Completed Project

Arthur Boyd Art Gallery, Bundanoon

Architect: Kerstin Thompson Architects

Builder: ADCO Constructions

Location: Bundanoon, New South Wales

System: Geothermal Exchange Closed-Loop Vertical Ground Heat Exchanger

Capacity: 220kW

Project Brief/Scope:

  • Efficient and environmentally-friendly heating, cooling and dehumidification
  • Resilient ground-source heat pumps
  • Entirely sub-grade system in accordance with the Gallery’s fire-and-flood resistant ethos
  • Critical controlled heating, cooling and dehumidification to Art Museum, and Bridge

CWL Group assisted in providing an environmentally-friendly and sustainable ground-source heating, cooling, and dehumidification system following Bundanon’s sustainability goals. The mechanics of the system also needed to be “disaster-proof” (bushfire and flood-resistant), post the Black Summer fires that had nearly destroyed the Arthur Boyd collection in 2019-2020.

The key to this fire and floor resilient solution is the geothermal exchange system’s vertical ground heat exchanger, which consists of a network of specialised high-density polyethylene pipes that vary in depth from 600mm to 100m beneath the surface. Unlike conventional surface-mounted cooling-tower alternatives that would typically be utilised, this vertical-ground heat exchanger has a 200-year life expectancy and is completely maintenance-free.

In designing and installing a closed-loop vertical ground heat exchanger for a ground-source system, CWL Group has left the grounds surrounding the Art Museum and Bridge unimpeded and free for visitors to walk freely. Now open to the public, the owners are enjoying energy-efficient zero-carbon heating, cooling, and dehumidification across the property, year-round.

We engaged CWL for the geothermal exchange and HVAC works on our unique project in Bellevue Hill and were selected based on pricing and their previous experience. It turned out to be the best choice in subcontractors we made for the whole project. Their professionalism, work ethic, expertise and willing to help wherever needed made a highly complex services installation that much easier, and more efficient than expected. I’d like to personally thank James and the site team who put the extra effort in at all times to get our project over the line with remarkable results. Highly recommended Subcontractors and mechanical consultants.

I want to thank CWL Group for the outstanding work in installing our hydronic heating system. I have worked with many plumbers over the years and I have never seen such a high standard of workmanship. They came in on time and on budget. I cannot recommend the team from CWL Group highly enough.
