Architect: Wallce E. Cunningham, Inc (USA)
Builder: BUILT
System: Integrated heating and cooling using centralised 6 Pipe Ground Source Heat Pump
Capacity: 97kW

Project brief/scope:

• Hydronic underfloor heating
• Space Heating and cooling via concealed fan coil units
• Pool/spa heating to design temp of 40deg C
• Cold plunge therapy (ice bath) conditioning to 7 deg C

CWL Group was engaged to assist in resolving project design constraints on this challenging site for the mechanical / HVAC services. The key problems that needed to be overcome were:

• Limited air delivery paths for heating and cooling due to the bespoke design brief
• Space limitations for plant and equipment
• Council sound level limitations to comply at the property boundary

CWL Group delivered a full turnkey solution for the project brief while overcoming the design constraints using, in house engineering capabilities to design and install the geothermal exchange system. This project used a vertical ground heat exchanger, drilled and installed beneath the structure with a single commercial geo-specific 6 pipe chiller providing simultaneous heating and cooling. The air conditioning system was delivered through whisper-quiet 4 pipe hydronic fan coil units designed and installed to deliver the air through our in house custom designed and manufactured APL ducting system with a combination of covert slots and custom made featured brass grilles. Minor details such as controls and remote thermostats were discreetly installed within custom enclosures becoming virtually invisible. The 40Lk pool doubles as a therapy spa adjustable to 40deg C while the adjacent cold plunge pool benefits from the spa heat rejection capable of reaching 4 degrees C.
