Commercial Energy Audit

Stop guessing where the kWh goes. Our MS 1525-aligned energy audit covers electricity, HVAC, lighting, motors, compressed air, refrigeration, and process heat. Investment-grade report. Bankable savings projection. RM 4,000 – RM 25,000 fixed-fee.

Trexon Energy Commercial Energy Audit Malaysia — MS 1525 Compliant

From RM 4,000 walk-through · RM 25,000 investment-grade

What we audit

Every energy end-use is measured, not estimated. We identify the real waste, not the textbook waste.

Electricity & Maximum Demand

Baseline kWh and MD (kVA) profiling against TNB tariff blocks. We identify peak demand spikes, poor power factor penalties, and half-hourly load shape to right-size any solar + battery pairing.

HVAC & Chillers

Chiller COP benchmarking, AHU fan speed analysis, cooling tower drift loss, and thermostat setpoint audit. Typically 30–50% of a commercial building's electricity bill — the highest-return target.

Lighting

Lux-level mapping against MS 1525 recommended illuminance. We calculate kWh savings from LED retrofits, daylight zoning, and occupancy-sensor controls — with a room-by-room payback table.

Motors & Pumps

Load factor and efficiency class assessment for all motors ≥3.7 kW. VSD retrofit sizing, rewound motor efficiency loss estimates, and pump affinity-law savings projections.

Compressed Air

Leak detection (ultrasonic), operating pressure vs. equipment requirement, air receiver sizing, and compressor part-load efficiency. A 10% pressure reduction saves ~5% energy — often RM 50,000+/yr in factories.

Refrigeration & Cold Rooms

Refrigerant charge, condenser fouling, evaporator defrost cycle, and door seal integrity checks. Cold room envelope U-value assessment for food & pharma facilities.

3 audit levels — choose your depth

Each level builds on the last. Upgrade to a deeper scope at any point — we credit your earlier engagement fee.

Standards we map to

Our findings are structured so the same data supports multiple certification and incentive frameworks simultaneously.

MS 1525

Malaysian standard on energy efficiency and use of renewable energy in non-residential buildings — our primary benchmark.

MGTC LCCF

Low Carbon Cities Framework & Assessment System — relevant for facilities seeking GreenRE or MyHIJAU certification.

GreenRE

Green Real Estate rating system aligned to MGTC. Our audit evidence supports GreenRE Energy credits directly.

ISO 50001

International Energy Management System standard. Our Level 3 audit includes a gap analysis to identify what's needed for certification.

How the audit works

Four clear phases from first call to final report. No surprises.

1

Step 1Kick-Off & Data Request

We issue a data request list covering 12 months of TNB bills, equipment schedules, floor plans, and operation hours. A 1-hour kick-off call aligns scope and access logistics.

2

Step 2Site Instrumentation

Our engineers install data loggers, clamp meters, lux sensors, and compressed air leak detectors. For Level 1, this is a visual walk-through only.

3

Step 3Engineering Analysis

We model your baseline energy use, benchmark it against MS 1525 targets, rank ECMs by NPV, and size any solar + battery configuration against your actual demand profile.

4

Step 4Report Delivery & Q&A

Final report delivered in PDF and editable Excel. We present findings to your engineering and finance teams and answer questions in a 90-minute handover session.

Know exactly where your energy budget is going

Most Malaysian facilities overpay by 15–30% on their TNB bill. A Level 2 audit typically pays for itself within 3 months of implementing the top 3 ECMs.
