Preface

At the end of the third paragraph, add the following sentence:

Appendix ZA has been added to provide information on the development of the climate files for Australia and New Zealand.

Appendix ZZ

ZZ2 Delete the text of Paragraph ZZ2 and replace with the following:

The following modifications are required for Australian/New Zealand conditions:

Table 1 In Column 1, for the low humidity and cyclic cooling test, delete ‘WB 16°C or lower’ and replace with ‘WB 13.9°C or lower’.

6.2 Third paragraph, delete the equation and replace with the following: For the ‘hot/humid’ zone, t0 = 21°C and t100 = 33°C

For the ‘mixed’ and ‘cold’ zones, t0 = 21°C and t100 = 35°C

6.3 1 Delete the first paragraph and replace with the following: Tables 3.1, 3.2 and 3.3 show the reference outdoor temperature bin

distributions for each climate zone.

2 After the third paragraph, add the following text: The calculation of Australian and New Zealand cooling and heating

seasonal performance factors is based on temperature bin distributions for three reference climate files. They are derived from the 2016 Nationwide House Energy Rating Scheme (NatHERS) climate files. These consist of a typical meteorological year (TMY) file compiled from raw Bureau of Meteorology climate data.

DEVELOPMENT OF THE AUSTRALIAN/NEW ZEALAND CLIMATE FILES

(Informative)

ZA1 HOT/HUMID ZONE FILES

The ‘hot/humid’ zone (see Figure ZA1) file is based on the 2016 NatHERS TMY(A) file for Rockhampton, Queensland. Rockhampton is situated on the Tropic of Capricorn and is located geographically and meteorologically between the milder climates of the heavily populated south-east of the zone and the sparsely populated northern tropical areas.

The cooling season for the hot/humid zone is considered to be from 1 October to 31 May and all hours during this period are tallied. Cooling condition temperatures that occur outside these months are not considered.

To account for the likelihood of a residential user turning on their unit in response to the outdoor temperature (tj), a percentage was applied to each bin’s total, as per Table ZA1. At milder temperatures, there is a reduced proportion of hours counted. The percentage increases with temperature, as hotter conditions increase the likelihood of cooling being used.

ZA2 MIXED ZONE FILES

The ‘mixed’ zone file (see Figure ZA1) is based on the 2016 NatHERS TMY(A) file for Richmond, New South Wales. The mixed zone covers a large population and represents areas where both very hot and very cold weather can be encountered. As heating performance at H2 is important for determining seasonal performance, it is desirable to have a representative location that has an adequate number of bin hours at lower temperatures for this performance to be demonstrated. Coastal locations tend to have milder overnight temperatures, so Richmond, which is slightly inland, allows the calculation of seasonal performance at both low and high temperatures.

The cooling season for the mixed zone is considered to be from 1 October to 30 April and all hours during this period are tallied. Cooling condition temperatures that occur outside these months are not considered.


ZA3 COLD ZONE FILES

The ‘cold’ zone file (see Figure ZA1) is based on the TMY(A) file for Canberra in the Australian Capital Territory. In addition to a high annual heating load, Canberra experiences many bin hours within the critical frosting temperature range. Locations closer to the coast, while still having a high annual heating load, will not adequately demonstrate seasonal energy consumption that reflects H2 performance. Canberra also has a sufficient number of cooling hours to allow meaningful cooling performance to be demonstrated. This is not the case for the colder, largely unpopulated alpine and sub-alpine regions or New Zealand.

AMDT No. 1



The cooling season for the cold zone is considered to be from 1 November to 31 March and all hours during this period are tallied. Cooling condition temperatures that occur outside these months are not considered.

PREPARATION OF JOINT AUSTRALIAN/NEW ZEALAND STANDARDS

Joint Australian/New Zealand Standards are prepared by a consensus process involving representatives nominated by organizations in both countries drawn from all major interests associated with the subject. Australian/New Zealand Standards may be derived from existing industry Standards, from established international Standards and practices or may be developed within a Standards Australia, Standards New Zealand or joint technical committee.

During the development process, Australian/New Zealand Standards are made available in draft form at all sales offices and through affiliated overseas bodies in order that all interests concerned with the application of a proposed Standard are given the opportunity to submit views on the requirements to be included.

The following interests are represented on the committee responsible for this draft Australian/ New Zealand Standard:

Airconditioning and Refrigeration Equipment Manufacturers Association of Australia

Australian Building Codes Board

Australian Industry Group

CHOICE

Clean Energy Regulator

Consumer Electronics Association of New Zealand

Consumer Electronics Suppliers Association

CSIRO

Department of the Environment and Energy

Electrical Compliance Testing Association

Energy Safe Victoria

Institute of Refrigeration Heating and AirConditioning Engineers of New Zealand

The University of New South Wales

Standards Australia

Standards Australia is an independent company, limited by guarantee, which prepares and publishes

most of the voluntary technical and commercial standards used in Australia. These standards are

developed through an open process of consultation and consensus, in which all interested parties are

invited to participate. Through a Memorandum of Understanding with the Commonwealth

government, Standards Australia is recognized as Australia’s peak national standards body.

Standards New Zealand

The first national Standards organization was created in New Zealand in 1932. The New Zealand

Standards Executive is established under the Standards and Accreditation Act 2015 and is the

national body responsible for the production of Standards.

Australian/New Zealand Standards

Under a Memorandum of Understanding between Standards Australia and Standards New Zealand,

Australian/New Zealand Standards are prepared by committees of experts from industry,

governments, consumers and other sectors. The requirements or recommendations contained

in published Standards are a consensus of the views of representative interests and also take

account of comments received from other sources. They reflect the latest scientific and industry

experience. Australian/New Zealand Standards are kept under continuous review after publication

and are updated regularly to take account of changing technology.

International Involvement

Standards Australia and Standards New Zealand are responsible for ensuring that the Australian

and New Zealand viewpoints are considered in the formulation of international Standards and that

the latest international experience is incorporated in national and Joint Standards. This role is vital

in assisting local industry to compete in international markets. Both organizations are the national

members of ISO (the International Organization for Standardization) and IEC (the International

Electrotechnical Commission).
