The ENERGY STAR Canada symbol is recognized and trusted by Canadian consumers. Identifying tested high efficiency products that meet the current standards of Canadian government certification.


Maple Leaf IconENERGY STAR Canada is a voluntary partnership between the government and more than 1,000 organizations working to use our natural resources more wisely through greater energy efficiency run by Natural Resources Canada (NRCAN). Behind each ENERGY STAR Canada label is a product that is certified to use less energy, reducing emissions that contribute to climate change.

Energy Star 2022 Special Recognition Logo

Columbia is recognized by ENERGY STAR Canada for the second year in a row. Columbia is proud to be the only skylight supplier to the Canadian market to have been recognized by ENERGY STAR Canada.

Energy Star Sustained Excellence Award 2021

As recognition of Columbia’s commitment, we were the recipient of the 2021 ENERGY STAR Canada Sustained Excellence Award, acknowledging our long term performance in producing the most energy efficient skylights in Canada.

We all need to do our part for a sustainable future

Energy Star Right Choice

Reducing the impact of climate change through our actions as consumers has become a critical issue. There’s a social responsibility for us as individuals and companies to do the best for our planet – let’s all do our part.

At Columbia we are committed to this mission and have allocated resources to fulfilling the goal – across our research and development, manufacturing processes, and use of parts and materials.

We recycle all waste aluminum, glass, acrylic, corrugated cardboard and PVC, and employ sustainable practices throughout our manufacturing process, plant and warehouse.

Energy Efficient Home Plan

  • Plan to use ENERGY STAR Canada certified products when you build, renovate, or replace your home. ENERGY STAR Canada will help you evaluate products and options.
  • Work with your architect and/or contractor to specify ENERGY STAR Canada products, such as Columbia Skylights.

Energy Star Skylights In Winter

  • Skylights can be part of an entire energy efficient system for your home, combining current building products, technology and materials.
  • Think of your home as a complete integrated energy saving system, every element needs to be contributing to the home overall energy efficiency score.

Energy Efficient Wind Turbines

  • We all need to make energy efficient choices for the planet’s future. Both consumers and manufacturers must make the right energy efficient choices.
  • Columbia uses the latest materials and technology to help us produce the most energy efficient skylights in Canada.

How to read Columbia’s ENERGY STAR Canada qualification label

Here is a guide on how to read the ENERGY STAR Canada label so you are able to choose the most energy efficient products for you and your family. On the label are all the test results and how your skylight performs.


Energy Star Label

  1. Look for the official ENERGY STAR Canada logo
  2. Canada only has one region.
  3. Official NFRC Certification. Assurance that you product has been tested.
  4. Product manufacturer, name and description.
  5. U-Value and
    Solar Heat Gain Coefficient rating. The lower the better.
  6. Visible light transmittance rating – the higher the rating, the more light transmitted.
  7. Manufacturers confirmation that the data is accurate.

The performance rating explained

  • The thermal evaluation and certification of skylights are based on a number of criteria. They are reviewed below.
  • All of these performance criteria have a different impact on your skylight’s energy efficiency and work in unison.

U Value Degree Of Heat Loss

U-Value – Degree of Heat Loss
  • U-Value is the measure of the insulating characteristics of the glass, or how much heat flow or heat loss occurs through the glass due to the difference between indoor and outdoor temperatures.
  • How quickly heat from hot air (not direct sunlight) will pass through the glass.
  • U-Values generally range from 0.1 (very little heat loss) to 1.0 (high heat loss) BTU/h∙ft2F. The lower the U-Value the better the insulation.
  • The NRCAN utilizes U-Value to determine certification for the Canadian ENERGY STAR program.
  • Some ways to improve U-Values:
    • Use double or triple glazed glass units.
    • Argon gas in the cavity between panes of glass.
    • Optimize the cavity size between panes of glass.
    • Warm-edge spacers that create an effective thermal barrier.
    • Use LoE3 coatings (coatings can be used on more than one surface).

Solar Heat Gain Coefficient Shgc

Solar Heat Gain Coefficient, SHGC
  • Solar Heat Gain Coefficient (SHGC) is the amount of solar radiation passing through a skylight — either transmitted directly and/or absorbed, and subsequently released as heat inside a home.
  • The amount of Solar Heat Gain is expressed as a number between 0 and 1. The lower a skylight’s Solar Heat Gain Coefficient, the less solar heat is transmitted.
  • Objects (such as glass) impacted by sunlight absorb its visible and short-wave infrared components, increase in temperature, and then re-radiate that heat at longer infrared wavelengths.
  • Solar gain is used as a standard way of reporting the thermal properties of skylight and window assemblies

Visible Transmittance Vt

Visible Transmittance, VT
  • Visible Transmittance is the amount of light in the visible portion of the light spectrum that passes through the glass and into your home.
  • VT – expressed as a number from 0 to 1. The higher the number, the greater the amount of light that is passing through the glass.
  • High-performance skylights with LoE3 coatings can allow relatively high amounts of visible light to pass through the glass while repelling the solar heat gain – the more solar heat gain being filtered out, the less light transmittance.
  • Some examples:
    • VT .5 would be 50% of the light is entering the home.
    • VT .80 would be 80% of the light is entering the home.


ENERGY STAR Canada, part of a complete
sustainable home system

Using ENERGY STAR Canada certified products can turn your home into an energy saving system. By choosing skylights, windows, and doors with the superior energy rating, you create a consistent barrier against energy loss and are able to regulate the interior climate – increasing your home’s comfort and energy efficiency.

  • It is important to utilize all the components of your house in the battle against energy loss, such as insulating the walls and roof with the latest ENERGY STAR® Canada rated materials.
  • Venting skylights can naturally cool your home in the summer by releasing hot air that has collected in your living space, reducing your reliance on air conditioning.

Energy Efficient Home Windows Skylights And Insulation

For maximum energy efficiency, don’t mix double and triple glazing, and properly insulate your walls and ceilings

  • When specifying your renovation or new build, it is not recommended to try and save money by not using the same rating of ENERGY STAR Canada glazing throughout the home.
  • If you’re investing in triple glazing, it is optimal to use it for all skylights, windows, and doors. Creating a consistent barrier against energy loss.
  • The greatest impact on your home’s energy efficiency is to properly insulate your walls, ceiling and roof space.
Hot Air Rising In House

Hot air rises – naturally cool your home and save money in the summer with venting skylights

  • Venting skylights allow you to moderate interior temperature caused by solar heat gain, cooking, laundry and human activity. Enjoy the benefits of cross ventilation to cool your home.
  • LoE3 coated glass reduces Solar Heat Gain from the more intense and higher summer sun.

Solar panels and skylights - perfect partners

  • When you are replacing your roof consider installing solar panels and skylights, they can work in unison to create a more comfortable and energy efficient home.
  • Reduce the reliance on costly energy consuming air conditioning.
  • Solar panels generate electric energy to run your home, and venting skylights expel hot air in the summer, and provide ventilation year round.
  • Plus, you get the added health benefit of letting fresh air into your home and releasing dust, doors and airborne pollutants.
