the grey area of sustainable purchases

These are good questions, Wendy. The key thing is that for any of the purchasing credits, you are required to track all purchases made during the performance period and then highlight those specific purchases which meet one or more of the LEED sustainability criteria. It's important to understand the LEED definitions of "Ongoing Consumables" and "Durable Goods" as well. Ongoing Consumables are products with a low cost per unit that are regularly used and replaced through the course of business. The LEEDUser Bird's Eye View for this credit does not mean to suggest that it is optional to track items other than paper, toner, binders, etc.; these are simply the basic categories of ongoing consumables that must be tracked at a minimum. There are many other types of ongoing consumables that are used on a regular basis in most commercial buildings that should be included in your tracking. Durable Goods are products that are available at a higher cost per unit and that are replaced infrequently and/or may require capital outlays. The simplest way to think about these types of products is to examine purchases of electronic equipment (including appliances) and furniture. So, to address your specific questions above: 1) items such as treadmills, keyboards, computer mouse, and speakers would fall under the Durable Goods category because they are electronic equipment with a higher cost 2) items such as first aid kits, periodicals, wrist pads, and keyboard trays could probably be considered Ongoing Consumables because they are low-cost items. Batteries are also considered ongoing consumables for LEED purposes. 3) "SWAG and gifts" is a bit trickier - ideally, the purchases you're tracking for these LEED credits are items that are being purchased for use within your project building. If you're buying items for clients, you can probably exclude them; likewise, if you're receiving these items from clients or trade shows, they are not being purchased by the project team, so they may also be excluded. In a nutshell, make sure you're tracking all items that are purchased by building management or staff that are intended for use in the project building during the performance period. Make sure you understand the sustainability criteria and use a consistent methodology to report all the products that meet those criteria .
