A Green Building AHU is the mechanical heart of a sustainable facility, designed to exceed the baseline performance standards of MS 1525 and maximize points under the Green Building Index (GBI) or LEED rating systems. Under the EECA 2024, these units are now essential tools for maintaining a building's mandatory energy star rating in Malaysia.
EKG (Malaysia) SDN BHD specializes in engineering AHU solutions that focus on "Active Design" strategies—reducing Building Energy Intensity (BEI) while ensuring superior Indoor Environmental Quality (EQ).
In a Green Building, the AHU must minimize electrical "parasitic" loads. EKG achieves this through:
Ultra-Low Specific Fan Power (SFP): While MS 1525 sets a limit of 1.6 kW per cubic meter per second, Green Building standards often push for an SFP below 1.1 kW per cubic meter per second. We achieve this by using Direct-Drive EC Fans (IE5) and optimizing internal unit aerodynamics.
Variable Air Volume (VAV) & VFDs: A green AHU never runs at a single speed. We integrate Variable Frequency Drives that modulate motor speed based on real-time cooling demand, which can reduce fan energy consumption by up to 50 percent.
High-Efficiency Motors: Every unit we install features premium-efficiency motors (IE4 or IE5), ensuring that nearly 95 percent of the electrical energy is converted into mechanical work.
Green buildings prioritize the wellbeing of occupants.
Demand-Controlled Ventilation (DCV): We install CO2 sensors in the return air path. The AHU automatically increases fresh air intake only when occupancy rises, ensuring high oxygen levels and low pollutant concentrations without wasting energy during low-occupancy hours.
Advanced Filtration (MERV 13/14): To meet GBI and LEED requirements for "Indoor Air Pollutants," we use high-efficiency filters that capture fine particulates, bacteria, and allergens, providing a healthier environment for Grade-A office spaces.
TB2 Thermal Integrity: Our AHUs utilize TB2-rated thermal breaks in the casing. This prevents external condensation ("sweating") and mold growth, ensuring the mechanical room and ductwork remain sterile and dry.
In Malaysia’s tropical climate, cooling fresh air is the most energy-intensive task.
Enthalpy Recovery Wheels (ERW): We integrate Thermal Wheels that recover both sensible heat (temperature) and latent heat (humidity) from exhaust air.
Carbon Footprint Impact: An ERW can reduce the total cooling load on your central chillers by up to 30 percent, directly lowering your building's Scope 2 carbon emissions.
Technical Integrity: We provide the psychrometric calculations and energy modeling data required by GBI Facilitators and LEED APs for project certification.
3D BIM Coordination: High-performance AHUs with ERWs are larger than standard units. We use 3D BIM modeling to ensure a "clash-free" installation in your mechanical room.
BOMBA Compliance: All green materials—including high-efficiency PU foam and non-metallic thermal breaks—are fire-rated (Class 0 or B1) to meet safety standards.
