T&C: MS 1525:2024 Energy Efficiency Compliance Reports

As of 2026, MS 1525:2024 (the latest revision of the Code of Practice on Energy Efficiency and Use of Renewable Energy for Non-Residential Buildings) serves as the technical backbone for the Energy Efficiency and Conservation Act (EECA) 2024. In Malaysia, specifically for projects in Kuala Lumpur and Selangor, Testing & Commissioning (T&C) reports are now a statutory bridge required by the Suruhanjaya Tenaga (ST) to prove that an AHU or AC system meets mandatory performance benchmarks.

At EKG (Malaysia) SDN BHD, we specialize in providing "Audit-Ready" T&C reports that satisfy both MS 1525 technical standards and EECA legal mandates.

1. The MS 1525:2024 Statutory Framework

Under the 2024/2026 standards, T&C reports must provide empirical evidence of three primary energy metrics:

• Specific Fan Power (SFP): AHUs must not exceed the statutory limit of 1.6 kW/m³/s. Our reports include simultaneous measurements of motor kW and volumetric airflow ($m^3/s$) to verify compliance.

• Building Energy Intensity (BEI): For office buildings $\ge$ 8,000 $m^2$, the maximum allowable BEI is capped at 250 kWh/m²/year. The T&C report proves the HVAC system is optimized to help achieve this target.

   

• Static Pressure Reset: Reports must verify that VFD-driven AHUs utilize control logic to reduce static pressure during partial loads, a mandatory requirement for 2026 energy efficiency certification.

2. Core Modules of an MS 1525 T&C Report

Our mechanical specialists utilize NATA-traceable, calibrated instruments to populate your compliance documentation.

Report Section	Engineering Metric	2026 Compliance Requirement
Airflow Traverse	Volumetric Flow ($m^3/h$)	Must be within ±10% of Design to prevent over-ventilation waste.
ESP Verification	Static Pressure (Pa)	Verification that duct resistance is minimized to keep SFP low.
Hydronic Balance	Delta T Verification	Achievement of a high $\Delta T$ (min $5.5^\circ\text{C}$) to optimize chiller COP.
Acoustic Signature	Sound Power Level ($L_w$)	Maintenance of NC 30-35 to ensure IEQ (Indoor Environmental Quality).

3. Integration with EECA 2024 Notices

Beginning in January 2026, the Energy Commission (ST) has started issuing official Energy Consumer Notices to organizations exceeding the consumption threshold (21,600 GJ/year).

 

1. REM Submission: Your Registered Energy Manager (REM) uses our MS 1525 T&C reports as the technical baseline for mandatory annual energy efficiency submissions.

2. EnMS Verification: We ensure the AHU performance data is accurately mapped into your Energy Management System (EnMS), as required by Section 6 of the Act.

3. GITA Documentation: Our reports provide the necessary technical proof for the 100% Green Investment Tax Allowance (GITA), certifying that your equipment meets the "High Efficiency" criteria.

4. The "Fire & Safety" Statutory Overlay

MS 1525 compliance must never compromise life safety. Our reports include a witness section for BOMBA (JBPM) 2026 requirements.

• Automatic Fire Signal AHU Shut-off: Verification that the energy-saving VFD controls yield to the fire alarm signal instantly.

• Motorized Fire Damper (MFD) Log: Confirmation that all dampers reach a 100% smoke-tight seal while the AHU is in its "Fire State."

• BOMBA Audit: These T&C logs are essential for the annual renewal of your building's Fire Certificate (FC).
