About this course

This course was originally presented at BuildingEnergy Boston 2024, a conference presented by the Northeast Sustainable Energy Association (NESEA).

An existing house represents an enormous amount of “up front” carbon that has already been committed. The more we can re-use it, the less carbon we are releasing per unit of housing. But when is enough enough? This session is about finding the sweet spot between existing and desired, and how to balance expense vs savings.
