The Client
The Carnarvon Police & Justice Complex was developed as part of the Western Australian Government’s investment into regional law and order infrastructure. The facility combines police services, courts, and a children’s justice centre in a single modern precinct, providing much-needed services for the community of Carnarvon.
EMCO was appointed as builder, with Cox Architects designing the facility and Wood & Grieve Engineers providing mechanical consultancy. Envar was engaged to deliver the full mechanical services scope, valued at $3.575M, ensuring reliable comfort and environmental control across the complex.
What we achieved with our customer
Envar delivered a full mechanical services solution for the Carnarvon Police & Justice Complex, ensuring robust and efficient climate control across its diverse range of facilities. The central plant installation comprised air-cooled chillers with chilled water circulation systems, supported by heating pumps and a network of chilled and heating water fan coil units to provide consistent comfort throughout offices, police facilities, and justice buildings.
Within the court building, air handling units were installed to deliver reliable air distribution and climate control in public and judicial spaces. Specialist chilled water CRAC units were also integrated to protect critical IT and server environments, maintaining stable conditions essential for sensitive equipment.
Ventilation systems were tailored to the unique requirements of the complex, including dedicated exhaust solutions for holding cells, toilet facilities, and the loading bay. These systems provided a safe and controlled environment by effectively managing air quality in high-risk and high-use areas.
To unify all services, Envar implemented a fully integrated Building Management System (BMS), enabling precinct-wide centralised control, monitoring, and optimisation. This not only improved operational efficiency but also empowered building managers to maintain secure, reliable, and energy-efficient conditions across the entire complex.
