Urban Microclimate Simulations

Optimize urban and building designs for wind comfort and natural ventilation using cloud-based CFD simulation.

CFD for Wind Analysis and Thermal Comfort

Wind comfort and thermal comfort in public spaces and private spaces are essential factors in ensuring good and safe living conditions. In urban microclimates, wind engineering is at the core of the design cycles of buildings.

With complex urban areas and modern architectural designs, high-performance analysis tools are in need to efficiently and accurately predict pedestrian-level wind comfort and thermal comfort in buildings through natural ventilation.

Using SimScale’s cloud-based CFD simulation, you can:

  • Run multiple CFD simulations in parallel
  • Run simulations quickly with an easy-to-learn interface
  • Avoid manual updates, installation, maintenance, and any related fees

Urban Microclimate Applications

Pedestrian-Level Wind Simulation

SimScale enables fast and accurate wind simulations based on industry standards, such as Lawson, Davenport, and NEN 8100, to predict the behavior of wind flow around buildings early in the process.

Make informed design decisions with a wind modelling assessment that includes:

  • Local meteorological data
  • 36 wind rose-driven directions to be simultaneously simulated
  • Planned/existing building aerodynamics
  • Selected comfort criteria/wind comfort standard data
  • Wind effects such as tunnel throttling or vorticity

Passive & Natural Ventilation Simulation

SimScale enables engineers to analyze the performance of a natural or passive ventilation system early in the design cycle without the high cost of hardware and the undesirably steep learning curves of traditional, on-premises tools.

Make informed design decisions even in specific scenarios:

  • With adjustable windows and doors (inlets and outlets)
  • In climates that allow for natural ventilation
  • Where devices (i.e. earth tubes) are employed to facilitate passive ventilation
  • With environmentally conscious standards (for example, ASHRAE 55)

Customer Success

Zaha Hadid Architects Evaluated Climate Impacts on Their Sustainable Design Using SimScale.

In this analysis, Zaha Hadid Architects ran a wind analysis study of the headquarters building design for their client Oppo. Using SimScale’s CFD simulations, they ran parallel simulations in 6 wind directions to evaluate the frequency and intensity of the annual wind profile. They managed to achieve fast and accurate results in less than 2 hours.

Numbers and schematics showing the following: 6 wind directions simulated in parallel and fast and accurate results in 108 min
