In the 2026 Malaysian engineering landscape, a Roof AHU Installation is a high-stakes mechanical operation. Under the Energy Efficiency and Conservation Act (EECA) 2024, rooftop units are subject to intense scrutiny because they are exposed to direct solar radiation and high ambient temperatures. Improper installation leads to "thermal bridging" and air leakage, which are primary causes of Energy Theft and can result in the building failing its mandatory Energy Intensity Label audit.
At EKG (Malaysia) SDN BHD, we ensure rooftop installations are Sterile, Silent, and Statutory-Compliant.
Rooftop placement in dense urban areas like KLCC or TRX requires precision logistics and adherence to the 2026 DOSH (JKKP) Certificate of Fitness (CF) framework.
Certified Spreader Beams: We mandate the use of spreader beams to ensure 100% vertical lift forces. This prevents "side-crushing" of the TB2 Thermal Break casing, preserving the unit's airtightness.
4D Path-of-Entry (POE) Simulation: We utilize LOD 400 BIM data to simulate the lift trajectory, accounting for "Wind Canyons" and ensuring zero clashes with existing rooftop services.
Vibration Decoupling: Every rooftop unit is mounted on an engineered Inertia Base with High-Deflection Spring Isolators. This achieves the NC 30-35 acoustic profile required to prevent mechanical "thrum" from vibrating through the structural slab into the executive floors below.
Rooftop units must be "Hardened" against the tropical Malaysian climate.
UV-Resistant Casing: We verify that the AHU casing is treated with high-reflectivity, UV-stable coatings to reduce solar heat gain.
TB2 Thermal Break Integrity: We ensure that no metal-to-metal contact exists between the internal air stream and the external environment. Any "thermal bridge" will cause external condensation and mold, violating JKKP hygiene mandates.
Weather-Proof Cowls & Louvers: All fresh air intakes are fitted with high-velocity storm louvers and bird screens to prevent moisture carry-over during heavy monsoon rains.
Under MS 1525:2024, a rooftop AHU must be accessible and hygienically sound.
| Compliance Category | Requirement | Engineering Purpose |
| Maintenance Clearance | Unit Width + 300mm | Ensures the coil can be fully pulled out for deep cleaning. |
| Drainage Gradient | 1:100 Precision Slope | Prevents stagnant water and biofilm buildup (JKKP Compliance). |
| Plinth Height | Minimum 300mm | Protects the unit from "ponding" water on the roof during flash floods. |
| Energy Metering | Integrated Modbus/BACnet | Real-time monitoring of Specific Fan Power (SFP) for EECA audits. |
Technical Integrity: Our installations are overseen by mechanical engineers who specialize in the thermodynamics of high-performance rooftop systems.
Zero-Subcontractor Model: We manage the rigging, hoisting, mounting, and statutory commissioning internally to ensure the design intent is never compromised.
GITA Support: Our documented installation reports provide the technical proof required for your business to claim the 100% Green Investment Tax Allowance.
