In the regulatory landscape of 2026, a Low BEI (Building Energy Intensity) AHU is the cornerstone of any facility aiming to comply with the mandatory EECA 2024 star-rating system. Since HVAC systems typically account for over 50% of a commercial building’s energy consumption, the Air Handling Unit must be engineered as a high-precision energy-saving engine rather than just a ventilation box.
At EKG (Malaysia) SDN BHD, we specialize in AHU configurations that drive your BEI ($kWh/m^2/year$) down into the 4-star and 5-star brackets through superior mechanical and digital integration.
To achieve a Low BEI rating, the AHU must minimize "Parasitic Power" while maximizing thermal delivery.
Ultra-Low SFP (Specific Fan Power): We target an SFP of < 1.1 $kW/m^3/s$, significantly better than the MS 1525 baseline. This is achieved by utilizing IE5 EC Plug Fan Arrays, which eliminate the 5–12% energy loss found in legacy belt-driven systems.
Total Enthalpy Recovery (ERW): In Malaysia's high-humidity climate, we integrate Enthalpy Recovery Wheels to pre-condition outdoor air using the building’s exhaust air. This "thermal recycling" reduces the required chiller tonnage and lowers the total electrical load.
L1-Class Leakage & TB2 Thermal Integrity: A Low BEI unit must be airtight. We utilize L1-class seals and TB2 thermal breaks to ensure no treated air is wasted and no external heat "leaks" into the system.
The physical configuration of the AHU is just as important as the components inside it.
Low Face-Velocity Design: By increasing the cross-sectional area of the AHU, we maintain air velocity through coils and filters at < 2.0 m/s. This exponentially reduces the air-side resistance, allowing the fan to run at lower, more efficient speeds.
Static Regain Optimization: Our layouts include discharge plenums designed to convert velocity pressure into static pressure. This "regained" energy allows the system to satisfy duct pressure requirements with less motor work.
| Metric | Standard AHU (Baseline) | EKG Low BEI AHU |
| SFP Rating | 1.6 - 2.2 $kW/m^3/s$ | < 1.1 $kW/m^3/s$ |
| Motor Efficiency | IE2 / IE3 AC Motor | IE5 EC Direct-Drive Array |
| Energy Recovery | None | Integrated Enthalpy Wheel |
| Casing Leakage | L3 (Standard) | L1 (Precision Sealed) |
| Control Logic | Constant Volume | Smart Demand-Controlled (DCV) |
| Compliance | 1-2 Star (Audit Risk) | 4-5 Star (Audit Ready) |
Under the Energy Efficiency and Conservation Act 2024, every "Designated Building" must provide verifiable energy data to the Energy Commission (Suruhanjaya Tenaga).
Smart Energy Metering: Every EKG Low BEI AHU comes equipped with integrated kWh meters and digital pressure transducers.
IoT Performance Monitoring: We provide real-time data feeds to your Energy Management System (EnMS) via BACnet or Modbus, allowing for automated speed modulation based on actual building occupancy.
Predictive Maintenance: Sensors monitor motor vibration and filter pressure, ensuring the unit stays at its "Best Efficiency Point" (BEP) and preventing the efficiency drift that usually drives up BEI over time.
Technical Integrity: We provide the full SFP and BEI impact projections required by Registered Energy Managers (REM) for statutory reporting.
3D BIM Coordination: Our 3D modeling process ensures that these high-efficiency (often larger) units are perfectly placed for optimal aerodynamic airflow.
BOMBA-Compliant Safety: All Low BEI materials, including high-performance insulation and seals, are fire-rated (Class 0 or B1).
