In the second paragraph under Step by Step Guidance, add the following language to the second sentence:
"(also known as “commingled” or “mixed materials” recycling rates),"

Add the following as the first bullet under Construction Waste Management Plan:
"Tracking: develop a method for tracking the amount of all waste and recyclable materials generated during demolition activities (if any), including demolition of existing buildings, other structures on the site, or components demolished as part of building renovation work. Separately, keep track of waste and recyclable materials generated during new construction activities."

In the third paragraph under Step 1, add the following as the last sentence:
"See the Exemplary Performance section for minimum criteria for eligible third-party verified recycling rate programs."

In Step 3, add the following as the last sentence:
" Develop a method for tracking the amount of all demolition materials generated on the project (if any). Separately, keep track of waste materials generated during new construction activities."

Delete the Waste Prevention section.

Add the following as a new section:

Option 2. Waste Prevention
Follow step-by-step instructions from the v4 Reference Guide with the following modifications:

Step 2: Calculate Total Waste Reduction

Projects can document waste prevention techniques undertaken on the project to earn 2 points. To calculate the project’s total waste, include all materials generated from the project construction and demolition activities and sent offsite for recycling, diversion, landfill, incineration, or any other uses. Exclude hazardous materials, land-clearing debris, and on-site reused materials from the generation numbers. A narrative, provided in the LEED form, must describe strategies in design and construction that were implemented to reduce waste from being generated on the jobsite (See LEED v4 reference guide, Further Explanation, Source Reduction for more guidance on source reduction strategies).

Tracking: To calculate waste prevention, project teams must track the amount of waste generated during demolition work and—separately—during new construction activities. For projects with demolition activities, including demolition of existing buildings, other structures on the site, or components demolished as part of building renovation work, develop a method for tracking the amount of all waste generated from demolition. To be eligible for Option 2, the project must demonstrate that at least 50% of the demolition waste was diverted (note: ADC does not count as diversion). Separately, keep track of waste generated during new construction activities. The amount of new construction-phase waste will be used to quantify the amount of waste generated (per ft2 or m2) for Option 2 credit compliance.

Reducing waste by thoughtful design results in the reduction of waste on the jobsite. Stopping waste before it is created is always higher priority than managing waste after construction. Successful projects have implemented the following strategies to prevent construction and demolition waste in LEED:

• Reuse buildings or building components. Materials that are reused onsite are excluded from the waste generation calculations. Sending materials offsite to salvage, donation or recycling, such as through a documented manufacturer take-back program, does not count as waste prevention but can count towards project diversion.
• Source reduction strategies should be incorporated into the design of the project and outlined in the Waste Management Plan. These strategies include reusing existing materials and components, designing for modular construction sizes and techniques, specifying reduced packaging from vendors, designing for industry-standard measurements, eliminating unnecessary finishes, and off-site prefabrication of components or assemblies.
• Work with subcontractors and/or finish material suppliers to eliminate or minimize packaging waste and reduce overall materials rather than send them for disposal or recycling. "

Revise the Exemplary Performance section to read as:
"Achieve Option 1 and Option 2."
