To reduce the environmental and air quality impacts of the materials acquired for use in the operations and maintenance of buildings.
Maintain a sustainable purchasing program covering materials with a low cost per unit that are regularly used and replaced through the course of business. These materials include, but are not limited to, paper (printing or copy paper, notebooks, notepads, envelopes), toner cartridges, binders, batteries and desk accessories but exclude food and beverages (see MR Credit 5). For materials that may be considered either ongoing consumables or durable goods (see MR Credit 2), the project team is free to decide which category to put them in as long as consistency is maintained with MR Credit 2, with no contradictions, exclusions or double-counting. Consistency must also be maintained with MR Credit 7.
A template calculator for MR Credits 1.1–1.3 is available in the LEED for Existing Buildings: OPERATIONS & MAINTENANCE Reference Guide. One, two or three points are awarded to projects that achieve sustainable purchases of at least 40%, 60% or 80%, respectively, 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 50% rapidly renewable materials.
- Purchases contain at least 50% materials harvested and processed or extracted and processed within 500 miles of the project.
- The purchases consist of at least 50% Forest Stewardship Council (FSC)–certified paper products.
- Batteries are rechargeable.
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).
Ongoing consumables must be purchased during the performance period to earn points in this credit.
