy engineers will furnish a report that will analyze performance targets (e.g. savings) achieved and highlight areas that deserve attention.  This will help monitor energy performance of your building post-retrofit, and also generate awareness about future energy projects that may need your attention.  Good energy management is good business and Associated Renewable can help you succeed. Contact our Energy Solutions team to put together a comprehensive M&V plan for your buildings.
