C3 - Measurement and Verification Plan
Last updated:
Executive Summary
This document outlines the measurement and verification (M\&V) methodology implemented to quantify energy savings resulting from lighting system upgrades at Berry Global’s facility. The plan encompasses baseline establishment, metering infrastructure, data collection protocols, and savings calculation methodologies.
Evidence of Asset
The following documentation is maintained to support verification:
- Utility bills to corroborate baseline consumption
- Post-implementation photographic documentation
- Metering system installation documentation
- Executed Site Service Agreement
- Circuit inventory and mapping documentation
- Hourly consumption data records
Methodology Selection
We will be using the Technical Specification: Sample-Measured Reporting (Modeled Baseline, Estimated Measured Wattage which uses measured lighting consumption from a large sample of the installed fixtures, as well as a model of the pre-intervention wattage and EFLH to calculate the hourly carbon impact of the intervention.
Data Requirements
Incorporated Data Requirements
The following are defined in the Technical Specification: Common Decarbonization methodology:
- Definitions
- Electricity Carbon Intensity Calculations
- Shared Data Intake Requirements
- Consequential Carbon Accounting Rules
- EAC Definition and Rules
- Generated Versus Avoided Emissions
The following is a static description of the required and optional fields for a given Asset. An updated CSV template with the correct column names is available here and a time series description is available here. The lighting inventory must be uploaded as a document with the columns aligning with the Intervention Inventory Data description below.
Attributional Data
The following data is required in addition to what is listed in Technical Specification: Common Decarbonization methodology.
| Field | Description | Default if not provided | Required? | Use |
|---|---|---|---|---|
| Commenced Operation Date | Date the intervention was completed | Y | ||
| building_type | Classification of building according to NREL ComStock categories | |||
| Source For Pre Eflh Estimation | Source of pre-wattage EFLH estimation | Y | ||
| Measurement Sampling Method | One of: [ partial_coverage_unlabeled_sampling, partial_coverage_labeled_sampling, full_coverage_sampling] | Y | ||
| Static Wattage Analysis Summary First Dt | Datetime of start of static wattage analysis (if applicable) | |||
| Static Wattage Analysis Summary Last Dt | Datetime of end of static wattage analysis (if applicable) | |||
| Static Wattage Analysis Summary Max Power (kW) | Maximum power measured during static wattage analysis | |||
| Static Wattage Analysis Summary Number of Panels Measured | Number of panels measured during static wattage analysis | |||
| Building Annual Consumption (kWh) | Total annual consumption of the building | Y |
Intervention Inventory Data
The inventory of the full scope of the intervention should be provided as a CSV that has one row per fixture location installed with the following columns:
| Field | Description | Default if not provided | Required? |
|---|---|---|---|
| Pre-Intervention Power Per Fixture (W) | Total wattage of each pre-retrofit fixture | ||
| Post-Intervention Power Per Fixture (W) | Total wattage of each post-retrofit fixture | Y | |
| Pre-Intervention Fixture Description | A description of each pre-retrofit lighting fixture | Y | |
| Post-Intervention Fixture Description | A description of each post-retrofit lighting fixture | Y | |
| Pre-Intervention Fixture Quantity | Number of pre-retrofit light bulbs with the given wattage and description that were installed | 1 | Y |
| Post-Intervention Fixture Quantity | Number of post-retrofit light bulbs with the given wattage and description that were installed | 1 | Y |
| Pre-Intervention EFLH Estimate | An estimate of the Effective Full-Load Hours of the pre-intervention lighting fixtures. | Provided if pre-intervention occupancy schedules or measured data is not available. This is assumed to come from a modeling software. | |
| is_measured | Whether this fixture is part of the measurement ( for when only a sampling of the full intervention is being measured). | If 100% of fixtures are measured, defaults to Yes. Otherwise, defaults to Unknown (which requires an alternative means of estimating the measured wattage). | |
| pre_intervention_has_controls | A boolean of whether the fixture had controls before it was replaced. Useful to better estimate the pre-intervention loadshape. | ||
| post_intervention_has_controls | A boolean of whether the fixture had controls after it was replaced. Useful to better estimate the post-intervention loadshape. |
- Pre/Post Inventory: A line-item list of all installed lighting fixtures that includes:
- Total wattage of each pre-retrofit fixture
- Total wattage of each post-retrofit fixture
- A description of each pre-retrofit lighting fixture
- A description of each post-retrofit lighting fixture (perhaps even require model numbers?)
- Preferred:
- If not all fixtures are being measured, a label of which fixtures are being measured.
- A boolean of if the pre-retrofit fixture has controls
- A boolean of if the post-retrofit fixture has controls
- Pre-Retrofit Occupancy Schedules
- If available, measured hourly baseline period data (of at least 1 month)
- Otherwise, an estimated annual EFLH for each line-item in the Pre/Post Inventory list. This estimate should be sourced from …
- Some general information about the pre-retrofit occupancy that can be used to apply the annual EFLH over an 8760 timeseries loadshape
Timeseries Data
The timeseries data should be provided with the following columns:
| Field | Description | Required |
|---|---|---|
| start_datetime | The datetime representing the start of the hourly meter read | Y |
| energy_kwh | The energy consumption that took place during the hour associated with this meter read | Y |
Verification Protocols
Data Validation
Ongoing verification procedures include:
- Confirmation of data completeness
- Assessment of burn hour calculations
- Validation of circuit identification and mapping
- Review of savings calculations
Reasonableness Assessment
Multiple verification metrics ensure result validity:
- Total savings represent <10% of facility consumption.
- Post-implementation operating hours maintain logical relationship to baseline hours
- Connected load measurements align with documented system specifications
This M\&V plan provides a robust framework for quantifying and verifying energy savings while maintaining conservative calculation approaches and comprehensive documentation standards.
