EECA 2024 Compliant AHU Design

With the Energy Efficiency and Conservation Act (EECA) 2024 officially in effect as of January 1, 2025, commercial and industrial buildings in Kuala Lumpur and Selangor are now under a mandatory legal framework to reduce energy intensity. In this new regulatory environment, Air Handling Unit (AHU) design is no longer just about cooling—it is a critical component of statutory compliance.

 

EKG (Malaysia) SDN BHD specializes in engineering AHU systems that meet the stringent requirements of the EECA 2024, ensuring your facility achieves the necessary Building Energy Intensity (BEI) ratings while avoiding the heavy penalties associated with non-compliance.

Understanding AHU Compliance in KL

Under the EECA 2024, office buildings with a Gross Floor Area (GFA) of 8,000 $m^2$ or more, and industrial users consuming over 21,600 GJ annually, must meet specific performance benchmarks.

 

1. Mandatory BEI Labeling & Star Ratings

• Minimum 2-Star Requirement: Every designated building must obtain and display a Building Energy Intensity (BEI) label from the Energy Commission (Suruhanjaya Tenaga). To remain compliant, a building must maintain a minimum 2 out of 5 stars.

   

• AHU Impact on BEI: Since HVAC systems typically account for 50% to 60% of a commercial building’s energy use, an inefficient AHU design is the most common reason for a failing star rating. EKG’s compliant designs focus on lowering the $kWh/m^2$ metric to secure a 3-star rating or higher.

2. Specific Fan Power (SFP) Limits

• MS 1525 Alignment: The EECA 2024 leverages the technical standards found in MS 1525. Compliant AHU design requires minimizing the energy used to move air. We prioritize high-efficiency EC Plug Fans that eliminate the 5% to 7% energy loss seen in traditional belt-driven systems, ensuring your fan power stays within the legal limits.

Technical Design Pillars for EECA 2024

EKG (Malaysia) SDN BHD integrates four key technical strategies into every EECA-compliant AHU project to ensure long-term energy savings and legal peace of mind.

1. Demand-Controlled Ventilation (DCV)

• Compliant units cannot run at constant speeds. We integrate Variable Frequency Drives (VFDs) paired with CO2 and occupancy sensors. This allows the AHU to ramp down during low-occupancy periods, a primary requirement for the "Energy Management System" (EnMS) mandated by the Act.

2. L1 Leakage Class Casings

• Energy efficiency is lost through air leakage. We specify Double-Skin AHUs with certified L1 leakage ratings. This ensures that 100% of the energy used to cool the air actually reaches the occupied space, directly supporting your building’s energy intensity targets.

3. Premium IE3/IE4 Motors

• The EECA 2024 focuses on "Energy-Using Products." We select AHUs equipped with Premium Efficiency (IE3) or Super Premium (IE4) motors, ensuring the core drive unit meets the new Minimum Energy Performance Standards (MEPS).

   

4. 3D BIM for Static Pressure Optimization

• High duct resistance forces fans to work harder. We use 3D BIM modeling to design "clash-free" and aerodynamically optimized duct layouts. By reducing the External Static Pressure (ESP), we allow the AHU to operate at its Best Efficiency Point (BEP), further lowering your BEI score.

The Cost of Non-Compliance

The Energy Commission (ST) has the authority to audit facilities and enforce penalties for failing to meet energy intensity targets or for not displaying the mandatory BEI label:

 

• Fines: Non-compliance with energy audit and reporting requirements can result in fines ranging from RM20,000 to RM100,000.

   

• Mandatory Audits: Buildings that fall below the 2-star performance level are legally required to undergo an intensive energy audit and implement a formal Energy Efficiency Improvement Plan.
