Airflow Simulation (CFD)

Airflow analysis examines external pressures and airflow patterns around buildings and is used in a wide range of applications, including internal comfort. The results are clearly presented using animation for airflows.

Our in-house modelling team use state-of-the-art Computational Fluid Dynamics (CFD) techniques, originally developed for the aeronautical industry as an alternative to wind tunnel testing.

The use of this sophisticated methodology is essential when assessing building performance.

Dynamic Thermal Modelling

IN2 has vast experience in Thermal Analysis of all building types; ensuring passive design techniques are incorporated into the design. Thermal analysis enables accurate natural ventilation strategies by simulating predicted performance against specific climatic data, and advises us on Building Form, Massing and Orientation, Solar shading and Window/Vent arrangements.

The successful design of modern buildings, incorporating Atria and Intelligent Façades, relies on these sophisticated modelling techniques.


• Essential in design of low energy buildings

• Relies on local climatic data

• Eliminates expensive air conditioning systems

• Greatly reduces running costs

Lighting Simulation

Good daylighting design in buildings can result in significant energy savings, as well as improving the quality of the internal space.

IN2 Engineering simulate daylighting for buildings both externally (typically at Masterplan stage) and internally, by predicting Daylight Factors


IN2 utilises Building Information Modelling (BIM) to facilitate collaborative, co-ordinated working within design teams. BIM enables virtual construction of a building prior to its actual physical construction, in order to reduce uncertainty, improve safety, work out problems, and simulate and analyse potential impacts. BIM also prevents errors by enabling conflict or 'clash detection' whereby the computer model visually highlights to the team where parts of the building (e.g.: structural frame and building services pipes or ducts) may wrongly intersect.

Quantities and shared properties of materials can be extracted easily. Scopes of work can be isolated and defined. Systems, assemblies and sequences can be shown in a relative scale with the entire building or group of buildings.
