Beyond the Surface: How Geothermal Is Shaping Smarter Design

Yesterday at Goldfish & Bay, our latest LUNCH &LEARN session spotlighted geothermal technology, a system that’s practical, sustainable, and fast gaining traction in the Australian market. James O'Neill from RHCS led the session, unpacking how ground-source heating and cooling is being integrated into our upcoming Oceania Manly project. Beyond the technical workings, the discussion explored how this system reshapes thinking around building performance, operational efficiency, and long-term carbon impact.

For our mechanical team, the session offered valuable insight into real-world application: how geothermal can support pool heating, underfloor distribution, ventilation, and domestic hot water supply. With stable subsurface temperatures, these systems maintain output without the seasonal inefficiencies often seen in air-sourced rooftop units.

One of the most compelling aspects? The removal of rooftop HVAC infrastructure—freeing up space for additional apartments, rooftop gardens, or shared amenities. It’s a smart move with environmental and commercial upside, aligning with rising expectations around sustainable building outcomes.

Goldfish & Bay is proud to be delivering mechanical engineering design for Oceania Manly, and even prouder to be part of a project that treats sustainability as a priority, not a feature.

Thanks again to James O'Neill and the RHCS team for an insightful session.

We welcome opportunities to collaborate with suppliers and specialists through knowledge-sharing sessions that inform our work. Innovation is driven by real-world conversations, technical insight, and practical decisions made across every project. 🧡
