Airflow analysis


The wind’s direction and speed in different areas of a project are not always obvious or intuitive. The shape of a design and its neighbouring buildings can funnel winds in surprising ways, making some spaces unusable at certain times of the year.

Don’t rely on assumptions to make critical decisions that might affect the accessibility, function, and safety of your project’s outdoor spaces.

Why airflow analysis matters


Understanding the impacts of wind can be complicated. Wind patterns change throughout the year and local directions and speeds are dominated by the physical features in their path.

Without data, and an ability to visualize it, teams can spend hours debating the challenges based on personal assumptions of wind flows and climate patterns.

Experts talk about downwashes and tunneling effects, but only quantitative and interactive analysis can really bring airflow to life—guiding your designs and equipping you with the hard data and powerful visuals you need to explain design choices to stakeholders.

How it works


Orbital Stack’s Airflow analysis examines a location’s average wind speeds from a given direction, ultimately revealing potential issues with usability, comfort, and safety.

Climate-scaled wind flow plots and streamlines are mapped on to a virtual model of a proposed design in the context of historical climate data and the local built environment. These visual guides show how winds reach critical areas of the site, offering important insights into local directionality and informing the best choices for mitigations.

What users are saying


“We cannot see wind—and it can be hard to explain to our clients—but Orbital Stack allows us to do just that. The tool brings an expert level of visibility into how wind—and solar—impacts pedestrian environments. With a better line of sight, we can alter illustrative designs earlier and, with better visuals, empower teams to make more informed decisions for people-first spaces.” — Allison Piehn, Commercial Director, Studio Egret West Limited
