Tougher ENERGY STAR Specification Proposed for Gas Furnaces

The ENERGY STAR qualifying level for gas furnaces will get tougher next fall if a proposal by ENERGY STAR receives final approval.

Version 2.1 of the ENERGY STAR specification for furnaces, released for discussion in  2007, calls for gas furnaces to achieve an Annual Fuel Utilization Efficiency (AFUE) rating of 92% or higher effective October 1, 2008. Under the current specification (Version 2.0), the ENERGY STAR qualifying level for gas furnaces would remain at AFUE 90% on October 1, 2008, while the qualifying level for oil furnaces would increase from a minimum AFUE rating of 83% to a minimum of 85% (the requirement for oil furnaces remains unchanged in the new specification).

Industry stakeholders have agreed that the proposed new requirement is a viable change that will help ensure that manufacturers continue to innovate and bring more efficient models to market. Approximately 35% of models listed in the NRCan Energy Efficiency database already have an AFUE rating of 92% or higher. Natural Resources Canada has advised ENERGY STAR that it supports the proposed increase in the ENERGY STAR qualifying level for gas furnaces. The economics are also very attractive for the Canadian climate.

In releasing Version 2.1 of the ENERGY STAR furnace specification, ENERGY STAR confirmed that fan efficiency requirements will not be included in the specification at this time due to concerns about the accuracy of test procedures and regional differences. ENERGY STAR will monitor efforts to improve the current test procedure and may revisit this issue in future versions of the furnace specification.

Updates on the specification development process, including comments received from stakeholders, can be found on the U.S. ENERGY STAR product development Web site at (click on Revisions to Existing Specifications).


Updated ENERGY STAR Spec for Residential Light Fixtures Affects Products with GU-24 Bases

Version 4.1 of the ENERGY STAR specification for residential light fixtures has been finalized and will take effect on August 1, 2008. The updated specification affects only products that use GU-24 bases and aims to ensure high-quality performance as the market for these products expands.

In order to continue using the ENERGY STAR symbol after the effective date, fixture manufacturers are required to ensure that both existing and new products using GU-24 bases meet the strengthened performance requirements. Fixture manufacturers are encouraged to begin addressing this issue with their suppliers as soon as possible.

Manufacturers can start to qualify their products under Version 4.1 immediately. Information on changes to the process for submitting products for qualification will be distributed to ENERGY STAR participants by e-mail and will be posted to the U.S. ENERGY STAR's Lighting Product Resources Web page at

Note that the U.S. ENERGY STAR program qualifies all light fixtures for both Canadian and American markets. For manufacturers and dealers wanting to qualify their products, they must contact the U.S. ENERGY STAR program.

As of August 1, 2008, fixture models using GU-24 bases that qualified for ENERGY STAR under the Version 4.0 specification but have not been requalified under Version 4.1 will be removed from the EPA's qualified products list. As well, manufacturers will be required to discontinue using the ENERGY STAR symbol to market these models.


ENERGY STAR Specification for Refrigerators to be Strengthened in April 2008

The new ENERGY STAR specification for standard-size residential refrigerators comes into effect on April 28, 2008. This specification will ensure that only the top energy performers on the market are eligible to use the ENERGY STAR symbol of energy efficiency. The specification affects only standard-size refrigerators that are 7.75 cubic feet (215.5 litres) or larger and raises the level of energy efficiency to 20 percent above the minimum federal standard.

More than half of all refrigerator models available for sale in North America now qualify for the ENERGY STAR symbol, a fact that has led the U.S. Department of Energy (DOE) to propose a new ENERGY STAR specification for this product line.

When the current ENERGY STAR specification for residential refrigerators and freezers came into effect on January 1, 2004, very few models could meet the qualifying criteria. The situation has changed dramatically over the past three years, however, as new refrigerator models and new technologies have been introduced to the market. ENERGY STAR qualified models accounted for 37% of residential refrigerator sales in Canada in 2006.

To ensure that the ENERGY STAR symbol continues to differentiate the most energy-efficient products on the market, ENERGY STAR is proposing to strengthen the qualifying criteria from the current level – which requires that models be 15% more energy efficient than the regulated federal standard – to 20% more efficient than the federal standard. The levels for freezers, compact refrigerators and compact freezers will remain unchanged. The proposed date for the new criteria is April 1, 2008.

According to a market impact analysis done by the U.S. DOE, strengthening the qualifying level by 5% would have major national impacts on energy consumption and utility bills (consumers would save an average of US$150 in electricity costs over the 14-year life of the product). The analysis also concluded that the 20% level for ENERGY STAR qualification is technologically feasible, as models that meet these criteria are already available in most sizes and configurations.

Natural Resources Canada agrees that the ENERGY STAR qualifying level for refrigerators should be increased from 15% to 20% above the federal regulated standard, which is the same in Canada as in the U.S. NRCan also agrees with the DOE's conclusion that no changes should be made in the qualifying levels for freezers, compact refrigerators and compact freezers. The qualifying level for compact refrigerators is already 20% above the federal standard. In the case of freezers, changing the requirement would likely leave consumers with a very limited number of ENERGY STAR qualified models in the Canadian marketplace. No compact freezer models currently qualify for ENERGY STAR in Canada.

NRCan has also endorsed the ENERGY STAR proposal to improve the wording and instruction in the test criteria for refrigerators to prevent circumvention of the criteria with modern technology and sensors. Similar changes have been proposed to the Canadian standard CSA-C300, which is currently under revision.

More information on the DOE proposal is available at


ENERGY STAR Specification Finalized for Commercial Dishwashers

The list of products eligible to qualify for the ENERGY STAR symbol continues to grow with the addition of commercial dishwashers effective October 11, 2007.

As noted in the previous edition of ENERGY STAR News/Nouvelles, a draft of the ENERGY STAR specification for commercial dishwashers was released in March 2007. Based on stakeholder feedback, additional changes have been made to the specification. Specifically:

  • The definition for under counter machines has been clarified to exclude machines designed for wash cycles longer than 10 minutes in order to further differentiate between residential style models and machines designed for a commercial food service environment.
  • A new 30-second load time was added for door-type machines that are designed to be front loading.
  • The reference to the test standard NSF/ANSI 3 has been updated to reflect the latest 2007 edition.

Commercial dishwashers must meet the requirements provided in the table below to qualify for ENERGY STAR. Machines designed to be interchangeable in the field from high temp to low temp, and vice versa, must meet both the high temp and low temp requirements.

Efficiency Requirements for Commercial Dishwashers

Machine Type High Temp Efficiency
Low Tem Efficiency
  Idle Energy
Idle Energy
Under Counter <= 0.90 kW <= 3.8.1/rack <= 0.5 kW <= 6.4.1/rack

Multiple Tank
<= 2.6 kW <= 2.0.1/rack <= 2.0 kW <= 2.0.1/rack

* Idle energy rate as measured with door closed and rounded to 2 significant digits.
** Includes pot, pan, and utensil machines.

The final specification, as well as all EPA correspondence, stakeholder comments and previous drafts of the specification, can be viewed on the ENERGY STAR's New Product Specifications in Development Web page at


Commercial Ice Machines Added to ENERGY STAR Lineup

Watch for the ENERGY STAR symbol to start appearing on qualified models of commercial ice machines early in the new year. The final specification was released in July with an effective date of January 1, 2008.

The specification defines an ice machine as “a factory-made assembly (not necessarily shipped in one package) consisting of a condensing unit and ice-making section operating as an integrated unit, with means for making and harvesting ice. It is an assembly that makes up to 1,814 kg of ice per day at Standard Ratings Conditions, as defined in CAN/CSA C742-98, and may also include means for storing or dispensing ice, or both.”

Ice machines that use water-cooled technology, as well as flake and nugget ice machines are not eligible for ENERGY STAR under this specification. However, these machines may be included in a future revision of the specification.

Commercial ice machines must meet the requirements in the table below to qualify for ENERGY STAR. The test standard is CAN/CSA C742-98 “Performance of Automatic Ice-Makers and Ice Storage Bins”.

>= 79 721.5 <= 2.9

Automatic ice-makers are a regulated product under Canada's Energy Efficiency Regulations. However, Natural Resources Canada is planning to update the existing requirements and amend the Regulations to strengthen the minimum energy efficiency requirements for both air-cooled and water cooled automatic ice-makers. The ENERGY STAR qualification levels only cover air-cooled and are about 10 percent more stringent than NRCan's proposed new regulated levels.

An estimated 80 000 ice-makers are in commercial use in Canada today. Assuming average ice production of 160 kg/day and energy consumption of 706 kilojoules per kilogram of ice produced, the combined annual energy consumption of commercial ice-makers in Canada is estimated at 3.3 million gigajoules – equivalent to the annual energy use of about 40 000 Canadian households.

News from ENERGY STAR for Fenestration Products

The past few months have been a busy time in the fenestration product sector. Many applications for ENERGY STAR registration have been received from product manufacturers, dealers and component suppliers. Various local and provincial incentive programs for purchasing ENERGY STAR qualified windows, together with the provincial sales tax exemption in British Columbia and the Government of Canada's ecoENERGY Retrofit program, have all contributed to growth in this product sector. The number of participating manufacturers is rapidly approaching 150, and there are now many participating dealers across the country.

Registered participants are reminded that, beginning January 1, 2008, NRCan will start to phase out ENERGY STAR qualified product models certified to the NFRC 97 and CSA A440.2 98 standards. The phase out will be completed by April 1, 2008, after which any remaining product models certified to these versions of the standards will be removed from our Web site.

Manufacturers are also reminded that it is important to label their qualified product models with the Fenestration Qualification Label (FQL). The FQL is used by many incentive programs as proof-of-purchase of a qualified product. If the FQL is not on the product, your customers may not receive grants or rebates for which they are eligible. As well, please keep your product model listings current on our Web site.

In support of the various incentive programs and to better track the many product models now qualified for ENERGY STAR, an NRCan reference number has been developed for both the listed brand names and the product models. Each brand name has been given a number, and most are shown on the participating manufacturers list on the ENERGY STAR Web site. This number forms part of the complete reference number for each qualified model, which also can be found on the Web site (click on the brand name in the initial list of product models to go to the model's detail page).

Finally, manufacturers are advised that NRCan, in cooperation with the U.S. Department of Energy, has begun to review the ENERGY STAR qualification criteria for windows, doors and skylights, with a possible implementation date for a new specification in early 2009. The Canadian ENERGY STAR labelling guidelines are also under review. Watch for more news on these matters in future editions of Canada ENERGY STAR.


Version 3.1 of ENERGY STAR Calculator soon to be Available On-Line

Want to know how much money your organization can save by purchasing ENERGY STAR qualified products rather than conventional models? It will be easier than ever, thanks to the release of an updated version of the ENERGY STAR Simple Savings Calculator. This update will include more qualified products and should be available on-line soon.

With a minimum of data input, the Simple Savings Calculator provides a comparison of annual operating costs and life-cycle costs for a wide range of ENERGY STAR qualified and conventional products. It supports comparisons of commercial and industrial products; lighting and signage; heating, cooling and ventilation equipment; home appliances; consumer electronics; and office equipment.

Although the calculator is designed primarily for use by procurement officials in business, industry and government, it can also help individual consumers make economical purchases for the home.

Two versions of the calculator are available:

  • The on-line version allows you to compare one model of an ENERGY STAR qualified product with one conventional model (the comparison can involve multiple units of a single model). This version can only be used from NRCan's ENERGY STAR Web page and does not save any modified settings when the session is terminated.
  • An Excel version of the calculator can be downloaded from the Web site or opened on-line (Excel 2000 or higher is needed). This version allows you to simultaneously compare up to three ENERGY STAR qualified models with one conventional model. As well, many of the default values and assumptions in the Excel version of the calculator can be customized by the user.

NRCan Unveils Home Heating System Cost Calculator

Canadian consumers who are in the market for a new home heating system – either to replace an existing furnace or for installation in a new house – now have access to a great new tool to help them make an economical choice that will save them money for years to come.

NRCan's Office of Energy Efficiency has developed the Home Heating System Cost Calculator to help homeowners compare the costs of electric, natural gas, propane and oil systems. The calculator was posted to the OEE's Web site this fall, just in time to help homeowners who might be considering a new heating system for the coming winter.

The calculator allows homeowners to compare an existing heating system with new technologies available on the market, or to run a comparison of various heating options for a new house. While the results can help guide the decision-making process, the OEE cautions homeowners to consult a heating contractor or other qualified professional for a detailed evaluation and cost estimates before making the final decision.

The Home Heating System Cost Calculator can be found at


Web Site Offers Information on Energy-Efficient Commercial/Institutional Equipment

For commercial businesses and public institutions, conserving energy means saving money – it's that simple. Which helps explain why more and more commercial and institutional organizations are turning to the Office of Energy Efficiency for help in buying and using energy-efficient equipment.

EnerGuide and ENERGY STAR – two programs administered by the OEE in Canada – provide information and tools to help businesses and institutions purchase, operate and maintain energy-efficient equipment and major appliances. Often, making the right choice can be as simple as checking a product for the ENERGY STAR symbol or EnerGuide rating.

The OEE also maintains an extensive Web site of information on energy-efficient, off-the-shelf equipment for commercial and institutional use. Found at, the site provides information on a full range of commercial/institutional equipment, from arc welders and boilers to motors, pumps to lighting products. Links are also provided to sites that offer information on other types of products commonly purchased by commercial and institutional organizations, such as consumer electronics, office equipment, major household appliances and heating equipment and controls.

The ENERGY STAR Purchasing Tool Kit is another popular feature of the OEE's commercial/ institutional equipment Web site. The kit explains how to overcome barriers to buying energy-efficient equipment and provides purchasing guidelines for a range of products eligible to use the ENERGY STAR symbol in Canada. It also provides a direct link to the ENERGY STAR Simple Savings Calculator, which as noted elsewhere in this newsletter has recently been revised and improved.

If you are looking for information on energy-efficient commercial and institutional equipment – including products that qualify for ENERGY STAR – the OEE Web site is a great place to start.
