acrylic with non paper backer

The credit calls for non paper faced backer board behind fiberglass enclosures. Does that apply to behind acrylic surrounds also?

Yes. LEED for Homes has always required use of non-paper-faced backer board in all shower/tub surround areas -- all of which have potential for leakage, yet typically have poor drying potential, leading to risk of mold and other moisture-related damage.
