A Case Study: How a Malaysian Manufacturer Achieved ISO 50001 Certification
1. Background: Why Energy Management Became a Priority
In this case study, we’ll explore how ABC Manufacturing Sdn Bhd (a mid-sized Malaysian company) successfully achieved ISO 50001 certification. The company produces automotive components and operates multiple production lines that run 24/7.
For years, energy consumption was seen as a fixed cost. But as electricity tariffs rose and sustainability pressures increased, management realized they needed a strategic approach — not just ad-hoc savings projects.
They discovered that ISO 50001, the international standard for energy management systems, could provide the framework to control, measure, and continuously improve energy performance.
2. Why They Chose ISO 50001
The management team had three main reasons for pursuing ISO 50001 certification:
-
Cost Control: Energy represented nearly 30% of total operating expenses. Reducing even 5% would mean huge savings.
-
Customer Demand: Key clients in Japan and Europe began requiring suppliers to meet sustainability standards.
-
Corporate Reputation: The company wanted to be recognized as an environmentally responsible manufacturer in Malaysia.
By aligning with ISO 50001, they could achieve both operational efficiency and environmental credibility.
3. Step 1: Gaining Leadership Commitment
The journey toward certification started with top management buy-in — the most critical factor for success.
Here’s how they did it:
-
Conducted an initial energy audit to show how much money was being lost to inefficiency.
-
Presented a business case to the board linking energy savings to profit margins.
-
Appointed an Energy Management Representative (EnMR) to lead the ISO 50001 implementation team.
Once leadership committed, they allocated a small but strategic budget for data collection tools, staff training, and consultancy support.
4. Step 2: Establishing the Energy Management Team
A cross-functional Energy Management Team was formed, including:
-
Maintenance engineers
-
Production supervisors
-
Facility managers
-
A finance representative
-
An external energy consultant
Their role was to implement the ISO 50001 framework step by step, ensuring collaboration between departments that traditionally worked in silos.
5. Step 3: Conducting the Energy Review
This stage involved gathering detailed data on where and how energy was used.
Key actions taken:
-
Installed sub-meters on major equipment (compressors, chillers, and furnaces).
-
Collected three months of baseline data on electricity consumption.
-
Identified Significant Energy Uses (SEUs) — systems that consumed the most energy.
From the data, they learned that compressed air systems were the biggest energy hogs, followed by HVAC and lighting.
This insight became the foundation for their Energy Performance Indicators (EnPIs) and energy objectives.
6. Step 4: Setting Objectives and Action Plans
Using insights from the energy review, the team set SMART goals (Specific, Measurable, Achievable, Relevant, and Time-bound):
-
Reduce total energy consumption by 10% within 12 months.
-
Lower compressed air leakage losses by 20%.
-
Improve chiller system efficiency by 15%.
They then created an Energy Management Action Plan that included:
-
Regular leak inspections
-
Optimized operating schedules
-
Preventive maintenance for air compressors
-
Replacement of old fluorescent lights with LED systems
Each goal had a responsible person, timeline, and monitoring method.
7. Step 5: Building Awareness and Training Staff
One of the biggest success factors in A Case Study: How a Malaysian Manufacturer Achieved ISO 50001 Certification was employee involvement.
The company realized energy management wasn’t just a technical task — it required behavioral change.
Their approach included:
-
Conducting training sessions on energy-saving practices.
-
Creating posters and reminders near machines and switchboards.
-
Rewarding teams that achieved monthly energy-saving targets.
This culture-building approach turned awareness into measurable action.
8. Step 6: Implementing Operational Controls
To sustain improvements, they introduced operational controls, such as:
-
Automatic timers for lighting and exhaust fans.
-
Set temperature limits for air conditioning.
-
Maintenance schedules for compressor filters and motors.
-
Standard Operating Procedures (SOPs) for equipment shutdowns.
By formalizing these controls, energy management became part of daily operations — not just a one-time project.
9. Step 7: Monitoring, Measurement, and Evaluation
The company installed a simple Energy Monitoring System (EMS) to track real-time energy consumption.
They used dashboards to:
-
Compare daily energy usage to production output.
-
Identify unusual spikes in consumption.
-
Track progress toward EnPIs and energy targets.
Monthly review meetings allowed the team to discuss data trends and make quick adjustments.
By using data-driven decision-making, they reduced energy waste and improved accountability across departments.
10. Step 8: Internal Audits and Management Review
Before applying for certification, the company conducted internal audits to evaluate compliance with ISO 50001 requirements.
Key steps included:
-
Reviewing documentation and records.
-
Verifying the effectiveness of operational controls.
-
Identifying non-conformities and implementing corrective actions.
Finally, a management review meeting was held to evaluate overall performance, set new targets, and prepare for the external audit.
11. Step 9: External Certification Audit
The certification process involved two stages:
-
Stage 1 – Documentation Audit:
The auditor reviewed the company’s policies, energy review, and management system documentation. -
Stage 2 – Implementation Audit:
The auditor visited the factory floor to verify that systems and practices matched the documented procedures.
After addressing minor findings, ABC Manufacturing successfully achieved ISO 50001:2018 certification within 14 months of starting the project.
