A shoutout to HVAC&R technicians
Let’s take a moment to acknowledge and thank the HVAC&R technicians for their hard work and dedication to keeping our environments comfortable and healthy
They play a crucial role in ensuring our homes and workplaces remain comfortable throughout the year. Their work involves installing, maintaining and repairing heating, cooling and ventilation systems essential for indoor climate control and air quality.
There are no specific requirements to become a HVAC&R technician as you gain skills on the job. However, many employers prefer to hire refrigeration/air-conditioning technicians who have or are working towards a qualification.
To become a fully qualified refrigeration/air-conditioning technician you need to complete an apprenticeship and gain a New Zealand Certificate in Refrigeration and Air Conditioning – Trade (level 4).
HVAC fun facts
• The first air conditioner was built on July 17, 1902, by Willis Haviland Carrier to control humidity in a printing plant and allow ink to dry in hot conditions. He was named one of TIME magazine’s ‘100 Most Influential People of the 20th Century’ in 1998.
• The first automotive air-conditioned car was the 1939 Packard. The AC unit took up most of the vehicle’s trunk space.
• The world’s largest HVAC system is in the Holy Mosque in Makkah (Mecca), Saudi Arabia. To cool a space that sees up to 1 million visitors a month in a climate where temperatures frequently top 100 degrees, the system has 135,000 tonnes of refrigeration capacity and uses R134A refrigerant.
Servicing and maintenance
We recommend using a CCCANZ member company to service and maintain your air-conditioning systems.
What role does
HVAC&R
play in preservation?
Senior Conservator at the Alexander Turnbull Library, Vesna Živković, shares how documentary heritage is kept from degradation
Buildings such as the National Library of New Zealand Te Puna Mātauranga o Aotearoa are time capsules, preserving documentary heritage such as manuscripts, books, paper documents, newspapers, maps, prints, drawings, audio and videos, and other items from previous decades and centuries. IRHACE even has historical information stored with the National Library including minute books, proceedings of IRHACE conferences and symposiums, as well as Journals dating back to 1933.
To keep these items from degradation, control of environmental factors is important. Air conditioning has been used to achieve this since the Second World War when The National Gallery in Britain stored paintings at 50 per cent relative humidity and 20ºC in a subway for safekeeping.
The IRHACE collection at the National Library includes records relating to the organisations from which current institute is formed, such as IRACE minutes (1933-83), IHVE minutes (1977-86), a members list from the 1950s-80s, collection copies of the periodical Thermonews, and more. Materials were donated by IRHACE in November 2011.
“In the National Library, we currently have more than 7,000 square meters of collection stores with different collections, varying from newspapers, photographic negatives, books and manuscripts, to audiovisual materials, and each of these stores has its own HVAC plant,” says Vesna Živković, Senior Conservator at the Alexander Turnbull Library, National Library of New Zealand.
“When it comes to library and archives materials, they are mostly paper-based objects inherently sensitive to incorrect levels of temperature and relative humidity. The rule is the lower the temperature, the longer the life expectancy of those items. For example, newspapers are printed on acidic paper and are not intended to last, so if you keep them in room conditions, they will yellow, become brittle and disintegrate.”
Research shows that dropping the temperature by five degrees can double the life of chemically unstable material such as this.
“Thus, cooler temperatures are preferred for collections with long-term value. The guidelines for extended-term storage conditions specify different temperature ranges for the storage of mixed media collections based on their sensitivity and chemical stability, including cold conditions between 0ºC and 8ºC, and cool conditions, set between 8ºC–16ºC. Both Archives New Zealand and the National Library have these conditions,” says Vesna. “The National Library was purpose-built in 1985, which is rare for cultural heritage buildings, and was the first government building in New Zealand to have air conditioning installed.”
Lowering relative humidity also contributes significantly to extending the life expectancy of documentary heritage, says Vesna.
Conditions for the preservation of material in the library include:
• A cold room at 2ºC with a freezer at -25ºC. “The freezer is intended for long-term preservation but mostly for treatment of pests and also for freezing the wet library material in case of flooding. This is an option when there is mass damage to material and you cannot treat it immediately,” says Vesna.
• A cold store at 2ºC at 30 per cent relative humidity, intended for photographic negatives including nitrate and acetate negatives. This climate is equally important for the preservation of unstable (colour) negatives and transparencies.
• Cool stores ranging from 13ºC, 40 per cent relative humidity to 18ºC, 45 per cent relative humidity.
Changes to the National Library’s storeroom conditions
Previously, the National Library aimed to achieve a flatline of both relative humidity and temperature – which it succeeded in – as this was considered imperative and optimum conditions for the preservation of objects in cultural heritage institutions.
“However, current research on material deterioration and discussions on environmental sustainability have prompted the question of whether these tight environmental controls and maintaining specific set points and narrow ranges are necessary.
Furthermore, in a library or archives facility where you have mass of hygroscopic materials, the impact of fluctuating relative humidity would be slow and minimal,” says Vesna.
“What we are looking at now is broadening the environmental parameters. Rather than having, for example, 13ºC plus or minus -2ºC and 40 per cent plus or minus -10 per cent relative humidity, we are looking into allowing seasonal variations and we are in the process of reviewing our requirements for conditions in collections stores based on our current body of knowledge.”
Vesna cites ASHRAE Chapter 24, intended for museums,
galleries, libraries and archives, and its advice on options for allowing seasonal and gradual variations depending on climate and conditions in the building, as well as sensitivity of materials.
Mechanical system shutdown tests have also been completed, focusing on two stores with an intention to explore shutdowns as an energy-saving option to be implemented in the library without compromising the preservation of collections. One is highly insulated and tests showed it’s possible to shut down the HVAC system for up to 10 hours overnight without impact on the system or conditions in the store. Shutting the system down over the day has also been tested to see the benefits.
“Another test we conducted was in a storeroom with windows. This test confirmed the high level of air leakage and we are now looking at how we can manage that to enable both an increase in the store’s resilience and proceeding with mechanical system shutdowns,” says Vesna.
“While the National Library building has very well-maintained climate conditions for the collections, there are options to manage the HVAC systems more sustainably in terms of energy efficiency, decarbonisation and cost reduction.”
In 2021, the National Library established the Alexander Turnbull Library (ATL) Environmental Management Team (EMT) with the aim to make recommendations for energy savings and sustainable practices, while upholding the long-term preservation of collection materials. Utility bill analysis indicated that the energy used to condition ATL collection storage areas represented around 80 per cent of the total energy consumption for the National Library building.
The ATL EMT conducted a series of controlled mechanical system shutdowns to confirm the viability of shutdowns as an energy-saving strategy and to inform on the performance of the selected ATL collection stores in terms of conditions for preservation of collections and system operations. The results of the tests and subsequent discussions within the team confirmed that no significant changes in conditions that would present risks to collections, health and safety, or impact on system capability were observed during any of the plant shutdowns. It was also noted that there are further options for energy savings within the HVAC&R systems at the level of ventilation, fresh air intake and dehumidification as they are considered the biggest consumers of energy in the National Library building.
At the beginning of 2024, the National Library initiated an implementation of a series of sustainability initiatives through the Property Capital Forward Works Project (PCFWP). This includes planned mechanical systems shutdowns, building tuning, replacement of supply air fans and enabling the implementation of DCV (demand controlled ventilation).

Global Skills Challenge wraps up across the ditch
New Zealand brings home a medal ahead of the international competition later this year
Designed to simulate the conditions of the international competition and allow competitors, experts and other support team members the opportunity to meet ahead of Lyon 2024, the 2024 Global Skills Challenge in Melbourne attracted plenty of camaraderie.
Over the four-day event, 138 competitors from 17 countries put their skills to the test across 29 categories. For the refrigeration, heating and air conditioning skill, five countries were competing – Australia, Austria, Brazil, Hong Kong and New Zealand – with our own Jack Butler bringing home a silver medal, with gold going to Austria and third place going to Australia.
Medals were presented at a formal closing ceremony which was attended by all competitors and their official
delegations, senior vocational education and training (VET) and government representatives, WSA partners and guest of honour, the Ambassador of France to Australia, Pierre-André Imbert.
WorldSkills Australia CEO, Trevor Schwenke, says the event was a resounding success: “Touring the event sites, the spirit of competition was only outmatched by the sense of camaraderie and collaboration between nations. Seeing officials and competitors mingling, discussing how they approach their skill back home is what it’s all about.”
Stay tuned for results from the 47th WorldSkills Competition in September.
Keeping the dairy industry moving
A small Waikato-based company shares their experience in providing HVAC&R solutions to the dairy industry, the challenges faced in this area today and what needs to change
No one needs to be told that dairy means big business in New Zealand. In the year to March 2023, the sector contributed over $11.3 billion to the country’s GDP.
Something that is often forgotten, though, is the essential role HVAC&R plays in the success of the industry: the quicker milk is cooled after milking, the better the quality when it is collected from the farm.
The Ministry for Primary Industries New Zealand Code of Practice for the design and operation of Farm Dairies has milk cooling standards that state that raw milk must:
a. be cooled to 10°C or below within four hours of the commencement of milking; and b. be cooled to 6°C or below within the sooner of: i. six hours from the commencement of milking, or ii. two hours from the completion of milking; and c. be held at or below 6°C without freezing until collection or the next milking; and d. must not exceed 10°C during subsequent milkings.
However, with milk cooling accounting for about 30 per cent of the total energy costs of operating a dairy farm, paired with climate targets, farmers also need systems that are cost- and energy-efficient.
Based in Te Awamutu, King Cooling & Heat Pumps is focused on helping its local customers achieve this.
“With what’s going on in the industry and with climate targets, I had to look at other options of what was out there and what would be best moving forward for our customers’ efficiency,” says Bradford Johanson, director at King Cooling and Heat Pumps.
“We had to change the game from what was out there with refrigerant at the moment and the carbon tax charges that are attached to them. We found units being built in New Zealand using Temperzone units from a small company in Napier using R32 refrigerant with compressors on them instead of fixed speed, which means greater efficiencies again.”
While some companies are still offering R410A systems which are being phased out, says Brad, the R32 systems are providing King Cooling and Heap Pump customers with a viable, more efficient solution that will last beyond the phase-out of high global warming potential (GWP) refrigerants.
“We thought it was our responsibility to offer this to our clients,” he says. “Some companies are offsetting the carbon that they’re using instead of minimising the carbon that they’re using. Is this helping stop climate change? Planting forests is a good thing that should be done on a value system; it isn’t targeting the cause.
“There are two sides at work. We’ve got to look at the climate side of it and how that affects things. But we’ve also got to look at the efficiencies of the systems we put in because that affects the climate as well with the power usage going into them.”
Advice for the industry
Moving forward, Brad says there also needs to be more focus on the maintenance of HVAC&R being used in the dairy industry across New Zealand, paired with the right training to provide customers with the right information.
“We need to be really proactive on refrigerant leaks and more rigid on maintenance to make sure there are no ongoing problems and that equipment is being upgraded when it needs. If technicians aren’t trained properly and haven’t got the skills or the knowledge, they can’t give the client good advice – not every farmer knows, they rely on us.
“As an industry, we have to say what direction is needed.”

Winning bids and government contracts with compelling case studies and evidence-based claims
How can you leverage the power of case studies to win tenders?
In the HVAC&R industry, securing tenders can be the key to unlocking new projects and growing your business across New Zealand. However, with numerous qualified contractors vying for the same opportunities, how can you make your bid stand out from the rest? One of the answers lies in the power of storytelling – specifically, through compelling case studies and evidence-based claims.
Case studies: showcasing your expertise
Think of a case study as a mini-success story that highlights your company’s capabilities.
It’s your chance to showcase a past project where you excelled, demonstrating your problem-solving skills, adaptability and commitment to quality.
Here’s what a strong HVAC&R-specific case study should encompass:
• What made you different? Don’t just list generic services. Focus on what set your approach apart. Did you implement a unique cooling system design to meet specific energy efficiency goals? Perhaps you devised an innovative solution to overcome a challenging building layout. Showcase your ability to adapt and think outside the box.
• Conquering challenges: Every project has its hurdles. Did you encounter unforeseen logistical issues or unexpected technical difficulties? Detail how you tackled these challenges head-on. Highlight your team’s resourcefulness and ability to find creative solutions under pressure.
• Safety first: In the HVAC&R industry, safety is paramount. Demonstrate your commitment to a safe work environment by outlining your safety protocols and reporting performance. Mention any specific safety measures implemented on the project and showcase your team’s zero-incident record (if applicable).
• Stakeholder management and client communication: Successful project completion hinges on effective communication. Explain how you managed communication with the client throughout the project. Did you establish regular progress reports or client briefings? Highlight your ability to build rapport and manage stakeholder expectations.
• Innovation and methodology: Did you employ cutting-edge technology or develop a unique methodology to complete the project? Detailing innovative approaches showcases your commitment to staying ahead of the curve and your ability to apply creative solutions for optimal results.
Evidence is king: back up your claims so the reader takes you seriously
A compelling case study is just one piece of the puzzle. To truly elevate your bid, evidence is crucial. Here’s how to strengthen your claims with verifiable proof:
• Testimonials: Positive feedback from satisfied clients speaks volumes. Include quotes or testimonials from past project managers or building owners.
• Visual storytelling: Pictures are worth a thousand words. Include high-quality images of completed projects showcasing the scope of your work and the finished product.
• Community support: Highlight your commitment to the local community by including letters from recruitment agencies confirming your use of local labour or thank you notes from community organisations for your involvement in local projects.
• Supporting letters: For specialised projects, consider including letters from material suppliers or equipment manufacturers verifying your expertise in using their products.
The winning formula: combining case studies and evidence
By weaving compelling case studies with verifiable evidence, you create a powerful narrative that showcases your company’s capabilities and builds trust with potential clients. Here’s how to integrate them effectively:
• Align case studies to project needs: Don’t just throw in generic case studies. Choose examples that directly address the specific requirements outlined in the tender. This demonstrates your understanding of the project and your ability to deliver similar results.
• Quantify your success: Numbers add impact. Quantify the positive outcomes of your past projects. Did your innovative cooling system design result in a measurable reduction in energy consumption? Mention the percentage decrease to showcase your focus on efficiency and cost savings.
• Evidence for every claim: Don’t leave any statements unsupported. Back up every claim made in your case study with relevant evidence, such as testimonials or pictures. This builds trust and credibility with the evaluator.
The power of proof
In today’s competitive HVAC market, a well-written bid with compelling case studies and evidence-based claims can be the deciding factor. By showcasing your past successes and providing verifiable proof of your capabilities, you can demonstrate your commitment to quality, innovation and client satisfaction.
So, invest the time to craft powerful case studies, gather supporting evidence, and watch your bids rise above the rest. In the world of tenders, proof is the key to securing your next big project.

Represent the bulk of New Zealand’s HVAC&R industry, HVAC&R Centre’s submission is specific to the global warming impact of refrigerant GHG emissions, including but not limited to synthetic refrigerants (F-gases), as they relate to the Commission’s Draft advice on Aotearoa New Zealand’s fourth emissions budget
In summary
We have not submitted to the Commission’s 2024 review of the 2050 emissions target because we believe that any estimate of refrigerant GHG emissions in 2050 is highly sensitive to policy choices made in this decade. To quote the Commission’s consultation document for the 2024 review of the 2050 emissions target:
For any target to be effective, it needs to be relevant, achievable and timely. Over time, circumstances can change which affect a target’s impact and influence.
However, the Commission when considering the 2050 emissions target should consider the matters we have raised in this submission.
Unfortunately, the policy approach that has been taken by MfE with respect to managing the global warming impact of refrigerants, and by extension certain assumptions made by the Climate Change Commission, fail to address reality, this being despite the previous submissions our organisations have made.
Accordingly, we do not consider that the Commission’s target for annual F-gas emissions of 0.6 MtCO2e in the fourth emission budget period is unachievable unless there is a major policy rethink relating to how refrigerant GHG emissions are managed.
In our opinion the Emission Reduction Plan’s (ERP) Baseline projected emissions estimate of circa 1.2 MtCO2e (refer ERP Chapter 12 Fig 16.2 below) by the end of the fourth emission budget period would likely be a best-case outcome.
The previous government’s Priority Waste Product policy had the unintended consequence of continuing the historical focus on end-of-life F-gas recovery and destruction, the following realities either being ignored or not being given due consideration:
F-gases (direct fugitive Scope 1 GHG emissions)
1. The impact of F-gases on global warming and the opportunity to mitigate their impact is greater than is generally understood!
2. The inclusion of F-gases as a priority waste product under the previous government’s Priority Waste Product
policy was poorly conceived and managed. In particular, the co-design for the regulated Product Stewardship Scheme (PSS) had a predetermined outcome whereby the existing voluntary Refrigerant Recovery (Recovery) PSS for synthetic refrigerants, now calling itself Cool-Safe, would morph into the regulated PSS to continue with its sole focus on F-gas recovery and destruction.
3. Historically very little F-gas has been recovered at end-of-life, the bulk of F-gases end up being vented to the atmosphere from operating systems, principally due to ongoing leakage over the system’s life.
4. The fact that the bulk of hydrofluorocarbons (HFCs) are vented to the atmosphere, have high GWPs and relatively short atmospheric lives, means the critical need is to mitigate their impact on global warming during the current decade when the world most needs to respond to global warming.
5. There is a disconnect between what the Kigali Amendment’s (Kigali) phase-down of bulk HFC imports will achieve in terms of the mitigation of F-gas GHG emissions and the overhanging emissions risk of the F-gas refrigerant bank.
F-gases (indirect Scope 2 & 3 GHG emissions)
6. All refrigerant types cause GHG emissions, not just the F-gases, the historical focus on end-of-life recovery and destruction of F-gases has ignored the opportunity to mitigate the indirect Scope 2 and 3 refrigerant GHG emissions. In particular, energy efficiency should be a primary focus for any scheme seeking to mitigate Scope 3 refrigerant GHG emissions.
The lack of supply chain visibility
7. The fundamental problem facing refrigerant management is the lack of visibility through the supply chain, there being no visibility at the operating system level, you can’t effectively manage what you can’t measure! The lack of quality data is reflected in estimates of refrigerant GHG emissions having high degrees of uncertainty.
Each of the above matters are addressed in detail in the full submission. Read online here.
HVAC&R safety reminder
A steel ductwork collapse in the US is a reminder of the need for adequate training and safety in the industry
Thankfully this is not a scene from New Zealand. However, the falling of a large portion of steel ductwork in Aurora, Colorado, has been an important reminder of what can go wrong if safety advice is neglected.
At the time of the collapse, the lawsuit that was ultimately filed claims the ductwork improperly contained a significant amount of water, showed significant rust corrosion of the internal surface, and that the cable suspension system was grossly insufficient to support the ductwork.
“This case arises from the collapse of air exchange ductwork in the indoor pool at the Gaylord Rockies Resort and Convention Centre. Due to poor design, poor construction and poor maintenance, several hundred feet of four-foot diameter steel ductwork –weighing thousands of pounds – fell 35 feet to the concrete floor below, crashing into several people,” the lawsuit says.
Falling into a pool with between 50 and 100 people in it, the ductwork injured six people.
“The ductwork struck John Markiewicz in the head, driving his body into the concrete floor, shattering his skull, causing multiple rib fractures, a bruised heart, and a traumatic brain injury. He was unconscious when paramedics arrived and hip injuries are so severe, it is a miracle he is still alive today.”
The same is said for a 13-year-old girl, who, as she tried to escape, had the ductwork knock her out of a hot tub. This resulted in the ductwork snapping her pelvis in half, shattering her hip, and causing so much internal hemorrhaging that without blood infusions, emergency surgery and the efforts of emergency medical personnel, she would have bled to death.
“Tonnes of steel ductwork should not fall from the ceiling, and these life-changing injuries should never have happened,” the lawsuit summises.
What to know: Importing and exporting hydrofluorocarbon gases (HFCs)
With the risks involved, permits are required to import or export bulk HFC gases into or out of New Zealand
What’s classified as ‘bulk HFC gases’?
Under law, according to the Environmental Protection Authority, ‘bulk HFC’ means new or recycled HFC gas in an unprocessed form – alone or in a mixture – in a container used for gas transport or storage. However, HFCs in manufactured products, such as car airconditioning systems or fire extinguishers, do not need an import or export permit.
Bulk HFC importing limits
There are also restrictions on how much HFC gas can be imported into the country. This is to encourage the move to alternative gases or HFCs with lower global warming potential (GWP).
“To reduce our reliance on ozone-depleting gases, the man-made gases collectively known as hydrofluorocarbons (HFCs) were developed. They are also known as one of the fluorinated gases, ‘F-gases’, and individually under their chemical names (prefixed by ‘HFC-’, ‘R-’, and sometimes under the Freon brand name).
“Although HFCs have a smaller impact on the ozone layer, they are potent greenhouse gases which warm the atmosphere and contribute to climate change. Reducing levels of HFCs will avoid up to 0.5 degrees of global warming by 2100. So in 2016, the Montreal Protocol was amended (the Kigali Amendment) to ensure that industrialised and developing member countries reduce their HFC production and consumption over time.”
Types of permits and when to apply
The type of import permit, and when you need to apply, depends on the origin of the HFC (new or recycled).

What is an NZBN and what’s its role in
business?
The NZBN is a unique identifier for your business.
The New Zealand Business Number (NZBN) is a globally unique identifier, available to every Kiwi business. Whether you’re self-employed or a major corporation, there’s an NZBN for you.
Your NZBN makes doing business faster and easier because it links to your core business information (known as Primary Business Data). This includes things such as your trading name, phone number or email.
That means anyone you do business or interact with (such as suppliers or customers) can easily, quickly and digitally access all the details they need about your business in order to work with you. You won’t have to keep repeating this information or updating it in multiple places. With an NZBN your business becomes part of a single, searchable register for all Kiwi businesses.
The New Zealand Business Number (NZBN) Act came into effect in 2016, enabling all businesses to be allocated or register for an NZBN. This includes government agencies who are working to implement the NZBN into their systems and processes. The flow-on effect will be that agencies can get core business information from the NZBN Register, eliminating the need for businesses to provide and update it.
