A passive house is usually a new build house. It is a highly efficient building with extremely high levels of insulation and air tightness. It is designed to reduce heating needs and energy demand to a minimum. It is not normally possible to achieve a passive house standard with a home retrofit unless the house is being stripped back to the four outside walls and rebuilt from a new floor all the way to a new roof.
