LEED O+M: Existing Buildings | v2009

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 elements1 permanently or semipermanently attached to the building itself. 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 sample calculaton for this credit is available in the LEED Reference Guide for Green Building Operations & Maintenance, 2009 Edition. Achieve sustainable purchases of 50% of total purchases (by cost) during the performance period. Sustainable purchases shall meet 1 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 certified wood.
  • Purchases contain at least 50% material harvested and processed or extracted and processed within a 500 mile (800 kilometer) radius of the project. Building materials or products shipped by rail or water have been extracted, harvested or recovered, as well as manufactured within a 500 mile (800 kilometer) total travel distance of the project site using a weighted average determined through the following formula:
    (Distance by rail/3) + (Distance by inland waterway/2) + (Distance by sea/15) + (Distance by all other means) ≤ 500 miles [800 kilometers]

  • 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 meets one of the following requirements and constitutes a minimum of 25% of the finished floor area:
    • Is FloorScore certified

    • Maximum VOC concentrations are less than or equal to those specified in the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda, using the office scenario as defined in Table 7.5 within the practice.
    • Maximum VOC concentrations meet the California requirements specified above based on the following:
      • California Department of Public Health (CDPH) Standard Method V1.1-2010 using test results obtained at the 14 day time point

      • Projects outside the U.S. may use the German AgBB/DIBt testing method and all testing methods based on AgBB/DIBt method (GUT, EMICODE, Blue Angel) using test results obtained at the 3 day or 7 day or 14 day time point. For caprolactam, if test results obtained at the 3 day or 7 day time point is used, the emission concentration must be less than ½ of the concentration limit specified above because the emission may not have peaked at the measured time points.
        If a European testing method (AgBB/DIBt GUT, EMICODE, Blue Angel) had used parameters for calculating test results different from those specified in the referenced California method, then the European test results for carpets or floorings need to be converted into California air concentrations by multiplication with 0.7.
  • Carpet meets one of the following requirements:
    • Meets CRI Green Label Plus Carpet Testing Program

    • Maximum VOC concentrations are less than or equal to those specified in the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda, using the office scenario as defined in Table 7.5 within the practice. The additional VOC concentration limits listed in Section 9.1a must also be met
    • Maximum VOC concentrations meet the California requirements specified above based on the following:
      • California Department of Public Health (CDPH) Standard Method V1.1-2010 using test results obtained at the 14 day time point

      • Projects outside the U.S. may use the German AgBB/DIBt testing method and all testing methods based on AgBB/DIBt method (GUT, EMICODE, Blue Angel) using test results obtained at the 3 day or 7 day or 14 day time point. For caprolactam, if test result obtained at the 3 day or 7 day time point is used, the emission concentration must be less than ½ of the concentration limit specified above because the emission may not have peaked at the measured time points.
        If a European testing method (AgBB/DIBt GUT, EMICODE, Blue Angel) had used parameters for calculating test results different from those specified in the referenced California method, then the European test results for carpets or floorings need to be converted into California air concentrations by multiplication with 0.7.
  • Carpet cushion meets the requirements of the CRI Green Label Testing Program.
  • Composite panels and agrifiber2 products contain no added urea-formaldehyde resins.

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.
