Abstract

As a vast Northern nation, Canada faces unique challenges in addressing climate change. Indeed, almost 63% of total energy consumption in Canada is due to space heating. This investigation compares two energy efficiency options for an existent 8-apartment building located in the region of Nova Scotia. First option (Option 1) corresponds to upgrading building envelope insulation with either low-thermal-resistance/low-cost material (sub-option 1-A) or high-thermal-resistance/high-cost material (sub-option 1-B). A second option (Option 2), consists of replacing the existing oil-boilers with electric-heaters. The Life-Cycle Cost Analysis pointed to insulation with higher thermal-resistance (Option 1-B) as the best option, with fuel savings of 11,4%, 2-year simple payback, IRR and NPV of 53.7% and 28,284 €, respectively, with Benefit-Cost ratio of 6.67, demonstrating that there is plenty space to implement effective and viable energy efficiency measures in the residential sector of Nova Scotia and, by extension, in other populated mid-temperate latitudes around the world.
