Custom HVAC Solution for Ballantynes Retail
A major redevelopment project for Christchurch department store Ballantynes was underway. Adding a five-level, 2,600m² building to replace space they lost in the Canterbury earthquakes.
The multimillion-dollar expansion was headed by Naylor Love in partnership with AECOM New Zealand Ltd (PQS/Project Management), Peddlethorp (Architect/Designer), Ruamoko Solutions (Engineer).
Completed in 2020 the redevelopment features two levels of premium retail space, one floor of office space, meeting rooms, staff amenities, stock processing space and delivery dock. Also, covered car parking and open-air car parking on the roof.
Action Taken
Project HVAC was chosen as a supplier of the central 4-pipe multifunctional chiller heat pumps and central heat recovery AHUs for this redevelopment. Required to provide central heating, cooling, heat recovery ventilation and air conditioning plants.
Each of high energy-efficient, lightweight and able to fit in a plant room of very limited space.
They supplied and commissioned:
- Clivet brand multifunctional 4-pipe chiller heat pump unit which prepares hot and chilled water for heating and air conditioning.
- This unit generates hot water free of charge by using the waste heat which would otherwise be rejected into the atmosphere when the building needs air conditioning.
- This also significantly reduces energy consumption and requires only half the plant room space which would normally be required for central cooling and heating plants for this type.
- Seven Clima HVAC heat recovery AHU were installed to provide fully automated, demand-driven ventilation and air conditioning to each occupied room. Simultaneously ensuring a comfortable room temperature all year round.
- These unique units can temper the supplied fresh air simply by recovering up to 90% of the heat extracted from the discharged stale air.
This results in a dramatic reduction in heating costs for the building and in turn, reduced CO2 emissions.
- Two insulated pressurised Clima HVAC buffer tanks for heating hot water and chilled water storage.
- Total volume of the air delivered and processed by 7 Project HVAC Clima HVAC Heat Recovery Air Handling Units (AHUs) supplied to the Ballantynes Retail Redevelopment project is above 100,000 m3/hr.
- Total heating and cooling capacity delivered to the building by project HVAC central plants is nearly 800 kW.
Heat recovery efficiency of the supplied AHUs is more than 80% thus ensuring that the large part of the energy required for heating of the building fresh air is recovered from the waste heat.
Project HVAC’s range of Clivet air-source chiller heat pumps and Clima HVAC AHU units are designed to a high standard and backed by the support of a highly trained technical team.
Results
The multifunctional 4 pipe chiller and heat recovery ventilation plants have been running without a single failure since their installation.
Project HVAC’s technical expertise is key to the seamless plant operation. Knowing its products and their manufacturers, Project HVAC offers optimal solutions across a broad range of applications.
The J Ballantyne & Co redevelopment was awarded the Retail category gold award at the NZ Commercial Project Awards 2021.
