BEI Optimized Air Handling Units

BEI Optimized Air Handling Units by EKG (Malaysia) SDN BHD

In the regulatory landscape of Kuala Lumpur and Selangor, the Building Energy Intensity (BEI)—measured in $kWh/m^2/year$—is the definitive metric for energy performance. Under the EECA 2024, large commercial buildings are mandated to maintain specific energy benchmarks. Since HVAC systems can account for up to 60% of a building's energy consumption, EKG (Malaysia) SDN BHD specializes in engineering BEI Optimized Air Handling Units that act as the primary driver for lowering your facility's energy footprint. 

Our optimization strategies are designed to meet MS 1525 standards and secure the mandatory star ratings required by the Energy Commission.

Core Engineering Pillars for BEI Reduction

To effectively lower a building's BEI, the AHU must minimize its own power consumption while reducing the load on the central cooling plant.

1. Specific Fan Power (SFP) Minimization

• EC Plug Fan Integration: We utilize IE4 and IE5 rated Electronically Commutated (EC) fans. These direct-drive systems eliminate the friction losses of belts and pulleys, ensuring that the wattage consumed per unit of air delivered is at the absolute minimum.

• Low-Resistance Internal Geometry: EKG selects units with streamlined internal profiles. By reducing internal static pressure, the fan motor does not have to "fight" the unit itself, resulting in a lower $kW$ draw.

2. Thermal Envelope Integrity (TB2 & L1)

• Eliminating Energy Leakage: We specify double-skin casings with TB2 Thermal Break profiles. This prevents thermal migration through the cabinet, ensuring that the "coolth" generated by the coil reaches the building zones rather than cooling the mechanical room.

• Certified L1 Air Leakage: Our optimized units are precision-sealed to meeting the highest leakage standards. Preventing treated air from escaping the unit is a critical mechanical step in lowering the total $kWh$ consumed by the building.

Strategic Operational Optimization

EKG (Malaysia) SDN BHD ensures that your BEI-optimized AHU works as a smart component within the building’s ecosystem:

• Demand-Controlled Ventilation (DCV):

  By pairing the AHU with Variable Frequency Drives (VFDs) and CO2 sensors, the system modulates its output based on real-time occupancy. This prevents the energy-intensive process of cooling and filtering air for empty floors, a major factor in driving down BEI scores.

• 3D BIM Coordination for System Efficiency:

  We use 3D BIM modeling to design "clash-free" and aerodynamically optimized duct layouts. By smoothing out the air path and avoiding unnecessary bends, we lower the External Static Pressure (ESP), allowing the fan to operate at its Best Efficiency Point (BEP).

• Energy Recovery Integration:

  In facilities with high fresh air requirements, we integrate thermal wheels or energy recovery ventilators. These components "recycle" energy from exhaust air to pre-condition the hot, humid Malaysian intake air, drastically reducing the thermal load on your chillers.
