What Are Energy Performance Indicators?

Let’s explain A Guide to Selecting and Monitoring Your Energy Performance Indicators in simple terms.

Energy Performance Indicators (EPIs or EnPIs) are numbers you use to measure how well you are using energy. www1.eere.energy.gov+24CPL+2
They let you compare now vs then, or one part of your facility vs another. Like saying: “We used X kWh per unit produced last year, now we use Y kWh.”
They help you see if things are getting better (or worse).
They also help you report to others: management, regulators, customers.

Why They Matter

Without them you’re guessing.
With the right ones, you set clear goals and you know when you’ve succeeded.
They support systems like ISO 50001 which require measurement of energy performance. ento.ai+1
They help you identify issues: sudden spike in usage, inefficient machines, changed production mix.

How to Select the Right Indicators

Here’s A Guide to Selecting and Monitoring Your Energy Performance Indicators broken into steps to pick the right ones.

Step 1: Understand Your Energy Use Context

What machines, systems, or processes use the most energy?
What’s your output or production? What drives the energy use?
What external factors matter (e.g., weather, occupancy, shift hours)?
Define the boundary of what you’re measuring (whole facility, one line, one machine).

Step 2: Define What You Want to Measure

Absolute consumption (e.g., total kWh per month).
Energy intensity (e.g., kWh per unit output, or per m²). www1.eere.energy.gov+1
Cost metrics (e.g., RM per kWh, or energy cost per unit product).
Emissions (e.g., tonnes CO₂ per year) where relevant.
Efficiency improvements (e.g., % reduction year on year).

Step 3: Choose Indicators That Are Relevant & Reliable

Relevance: Indicator must reflect the major drivers of energy use in your facility.
Reliability: Data must be available, accurate, consistent.
Simplicity: It should be understandable to people who must act on it.
Comparability: You should be able to track over time or compare across units or processes.

Step 4: Set Baselines and Targets

Establish a baseline period (for example last 12 months) so you know the “starting point”. www1.eere.energy.gov+1
Set targets: for example “reduce kWh per unit by 10% in 12 months”.
Make sure everyone understands what the indicator means, how it’s calculated, and what the target is.

Step 5: Document the Methodology

How do you calculate the indicator?
What data sources are used (meters, utility bills, production logs)?
Which variables or factors are included or excluded? (e.g., weather corrections, occupancy changes).
Review the method regularly to ensure it remains valid. www1.eere.energy.gov+1

How to Monitor and Use Your Indicators

Once you’ve selected your indicators, you need to monitor them and use the data to drive improvement. Here’s how to incorporate A Guide to Selecting and Monitoring Your Energy Performance Indicators into ongoing operations.

Data Collection

Ensure data collection systems capture the right information. Meters, sensors, log-books.
Establish frequency: weekly, monthly, quarterly.
Ensure data quality: calibration, validation, consistent time periods.
Recognize external variables: production volume, weather, operational hours.

Reporting & Visualisation

Use dashboards or charts: trend lines, bars, before/after comparisons.
Highlight key indicators: e.g., energy intensity trending down or up.
Make reports understandable: indicate whether you’re meeting targets or not.

Analyse and Act

If an indicator shows improvement: understand what actions caused it. Promote them.
If performance worsens: investigate. Possible causes: equipment fault, process change, incorrect data.
Use indicators to guide decisions: invest in new technology, change operating hours, staff training.

Review and Revise

Every year (or more frequently) review whether indicators are still valid.
Adjust targets or indicators if business operations change.
Report findings to management and discuss corrective actions.

Common Indicators You Could Use

Here are examples of indicators to consider when following A Guide to Selecting and Monitoring Your Energy Performance Indicators.

Total energy consumption (kWh) per month or year.
Energy intensity: kWh per unit of production, or kWh per m² of floor area.
Energy cost per unit output (RM or USD per unit).
Percentage of renewable energy used.
CO₂ emissions per unit output or per kWh.
Ratio of energy use to production hours or occupancy.
Energy use non-production hours (indicator for waste or standby power).
Baseline deviation: difference between current use and baseline.

Challenges and How to Overcome Them

Selecting and monitoring indicators comes with hurdles. Here’s how to address common issues when applying A Guide to Selecting and Monitoring Your Energy Performance Indicators.

Challenge: Data Gaps or Poor Quality

Fix by implementing proper metering, sensors, logging systems.
Ensure staff understand importance of correct data entry.

Challenge: Too Many Indicators

Avoid overload: focus on 3-5 key indicators rather than dozens.
Ensure they align with business goals and energy drivers.

Challenge: Operational Changes Alter Context

Example: Production increases much faster, or changes product mix.
Solution: Adjust baseline or normalise data (e.g., per unit output).
Document changes and adjust targets.

Challenge: Lack of Management Buy-in

Show the value: link indicators to cost savings, environmental goals, risk reduction.
Use reports and visuals that are easy for non-technical stakeholders.

Challenge: Indicators not Leading to Action

Indicators must trigger action: define “What next” when target missed.
Assign responsibilities: Who monitors, who investigates, who acts.

Aligning Indicators with Standards and Best Practice

It’s wise to align your selection and monitoring of indicators with recognised standards. This supports the legitimacy and consistency of A Guide to Selecting and Monitoring Your Energy Performance Indicators.

ISO 50001 provides guidance for selecting EnPIs and establishing baselines. www1.eere.energy.gov+1
The Malaysian guidelines for EnMS under the Energy Efficiency and Conservation Act 2024 include definitions like “Energy Efficiency Indicator (EEI)”. Suruhanjaya Tenaga
Organisations like ENERGY STAR provide sector-specific EPIs and benchmarking tools. ENERGY STAR

By aligning with these, you ensure your indicators are meaningful, credible, and comparable.

Case Example (Simplified)

Here is a simplified fictional example to illustrate A Guide to Selecting and Monitoring Your Energy Performance Indicators in practice.

Company: A manufacturing plant.
Step 1 – Context: Key energy use: motors, HVAC, lighting. Production output in units per month.
Step 2 – Indicators selected:

Energy intensity: kWh per unit produced.
Energy consumption during non-production hours: kWh per hour.
Energy cost per unit output: RM per unit.
Step 3 – Baseline & target:
Baseline: Last 12 months: 100 kWh/unit.
Target: 10% reduction → 90 kWh/unit in 12 months.
Step 4 – Data & Monitoring:
Monthly meter reading + production log.
Chart shows trend. At month six: 95 kWh/unit.
Step 5 – Action:
Investigate: Lighting upgrades, motor replacements, adjust production schedule.
Step 6 – Review:
After 12 months: achieved 88 kWh/unit → target met.
New target set: 80 kWh/unit next year.
Outcome: Improved energy performance, lower cost, better competitiveness.

Integrating into Your Culture & Systems

To really make A Guide to Selecting and Monitoring Your Energy Performance Indicators work long term, you need culture and systems.

Embed the indicators into regular meetings (monthly review, quarterly board update).
Assign a responsible person or team to monitor and report.
Use software or spreadsheets to track and visualise data.
Train staff: what the indicators mean, how their work affects them.
Link indicators to rewards or recognition: e.g., “lowest kWh/unit achieved this quarter”.
Adjust business processes: operations scheduling, maintenance, procurement decisions based on indicator data.

How to Report and Communicate Your Indicators

Good communication ensures your indicators drive impact.

Use clear visuals: simple dashboards, trend charts, traffic-light colours.
Tell the story: “We reduced energy intensity by 12% by upgrading motors and shifting schedules.”
Highlight benefits: cost savings, lower emissions, improved equipment reliability.
Tailor audience:
- For management: high-level indicator summary, targets met.
