The Registered Energy Manager (REM) AHU Audit (EECA 2024 Compliance)

In the 2026 Malaysian regulatory landscape, a Registered Energy Manager (REM) AHU Audit is a high-stakes statutory requirement. Under the Energy Efficiency and Conservation Act (EECA) 2024, buildings exceeding the energy consumption threshold (21,600 GJ/year) must undergo periodic audits led by a Suruhanjaya Tenaga (ST) certified REM.

Because HVAC systems typically represent over 50% of a tropical building's load, the AHU Box is the primary "forensic site" for these audits. At EKG (Malaysia) SDN BHD, we provide the technical T&C (Testing & Commissioning) data and structural retrofits necessary for your AHUs to pass the REM's scrutiny and secure your building's Energy Intensity Label.

1. The REM’s Audit Focus: Mandatory Benchmarks

A 2026 REM audit is not a visual inspection; it is a data-driven verification of the building's Building Energy Intensity (BEI). For AHUs, the REM looks for three critical engineering metrics:

• Specific Fan Power (SFP) Verification:

  The REM must verify that the AHUs are operating within the statutory limit of 1.6 kW/m³/s for existing units (or 1.1 kW/m³/s for new/retrofitted ones). Units using legacy belt-driven fans often fail this benchmark.

• Enthalpy Transfer & Dehumidification:

  The REM analyzes the enthalpy change ($\Delta h$) across the cooling coil. Inefficient units suffer from "The Sponge Effect"—saturated insulation that acts as a thermal bridge, forcing the chillers to waste energy to overcome casing heat gain.

• Airtightness & Static Pressure:

  The audit measures air leakage. Under MS 1525:2024, AHUs should ideally meet ATC 6 (Class L1) standards to ensure that no conditioned air is wasted in the plant room.

2. The EKG "Audit-Ready" Retrofit Protocol

We help facility managers prepare for an REM audit by modernizing the AHU infrastructure to exceed statutory requirements.

Audit Category	EKG Modernization Action	Compliance Result
Electrical Load	Replace centrifugal blowers with IE5 EC Fan Walls.	SFP typically drops to 0.6 – 0.9 kW/m³/s.
Thermal Barrier	Install TB2 Thermal Breaks & Fiber-Free Insulation.	Eliminates "Casing Sweat" and preserves R-value.
IAQ & Health	Silver-Ion (Ag+) liners & 1:50 Axial Sloping.	Microbial counts stay below 1000 CFU/m³ (DOSH 2026).
Control Logic	Integrate $CO_2$ sensors for Demand Controlled Ventilation.	Slashes energy waste during low-occupancy periods.

3. Documentation: The REM’s Evidence File

An REM cannot certify a building without a formal "Proof of Performance." EKG provides a comprehensive T&C Dossier for every unit we modernize, which includes:

1. SFP Traverse Report: A volumetric airflow and power consumption analysis.

2. Psychrometric Verification: Mapping of the cooling process to prove design enthalpy targets.

3. Acoustic & Vibration Profile: Ensuring the upgrade meets NC 35 standards.

4. Material Certifications: Proof that all insulation and sealants are Class 0 (BS 476) for BOMBA 2026 fire safety.

4. Financial Incentives: GITA & Tax Offsets

Partnering with EKG for your REM audit preparation unlocks significant financial benefits:

• 100% GITA: Our AHU energy retrofits are recognized high-tech "Green" interventions, qualifying for the Green Investment Tax Allowance (GITA).

• Penalty Avoidance: Under the EECA 2024, non-compliance with energy targets can result in fines ranging from RM20,000 to RM100,000.

• Star Rating Enhancement: Our upgrades are the fastest way to improve your building's mandatory Energy Intensity Star Rating.
