Havilah Apartments uses a combination of ducted air conditioning and VRF systems, allowing each apartment to benefit from efficient, zoned temperature control while maintaining overall system performance across the building.
VRF systems offer flexibility, energy efficiency, and zoning capabilities, making them well suited to multi-residential buildings where each apartment has different usage patterns and comfort requirements.
Zoning allows residents to control temperatures independently in different areas of their apartment, improving comfort while reducing unnecessary energy use.
A dedicated mechanical ventilation system was designed to support indoor air quality across all apartments, ensuring consistent airflow and compliance with Australian building standards.
Yes. VRF air conditioning systems are commonly used in Sydney residential developments due to their efficiency, quiet operation, and ability to perform well in varied apartment layouts and climates.
Absolutely. Similar HVAC designs can be adapted for apartment buildings, mixed-use developments, and high-end residential projects where performance, efficiency, and long-term reliability are priorities.
