With the Energy Efficiency and Conservation Act (EECA) 2024 officially in effect as of January 1, 2025, the standards outlined in MS 1525 have shifted from voluntary guidelines to a mandatory technical framework for designated buildings in Malaysia. For Air Handling Units (AHUs), this means that energy-saving features are no longer just "options" but legal requirements to maintain a building's 2-star minimum energy rating.

At EKG (Malaysia) SDN BHD, we engineer our AHU systems to exceed these benchmarks, ensuring long-term compliance and operational savings.

1. Mandatory Specific Fan Power (SFP)

The MS 1525:2019 (and the subsequent 2024 enforcement) focuses heavily on the efficiency of air distribution. The core metric is Specific Fan Power (SFP), which measures how much electrical power is needed to move a specific volume of air ($kW/m^3/s$).

• Compliant Target: MS 1525 generally mandates an SFP of less than 1.6 $kW/m^3/s$.

• EKG Implementation: We achieve this by using Direct-Drive EC Fans (IE5). Unlike traditional belt-driven fans that lose 5% to 12% of energy to friction, EC fans ensure that almost 100% of the motor power is used for airflow, keeping your building well within the legal SFP limits.

2. Thermal Integrity & Energy Migration

A major focus of the latest standards is preventing the loss of cooling energy through the AHU casing itself.

• TB2 Thermal Break: To meet MS 1525 efficiency goals, modern AHUs must prevent "cold bridging." Our units feature TB2-rated thermal breaks that stop heat from the mechanical room from leaking into the air stream and prevent condensation ("sweating") in Malaysia's high humidity.

• L1 Leakage Class: Under the new Act, air leakage is treated as direct energy waste. We utilize L1-certified airtight casings to ensure that all treated air reaches the occupant, preventing "parasitic" energy loss that would otherwise inflate your Building Energy Intensity (BEI).

3. Demand-Controlled Ventilation (DCV)

The EECA 2024 requires buildings to implement an Energy Management System (EnMS). For HVAC, this is primarily achieved through Demand-Controlled Ventilation (DCV).

• Sensor Integration: MS 1525 encourages using CO2 and occupancy sensors to modulate airflow.

• Smart Modulation: Our AHUs use Variable Frequency Drives (VFDs) to ramp down motor speed when occupancy is low. Due to the physics of fans, reducing the speed by just 20% can cut power consumption by nearly 50%, directly improving your BEI star rating.
