The energy audit: find the waste, prove the savings.
EECA 2024 makes a structured energy audit compulsory for large energy users — your first within twelve months, then on a repeating cycle. Done well, it's not a box-tick: it's the map of every ringgit your site is leaking. Here's what it covers, who runs it, and how KERO has the evidence ready before the auditor arrives.
An energy audit under EECA 2024 is a structured assessment of where a site's energy goes and where it is wasted — broken down by system, process and time — with practical recommendations to cut consumption. It is conducted by a Registered Energy Auditor and is one of the core duties of a registered energy consumer.
Under the Energy Efficiency and Conservation Regulations 2024 (EECR 2024), the first audit must be completed within 12 months, and re-audits then repeat periodically — about every five years — while your energy management system runs continuously in between.
What an energy audit actually looks at.
A credible audit goes well past the utility bill. It traces energy from the meter to the machine, and quantifies what's being wasted at each step.
Consumption, broken down
Total energy use across every source, then split by system — HVAC, compressed air, process loads, lighting — so the big consumers are obvious, not assumed.
Waste, quantified
Idle running, off-peak loads that shouldn't be on, drifting equipment, poor power factor — the recurring losses that never show up on a monthly bill.
Recommendations, prioritised
Concrete measures ranked by saving and payback, so the audit ends in an action list — not a PDF that gets filed and forgotten.
A Registered Energy Auditor conducts the audit.
EECA 2024 keeps the audit independent: it's carried out by a Registered Energy Auditor registered with Suruhanjaya Tenaga, distinct from the Registered Energy Manager who runs your day-to-day energy management.
When audits happen — and why it never really stops.
First energy audit
Completed within twelve months as a registered energy consumer, establishing your baseline and first action list.
The EnMS keeps measuring
Between audits the energy management system runs — tracking performance against the baseline so improvements stick. What an EnMS requires →
Re-audit
The audit repeats on a periodic cycle, re-baselining the site and checking that earlier measures held — and finding the next round of savings.
Exact audit scope, methodology and frequency are set by Suruhanjaya Tenaga under EECR 2024. Confirm the current requirements for your site with ST or your Registered Energy Auditor.
The audit evidence, gathered before anyone asks.
The reason audits are painful is that the data isn't there when you need it. KERO flips that: by the time the auditor arrives, the measurement is already done.
| What the audit needs | The usual way | With KERO |
|---|---|---|
| Consumption by system | Manual readings, clamp meters, estimates | Continuous sub-metering, already split by system and time |
| A baseline | Twelve months of bills, pieced together | A live baseline built from real data from day one |
| Waste, identified | A few days of spot-checks during the audit | Anomalies and idle loads flagged all year round |
| An audit trail | Spreadsheets reassembled each cycle | A complete, timestamped record, exportable on demand |
