8 1 b. E3 Program & Small Fan Units This stakeholder workshop opens up discussion with government agencies and industry around possible policy options for improving the energy efficiency of small fan units – E3 is a regulatory program, so MEPS and labelling are included in the options considered 8

9 Draft strategy for Non-domestic Refrigeration – In From The Cold Report: In From the Cold - Strategies to Increase Energy Efficiency of Non- domestic Refrigeration in Australia and New Zealand recommends that: – Minimum energy performance standards (MEPS) are introduced for fan motors used in non-domestic refrigeration applications, with an output power rating of between 5 Watts and 2,000 Watts 9

10 European Union: energy efficiency regulations for fans EU regulations will place energy efficiency requirements on fans with motor input power 125W - 500kW, aimed at inefficient ventilation fans used in non-residential buildings. – First tier: from 1 January 2013 - targets least efficient 10% of the market – Second tier: from 1 January 2015 - targets least efficient 30% of the market More detail on the European Eco-design Directive in Product Profile: Non-domestic Fans 10

11 Current E3 Motor and Fan Work Streams 11 Small Fan Units Product Profile covers fan units with input power 5 W – <125 W. Small Fan Units Product Profile covers fan units with input power 5 W – <125 W. Electric Motors Product Profile MEPS currently cover three-phase electric motors with output power 0.73 kW to 185 kW This forthcoming paper considers increasing MEPS levels and extending MEPS to include motors of larger and smaller sizes Non-Domestic Fans Product Profile Covers fan-units with input power 125 W to 500 kW.

12 2. Introduction to Small Fan Workshop Product Profiles are discussion papers which consider options for driving improvements to the efficiency of certain products: – Market assessment – Efficiency of products currently sold – Local and international standards – Possible policy options to increase efficiency 12

13 3. Overview of Small Fan Product Profile Scope of Product Profile Market characteristics Energy consumption, energy efficiency improvement and GHG emissions Policy options Standards Regulatory considerations 13

14 Scope of the Product Profile Scope of Product Profile is motor-driven fan units with input power 5 to <125 W Fan unit = fan and motor combination also includes integral fan-motor assemblies which are constructed such that it is not possible to separate the fan blade from the motor without losing the function of the fan 14

15 Applications of Small Fans Some small fan units are a stand-alone product: fans for human comfort cooling extractor and extractor/heater combination fans Some small fan units are embedded in appliances: computers refrigerators freezers room heaters with a fan clothes dryers hair dryers dishwashers room air conditioners ovens microwaves rangehoods 15

16 Discussion Points – Scope of Small Fans 1 Input power range 5 to <125W – is this appropriate? 2 Input power versus output power for defining the scope for small fan units? 3 Efficiency of fan-motor assembly (fan unit) versus efficiency of fan as a stand-alone item. What should we focus on? 4 Should the scope cover all fan units in this size range or should it exclude some types of fan units? 5 Additional applications of small fan units not listed in the Profile? 6 Market breakdown by small fans by application – is data available on installed stock and annual sales? 7 Feedback on terminology used when discussing small fan unit 16

17 Types of Motors Driving Small Fans Motor TypeMotor Characteristics Shaded-pole, single-phase Common motor, cheap to purchase and reliable but very inefficient – 5 to 70 Watt output. Are type of AC single-phase induction motor. Has a low starting torque so best used for fans that are easy to start. External rotor fan assembly: single & three phase Another common type of motor used with small fans. Version of AC induction motor where rotor rotates around the stator. Rotor is integrated into the fan blade. Has improved efficiency. Permanent split capacitor Mainly used in residential aircons and household appliances. Usually more efficient than same size shaded pole motors, but often operate below full load. Electronically commutated Synchronous electric motor which uses permanent magnets which rotate around a static armature. Require speed controllers and these are often integrated into small units. High efficiency, low noise and long life. Universal Commonly used in hand tools, hair dryers, and vacuum cleaners. High starting torque, generally run at high speed and are noisy. Have short life and best suited to intermittent uses.

18 Discussion points – Types of Motors 8 Proportions of small fan units driven by each type of motor? 9 Market for small fan motors, broken down by application? 10 Cost differences between types of small fan motors? 18

22 Discussion points – Market Profile 12Australia market characteristics and trends for small fan units – existing stock – annual sales – industry sector breakdowns 13Estimated sales and stock numbers for: – Small fan units imported for integration into products, or as replacement parts – Small fan units imported as components already integrated into appliances – Small fan units manufactured within Australia/New Zealand 14 Main countries for importing small fan units 22

23 Barriers to Energy Efficiency Improvement Split incentives - the fan unit is often chosen by the appliance designer/manufacturer yet the energy bill is paid by the end- user. Information failures - the end-consumer is unlikely to take account of the energy efficiency of small fan units. Bounded rationality - incomplete consideration of the costs and benefits of efficient small fan unit technologies Discussion point: 15 Market failures affecting uptake of high efficiency small fan units?

26 Discussion points – Energy Consumption Greenhouse Emissions 16 Energy use and greenhouse gas emissions from existing stock of small fan units, including: - total stock by end-use applications and size - typical power consumption and annual operating hours of small fan units 26

27 Opportunities to Improve Efficiency Efficiency improvements for small fan units from improvements to: – Fan motor – Motor – fan coupling – Fan The different types of motors used to drive small fans have different efficiency characteristics Existing Motor Type Output (W)EfficiencyNew Motor Type (1-ph) EfficiencyAv.

28 Discussion Points – Efficiency Opportunity 17 What opportunities for improving energy efficiency of small fan units? 28

29 International Situation US Energy Star certification – Ventilating fans (2001) – Ceiling fans (2002) European Union – EuP Lot 30 study which includes small motors has just started – Have been considering regulating ventilation hoods

30 Possible Policy Options Mandatory minimum energy performance standards (MEPS) High efficiency performance standards (HEPS) Ban the least efficient types of motors that drive small fan units Labelling or certification schemes Training and education Codes of best practice, benchmarking programs 30

31 Discussion Points – Policy Options 18 Greatest potential for improvements in energy efficiency: - Focus on the motor, the fan, or both? 19 Suitability of different policy measures to achieve improvements in energy efficiency of small fan units: - potential for savings in economic costs, energy, and greenhouse gas emissions 31

32 Standards – Test Method AS ISO 5801 sets out methods for determining performance of industrial fans of all sizes and types, except those designed for air circulation (ceiling and table fans). It may be possible to apply this method to products in the 5 to <125 W size range. There is an Energy Star specification for ceiling fans - this suggests a test method exists for these products. 32

33 Standards – Efficiency Levels ISO 12759 sets out Fan Motor Efficiency Grade curves, which specify minimum required efficiency at best efficiency point and can be used as the basis for setting MEPS levels for fan units of input power 125 W to 500 kW. Introducing MEPS for small fan units in Aust and NZ would require developing efficiency level classifications for products below 125 W input power. 33

34 Discussion Points - Standards 20 Appropriate efficiency levels for small fan units? 21Testing facilities capable of AS ISO 5801, and appropriateness of this standard for small fans? 22 Other standards issues? 34

35 Regulatory Considerations If regulatory action was deemed appropriate - a consultation Regulatory Impact Statement (RIS) for small fan units would be released for consultation. MEPS regulations in the EU will be applied to the fan+motor combination. While this approach has some drawbacks, it would allow Aust and NZ to align - and EU is a major source of fan imports. It may be practical to introduce regulations for certain sectors (such as fan units used in non-domestic refrigeration) – although MEPS normally apply to generic equipment categories. 35

36 Regulatory Considerations Key challenges for regulating small fan units: 1. Most enter Australia and New Zealand as a part integrated into another product: - Potentially difficult to identify products which are subject to regulation, and to enforce compliance. 2. Many small fan units are components within a product that is already regulated for energy efficiency: - Regulatory options include regulating the small fan unit separately, or increasing the MEPS levels for the whole appliance to drive improvements in fan efficiency. 36

37 Discussion points – Regulatory Considerations 23 Regulations targeting the fan only vs regulating the fan-motor combination? 24 Voluntary/non-regulatory approaches to improve small fan unit efficiency, complimentary to, or in absence of, MEPS/HEPS 25 MEPS for small fan embedded inside larger appliances that already have MEPS? 26 Situations where the lower efficiency produces a useful by- product such as heat? 27 Certain appliances incorporating small fans where regulations would not be effective at improving efficiency 28Possibly consider domestic and industrial small fan units separately? 37

38 Discussion Points – Regulatory Considerations 29Extra costs for manufacturers and users to measure the efficiencies of small fan blades and motors 30Impact of regulations on different suppliers e.g. appliance manufacturer, fan blade manufacturer? 31Impact of requiring more efficient small fan blades and motors on the appliance cost? Effect on product competition? 32Compliance and enforcement issues of MEPS for small fan units 33Categories of small fan unit applications that offer more potential for MEPS
