Ormiston Rise, QLD
Project Description
Located in Ormiston, Brisbane, this multi-stage retirement living development by Tranquil Retirement Group was designed to provide a calm and comfortable residential environment within a growing coastal community. The project comprises of private residential apartments requiring reliable, year-round climate control suited to the region’s warm and humid conditions. Mechanical contractor Effective Airconditioning Services worked closely with Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) to deliver a quiet, easy-to-use air conditioning solution that supports resident comfort and independence, while maintaining consistency across the development’s staged construction.
Project Requirements & Challenges
Delivering reliable climate control in Brisbane’s warm, humid coastal environment presented several design and performance challenges. The system needed to maintain stable indoor temperatures while operating quietly to preserve the peaceful atmosphere expected in a retirement living community. Ease of use was also essential, ensuring residents could comfortably manage their indoor environment without unnecessary complexity. From a design perspective, outdoor condensers were required to be located away from apartment balconies to maintain visual appeal and minimise noise, requiring careful planning around equipment placement and pipe runs. As the project was delivered in multiple stages, the HVAC solution also needed to provide consistent performance while allowing flexibility throughout the development process.
MHIAA’s Solution
To meet the project’s performance, usability and design requirements, Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) supplied 63 ducted air conditioning systems to residential apartments throughout the development. MHIAA worked closely with the appointed mechanical contractor, Effective Airconditioning Services, during the design and selection phase to ensure the solution aligned with the building layout, performance expectations and the specific requirements of a retirement living environment. Through this collaboration, the project incorporated a combination of FDUM Series ducted indoor units in 2.8kW and 3.6kW capacities, alongside larger FDU Series systems ranging from 7.1kW to 11.2kW, with configurations carefully selected to suit the scale and thermal load of each apartment.
MHIAA ducted systems were chosen to deliver quiet, consistent heating and cooling while maintaining a clean and unobtrusive interior aesthetic. Each apartment was fitted with in-ceiling ductwork and discreet ceiling vents, ensuring even air distribution without visual clutter or disruption to residents’ living spaces. EcoTouch remote controllers were installed to provide a simple and intuitive interface, allowing residents to easily manage their indoor comfort while maintaining precise temperature control suited to retirement living.
To preserve the tranquillity and visual appeal of private balconies, outdoor condensers were positioned away from apartment living areas, located on rooftops or within designated service zones. This approach required longer pipe runs, providing flexibility in equipment placement while maintaining reliable system performance. Compact single-fan condensers were used to support space efficiency, minimise operating noise and reduce power consumption – an important consideration in Brisbane’s warm, humid climate. Delivered as part of a multi-stage development, the solution required close coordination with the developer to ensure consistency across stages. Having successfully used MHIAA systems in earlier phases, the developer again selected MHIAA KX 1:1 ducted systems for Stage 2, reflecting strong confidence in the product’s performance, durability and long-term support.
