Home of Today/Home of Tomorrow: a real-world study on sustainable homebuilding

Okanagan College

Recent EnerGuide testing has shown the Home of Tomorrow, one of two homes that make up the Wilden Living Lab project, to be 52 per cent more energy efficient than a standard home constructed to today’s building code.

The Home of Today and the Home of Tomorrow ­– two houses constructed side-by-side in the popular Wilden neighbourhood ­­– are part of a real-world study on sustainable homebuilding that compares the energy usage patterns of identical structures built with different energy-efficient technologies.

The pioneering initiative is collaborative three-year learning and research project by Wilden developer Blenk Development Corp., AuthenTech Homes, UBC Okanagan, Okanagan College and FortisBC.

Following the completion of construction of both homes in early November, the Living Lab partners enlisted an energy evaluation company to analyze the performance of each home based on the Government of Canada’s EnerGuide standard ratings for new homes.

Gilles Lesage, operations manager of Total Home Solutions, conducted the testing on insulation levels, airtightness, windows and door types and space and hot water heating systems. The Home of Tomorrow achieved an exceptional EnerGuide rating of 47 gigajoules (GJ) per year and greenhouse gas emissions of only 0.3 tonnes per year in the energy audit. In comparison, the Home of Today, which was built to current building code standards, has a rating of 110 GJ/year and GHG emissions of 3.0 tonnes/year.

Lesage attributes the efficiency rating to the sustainable construction of the Home of Tomorrow.
