Understanding the ENERGY STAR® for windows and doors effective since early 2015

[All Tips]

When the winter is freezing, it is not surprising to receive quite expensive Hydro-Québec bills. As you know, governments are concerned about reducing energy costs.

Since 2015, in order to massively reduce energy losses, the federal government submits windows and doors manufacturers to higher energy efficiency standards. Since February 1st 2015, Natural Resources Canada (NRCan) has tightened the requirements of the ENERGY STAR® program.

For the certification of windows and doors, Canada is now divided into 3 climate zones (1, 2 and 3). Quebec covers two zones, zones 2 and 3. These climate zones are based on an average annual temperature indicator: Degree-Days of Heating (HDD).

Also, since the revision of 2015, NRCan is more strict in regards to the certification of entry doors. To qualify for ENERGY STAR®, doors must now meet the performance criteria of NAFS-08 as required by the 2010 National Building Code. Entry door manufacturers must now submit their steel doors to the same rigorous laboratory tests to which windows and sliding doors are subjected for accreditation.

In addition to tighter geographical areas and enhanced standard, NRCan requires new performance standards that refer to an increased energy rating (ER) minimum for most cities in southwestern Quebec. More precisely, zones 2 and 3 are reduced to a minimum ER of 29 and 34.

How to choose your ENERGY STAR® products?

1. Determine your climate zone

To facilitate your shopping, we advise you find out the climate zone in which you live. This way, you will speak the same language as the seller, and he will present you with certified products for that area. You can find out your ENERGY STAR® climate zone using your area code here.

The climate zone for which a door, window, or skylight is ENERGY STAR ® qualified will be listed on the product label and in the brochure.

Note that all our product labels have been updated, as well as all performance tables for each type of product that you can find on our website. As for our brochures, they will be updated gradually according to their renewal.

2. Choose a product suitable for your area

To make the best energy choice, rely on the ER Index. Over it, the higher the window or door’s performance. The energy efficiency rating (ER) compares all types of fenestration products, regardless of their materials and characteristics.

Be aware that a large number of windows and doors are certified for more than one area. You could save even more money on your energy costs by purchasing a certified product for a cooler area than where you live.

However, if you buy a window designed for a warmer area than where you live, you may find that it does not insulate as well as you’d expect.

Why purchase ENERGY STAR® windows and doors?

A new, energy efficient and properly installed will:

  • reduce energy consumption and save money. Energy savings typically range from 7 to 12% .
  • increase your comfort: reducing drafts and sound transmission
  • reduce condensation on the glass
  • reduce our impact on the environment
  • to be eligible for a refund if an aid program for ecological renovation or other is in effect at your purchase, such as LogiRénov, Novoclimat, Desjardins Green Homes Program, Energy Star certified windows for rental properties, etc.

What about “LOW-E” glass?

First, LOW-E glass, or energy efficient glass, is coated by a thin transparent metal film microscopically applied to the inner surface of glass, which, combined with the argon gas inserted between the glasses, greatly increases the performance of a sealed unit.

All ENERGY STAR® certified products are automatically LOW-E, but not all LOW-E products are ENERGY STAR®. The difference lies in the possible alteration of the effectiveness of a LOW-E glass depending on the options chosen. For example, the addition of grilles or fake mullions reduces the ER factor.

In conclusion, ENERGY STAR® is a measure of energy efficiency. By choosing windows and doors Fenplast you are not mistaken, because the majority of our products are certified ENERGY STAR®.
