While there is a push to incorporate energy efficiency measures into new buildings and homes to meet net-zero targets, a case study finds the benefits do not always justify the additional construction price tag for consumers.The homes used for the study were two halves of a semi-detached in Milton, Ont. – one was an all-electric home designed and built to the net-zero energy program.
The study explores the relationship between annual energy use simulation software modelling versus real-world data. For the net-zero side of the house, approximately a $51,000 upgrade in features was added to achieve National Building Code Tier Five performance. On the hybrid house there was about $4,000 in upgrades to achieve Tier Four performance.
