ENERGY STAR Changes for Windows and Doors in 2020

The Government of Canada announced in April of 2019 a new standard for the ENERGY STAR program. This announcement included updates to doors, windows, and skylight standards for all Canadian door and window manufacturers, installers, and home builders.

So what exactly does this mean? Keep reading to find out what changes are coming for ENERGY STAR ratings for windows and doors in 2020.


ENERGY STAR is an Environmental Protection Agency voluntary program based in the United States. Their goal is to help both individuals and businesses alike save money for their efforts to protect the environment through energy efficiency efforts.

Products of all kinds are energy efficient certified, indicated by the recognizable blue ENERGY STAR symbol. This seal of approval is meant to provide comprehensive and unbiased information regarding these products in order to help consumers make responsible, eco-conscious decisions for their homes or businesses. Almost all of the industries cooperate with ENERGY STAR to ensure a better environment – a cleaner air and a better future.

Since 1992, ENERGY STAR helped the average family save 4 trillion kilowatt-hours of electricity and helped reduce 3 billion metric tons of greenhouse gas. This eventually helped families save a total of $30 billion in energy costs.

What makes it ENERGY STAR?

It’s not easy for a product to become an ENERGY STAR approved item – it has to go through a lot of tests and experiments before it can be recognized as such. The criteria any door or window must meet in order to fit the standard set by ENERGY STAR includes the following:

  • It has to be manufactured by an ENERGY STAR partner
  • It has to be independently tested as well as certified by the National Fenestration Rating Council (NFRC)
  • It meets the ratings provided by NFRC as well as the US Environmental Protection Agency (EPA).

ENERGY STAR Window Criteria

In order to have an ENERGY STAR window rating, the window must be able to protect you from harsh elements such as those we experience in winter. These windows should effectively keep you warm during winter and keep you cool during summer. The performance criteria approved by the National Fenestration Rating Council (NFRC) for windows and skylights would be:

ENERGY STAR Door Criteria

In order to get the ENERGY STAR seal of approval, doors need to meet a different set of criteria. While an entry door may have glass inserts, they still have a much lower glass-to-frame ratio in comparison to windows and skylights. This means that doors generally provide more insulation compared to their full glass counterparts.

The performance criteria for doors are based on how much glass it does have (it’s also called glazing level) and ratings certified by the NFRC:

New Guidelines for ENERGY STAR Windows and Doors

As energy effectiveness is an ever evolving objective, the administration divisions behind the ENERGY STAR program occasionally update the standards on what is viewed as energy proficient. Through a mix of industry upgrades, innovation progressions and manufacturing changes, the ENERGY STAR program will acclimate to what it regards as a product for energy effectiveness.

For this most recent change, Natural Resources Canada adjusted the ER and U-Factor for private windows and doors. Normally, as this is a North American program and these standards are written in both Kelvin which is the worldwide science standard, and in Fahrenheit for North American based producers.

As of January 1, 2020, for windows and doors to be regarded as an ENERGY STAR item, they must meet or surpass a 1.22 whenever estimated in Kelvin or 0.21 when estimated in Fahrenheit. If the door or window is ever given an estimation in the alternative ER unit, the window or door should meet or surpass 34.

On the other hand, skylights must at least meet or surpass a 2.29 Kelvin U-Factor, while in Fahrenheit it needs to meet or surpass 0.40.

ENERGY STAR 2020 Standards

As of January 1, 2020, there is a new set of guidelines on how to label the ENERGY STAR doors, windows, and skylights in Canada. Here, you will be able to understand the ENERGY STAR requirements for Canada:

The ENERGY STAR Name & Symbol Are Now Registered in Canada

This means that the U.S. Environmental Protection Agency (EPA) has officially registered ENERGY STAR with the Canadian Intellectual Property Office with the promotion and guidance of Natural Resources Canada (NRCan). In order to use the ENERGY STAR name and logo in Canada, you will need a signed agreement in a Participant Administrative Arrangement with NRCan. If there is evidence of misuse, the contract will be terminated and it will be reported to EPA.


There are new labelling guidelines for Canadian ENERGY STAR, and it’s for fenestration Version 5.0. Manufacturing participants may start labelling for Version 5.0 on December 1, 2019. The label layout with a combination of Canada-U.S. map showing confirmation in all of Canada can, in any case, be utilized. The label layouts demonstrating accreditation in Canada only to all 3 climate zones (content or map) can be utilized until the end of 2020.

There are numerous ways you can check if the items you bought has an ENERGY STAR door rating or ENERGY STAR window rating, it is usually specified on the label and provides thorough information on each product.
