Yellow or blue? Thermal imaging project in Vancouver to identify home heat loss
Vancouver has launched a project to determine if thermal imaging of homes could help residents identify heat loss and save on energy costs.
The city says thermal images show the temperature over the surface of a house and that a bright yellow colour would indicate heat leaks that may require improved insulation or better windows.
A dark blue colour would appear over a cold surface, suggesting heat is not escaping from a home.
The city says in a release that research from the universities of British Columbia and Calgary indicates that thermal imaging of homes could be a reasonably accurate tool to identify where a home is losing heat.
