In the 2026 engineering landscape, AHU Footprint and Clearance Compliance Testing is a critical statutory requirement. Under the Energy Efficiency and Conservation Act (EECA) 2024 and the latest MS 1525:2024 standards, an Air Handling Unit that lacks proper service clearance is considered a non-compliant asset. Restricted access leads to poor coil cleaning and delayed filter changes, which significantly increases Specific Fan Power (SFP) and risks the building’s mandatory Energy Intensity Label.
At EKG (Malaysia) SDN BHD, we utilize 3D laser scanning and "Digital Twin" verification to ensure your AHU installation is sterile, silent, and statutory-compliant.
Clearance is not just about physical space; it is about maintaining the unit’s design efficiency over its 20-year lifecycle.
Coil Pull-out Space: We verify that the "Maintenance Footprint" includes enough lateral clearance to fully remove the cooling coil. Without this, the coil cannot be deep-cleaned, leading to high pressure drops and "Energy Theft."
Filter Access & Seal Integrity: Adequate clearance ensures that technicians can stand directly in front of the filter banks. This prevents "diagonal seating," which causes air bypass and violates DOSH (JKKP) hygiene standards.
Motor & Fan Removal: For units utilizing modular IE5 EC Fan Walls, we verify "Swing-Clearance" for individual fan modules, allowing for rapid, zero-downtime maintenance.
Our Mechanical Position Testing includes a specific "Access Audit" using the following benchmarks:
| Component | Minimum Compliance Clearance | Engineering Purpose |
| Service Side | Unit Width + 300mm | Allows for full coil removal and piping maintenance. |
| Non-Service Side | 600mm | Minimum space for inspection and casing integrity checks. |
| Fan Section | 1000mm (Internal/External) | Required for safe motor handling and VSD/VFD access. |
| Upper Clearance | 500mm to Ceiling/Slab | Necessary for the removal of top-mounted actuators and sensors. |
As of January 1, 2026, "As-Built Clearance" documentation is required for the mandatory 5-year periodic energy audit.
Energy Commission (ST) Audit: The ST auditor will verify that all sub-meters and sensors are accessible. If a sensor is blocked by a structural beam, the unit may be flagged as non-auditable.
BIM Digital Twin (LOD 500): We scan the as-installed footprint and overlay it with the original LOD 400 BIM model. This proves to the authorities that the "Path of Maintenance" is preserved and unblocked by other MEP services.
Fire & Life Safety: We ensure that the AHU footprint does not encroach on mandatory fire escape routes or obstruct fire sprinklers and smoke detectors within the plant room.
Technical Integrity: Our footprint testing is conducted by mechanical engineers who understand the ergonomics of HVAC maintenance in tropical climates.
Zero-Clash Resolution: If a footprint violation is found during the rigging phase, we provide immediate 3D-coordinated solutions, such as shifting piping headers or utilizing modular "slim-line" components.
Audit-Ready Handover: We provide a certified Clearance Compliance Map, protecting your building’s energy license and ensuring a "First-Time-Right" statutory audit.
