Inquiry

We are requesting a credit interpretation for MR 1.2 (Maintaining 100% of the existing building structure and shell). The entire site structure and shell with the exception of an 1,800 square foot section of the roof deck has been maintained. As such, it appears that we qualify for MR Credit 1.1 (maintain 75% of existing building structure and shell). However, an approximately 1,800 square foot (30 ft. x 60ft.) section of the roof deck needed to be removed (existing structural supports remain in place) due to structural issues and to make way for a new monitor and PV array. Since only the roof deck was removed and the existing structural members remain, would this qualify for the MR 1.2 credit?
