Computational Fluid Dynamics (CFD) Analysis

Convenience and Accuracy at your fingertips.

Computational Fluid Dynamics (CFD) Analysis refers to the use of simulation software through which air flow and air temperature anywhere in an environment can be predicted. This is achieved by creating a detailed model of the room dimensions, equipment and cooling system on a computer using the CFD software. Through solving a series of complex mathematical equations, a virtual representation of the environment with detailed temperature and air flow data at any given point is generated. This form of analysis is commonly used in the assessment of issues such as pedestrian comfort, facade design, positioning of air intakes and exhausts, and the distribution of contaminants throughout a site and its surroundings. Using CFD software, one can virtually “build” a model based on the design one wishes to analyse. Through application of real-life physics and chemistry, the results generated, images and data, can then be used to predict the performance of that design. CFD provides the convenience and accuracy of seeing one’s design come to life without having to physically build it, and through that, the pros and cons can be accurately predicted and corrected or enhanced at almost no cost to construction at all.



Natural Ventilation (NV) Analysis is performed using computational fluid dynamics (CFD) to study the effects of prevailing winds on the airflow pattern within the spatial spaces. It seeks to identify the most effective building design and layout to be considered sufficiently naturally-ventilated.


Through Mechanical Ventilation (MV) Analysis, the effectiveness of non-ducted circulation fans can be determined though airflow simulations using Computational Fluid Dynamics prior to installation. Important factors such as number of fans, locations to install, blade design, operating speed etc can be ascertain so as to achieve the optimum level of thermal comfort.


Wind-Driven Rain (WDR) Analysis is the study of the horizontal velocity component of rain when driven by wind, resulting in rain falling obliquely. WDR analysis allows the study of the loads on the facade as well as rain ingress into naturally ventilated spaces. This is especially useful for areas such as Drop-Offs, Shelter Walkways, Roof and Sky Gardens.
