FEA Consulting Singapore
Wind analysis is at the core of what we do at our Singapore CFD consulting office in BroadTech Engineering.
BroadTech Engineering uses advanced wind engineering (IL: wind engineering) simulation and numerical analysis methods such as industry standard computational fluid dynamics (CFD) simulation software tools, CFD modeling to determine the probability of wind energy availability.
Through CFD analysis, we are able to help you to accurately simulate and identify the representative climatic wind conditions of a particular site, such as the wind flow speed, intensity of wind flow turbulence, Wind shear.
This in-depth CFD flow analysis through the use of CFD simulations (Computational Fluid Dynamics simulation) makes it possible for you to identify and optimize the best building design layouts, have a clearer understanding of how wind conditions affect your engineering design and consequently maximize the building energy efficiency.
will help to identify the best wind turbine positions output.
Importance of Wind Analysis in BIM
Wind resource is a fundamental and important factor to evaluate and take into account in practically any outdoor engineering projects.
Outdoor structural engineering projects all need the use of fluid dynamic analysis to get the most accurate estimations of the wind resource available to make accurate and optimized engineering design decision early in the engineering development phase, justify investor financing and smooth daily operation.
Natural Air Ventilation
Having an Active Airflow and high air quality is an extremely important aspect of creating an urban living environment that is conducive to facilitating human comfort.
An actively Moving air ensures a continuous circulation of fresh air within a living space, this helps occupants in the area to experience lower thermal temperatures and prevents air from getting stagnant and becoming stale.
Advantages of Wind Analysis
Using Engineering airflow simulation software such as ANSYS Fluent, our engineering simulation consultants at BroadTech Engineering can harness the processing capabilities of the CFD (Computational fluid analysis) simulation analysis to enable us to carry out airflow modeling to accurately predict how much percentage of the environmental wind flow distribution is affected by a specific high rise building geometric design.
Some of the advantages of doing wind simulation and air dispersion modeling include:
1. Ensure Energy Efficient Thermal Cooling
There are two highly effective passive methods that are commonly adopted by building design consultants as an energy efficient thermal cooling method to cool down the urban built environment while minimizing energy consumption includes
2. Ensure Thermal Comfort
Especially in a hot and humid tropical climate that we are living in Singapore, the constant priority has always been to ensuring the thermal comfort of occupants & residents in the living environment through the use of CFD Thermal analysis
3. Ensure Effective Dispersion of Air Contaminant
Apart from heat dispersion, air dispersion modeling can also be done through CFD simulation.
The enables the tracking of the dispersion of Air Pollutant, which is important to keep the urban city environment healthy for recreational outdoor activities.
4. Ensure Ventilation Performance
A stagnation of air due to low magnitude of wind velocity in a particular zone can negatively affect the quality of our urban built environment.
Air quality modeling through CFD simulation can quickly tell us areas in the whole geographical zone where the air circulation is bad for both the predominantly occurring wind directions patterns (north-east and south-east).
It can also reveal the ventilation performance of high-density Residential Typologies at a Precinct Level.

Natural Ventilation in Building Design
It is the optimization of building structure design for natural ventilation that is the key driving strategy for achieving passive thermal cooling.
In a comprehensive building design, a holistic design approach where both external and internal airflows have to be carefully considered.
External Airflow analysis
An External airflow analysis helps to give the following valuable insights
Internal Airflow Analysis
A building internal airflow simulation analysis allows you to predict and estimate the expected airflow rate and thermal temperature at a specific location of your building information model (BIM), based on different environmental conditions.
It can give valuable design insights into the following:

In conclusion, CFD wind analysis benefits engineering design of building aerodynamics by significantly reducing the time and expense which would otherwise be spent on parametric simulation and design exploration case studies.
Although actual physical Wind tunnel testing is important for design validation, it is extremely expensive, time-consuming. This makes it not practical as a test solution method.
Customers will be provided with fully customizable CFD reports which outline the Methodology, in-depth analysis, and recommendations.
This insight allows our clients to optimize performance and make informed engineering decisions in a scientific, proven manner.

Building design features that Affect Natural Ventilation Performance
Specific morphological and geometrical Urban variables do affect the wind flow behavior in urban area environment, such that the overall wind flow velocity is altered.
Through computational wind analysis on a large number of building design case studies, we can get useful insights into/learn how variations of building design features correlate with its natural ventilation performance.
1. Building Site Coverage & Facade Area
A higher building site coverage and larger facades area generally present itself more as a physical obstacle which can block the overall Wind flow distribution and slow downwind speed throughout the urban city area.
2. Collective Building Orientation
The overall Building orientation needs to be orientated such that it allows the predominant wind directions to naturally flow through the entire city. It is not good to create too many physical building obstacles which can cause an uneven distribution of wind throughout the densely populated urban city area.
3. Building Height
Variability in building height is largely beneficial to encouraging a healthy level of wind flow volume between building spaces to facilitate natural ventilation.
In contrast, a cluster of buildings which has uniform height does not give the wind enough leading spaces for dissipation of flow turbulence by eliminating interactions between flow disturbances and building physical boundaries.
4. Building Shape Geometry
Relative Placement of Sharp Edges
The location placement of building sharp edges relative to each other can affects the fluid dynamic vortex structures at the wake areas where the external wind flow goes over or above buildings.
In addition, it is important to note that the Shape and Profile design of the Building roof can influence whether environmental wind flow can enter the in-between building spaces.
Some building shapes and design does allow wind to flow through them while others tend to retain or deflect wind flow more.
Deep Canyon Designs
Natural Wind fluid flow will decrease when the building has deep and long canyons designs.
As a general industry rule of thumb, building designs with long slabs that shield the wind entrance should be avoided as it results in a long time for wind to exit.
5. Building Relative Arrangement
As a rule of thumb, buildings should always be arranged to give clear passage for the wind to flow through the city. When there are limited choices available for direct clear openings, staggering the buildings will help the wind flow to permeate through the urban fabric indirectly.
