Sustainable purchasing - facility alterations and additions

MRc3 | Possible 1 point

Intent

To reduce the environmental and air quality impacts of the materials acquired for use in the upgrade of buildings.

Requirements

Maintain a sustainable purchasing program covering materials for facility renovations, demolitions, refits and new construction additions. This applies only to base building elements permanently or semipermanently attached to the building itself. Examples include, but are not limited to, building components and structures (wall studs, insulation, doors, windows), panels, attached finishings (drywall, trim, ceiling panels), carpet and other flooring material, adhesives, sealants, paints and coatings. Materials considered furniture, fixtures and equipment (FF&E) are not considered base building elements and are excluded from this credit. Mechanical, electrical and plumbing components and specialty items such as elevators are also excluded from this credit.

A template calculator for MR Credit 3 is available in the LEED for Existing Buildings: Operations & Maintenance Reference Guide. One point is awarded to projects that achieve sustainable purchases of 50% of total purchases (by cost) during the performance period. Sustainable purchases are those that meet one or more of the following criteria:

  • Purchases contain at least 10% postconsumer and/or 20% postindustrial material.
  • Purchases contain at least 70% material salvaged from off-site or outside the organization.
  • Purchases contain at least 70% material salvaged from on-site, through an internal organization materials and equipment reuse program.
  • Purchases contain at least 50% rapidly renewable material.
  • Purchases contain at least 50% Forest Stewardship Council (FSC)–certified wood.
  • Purchases contain at least 50% material harvested and processed or extracted and processed within 500 miles of the project.
  • Adhesives and sealants have a VOC content less than the current VOC content limits of South Coast Air Quality Management District (SCAQMD) Rule #1168, or sealants used as fillers meet or exceed the requirements of the Bay Area Air Quality Management District Regulation 8, Rule 51.
  • Paints and coating have VOC emissions not exceeding the VOC and chemical component limits of Green Seal’s Standard GS-11 requirements.
  • Noncarpet finished flooring is FloorScore-certified and constitutes a minimum of 25% of the finished floor area.
  • Carpet meets the requirements of the CRI Green Label Plus Carpet Testing Program.
  • Carpet cushion meets the requirements of the CRI Green Label Testing Program.
  • Composite panels and agrifiber products contain no added urea-formaldehyde resins.

Composite wood and agrifiber products are defined as particleboard, medium-density fiberboard (MDF), plywood, oriented-strand board (OSB), wheatboard, strawboard, panel substrates and door cores.

Each purchase can receive credit for each sustainable criterion met (i.e., a $100 purchase that contains both 10% postconsumer recycled content and 50% of content harvested within 500 miles of the project counts twice in the calculation, for a total of $200 of sustainable purchasing).

Materials for alterations or additions must be purchased during the performance period to earn points in this credit.
