| MRp1 -Storage and Collection of Recyclables- Intention and Implementation |
|
Definition
Intention - Reduce waste from building occupants, reduce waste going to landfills, provide accesible storage locations on-site Implementation- a) Methods of Approach: separation, collection, and storage b) Collection sources: recycling chutes, collection bins, can crushers, cardboard balers c) Mandatory materials to be collected: glass, paper, metal, plastic, cardboards d) provide instruction to occupants e) encourage activities to promote recycling Note: there is NO required minimun area for the storage location for LEED, but the reference guide does offer "guidelines." The most important thing to understand is that the recycling area should be accessible and on-site

| MRc1.1 -Building Reuse- Intention and Implementation |
|
Definition
Intent - Extend the life cycle of existing building stock, conserve and retain cultural resources, reduce waste, reduce environmental impact with regards to manufacturing and transportation of materials Implementation - a) Reuse 75% of EXISTING building structure: 1) exclude - windows, doors, non-structural material, MEP (mechanical, electrical, plumbing), elevator equipment, any hazardous materials 2) include - flooring, framing, roof, exterior structure (envelope/shell) b) Calculations use square footage c) If addition to an existing building is more than 2 times the original, credits MR1.1+1.2 are NOT APPLICABLE. However, if this is the case, the materials can be used for MRc2.1+2.2 as waste diverted from disposal.

|
Definition
Intent - Extend the life cycle of existing building stock, conserve and retain cultural resources, reduce waste, reduce environmental impact with regards to manufacturing and transportation of materials Implementation - a) maintain 50% of EXISTING non-Structural Elements: 1) Exclude - MEP and elevator equipment 2) include - walls and partitions, doors, cielings, floor coverings b) Calculations use square footage Notes: If items like walls and doors (aka Fixed items) which are found onsite are used for the same purpose they were intentionally built for (i.e. a door is used again as a door), then they ARE counted toward this credit... If items are reused for something else (i.e. door is reused as a table), they are NOT counted toward this credit, but can count toward MRc3.1+3.2

| MRc3.1 -Materials Reuse- Intention and Implementation |
|
Definition
Intent - Reduce waste, Reduce processing of virgin resources and materials Implementation - a) 5% of all project materials (based on cost) is to be from salvaged, refurbished, & reused items: 1) materials do NOT need to come directly from project site. Any approved REUSE material is ok. 2) Include - beams, floors, posts, paneling, doors/frames, cabinetry, brick, and decorative items; Furniture may also be included only if it is included consistently through MRc3.1-7 3) Exclude - Recycled Items (addressed in MRc4.1-4.2), MEP (mechanical electrical plumbing), and elevator equipment b) Calculations based on COST (cost of reused materials/total materials cost) Notes1: There are two ways to determine the total materal cost (which will be used throughout the LEED process and you should know for the exam). Whichever option is chosen must be used consistently throughout all of the LEED credits. 1) Option 1: (45% rule) - use 45% of the total construction cost 2) Option 2: Use ACTUAL materials cost, benefit would be that if the actual material cost was less than the default 45% of construction cost, it would be easier to achieve the 5-10% thresholds. Notes2: Materials counted toward MRc3 can not be counted toward MRc1,2,4,6,7 |

| MRc4.1 -Recycled Content- Intention and Implementation |
|
Definition
Intent - Reduce impact from extraction and processing of virgin materials, Increase the use of recycle content in buildings Implementation - a) 10% of Total Materials Cost is to be from recycled content b) There are two types of recycled material: 1) Post Consumer - material that has already been used and will be reused for another application (plastic, paper, metal) 2) Pre Consumer - material from the manufacturer that has NOT been used and will NOT be reused (sawdust, flyash) c) Post consumer materals can count fully toward this percentage, while only half of the pre consumer materal can count d) Calculation of percentage based on COST e) For materials or items that are PARTLY made up of recycled content, the amount of recycled content is calculated by weight f) Include anything except MEP (mechanical electrical plumbing) and elevator equipment: 1) furniture may be included only if it is included consistently through MRc3.1-7 2) For steel products with no information available, we can assume 25% post consumer recycled content

Intent - Increase demand for building materials and products that are extracted and manufactured within the region. This supports indigenous resources and reduces environmental impacts from transportation. Implementation - a) 10% of Total Material Costs to be from extracted, processed, AND manufactured material within 500 miles of construction site b) Calculation of percentage based on COST c) For materials or items that are PARTLY made up of regional materials, the amount of regional material content is calculated by weight d) Include anything except MEP (mechanical electrical plumbing) and elevator equipment, Furniture is included provided it is included consistently in MRc3.1-7. e) Reused and salvaged materials that satisfy the requirements of MRc3.1-3.2 may also count toward MRc5.1-5.2 ... this is the only synergy with materials counted toward MRc3.1-3.2 |

| MRc7 -Certified Wood- Intention and Implementation |
|
Definition
Intent - Encourage and support forest management through the use of certified wood Implementation - a) 50% of new wood materials and product cost are required to be certified in accordance with the FSC's (forest stewardship council) Principles and Criteria for wood building components: Framing, flooring and subflooring, wood doors, etc. b) calculation of percentage based on COST (of total new wood material cost): 1) for materials or items that are PARTLY made up of certified wood materials, the amount of wood is calculated as a percentage of the total weight, volume, or cost. c) Exclude: 1) MEP (mechanical electrical plumbing) and elevator equipment 2) the value of any recycled wood fiber content of a product that counts toward MRc4 since the calculations for this credit only deal with NEW wood products
d) furniture is ok to be used in this calculation providing consistency in MRc3-7 e) Wood vendors which invoice FSC-certified wood products to contractors and subcontractors must be COC certified (chain-of-custody) by an FSC-accredited certifier. Contractors and subcontractors do not need COC certification.
