Computational Fluid Dynamics

Both external and internal building analyses can be performed by using the DesignBuilder CFD module. This is a sophisticated but extremely user-friendly module that integrates seamlessly with the main simulation package.

Standard tools used for model creation are used to specify parameters and place different diffuser types, exhaust grilles, heating panels etc. Boundary conditions can be user specified or simply imported from a previous EnergyPlus simulation run.

This is ideal for studying external wind effects, natural ventilation, stack effect, thermal comfort and air change effectiveness. It is equally suited for advanced studies of displacement ventilation systems or specialized ventilation studies e.g. in hospital theatres. The powerful graphic output facility enables users to view data in a combination of vectors, contours, filled contours etc.

Age-of-Air contour data can be used directly for Green Star IEQ-2 air change effectiveness studies and reporting.
