Introduction to special issue devoted to appliance and lighting standards

James E. McMahon, Isaac Turiel
Lawrence Berkeley National Laboratory, University of California, Berkeley, CA 94720, USA

1. Why a special issue?

Appliance and lighting standards have more than a twenty-year history, originating tin reaction to oil price shocks) in Europe and the US, and then in many regions of the world. In spite of the social, economic and environmental significance of appliance and lighting standards, the extensive history of these standards is largely available in voluminous legislative and technical documents, with only an occasional journal article or conference paper accessible to a wider audience. In this special issue, we are excited to bring together an international collection of summary documentation from a range of perspectives, presented by some of the key participants in this history. The authors share lessons to date in the areas of engineering, economics and policy analysis.

2. What are appliance standards?

Appliance standards are a set of procedures and regulations which prescribe the energy performance of manufactured products, sometimes prohibiting the manufacture of products less energy efficient than the minimum standard. The term 'standard' encompasses two possible meanings. We separate the two uses of that term as follows: (i) a well-defined protocol (or laboratory test procedure) by which one can obtain a relative ranking of energy efficiency among alternative technological designs providing an energy-consuming service; and (ii) a norm (target or mandatory limit) of energy efficiency or energy performance based upon the protocol.

3. Why are appliance standards important?

Appliances Ñ here broadly defined to include heating, cooling and lighting, as well as refrigerators, clothes washers and other household equipmentÑaccount for most of the energy consumption in buildings, and buildings account for much of electricity and natural gas consumption. In 1990, buildings (residential and services/commercial) used about 41% of electricity generated world-wide, and 37% of total primary energy [1]. In industrialized countries, energy consumption by appliances is already large, and in developing countries, such energy consumption is growing rapidly. The increase in electricity demand in developing countries, significantly from the use of appliances in buildings, is anticipated to require an average annual investment or new generation and distribution capacity from 1995 to 2010 of $97 billion.

Energy cost is not the only economic consideration. About 67 billion was spent in 1992 on 'white goods' (refrigerators, freezers, cooking appliances, microwave ovens, clothes washers, clothes dryers and dishwashers) and the expenditures are projected to grow to $77 billion per year by 2000 [3]. The world air-conditioning and refrigeration market, valued at $40-45 billion, is expected to grow to $50 billion by 2005 C4].Appliance standards have significant economic impact, directly affecting manufacturers, large populations of consumers andÑindirectlyÑenergy suppliers. Appliance standards have influenced manufacturers to invest more in designs using less energy, which in turn reduces the need for new energy supplies. For electricity, in particular, appliance standards can reduce the need for new capacity, in part because air conditioners exert disproportional influence on peak power requirements.

Not only have appliance energy standards already resulted in significant economic benefits, the potential for further savings is huge. Several estimates have been made of the energy savings potential from efficiency improvements in buildings worldwide. A study commissioned by the World Energy Congress (WEC) based on IPCC scenarios shows potential reductions in energy demand in buildings in the OECD countries of 616% and in countries with economies in transition and developing countries of 2544% when comparing aggressive efficiency scenarios to business-as- usual scenarios [ 51 . Much of this savings potential is from appliances, equipment, and lighting and much of that is achievable through energy standards.

Appliance standards also noticeably mitigate environmental emissions of carbon dioxide, sulfur dioxide and nitrogen oxides associated with burning fuels to provide energy. For example, the current US appliance standards are expected to prevent 107 million tons of carbon dioxide emissions (equivalent of 2% of US carbon emissions), prevent 286 thousand tons of nitrogen oxide emissions, and allow 385 thousand tons of sulfur dioxide emissions to be banked or traded in the year 2000 alone. In 1995, buildings account for about 25-30% of global energy-related carbon dioxide emissions, contributing 10-12% of the increasing net radiative forcing that is inducing global warming. The energy savings projected by WEC in its aggressive efficiency scenario would cut carbon emissions in 2000 dramatically from its business-as-usual projection [6]. In the context of policies for meeting inter national agreements on carbon emissions, international interest in appliance labels and standards and their harmonization is increasing.

4. What are the key issues?

Many developing and developed countries around the world are currently considering whether to introduce appliance standards, are in the process of introducing standards, or are undertaking modifications to existing standards. Important questions raised in the often contentious debates occur ring in each of these countries include:

How would the standards affect the availability and quality of consumer products?

What would be the impact (costs and benefits) of standards on consumers, manufacturers, national economies and the environment?

Under what circumstances is government intervention in the marketplace warranted?

How should the process of establishing standards be conducted?

For example, some argue that a government imposing standards interferes with the operation of the free market, and is in conflict with the current worldwide trend toward increased reliance on market forces. Others argue that a government imposing standards merely modifies the rules of the competition to the benefit of all, does nothing to reduce competition, and is totally in harmony with a nation's reliance on market forces.

This special edition does not resolve these issues. Importantly, it provides a factual foundation of the history of appliance energy standards to date to allow readers to engage in meaningful discussions towards their resolution. With worldwide interest in appliance standards growing rapidly, Turiel's article [7] offers a snapshot of the current status, listing those countries with standards and those about to adopt standards. It shows that mandatory energy efficiency standards are in place for some appliances in Canada, China, Korea, Mexico, the Philippines, and the United States; standards for refrigerator/freezers and water heaters will take effect in Australia in 1999; standards for refrigerator/freezers will take effect in the European Union in 1999; and voluntary energy efficiency standards are in place for refrigerators in India and Brazil and air conditioners in Japan and India.

The next three articles [8-10] deal with aspects of appliance standards that must be confronted in all countries. Appliance efficiency standards directly affect the way appliance manufacturers must design and build appliances. Therefore, it is essential to understand the view and experiences of manufacturers who have already faced standards. The article by Anderson and McInerney [8] gives two manufacturers' perspectives of appliance standards when faced with the multiple challenges of reducing energy use and phasing out CFCs while satisfying consumer's demands for amenities and low prices.

All appliance standards rely on energy testing protocols to ensure a fair and consistent measurement of energy use. Meier and Hill [9] describe some of the energy testing procedures and the testing problems for new appliances with micro processor controls where the software will become nearly as important as the hardware in determining energy performance.

There are several approaches to establishing efficiency standards for appliances. An article by Turiel et al. [101 describes and compares the different methodologies used to set standards. For a country considering developing standards, this article describes the choice between a statistical approach to setting standards and an approach relying on product ngineering and economic analysis. However, each country's experience with appliance standards is different and adds insights to the broader issues. Separate articles for Europe, Japan, Australia, Canada and California [ 1 1-15 ] explain the history, the process of adoption, and the details of standards in those regions.

Two further articles describe the impacts of energy savings. It is essential to verify that the efficiency improvements do indeed result in reduced energy use. The US has maintained a continuous process for establishing standards since 1978. Geller' s [ 16] article estimates the national impacts of the US standards, both with respect to energy savings and avoided costs. Meier [173 summarizes field measurements from several countries to show that energy savings do indeed occur.

As indicated earlier, the status of appliance efficiency standards is constantly changing. Nadel [18], in the final article of this edition, discusses the future of standards, test procedures, and energy labels.

Abstract


An energy test procedure is the technical foundation for all energy efficiency standards. It provides manufacturers, regulatory authorities, and consumers a way of consistently evaluating energy use. The ideal test procedure reflects actual usage conditions without compromising reliability and cost-effectiveness. Unfortunately, because these goals are contradictory, every test procedure is a compromise. Energy test procedures exist for a wide range of appliances and often each country has its own unique test procedure. The procedures for refrigerators, furnaces, air conditioners, clothes washers, and other appliances are described and compared. The emergence of microprocessor controls complicates developing specifications for a single operating schedule and simple comparisons of energy performance. Energy test procedures will face unprecedented pressures in the next decade as a consequence of international economic integration and technical innovations.

Abstract

In recent years there has been a revival of interest in appliance energy efficiency standards in Europe, in particular within the European Union ' (EU). This paper summarizes the activity that has occurred across continental Europe, from the EU to Russia, but focuses principally on Western Europe. The paper discusses the components of residential electricity demand by end use and the role played by appliances, the energy consumption and energy efficiency trends for selected appliances, the European appliance market, the development of the EU's mandatory energy labelling scheme and some of its results, the testing and certification institutions in Europe, the EU's mandatory minimum energy efficiency standards proposal for refrigerators and freezers but current preference for voluntary agreements, the maximum energy consumption standards in Russia, the Swiss target-value approach, and the savings potentials of appliance energy efficiency standards for 'cold' appliances, 'wet' appliances, leaking electricity, electric motors, and office lighting. Since this paper was written tin ]995), the EU has passed legislation to introduce mandatory minimum energy efficiency standards for refrigerators and freezers that will enter into effect in 1999. The standards are set at a level intended to ensure that models sold after 1999 will, on average, require 15'h less energy than the average of models sold between 1991 and 1992 after normalization for storage volume and cooling service. Despite these activities, the paper demonstrates that there remains a huge potential to save energy cost-effectively.

Abstract

Japan's first appliance energy efficiency standards were set in 1979 under the Energy Conservation Law and covered refrigerators and household air conditioners. In 1994 a number of appliances were added to the list of specified equipment. After explaining the process by which standards are established, we review the new standards for fluorescent lights, televisions, heat pump air conditioners, and copiers. The new standards are expected to exert a major influence on appliance efficiencies in Japan, reversing a decade-long trend of designers ignoring energy efficiency. Manufacturers will shift their product mix away from inefficient models.

Abstract


Household appliance penetration and ownership in Australia is higher than in western Europe, and close to North American levels. Most products are manufactured locally, by firms with international links and with access to both European and North American designs and technology. A significant share of the market is imported, mainly from New Zealand, Asia and Europe. Because of the relative mildness of the climate, appliances that carry an energy label (such as dishwashers, clothes washers, clothes dryers, and refrigerators and freezers) account for a greater share of household energy use than in most other developed countries. The energy efficiency of appliances in Australia increased steadily during the early 1980s, but the introduction of mandatory energy labelling in 1986 in some states saw a significant increase in the rate of change. The mandatory government energy labelling program, which is in force in most states, now includes refrigerators, freezers, room air conditioners, dishwashers, clothes washers and clothes dryers. A voluntary industry-based gas appliance energy labelling program is also in place for gas water heaters and flued space heaters. The Australian energy labelling program is widely regarded as among the most informative and salient in the world, and it may be extended to New Zealand over the next few years (many products in NZ already carry the label as the Australian and NZ markets are closely integrated). Label recognition and use is very high among recent and prospective appliance purchasers. The use of a static efficiency scale on the label, while assisting recognition and comprehension, has also reduced the competitive pressure on suppliers, as efficiency improvements have pushed many models to the top of the rating scale. In 1995, Australian energy ministers agreed to implement minimum energy performance standards (MEPS) for refrigerators, freezers, and electric storage water heaters, to take effect in 1999. The levels are relatively moderate, and the effect will be to complement the energy labelling program rather than to transform the energy efficiency of the market.

Regulating appliance energy efficiency in Canada: Some similarities and differences with the US

Jean-Pierre des Rosiers1, John Cockburn

Received 15 November 1995; accepted 12 December 1995


Abstract
The objective of Canada's energy efficiency regulations is to eliminate the most energy-inefficient energy-using products from the Canadian market by establishing minimum efficiency standards for certain energy-using equipment. Under the Energy Efficiency Act, regulations have been developed for a wide range of equipment. The Energy Efficiency Regulations, which came into effect in February 1995, apply to equipment imported into Canada and equipment manufactured in Canada and shipped from one province to another. Canada's energy- efficiency regulatory process differs significantly from that of the United States in a number of ways. The Canadian regulations, for example, have different verification, reporting, and importing requirements. Important distinctions also exist with respect to the legislative authority for the Canadian regulatory program. Nevertheless, despite the differences in approaches, processes, climate, energy prices and policy objectives, Canadian regulations are still greatly influenced by regulatory activities and trends in the United States. The North American equipment market is an integrated one, with a constant two-way flow of products across the Canada-US border. As a result, the market domination by US equipment manufacturers has a strong impact on energy-efficiency levels in Canada. One of the key future thrusts of Canadian regulators will be to pursue greater harmonization of regulatory requirements within Canada and among Canada, the United States, and Mexico, as well as globally. The goal is to establish an effective, comprehensive, and consistent energy-efficiency regulatory regime that will contribute to the achievement of economic and environmental objectives around the world.

Abstract

The California Energy Commission was the first government agency in the United States to develop Appliance Efficiency Standards. This article describes the origin of that agency and gives details of the successes and shortcomings of its twenty-year history in this field. Many of the California Energy Commission's standards have been copied in legislation and regulations of numerous other states, Canadian provinces, and the United States government. It is the author's hope that by sharing details of some of the good things and some of the not-so-good things that have happened, those who follow may be more successful than the author. The article concludes with a 'report card' that identifies several successful programs that the author would like copied, and a few pitfalls that he hopes will be avoided.

Abstract


This paper reviews the status of Federal appliance and equipment efficiency standards in the United States and summarizes the impacts these standards are having on consumers, manufacturers, and the nation. It shows that standards already adopted are expected to save consumers $132 billion net and displace the need for 31 large (500 MW) baseload power plants by 2000. Existing standards also will cut carbon dioxide emissions in 2000 by about 26 million metric tons, equivalent to about two percent of total US emissions or removing around 15 million automobiles from the road. According to analyses by the US Department of Energy, appliance efficiency standards have not had a negative effect on appliance manufacturers. The final section of the paper reviews the status of standards rulemakings underway as of early

Observed energy savings from appliance efficiency standards

Received 5 December 1995; accepted 5 March 1996

Abstract

No country has directly measured the actual energy savings resulting from efficiency standards, but many studies-mostly in North America-have indirectly observed savings. Methodological and practical obstacles to observing savings include the difficulty of defining baseline energy use and isolating the impact of technical improvements in efficiency from other changes in usage patterns. Laboratory measurements are cheaper and faster than field measurements, but they still must be calibrated to field use. Energy savings resulting from refrigerator efficiency improvements have been the most closely examined. Savings have been observed through laboratory comparison field measurements, and utility bill analysis. Actual savings correspond closely to those predicted in laboratory tests. Reductions in energy use from improvements in efficiency have also been observed for both heating and cooling equipment. Laboratory-measured differences in efficiency generally give accurate estimates of percentage savings, but give poor estimates of absolute savings. Energy savings from efficiency improvements have also been observed for freezers, water heaters, and showerheads. The generally large percentage savings observed in North America may also apply to Europe and Japan although the absolute savings will be smaller. Savings from new standards created in these countries must be verified.

Received 3 December 1995: accepted 10 October 1996


Abstract

In this paper, we discuss the future of efficiency standards, including revisions of existing standards, the spread of standards to other countries and other products, the use of voluntary standards and other complements to mandatory efficiency standards, international harmonization of standards, manufacturers' reactions to standards, how standards may be used to promote classes of products that save energy, and evaluation and documentation of standards. We conclude that trends towards increased use of standards in terms of number of countries and number of products covered are likely to continue, along with periodic updates to standards and growth in programs that complement standards.
