In the February 2021 edition of AIRAH’s Ecolibrium magazine, Sean McGowan reports innovative high-performance HVAC system delivered by a highly collaborative team of A.G. Coombs and LCI consultants to meet rigorous fitout requirements while achieving ambitious sustainability targets.

• Unique hybrid Passive Chilled Beam and Low Temperature VAV system. This system significantly reduced ceiling head height requirements – enabling an additional floor to be added to the building!
• Advanced design featuring high efficiency chillers, hybrid cooler plant and EC plug fans to achieve a 5 Star + 15% NABERS Energy base building rating whilst catering for high outside air / high heat load tenancy requirements.
• Leading BIM techniques to optimise design for the very intensive fitout requirements and support state-of-the-art modular prefabrication and construction techniques.
• Leading-edge system instrumentation and chiller control to tune systems maintain efficiency.
• Combined return-air fan system serving multiple AHUs featuring sophisticated supply air fan control algorithm utilising real-time flow rates.
• Sophisticated integrated HVAC and smoke hazard management strategy for the very large centrepiece building atrium.

The sophistication of these systems represents a significant step forward for mechanical and HVAC services in Australia.
