Accolade Winery – Efficiency is the Key

Accolade winery is the biggest winery in Australia, able to crush 200,000 tonnes of grapes a year.

Temperzone's High Energy Efficiency and exceptional controllability are our use of Advanced Variable Technologies.

You may not recognise the Accolade name even though it is now the 5th biggest wine producer globally and has a portfolio of 51 premium wine brands from Australia, New Zealand, North America and Europe.

The Accolade story starts with famous Australian wine producer Hardys Wines in South Australia and now includes well known Australian labels like Grant Burge, Banrock Station, Berri Estates, Tatachilla, St Halletts and Houghtons

Included in the big statistics are the 11 Temperzone OPA1370 Rooftop package units and 3 of Temperzone’s flagship OPA 2100 Eco Ultra Rooftop Package units on the roof of the new plant. Together these units deliver over 2000 kW of air conditioning.

Temperzone was installed based on energy efficiency which was a key requirement for this project.

After initially having Temperzone Eco and Eco Ultra units specified for the project, another company, with completely different technology approached the building owner directly with a proposal claiming superior energy efficiency.

To resolve the fairly technical energy efficiency analysis of the two proposals an independent consultant was brought in. The consultant’s conclusion was that the Temperzone units provided significantly better energy efficiency across the entire duty cycle.

The conclusion was that Temperzone equipment provided the biggest energy efficiency dividend as well as an exceptional level of control.

The key to Temperzone’s High Energy Efficiency and exceptional controllability are our use of Advanced Variable Technologies.

The Warriewood Cinemas replacement project in April 2020 had some slightly unusual application issues. A little lateral thinking, a great product range and the ability to manufacture locally in the middle of a pandemic, produced a successful solution.

OPA ECO Series

Temperzone’s ECO Series of Rooftop Package Units continues to evolve as some of the most energy efficient air conditioning units in the market. With unit capacities ranging from 11.6kW to 193kW Temperzone Eco Rooftop Package Units are used in a huge range of applications from shopping centres to food manufacturing plants to pubs and clubs, schools and office buildings.


Temperzone’s OPA2100 ECO ULTRA has been awarded the CIBSE Highly Commended award for the Product or Innovation of the Year - Thermal Comfort category. The Chartered Institution of Building Services Engineers (CIBSE) Building Performance Awards recognise the people, products and projects that demonstrate engineering excellence in the built environment. The awards are open to organisations, both in the UK and internationally

St Columba College

Building Energy Efficiency is a hot topic at the moment. If you ask an architect about energy efficiency, they will say it is mostly to do with design and construction. A controls person will tell you that real energy efficiency requires a state of the art BMS system. The air conditioning engineer will of course, tell you it’s all about the air conditioning design. The St Columba School library project is a great example of how a holistic approach that integrates design, construction, BMS and air conditioning technology can produce truly exceptional energy efficiency results.


The best way to describe this unusual project is 'Super flexible and controllable'. Temperzone OPA-ECO units meet very clever Modbus programming and solves an almost impossible air conditioning problem. And, oh yes, fit the budget too!


In January this year the “Energy Rating” organisation announced that from April 2019 a standardised method of calculating the Seasonal Energy Efficiency Ratio (SEER) will come into play.

Introducing the New OPA 2100 ECO Ultra Rooftop Package Unit

The new OPA 2100 ECO Ultra rooftop package unit is the flagship of Temperzone’s new ECO Ultra range. It’s a 200 kW rooftop package unit with 4 inverter compressors plus a patented humidity control system that makes this unit absolutely unique. Eco ULTRA is a revolutionary climate control solution for spaces where temperature and humidity regulation is critical.
