Computational fluid dynamics modelling of ventilation in road tunnels: enhancing air quality and safety
Ventilation units within vehicle tunnels play a pivotal role in ensuring safety and optimal air quality for
occupants. These units are used to assist with propelling air from one end to the opposite end of the tunnel.
Computational fluid dynamics (CFD) has emerged as an invaluable design tool for engineers and stakeholders,
offering simulated insights and data to optimise safety and efficiency in tunnel projects. This paper
emphasises the advantages of CFD for road tunnel ventilation design, showcases a case study involving
impulse fans, and highlights the positive effects on project costs and overall tunnel ventilation performance.

Development of a whole-house energy rating tool for new housing
In 2019, Australian energy ministers agreed on the need for the Trajectory for Low Energy Buildings (the Trajectory). One of the key aspects in the Trajectory for residential buildings is to expand the Nationwide House Energy Rating Scheme (NatHERS) to offer nationally accredited whole-of-home (WoH) tools to enable compliance requirements in the National Construction Code (NCC).
