Can my new construction / major renovation or addition pursue LEED v4 ID+C?

There may be situations where an owner or tenant wishes to certify the interior space of a new construction project. This can include major renovations, and new additions. 

Generally, LEED ID+C should not be used to certify some or all of a new construction building where the interior fit-out is part of the same scope of work as the base building construction. Such projects should pursue LEED BD+C instead. However, if there is sufficient separation between the base building and interior fit-out, the project may be eligible for a separate ID+C certification. Examples might include where there are different project teams, timelines, and/or contracts etc., between the shell and interiors. 

Project teams should select the most appropriate option from the suite of available LEED rating systems, however, the 40/60 rule provides guidance when several rating systems appear applicable to a project. If more than 60 percent of the project’s gross floor area (GFA) will be new construction (including a mix of renovations and new additions), it would not be eligible for ID+C. 

Additionally, to pursue ID+C, at least 60 percent of the certifying interior GFA must be complete at the time of certification, whether new or existing. Furthermore, at least 40 percent of the GFA must be a renovation that includes furniture, furnishings and equipment (FF&E) intended for the functioning of the space (note that all areas within the LEED boundary must be included in credit calculations).
