In the 2026 landscape of the Energy Efficiency and Conservation Act (EECA) 2024, Fresh Air HVAC has evolved from a basic ventilation requirement into a sophisticated energy-management strategy. In Malaysia, bringing in fresh outdoor air is essential for health but traditionally comes with a massive energy penalty due to high heat and humidity.
At EKG (Malaysia) SDN BHD, we specialize in "Smart Fresh Air" systems that utilize Energy Recovery Ventilation (ERV) to provide 100% fresh air while maintaining a low Building Energy Intensity (BEI).
Modern buildings are tightly sealed to save energy, but without a dedicated fresh air HVAC strategy, indoor air becomes "stale," leading to high CO2 levels, VOC buildup, and mold growth.
ASHRAE 62.1 Standards: We design systems to meet or exceed these international ventilation benchmarks, ensuring that every occupant has access to clean, oxygenated air.
The Dilution Principle: Constant fresh air exchange dilutes airborne pathogens and pollutants, which is a key requirement for MOH clinical compliance and healthy office environments.
Pressurization: A proper fresh air HVAC system maintains a "Positive" or "Neutral" pressure, preventing unfiltered dust and humid air from leaking in through doors and windows.
In Kuala Lumpur's climate, outdoor air is typically 33 degrees Celsius with 80% humidity. Cooling this air directly with a standard air conditioner is extremely expensive.
Energy Recovery Ventilation (ERV): This is the heart of a modern fresh air HVAC system. It uses the "coolth" from the air being exhausted to pre-chill the incoming fresh air.
Sensible + Latent Recovery: Our systems don't just transfer temperature; they transfer moisture. A desiccant-coated enthalpy core strips the humidity from the fresh air, reducing the dehumidification load on your chiller by up to 75%.
Decoupled Loads: By handling the fresh air separately (often via a DOAS - Dedicated Outdoor Air System), the main HVAC units can focus purely on the internal room temperature.
To meet the 2026 statutory energy audits, EKG Fresh Air HVAC systems incorporate:
| Component | Specification | Benefit |
| Drive System | IE5 Direct-Drive EC Fans | Ultra-efficient air movement with precise speed control. |
| Filtration | F7 + PM2.5 + Carbon | Removes urban haze, dust, and odors before air enters the building. |
| Fan Energy | SFP < 0.9 kW/m3/s | Well below the EECA 2024 legal limit of 1.1 kW/m3/s. |
| Control Logic | Demand Control (DCV) | Ramps ventilation up/down based on real-time occupancy (CO2 sensors). |
| Casing | TB2 Thermal Break | Prevents "sweating" and energy loss in high-humidity zones. |
The most advanced feature of our fresh air HVAC systems is the ability to respond to the building's "heartbeat."
CO2 Monitoring: Sensors detect when a meeting room or hall is occupied and signal the ERV to increase fresh air.
Energy Savings: When the building is empty (e.g., lunch hours or night shifts), the system automatically ramps down. This prevents the unnecessary cooling of outdoor air, saving up to 40% in energy costs.
EnMS Integration: All airflow and energy data are fed to your Energy Management System (EnMS) for the 2026 statutory energy reports required by the Energy Commission (ST).
Technical Integrity: We provide the Psychrometric Analysis and Air Balance Reports required for professional engineering and building certifications.
3D BIM Coordination: We model the fresh air ducting and louvers in 3D to ensure zero clashes with other services and optimal building aesthetics.
BOMBA-Compliant Safety: All materials used, from the recovery media to the non-shedding insulation, are fire-rated (Class 0 or B1).
