15-1112 v3.X Sourcing Location for Salvaged Materials


For the NRDC's San Francisco Office Renovation, we made many design decisions that involved reusing the existing materials in the space. To name a few, we are consciously reusing lights, wood and aluminum doors, ceiling panels, metal-grate steel supports, office fronts’ glazing and aluminum, many existing walls, exposed concrete/stone flooring, etc. rather than buying new products. The doors are being taken just off site to be retrofitted with slight alternations but everything else is remaining on site. These will all be documented as salvaged materials and can be supported with the demo and construction drawings. These efforts were taken not only for cost savings but to intentionally reduce the carbon footprint from extraction, manufacturing and transportation. We are requesting that the project site is considered the sourcing location for these items and therefore they will automatically fall within 500km. While we are attempting to source as many materials as we can locally, we have found it challenging to find manufacturers of many products within 500km of San Francisco. This would help us to meet this sourcing requirement, while also rewarding the reuse that we are highlighting in the project.


The salvage of existing materials in a renovation project reduces product transportation and the project's carbon  footprint related to the extraction and manufacture of new materials. The Institute recognizes the environmental benefits of increased material reuse and is creating an Exception for the tracking of in situ materials in major renovation projects.

I13-E1 In Situ Salvaged Materials
Major renovation (i.e. "gut rehab") projects under the Building or Renovation Typologies may track some in situ reused materials for I-13, Living Economy Sourcing. In situ salvaged materials may represent up to 10% of the project materials construction budget based on the estimated replacement cost of these materials. Only materials that are usually removed under typical renovation scopes of work may be included as salvaged. For example, interior partitions, millwork, interior doors, and ceiling, wall and floor finishes left in situ may be tracked as sourced onsite. Structural elements, exterior envelope, and base building systems are not considered within the typical scope of a renovation project and should not be tracked for Living Economy Sourcing. In situ items do not count as salvaged for I-14 Net Positive Waste.
