We are doing a project where we are renovating the whole interior of an existing building but we are not renovating the exterior portion of the building. We are designing to LEED Healthcare New Construction Version 2009 in the interior portion of the project. Since we are not renovating the exterior of the building can I use the pilot credit for light pollution reduction SSpc7 for "Existing Building" or would I need to use the pilot credit for "Healthcare" since this is what we are designing to in LEED for the overall project?
