What are the benefits of whole house retrofit?

Whole house retrofit is an approach to delivering energy efficiency measures to your home in a methodical way. It takes a holistic approach to ensure that certain measures aren't undermined by the lack of supporting measures. For example, air tightness measures help to prevent the undermining of insulation works by preventing heat loss but will then require a strategy to deal with ventilation. A whole house approach ensures that all risks of unintended consequences are considered.

Will a whole house retrofit make my home more energy efficient?
