2. Materials and Resources Overview LEED materials and resources • Material choices are extremely important in reducing environmental impact • Construction and demolition of spaces make up approx. 40% of the total solid waste in the US • Sustainable material choices can make a significant environmental change • Material content is a major portion of commercial interior projects because of building materials and furnishings • Alternative material choices/options include: • Reuse • Ex: Rehabilitating an existing structure; Specifying salvaged materials in construction documents • Results in less habitat disturbance and less infrastructure • Recovery • Taking construction debris and recycling the materials • Salvaged Materials • Substitute for new materials; saves cost • Recycled-Content Materials • Reuse of waste products that would otherwise go into landfills • Local Materials • Rapidly Renewable Materials • Minimize natural resource consumption/depletion • Because furniture comprises a major part of the materials within a project, every furnishing should be included in calculating for LEED - CI certification • LEED Prerequisites and Credits: • MR Prerequisite 1, MR Credit 1.1, MR Credit 1.2, MR Credit 1.3, MR Credit 2.1, MR Credit 2.2, MR Credit 3.1, MR Credit 3.2, MR Credit 3.3, MR Credit 4.1, MR Credit 4.2, MR Credit 5.1, MR Credit 6.1, MR Credit 7 ***MR stands for Materials and Resources

3. MR Prerequisite 1 - Storage and Collection of Recyclables Overview LEED materials and resources • Intent: • Facilitate the reduction of waste generated by building occupants that is hauled to and disposed of in landfills • Requirements to Meet Prerequisite: • Provide an easily accessible dedicated area that serves the tenant space for collection and storage of materials for recycling • Must collect and store paper, corrugated cardboard, glass, plastics, and metals at the very minimum • Submittals: • Provide LEED-CI Template, signed by the architect, interior designer, and tenant or landlord, declaring that the area dedicated to recycling is easily accessible and accommodates the tenant’s recycling needs. • Provide a plan showing the area(s) dedicated to collection and storage of recycled materials, or a letter from the landlord outlining the building’s recycling plan. • Potential Technologies and Strategy Recommendations: • Make designated space appropriately sized and in convenient location • Identify local waste handlers and buyers for glass, plastic, metals, office paper, cardboard, organic waste, etc. • Educate/Instruct occupants on the building’s recycling procedures • Consider technology to make the recycling program easier and more effective • Ex: Cardboard Balers, Aluminum Can Crushers, Recycling Chutes • Credit Interpretation Rulings: • LEED-CI projects that occupy less than a full building do not necessarily need to provide an outdoor collection area if one is provided to all building occupants or when the material hauler or landlord makes pick ups within the tenant space.

4. MR Prerequisite 1 - Approach and Implementation LEED materials and resources • Strategies: • Determine the extent of services available in the area • Ex: Local waste handlers, buyers for glass, plastic, metal, etc. • Determine the services offered by the building owner • Confirm building-wide recycling plan meets requirements of the prerequisite if one is already in place (size, accessibility, etc.) • In the Design Phase: • Designate well-marked and size appropriate collection and storage areas for recycled materials (I.e. office paper, cardboard, glass, plastic, etc.) • Make collection area centrally located and easily accessible for collection vehicles (usually the ground floor) • Provide instruction for occupants and maintenance staff on recycling procedures • The Area Approach to Recycling: • Voluntary method in LEED-CI (adherence to guidelines NOT required) • Seattle passed and ordinance requiring minimum areas for collection and storage of recyclables in commercial and residential buildings • Minimum recycling area is based on the total square footage of the building • The Occupancy Approach to Recycling: • Voluntary method in LEED-CI (adherence to guidelines NOT required)

5. MR Prerequisite 1 - Submittal and Considerations LEED materials and resources • LEED-CI Documentation Submittal Requirements: • LEED-CI Letter Template declaration requires confirmation that the minimum paper, corrugated cardboard, glass, plastics, and metals are collected • Include a floor plan showing location and size of of area or provide letter from the landlord discussing the recycling program and how it meets the requirements • If audited, additional documentation such as calculations used in determining the storage area or correspondence with the building owner may need to be supplied • Issues to Consider and Remember: • Environmental Issues: • Recycling materials reduces needs to consume virgin natural resources (recycling 1 ton of paper prevents the processing of 17 tress) • Reduces solid landfill deposits (recycling 1 ton of paper saves 3 cubic yards of landfill space) • Economic Issues: • Improves land, water, and air quality • Initial cost for recycling = minimal • Long-term savings = high (no bill for landfill disposal costs, etc,) • Negative - recycling area uses space that could otherwise be used for something else (implementing technologies like can crushers can help minimize required space) • Community Issues: • Many Communities support and sponsor recycling programs; this generates significant amounts of valuable resources to be returned to the production process which can boost employment and preserve existing habitat areas within the community • Consider IEQ (Indoor Environmental Quality) - recycling activities that create noise, odors, or air contaminants should be isolate or done during non-occupant hours • Adding space for collection and storage can raise cost and increase project footprint

6. MR Credit 1.1 - Tenant Space Overview and Implementation LEED materials and resources • Intent: • Encourage choices that will conserve resources, reduce waste, and reduce the environmental impacts of tenant as they relate to materials, manufacturing and transport • Requirements to Qualify for Credit: • Occupant commits to remain in the same location for no less than 10 years • Submittals: • Provide LEED-CI Template, signed by the building owner or other responsible party, declaring that the occupant either owns its space or has signed a lease for no less than 10 years • Potential Technologies and Strategy Recommendations: • Suggest negotiations resulting in longer leases or ownership • Satisfying the Requirements: • Project area must be either owned by the occupant or is currently in a lease with a term of no less than 10 years • Condominium ownerships can be used toward this credit • There are no stipulations regarding the start of the lease period and the project construction activities or temporary relocations of occupant during the construction • Total Points Earned Upon Satisfying Requirements: 1

7. MR Credit 1.1 - Submittal and Considerations LEED materials and resources • LEED - CI Documentation Submittal Requirements: • LEED -CI Letter Template requires declaration that the occupant either owns the space or currently has a least with a term of no less than 10 years. • Type of commitment must be indicated - either ownership or leaseholder • Project team should maintain documentation of the lease agreement in a leased space during the submittal review process • Issues to Consider and Remember: • Environmental Issues: • Ownership or long-term lease reduce the need and frequency for relocation and the materials and construction activities associated with that relocation • Longer-term leases generate greater return on energy efficiency • Community Issues: • Longer-term tenancy entices employees to reside, shop, and enjoy their communities, which helps improve the area

8. MR Credit 1.2 - Building Reuse: Maintain 40% of Interior Non-Structural Components LEED materials and resources • Intent: • Extend the life cycle of existing building stock, conserve resources, retain cultural resources, reduce waste and environmental impacts of new buildings as they relate to materials manufacturing and transport • Requirements to Qualify for Credit: • Must maintain at least 40% (by area) of the existing non-shell, non-structure components • Ex: Walls, Floorings, Ceilings • Submittals: • Provide LEED-CI Letter Template, signed by the architect, interior designer, owner or other responsible party, listing the all the retained elements and declaring that the credit requirements have been met • Potential Technologies and Strategy Recommendations: • Identify the potential to maintain as many of the existing interior elements as possible during the selection and design phase of the tenant space • Remove any elements that pose contamination risk to occupants • Update outdated components • Quantify the extent of reuse • Total Points Earned Upon Satisfying Requirements: 1

9. MR Credit 1.3 - Building Reuse: Maintain 60% of Interior Non-Structural Components LEED materials and resources • Basically the same as MR Credit 1.2 - Building Reuse ---Only difference is maintain 60% instead of 40% • Intent: • Extend the life cycle of existing building stock, conserve resources, retain cultural resources, reduce waste and environmental impacts of new buildings as they relate to materials manufacturing and transport • Requirements to Qualify for Credit: • Must maintain at least 40% (by area) of the existing non-shell, non-structure components • Ex: Walls, Floorings, Ceilings • Submittals: • Provide LEED-CI Letter Template, signed by the architect, interior designer, owner or other responsible party, listing the all the retained elements and declaring that the credit requirements have been met • Potential Technologies and Strategy Recommendations: • Identify the potential to maintain as many of the existing interior elements as possible during the selection and design phase of the tenant space • Remove any elements that pose contamination risk to occupants • Update outdated components • Quantify the extent of reuse • Total Points Earned Upon Satisfying Requirements: 2 • One point is received for satisfying MR Credit 1.2 (Building Reuse - Maintaining 40%) and another point is earned for satisfying MR Credit 1.3 (Building Reuse - Maintaining 60%)

10. MR Credit 1.2 and 1.3 - Rulings and Objectives LEED materials and resources • Credit Implementation Rulings: • In LEED-CI, MR Credit 1.2 and MR Credit 1.2 only address non-structural interior components • Fixed items (I.e. doors, walls) found on-site are included int his credit and count toward the % of reuse when reused for the same function • Ex: a door is reused again as a door • If the fixed item found on-site is used for a purpose other than its original intent, it counts towards earning MR Credit 3.1 and MR Credit 3.2 • Ex: using a door to make a table • Even if not reused, area for these objects must be included in the prior condition area calculation of MR Credit 1.2 and MR Credit 1.3 • Full-height wall systems are not included in MR Credits 1.2 and 1.3 • Division 12 items (I.e. furniture and furnishings) are addressed in MR Credit 3.3 • MR Credit 1.2 and 1.3 Objectives: • Recognizing the importance of selecting a space where the existing interior aligns with the anticipated used • Recognizing when the design and construction of the space successfully maintain the existing interior construction • Accomplish these objectives by basing the % on the larger of the following areas: • The area of components in the prior condition • The area of components in the completed design

11. MR Credit 1.2 and 1.3 - Implementation and Submittals • Strategies: • Develop the architectural program prior to selecting the project space • Use the program to match the anticipated needs for the enclosed spaces with those in potential buildings under consideration • Planning: • Once the final space is selected and prior to any demolition, the project team should inventory the prior conditions • Develop a floor plan showing the location of finished ceilings, floorings, interior wall partitions, doors within the interior walls, exterior and party walls, and exterior windows and doors • Document any built-in goods that will be reused • Drawings should provide all the detail necessary to determine that surface area of all these components • Construction Phase: • Confirm that the item designated for reuse can, indeed, be reused • LEED-CI Documentation Submittal Requirements • Must submit the LEED-CI Letter Template with a table that matches Table 1 (Addressed in Next Slides) • Additional documentation may be requested demonstrating credit achievement; this can include 2 distinct plans: • Plan documenting the prior condition • Final plan showing where the retained components are located • ***Periodic progress photos starting prior to demolition and taken through occupancy are ideal means fo confirming performance on MR Credits 1.2 and 1.3 • Exemplary Performance: • An Innovation in Design point for exemplary performance may be earned when the requirements reach the next incremental step (for Building Reuse Maintain Interior Non-Structural Components, this means 80% or grater must be reused to the the Innovation in Design Point) LEED materials and resources

12. MR Credit 1.2 and 1.3 - Calculations • Quantity of Finished Area: • Credits MR 1.2 and 1.3 are based on surface areas, which include finished ceilings, walls, doors, flooring, and built-ins • For walls, determine the finished area between the floor and ceiling • For interior wall partitions and doors, count the area of both sides ; For exterior and part walls, count only one side • Subtract the area of exterior windows and exterior doors from both the prior conditions and completed design totals • For Built-in case goods, determine the finished area • Prior Condition Calculations: • Determine the total finished areas that existed prior to the start of the project and any demolition • If ceiling is exposed both prior to construction and in the final design, include this area in both • If there was a lay-in ceiling prior to construction but not after, include the ceiling area in the oth the prior condition and completed design area, but not in the retained components area • Completed Design Calculations: • Determine the total finished area in the completed design including all new and retained elements • Retained Components Area Calculation: • When determining the retained components area, include only the surface area of ceilings, walls, interior doors, floors, and built-in case goods that were in the space both prior to construction and in the completed design • Be sure to include items that have been saved, but may have been relocated • Ex: full-height demountable walls and doors that were re-hung in a new section of wall • Items counted in MR Credit 1.2 and 1.3 are NOT to be included in LEED-CI MR Credit 3.1 or Credit 3.2 • Percent Maintained Calculation: • Complete Table 1(Example on next slide) and divide the Total Retained Components area into the larger of either the total Prior Condition Area or total Completed Design Area LEED materials and resources
