In the 2026 landscape of EECA 2024 and MS 1525:2024, achieving a Low Building Energy Intensity (BEI) in commercial offices requires a move away from "one-size-fits-all" ventilation. For an office to secure a 4-star or 5-star energy rating, the AHU layout must be engineered to handle high-density occupancy during the day while ramping down to near-zero consumption after hours.
At EKG (Malaysia) SDN BHD, we specialize in two primary layout archetypes designed to minimize the electrical footprint of Malaysian corporate spaces.
This is the gold standard for modern "Green Offices." A single high-efficiency AHU serves multiple office zones (meeting rooms, open-plan areas, and executive suites), each controlled by a localized VAV box.
Static Pressure Reset: As VAV dampers close in empty meeting rooms, the AHU uses its VSD (Variable Speed Drive) to lower the fan speed. This prevents "duct ballooning" and ensures the Specific Fan Power (SFP) stays optimized at all times.
Aerodynamic Header Design: We utilize 3D BIM Coordination to ensure the main supply header uses gradual, vane-guided take-offs to each zone. This maintains Laminar Flow and reduces the total static pressure the fan must overcome.
Instead of one massive central plant, we utilize smaller, high-efficiency AHUs located in dedicated plant rooms on each floor.
Reduced Duct Friction: By placing the AHU closer to the occupied space, we eliminate long, high-resistance vertical duct runs. Shorter duct paths mean lower External Static Pressure (ESP), allowing for smaller, quieter IE5 EC Fan Arrays.
Localized Fresh Air Treatment: Each floor's AHU can be equipped with its own Enthalpy Recovery Wheel (ERW). This allows the building to treat fresh air only for the floors currently in use, a critical feature for offices with flexible working hours.

A. Acoustic Buffer Zone Integration
Office AHUs must be silent. We position the plant room adjacent to "transient zones" (like lift lobbies) and utilize a Decompression Plenum. This allows us to use low-resistance acoustic lining, lowering the pressure drop and keeping the SFP below 1.1 $kW/m^3/s$.
B. Demand-Controlled Ventilation (DCV)
In a Green Office, air quality is paramount. We place CO2 sensors in the return air path of the layout. The system automatically adjusts the fresh air intake based on real-time occupancy, ensuring the office never "over-cools" an empty space—the #1 cause of high BEI in Malaysia.
C. TB2 Thermal Integrity
Our double-skin casing with TB2 thermal breaks prevents condensation and mold growth. This protects the IAQ (Indoor Air Quality) for employees while ensuring the "coolth" generated by the coils is delivered with zero thermal leakage.
Technical Integrity: We provide the SFP and BEI impact projections required by Registered Energy Managers (REM) for statutory audits and GBI submissions.
Precision BIM Coordination: Our 3D modeling ensures that complex VAV networks and ERW units fit perfectly within your ceiling void without clashing with fire or electrical services.
BOMBA-Compliant Safety: All office-grade materials, including acoustic liners and insulation, are fire-rated (Class 0 or B1).
