Why We Must Improve Energy Efficiency Together

October 25, 2017

Today, there is no shortage of media coverage regarding greenhouse gases and climate change. As it is, more and more forward-thinkers are trying to bring attention to the near future, and it’s clear that there’s much more at stake than just the need to improve energy efficiency at home.

For climate change experts, doing retrofits to improve energy efficiency in a residential home or commercial building is a short-term solution. And while there are money savings by reducing energy consumption, everyone needs to be more aware about climate change as the “big picture".

By any definition, the opportunities for property owners to improve energy efficiency continue to be appealing. This is partly because consumers are quite motivated by the savings on utility costs. The truth is, however, there’s much more to consider than efforts to improve energy efficiency.

Energy savings is only part of the climate change story. The big story is about the substantial reduction of greenhouse gases. And that means having a conversation that goes beyond upgrades and retrofits to improve energy efficiency. There must be more talk about climate mitigation.

Convincing consumers about energy efficiency

More and more consumers are convinced that their homes can function more effectively by doing things to improve energy efficiency. It translates into reduced heating costs and cooling costs, but it also translates into reduced carbon footprints. This is particularly true for the millennials.

The big challenge going forward (for homeowners and business owners) is to cut greenhouse gas emissions that will meet reduction targets defined by the province of Ontario. Here again, the big picture for consumers is saving money PLUS reducing energy PLUS reducing carbon footprints.

An action plan to improve energy efficiency

For property owners who are motivated to make significant improvements to energy efficiency, Great Northern Insulation offers an innovative “online” tool to get things going. It’s an ideal way to learn about the performance deficiencies that contribute directly to poor energy efficiency.

The online tool from GNI is named My EnergyXpert, and allows property owners to get better acquainted with various aspects of energy performance. The tool provides an energy appraisal that identifies energy upgrades and retrofits that could save 25% or more on energy usage.

Once the energy appraisal is complete, the experts at Great Northern Insulation can recommend a variety of upgrades and retrofits that would improve energy performance. This would include such things as weatherizing, air sealing, and insulation - all of which would be improvements.

GNI specializes in energy performance for both residential and commercial customers. Our technical teams are trained, skilled, and experienced in all aspects of energy efficiency. We do everything according to the building code and always recommend the cost effective approach.

To arrange for a property assessment and project recommendations, contact the professionals at Great Northern Insulation by calling toll free at 1-800-265-1914. To learn more about energy efficiency and various GNI services, visit the company website at www.gni.ca.

Foam Masters

Do it right the first time
- with foam mastersTM

January, 2021 regulatory phaseout of hydrofluorocarbons (HFCs) with the introduction of WALLTITE CM01. Using hydrofluorolefins (HFOs) with lower global warming potential (GWP) compared to HFCs, WALLTITE CM01 is the next generation of spray foam insulation.



Heatlok® Soya HFOTM leverages Honeywell’s latest Solstice® Liquid Blowing Agent technology. This new hydrofluoroolefin (HFO) blowing agent is the most environmentally conscious blowing agent produced to date, with a zero ozone depletion potential (ODP) and a global warming potential (GWP) of 1, which is more than two orders of magnitude (99.9%) lower than HFCs used in this industry.
