Inquiry

The project is a 400,000 SF office building. The building structure and core spaces (stairwells, elevators, etc.) will remain. A new building envelope (skin) on the south and east elevations will be provided. Existing exterior walls will remain on the north and west elevation, with new insulation and windows. The majority of existing building systems will be replaced, with the following exceptions: - There are two existing chillers, one will be replaced and one will remain - Existing mechanical, storm, sanitary, and fire protection pipe risers will remain - The existing garage ventilation system will remain Since we are reusing the building structure, which limits some of our energy reduction strategies (building orientation, daylighting, etc.), and also salvaging existing exterior walls, mechanical equipment, and piping, we feel that we should qualify as an Existing Building Renovation. Please clarify if this assumption is correct.
