Indoor air quality
People spend most of their lives indoors. We simulate how air moves through a room so you can see where it is fresh, where it stagnates, and what the ventilation is really doing.

The question
Does the ventilation reach the people?
A ventilation system is sized to deliver a certain volume of fresh air per hour. That number says nothing about where the air actually goes. Supply air can short-circuit straight to the extract, leaving pockets of the room barely ventilated while the flow meter reports full compliance.
CFD simulation shows the distribution instead of the average. It maps where fresh air arrives, where stale air lingers, and how long a pollutant released in one part of the room takes to clear.
What we simulate
Air, pollutants and the people in the room
We build the room from your drawings, including the furniture, the equipment and the occupants, since bodies are both obstacles and heat sources that drive the flow. Supply and extract terminals are modelled with their real geometry and flow rates.
From the solved flow field we derive the quantities that matter for a decision: local air change effectiveness, age of air, and the concentration field of whatever the space needs to control, whether that is CO2, a solvent, or particles carried from a neighbouring zone.
Where it is used
Offices, schools, laboratories and public buildings
The study is most valuable when a space has to perform and the layout is unusual: high occupancy, deep floor plates, atria, or a renovation where the ventilation was designed for a different use.
It is also the tool for comparing options. Two diffuser layouts that look equivalent on paper can behave very differently once the room and its occupants are in the model, and the simulation shows which one to build before anything is installed.
