- Operating within a live aged care facility with minimal disruption
- Integration with existing HVAC systems under spatial constraints.
Outcomes
Achieved sustained relative humidity of ~64% (exceeding 75% design target)
Delivered superior indoor air quality with PM levels below 6 μg/m³ and CO₂ under 500 ppm
Eliminated condensation and mould risks across a live aged care environment
The Client
About Carinity
Carinity is a leading not-for-profit, Christian-based care organisation with over 75 years of experience delivering integrated community services across Queensland. Formerly known as Queensland Baptist Care, the organisation supports vulnerable individuals through aged care, retirement living, youth services, disability support, chaplaincy, and education programs.
Partnership and Project Significance
Carinity is widely recognised for its strong community focus and commitment to care excellence. AE Smith has maintained a trusted relationship with Carinity since 2015, reinforcing a collaborative partnership approach. The Fairfield Grange project was significant in addressing critical environmental challenges impacting resident wellbeing within a key aged care facility.
What we achieved with our Customer
Project Overview
The Fairfield Grange Aged Care facility, a 96-bed, three-level site, experienced ongoing condensation and mould issues due to inadequate humidity control from the existing HVAC system. AE Smith was engaged to investigate and deliver a solution that would address these environmental challenges while maintaining operational continuity within a live care environment.
Engineering and Design Approach
Following a comprehensive site investigation, AE Smith identified that the HVAC system could not effectively manage humidity during cool and humid ambient conditions. A tailored de-humidification solution was developed, incorporating outside air pre-conditioning and integration with the existing system. The design was optimised to operate within strict electrical and spatial constraints, avoiding the need for major infrastructure upgrades.
System Integration and Innovation
The implemented solution included the installation of a purpose-built de-humidification system, enhanced by Bi-Polar Ionisation and UV Surface Sterilisation technologies. These additions significantly improved indoor air quality while ensuring efficient system performance despite the energy-intensive nature of dehumidification processes. Seamless integration with the existing HVAC infrastructure enabled effective delivery without disruption to residents or facility operations.
Performance and Outcomes
The system achieved an average relative humidity of approximately 64%, exceeding the original design target of 75%. The integration of the Syncromesh smart platform enabled real-time monitoring of PM2.5, PM10, and CO₂ levels, with results consistently below contamination thresholds. This delivered a measurable improvement in environmental conditions, creating a healthier, safer, and more comfortable setting for residents and staff while establishing a benchmark for future Carinity facilities.
