A Building Ventilation Survey is a comprehensive mechanical and volumetric "health check" for your entire property. In Kuala Lumpur’s tropical climate, ventilation systems are often the largest source of energy waste and the primary cause of indoor humidity issues. Over time, building layouts change, staff counts increase, and fans degrade, leading to a "Ventilation Gap" where the original design no longer matches the actual needs of the occupants.
As part of a Ventilation Systems Audit, EKG performs this survey to map every cubic meter of air moving through your facility, identifying exactly where your power is being wasted and where your air quality is failing.
We look beyond the surface to find the hidden mechanical inefficiencies:
Volumetric Flow Mapping: We measure the actual supply, return, and exhaust air at every major AHU and fan unit. We often find that "Design Airflow" has dropped by 20 to 30 percent due to dirty coils or slipping belts.
Fresh Air Adequacy: We verify that your Fresh Air Intakes are providing enough oxygen to meet 2026 DOSH (JKKP) health standards.
Thermal Comfort Analysis: We map "Hot Spots" and "Drafty Zones" to determine if your air distribution (diffusers and dampers) is balanced correctly.
Pressurization Balance: We check if the building is "Positive" (keeping heat out) or "Negative" (sucking humidity in).
Our engineers use a data-driven approach to audit your mechanical infrastructure:
Fan Performance Testing: We measure the static pressure and amperage of every fan. If a fan is running at high speed but moving low air volume, it indicates an internal mechanical "choke" or a severely dirty impeller.
Ductwork Leakage Audit: We use ultrasonic leak detectors to find holes in the supply ducts. Leaking 15 percent of your cold air into a ceiling void is one of the most common causes of high TNB bills.
CO2 and Humidity Profiling: We place data loggers throughout the building to identify where air is "stagnant." These zones are often the result of poor duct design or failed motorized dampers.
Control System Calibration: We verify that your Variable Frequency Drive (VFD) and Building Management System (BMS) are actually reading the correct data from the field sensors.
A Building Ventilation Survey is the first step toward massive energy savings. Most buildings over-ventilate certain areas while starving others.
Precision Speed Control: By re-balancing the air, we can often lower the overall fan speeds while improving air quality.
The Logic: Because of the Cube Law, a 20 percent reduction in fan speed results in a nearly 50 percent reduction in power consumption. A Ventilation Survey provides the "Roadmap" to safely lower your VFD frequencies.
