Justin Wong - erbas™ - Engineers for Building Services

Justin is an experienced senior commissioning engineer with extensive energy modelling experience of façade and HVAC systems to drive verifiable energy and occupant comfort performance in design through to operation. The practical use of energy simulation has enabled him to develop well-rounded understanding of the interactions between different systems in buildings. This has provided a strong technical basis towards his commissioning experience through the delivering of commissioning management and commission agent services to both commercial and social infrastructures in CBD and regional areas. Justin has developed a workflow driven approach that combined the best of both CIBSE and ASHRAE commissioning guidelines and codes, together with the relevant Australian Standards to streamline the services commissioning process. This has allowed our services to adopt a systematic approach and well documented process. 

One significant advantage of having Justin on any project is his stakeholder engagement experience working and educating services contractors on projects without commissioning requirements. In particular, he has also developed extensive experiences working with construction partners in the Hospital and Aged Care sector, where there are greater emphasis on the life and fire safety systems as well as early access requirements.

Through his commissioning management experience, he has acquired significant monthly post PC monitoring and building tuning experience to ensure streamline handover of the services to the client as well as providing strategic advisory in relation to NABERS operational performance. Throughout the years, he has developed good working knowledge of the relevant tenant sustainability obligation from various sustainability rating systems, having prior experience providing energy, water and emission performance of mixed use assets for property funds managers. In addition, he is also well-verse on the sustainability implications of the various interfaces between base building and tenant services in the context of integrated fit-out delivery model.
