How we helped
Trinity conducted an air quality impact assessment for the Buranda TOD Plot 2 project, using the GRAL model.
The main focus of the assessment was air emissions from the basement carpark mechanical ventilation system. Trinity identified the key pollutants and emissions sources associated with cars travelling within the basement carparks and estimated the pollutant emission rates for the proposed mechanical ventilation system exhausts.
The Graz Lagrangian Model (GRAL) was chosen for the modelling due to the complex nature of the structures, including towers on a shared podium and towers at a variety of angles. These cannot be accurately modelled using traditional air dispersion models such as CALPUFF or AERMOD. Air flows over and around these structures require a more sophisticated approach, making GRAL the more suitable model.
Trinity’s expertise and vast technical knowledge in air dispersion modelling provided assurance regarding the accuracy of the predicted results, delivering a reliable air quality assessment and minimising risks associated with emissions from the car park ventilation system.
Our detailed approach helped our client to avoid any potential impacts onsite, even under conservative estimations.
About the project
The Buranda TOD (Transit-Oriented Development) Plot 2 project is an extension of the Buranda TOD Stage 1 project in Woolloongabba.
In addition to the two mixed-use towers consisting of student accommodation apartments and retail outlets, Plot 2 introduces four new towers of varying heights, covering residential, student accommodation and mixed-use commercial office towers. The four buildings will be interconnected via a fully integrated ground-level plaza.
