With the enforcement of the Energy Efficiency and Conservation Act (EECA) 2024, commercial and industrial facilities in Kuala Lumpur and Selangor are now under stricter mandates to reduce energy intensity. The selection of an Air Handling Unit (AHU) is no longer just about cooling capacity; it is a matter of regulatory compliance. EKG (Malaysia) SDN BHD provides technical selection services that prioritize high-efficiency components and smart integration to ensure your HVAC system meets these new national benchmarks.
As specialized installation contractors, we align our AHU selections with MS 1525 standards to deliver a system that is both legally compliant and operationally lean.
To meet the energy reduction targets of the EECA 2024, an AHU must be selected based on its ability to modulate power and minimize thermal waste.
1. High-Efficiency Motor & Fan Technology
IE3/IE4 Premium Efficiency Motors: We prioritize AHUs equipped with IE3 or higher grade motors. These units provide significantly higher torque-to-energy ratios, reducing the base electrical load of the ventilation system.
Direct-Drive Plug Fans: By selecting direct-drive fans over belt-driven ones, we eliminate the 2% to 5% energy loss caused by belt friction and slippage. This technical choice is a cornerstone for meeting the energy intensity levels required by the Act.
2. Modulation via Variable Frequency Drives (VFDs)
Demand-Controlled Ventilation (DCV): An EECA-compliant AHU must not run at 100% capacity 24/7. EKG integrates VFDs that respond to CO2 or temperature sensors. By ramping down the fan speed during off-peak hours, energy consumption follows a cubic law—small reductions in speed lead to massive reductions in power usage.
Compliance also depends on the physical integrity of the AHU casing to ensure that produced cooling is not lost before reaching the target zone.
L1 Leakage Class Casings:
We select units with certified L1 leakage ratings (according to EN 1886). This ensures that virtually zero treated air escapes through panel joints, a critical factor in maintaining the Specific Fan Power (SFP) limits required under modern energy audits.
Thermal Break Construction:
For the humid Malaysian climate, we specify units with reinforced thermal break profiles. This prevents "thermal bridging," ensuring that the cold internal air does not cool the external skin, thereby preventing condensation and energy migration.
EKG (Malaysia) SDN BHD ensures your compliant AHU selection translates into actual TNB savings:
Total 3D BIM Coordination:
We model the selected unit and its ductwork in 3D to ensure a "clash-free" installation. Optimized duct routing with fewer sharp bends reduces the External Static Pressure (ESP) the fan must overcome, further lowering electricity consumption.
Real-Time Energy Monitoring:
Our selections often include smart meters and sensors that integrate with Building Management Systems (BMS). This allows facility managers to track real-time energy usage, simplifying the reporting requirements mandated by the EECA 2024.
High-Efficiency Heat Exchange:
We select coils with optimized fin-to-pipe ratios to maximize heat transfer. This allows the chilled water temperature to be set higher while still achieving the desired indoor climate, reducing the load on the central chiller plant.
| Feature | Standard AHU (Legacy) | EECA 2024 Compliant (EKG) |
| Motor Grade | IE1 or IE2 (Standard) | IE3 / IE4 Premium Efficiency |
| Fan System | Belt-Driven | Direct-Drive Plug Fan / EC Motor |
| Control Logic | Constant Speed (On/Off) | VFD Integrated / Demand-Controlled |
| Casing Integrity | High Air Leakage | L1 Leakage Class / Thermal Break |
| Energy Impact | High Operational Cost | Lower Monthly TNB Bills |
| Regulatory Status | Non-Compliant / High Risk | Fully Compliant with EECA 2024 |
Technical Integrity: We don't just supply equipment; we perform a full system audit to ensure the selected AHU matches your building's specific energy profile.
Turnkey Safety Compliance: All units utilize BOMBA-compliant, fire-retardant (Class 0 / B1) materials, ensuring that energy efficiency does not compromise fire safety.
Regional Compliance Experts: Based in KL, we are well-versed in the local enforcement of the EECA 2024 and provide technical proposals that protect your business from non-compliance penalties.
