DesignBuilder CFD Engine
Butterfly, Ladybug (Donated by NEAPOLI)

Computational Fluid Dynamics (CFD) is a powerful tool for analysing fluid flows and heat transfer both inside and outside of buildings.

Using Simulation CFD the project can get more accurate quantitative results to optimise the airflow and thermal comfort of interior rooms and spaces.

CFD analyses in the context of Environmental Design and Engineering can be classified into three major categories:

Mechanical Ventilation
External Flow or Wind Loading
Natural Ventilation
Heating air conditioning

NEAPOLI has successfully utilised CFD to optimise Displacement Ventilation, the distribution of fresh air (Air Change Effectiveness) using swirl diffusers and outdoor airflows around buildings to optimise exterior thermal comfort.

Computational Fluid Dynamics (CFD) analysis can be used by building designers to calculate the temperature, velocity and other fluid properties through a 3D domain. CFD is used to answer design questions such as:

What sort of temperature distribution could we expect in an atrium under clear sky summer conditions?
Will the arrangement of supply diffusers provide adequate air movement?
Is the location of the air-conditioning inlets and outlets going to provide good comfort conditions?
Will natural ventilation provide occupants with adequate comfort in the summer?
