Exterior Walls and Ceiling Furred Out

We have an existing building that lacked insulation in exterior walls as well as the ceiling. In order to accomodate the new insulation and some additional roof structure, the ceiling and walls were furred out, leaving the existing finishes in place (e.g. not being demo'd and going to landfill), but with a new finish. My question is whether or not these areas might contribute to this credit. On the one hand, it seems like this fulfills part of this credit (keeping material out of the landfill), while on the other, it does add new embodied energy to the project. Thoughts? Thank you.
