Case Study: Geothermal Heating & Cooling for a Heritage Home in Kooyong, Australia

Project Overview

SóGeo collaborated with GT Drilling to implement a ground source heat pump system for a heritage-listed residence in Kooyong. Situated near the iconic tennis club, this historic home was undergoing a modern extension, requiring an energy-efficient heating and cooling solution that would seamlessly blend with its architectural heritage. By integrating a discreet geothermal system, SóGeo provided a sustainable alternative that enhances comfort while reducing energy consumption.

Scope and Execution

SóGeo designed and integrated the geothermal system, while GT Drilling executed multiple deep boreholes to facilitate efficient heat exchange. Despite restricted access and the need to preserve heritage features, the project was successfully completed within a short timeframe. Careful planning and execution ensured minimal disruption while delivering an advanced heating and cooling solution tailored to the property’s needs.

Smart System Design & Integration

Understanding the home’s structural and environmental requirements, SóGeo engineered a customised ground source heat pump system. The design accounted for key factors such as heat load, geological conditions, and strict noise regulations. To ensure longevity and reliability, high-quality piping materials were selected, and all major mechanical components were placed underground. This approach maintained the home’s historic charm without requiring unsightly outdoor equipment, aligning with heritage preservation guidelines.

Overcoming Challenges with Innovation

Preserving the visual integrity of a heritage-listed home posed unique challenges. By strategically placing the geothermal loops underground, SóGeo eliminated the need for bulky condensers or external plant units. This not only met aesthetic and heritage regulations but also significantly reduced operational noise, enhancing indoor comfort without compromising the home’s historic character.

Sustainable Solutions & Environmental Responsibility

As part of SóGeo’s commitment to eco-friendly HVAC technology, the project adhered to stringent environmental and heritage requirements. The geothermal system reduces reliance on conventional heating and cooling, lowering carbon emissions and energy usage. Additionally, responsible drilling practices minimised site waste and environmental impact, reinforcing SóGeo’s dedication to sustainable solutions across Australia.

Outcome & Long-Term Benefits

The installed geothermal system offers significant energy savings while ensuring year-round comfort. Homeowners benefit from reduced utility costs and a quiet, efficient heating and cooling solution that preserves the integrity of their heritage home. This project highlights SóGeo’s expertise in seamlessly integrating modern, sustainable HVAC solutions into historic properties, demonstrating the potential of geothermal technology across Australia’s residential sector.
