In Table 1. Example Calculation for $500 office chair, the row “Wheels” in the column “Percentage of component meeting sustainability criteria” replace "5% with "10%" so the cell reads “10% postconsumer recycled content”

In Table 3. Calculating reuse for existing buildings and materials, in the row "Asbestos ceiling tiles (hazardous material removed) in the column "Existing area" replace text "13,250" with "0" or a dash. In row "Total" in column "Existing area" replace value "214,695" with "201,445" and in column "Percentage reused" replace value "66.6%" with "70.9%."

In the 3rd paragraph for BD+C and 2nd paragraph for ID+C replace the 4th-7th sentences with the following: "If optional products or materials are included in cost-based credit calculations, such as Option 2 under each Building Product Disclosure and Optimization credits, they must be included consistently across all cost-based credit calculations.

In the fourth paragraph, add in after "...at normal daily start times and at the minimum outside airflow rate.", "For projects with standardized identical construction, such as classrooms in a school or multifamily residential units, identify which rooms are identical in construction, finishes, configuration, square footage, and HVAC systems. For these scenarios, project teams can sample the identical spaces by testing one in seven."

In the fourth paragraph, add in after "...the greatest presumed contaminant source strength", "Determine the number of ventilation systems serving the building. Then, determine if the individual floor plates served by each single ventilation system are larger or smaller than 25,000 square feet. If they are smaller, take at least one sample for every 25,000 square feet, or fraction thereof, served by a single ventilation system. If they are larger, take one sample per floor plate.

Under Guidance, above step-by-step add:
At this time the additional inorganic contaminants and volatile organic compounds are not included in the human experience score. For a more comprehensive indoor air quality evaluation, projects are encouraged to include all or some of these additional contaminants in their measurements. An additional point under the Innovation credit is available for projects that include two additional contaminants.

Correct name of "Facility maintenance and Renovation" to "Purchasing - Facility maintenance and Renovation."

Add two bullets:
"Added/modified purchasing criteria under each option"
"Added new section for building materials"

Add the following bullet to the Required Documentation section:
- Description of collection, storage and disposal process for recyclable materials (including mixed paper, corrugated cardboard, glass, plastics, and metals), batteries and all lamps (indoor and outdoor, hard-wired and portable fixtures).

Revise the 3rd paragraph to read as:

"If actual weight cannot be measured, the waste quantity may be converted to weight using an appropriate volume to weight conversion factor. Facility-specific or regional conversion factors may be available. The EPA also publishes volume to weight conversion factors (see their document Volume-to-weight conversion factors for solid waste). Waste quantity estimates based on the amount of waste in the waste container must take into account how full the container is (as opposed to assuming the waste container is full).

Remove the following bullet points:
- requirements for storage locations for recyclable materials and batteries and lamps to MR prerequisite Waste Performance.
 Simplified ongoing consumables paper, toner cartridges, binders, and desk accessories to office supplies.
 Added new section for building materials

Updated and added the following bullet points:
 Tracking food and beverage purchases is now required in the policy for all projects.
 Moved lamps under electronic equipment.
 New requirements added for Interiors adaptation.
