- Regulatory Liaison: We facilitate in-principle agreement from the Building Authority (BA) on methodologies prior to formal submission.
CFD Simulation in Building Design
We utilize advanced Computational Fluid Dynamics (CFD) to optimize natural ventilation. Figure 1 below illustrates the airflow patterns through building louvres. Figure 2 shows a contour map displaying the velocity distribution as air passes through the louvres.

Physical Modeling – Wind Tunnel Test
Wind tunnel is located in Hong Kong.
Precision, accurate, and regular calibrated instruments includes hot-wire anemometer, omni-directional sensors, cobra probe, electronic pressure scanners, force gauge, together with automatic sampling software, which can measure wind speed, wind direction, wind pressure, turbulence intensities…etc.

LASER-Aided Flow Visualization
Apart from flow measurement, LASER-Aided Flow Visualisation provide another insight of fluid flow. The fog is generated by fog machine and injected into wind tunnel for tracing the flow. A laser plane is used for illuminating the fog.
