My team has just taken on a renovation/fit-out project. The building in which the project will take place is brand new, and is about 4 weeks from construction completion. It was pursuing LEED NC, but the use of the building changed abruptly from industrial testing to office and will require demolition and renovation that were not part of the original design and LEED package. Credits were not been submitted. As part of the new design team, I am working to determine the best path. 1) Can the project still pursue the original LEED NC, just with an added demolition/renovation phase? 2) Would it work better to split the project in two and certify the Core and Shell (original construction) and then use Commercial Interiors for the fit-out (my team, new design). 3) Would the new project classify as major renovation and pursue a new LEED NC package? Any guidance is greatly appreciated. Thank you.
