Low BEI Commercial Air Handling Units by EKG (Malaysia) SDN BHD

In the competitive commercial landscape of Kuala Lumpur and Selangor, the Building Energy Intensity (BEI)—measured in $kWh/m^2/year$—is the primary metric for assessing a facility's efficiency. Since HVAC systems often account for over 50% of a building's total energy consumption, the selection of Low BEI Air Handling Units is critical. EKG (Malaysia) SDN BHD specializes in engineering AHU systems that directly lower your BEI, supporting Green Building Index (GBI) certification and high-performance operations.

As specialized installation contractors, we focus on technical strategies that align with MS 1525 and ensure your facility meets the mandatory energy intensity targets of EECA 2024.

Engineering Strategies for BEI Reduction

Lowering the BEI requires a shift from "maximum cooling" to "maximum efficiency." EKG achieves this through three core engineering pillars.

1. Specific Fan Power (SFP) Optimization

• High-Efficiency EC Plug Fans: We utilize Electronically Commutated (EC) fans that eliminate transmission losses from belts and pulleys. By reducing the energy required to move a specific volume of air ($W/m^3/s$), we significantly lower the "Ventilation" component of your BEI.

• Low-Resistance Internal Geometry: EKG selects AHUs with streamlined internal profiles and high-surface-area filters. This reduces internal static pressure, allowing fans to operate at lower speeds while maintaining design airflow.

2. Thermal Envelope Integrity

• L1 Leakage Class Casing: To lower BEI, every watt of cooling must reach the occupied space. We specify double-skin casings with certified L1 leakage ratings and thermal break profiles. This prevents "thermal migration" and external condensation, ensuring no energy is wasted in the mechanical room.

• High-Efficiency Coils: Our units feature optimized fin-per-inch (FPI) counts and row depths to maximize heat exchange efficiency, allowing for higher chilled water setpoints which reduce the workload on the central chiller plant.

Operational Intelligence & TNB Savings

EKG (Malaysia) SDN BHD ensures that your Low BEI AHU is a smart asset that adapts to the building’s real-time needs:

• Demand-Controlled Ventilation (DCV):

  By integrating Variable Frequency Drives (VFDs) with CO2 and occupancy sensors, the AHU modulates airflow based on actual demand. This prevents the energy waste of cooling empty rooms, a major contributor to high BEI scores in commercial offices and showrooms.

• Total 3D BIM Coordination:

  A "clash-free" installation is essential for efficiency. We use 3D BIM modeling to ensure perfectly linear duct runs. By avoiding unnecessary bends and "snaking" ductwork, we minimize External Static Pressure (ESP), which allows the AHU to operate at its Best Efficiency Point (BEP).

• Energy Recovery Integration:

  For buildings with high fresh air requirements, we integrate Energy Recovery Ventilators (ERV) or thermal wheels. This "recycles" the coolth from exhaust air to pre-condition incoming outdoor air, drastically lowering the energy intensity of the ventilation cycle.
