GlacierGrid Energy calculates potential cost savings using the International Performance Measurement and Verification Protocol (IPMVP) Option C. IPMVP was developed by the Efficiency Valuation Organization (EVO) and the US Department of Energy as a framework designed to measure and verify energy performance and savings from energy-efficiency projects.
This method comprehensively analyzes 12 months of past energy data, diverse weather conditions, and billing cycle lengths. We use regression analysis to understand and project energy savings, factoring in various weather-related influences and operational data.
Using IPMVP in energy management offers several benefits:
Accurate measurement:
It provides precise measurement and verification of energy savings, making it a reliable and trustworthy basis for claims related to energy efficiency.
Credibility and trust:
Since IPMVP is an internationally recognized standard, businesses that adhere to this boost the credibility of energy conservation initiatives.
Informed decision-making:
Accurate data from IPMVP enables better decision-making and benchmarking across facilities.
Continuous improvement:
It allows for ongoing monitoring and optimization, leading to the identification and implementation of further energy-saving measures.
The IPMVP offers several options for verifying savings—each suited to different types of projects and available data. These options are categorized as A, B, C, and D, each providing a different methodology for measurement and verification (M&V).
Option A: Partially measured retrofit isolation
This option measures energy savings through key component measurement and uses estimates for the rest of the system. It's typically used when direct energy savings measurements are possible for significant project components but only for part of the system.
Option B: Retrofit isolation
Option B measures energy savings by isolating and directly measuring the energy use of systems or subsystems. It suits projects with localized energy savings to specific equipment or systems, allowing for direct and precise measurement.
Option C: Whole facility
Option C assesses energy savings at the whole facility level by comparing total energy use before and after implementing energy efficiency measures. This approach is valuable for projects with multiple energy conservation measures affecting various systems, making it difficult to isolate individual savings. It relies on utility bills or whole-building metering to assess changes in energy consumption.
Option D: Calibrated simulation
This option estimates energy savings using computer simulations calibrated with actual facility energy use data. It's often used when physical measurements are impractical or the project involves complex interactions between various building systems.
GlacierGrid Energy opts for IPMVP Option C for several reasons:
In a nutshell, IPMVP Option C aligns with GlacierGrid Energy's objectives by providing a robust, credible, and scalable methodology for measuring and verifying the energy savings achieved through their comprehensive energy efficiency solutions. This choice underscores GlacierGrid Energy's commitment to delivering transparent and reliable energy savings to its clients.
The calculation uses a variety of data, including:
Yes, GlacierGrid Energy makes routine and non-routine adjustments during calculation. These adjustments consider operational changes, such as variations in occupancy or production shifts, and changes in weather patterns that might influence energy usage.
GlacierGrid Energy ensures accuracy through continuous measurement and verification of energy use and pre- and post-implementation of energy efficiency measures. Using IPMVP Option C and rigorous data analysis and adjustments, GlacierGrid provides reliable and verifiable energy savings reports for our clients.
