Dunedin International Airport

Atmos was pleased to work with project managers Arrow International on the two-year redevelopment project at Dunedin's award-winning international airport complex.

The $2 million dollar mechanical services contract included a 500kw heat pump system that recovers heat from bore water taken from deep under the Taieri Plain. In summer this system works in reverse using the bore water as a heat sink for the main air conditioning system.

The project included the installation of reticulation pipework for chilled and heating water throughout the building serving fan coils and air handling units.

The main arrival hall is served by a positive displacement system supplying conditioned air to the space via perforated stainless steel diffusers at a low level. These allow high air volumes to be used with minimal air movement and drafts. They look good and are a distinctive feature of the building.

Three separate plantrooms, six air handling units, close control air conditioning for the IT room, supply and extract systems for the main kitchen area, and a myriad of other HVAC systems all go together to form a significant engineering achievement for the region.

Completed on budget and on time, Atmos is proud to have been involved in this project.
