 Sustainable Construction

Sustainable Construction is a subset
 of sustainability, which focuses
 more on the built environment,
 both during the construction phase
 and during the operational life
 cycle of the facility.
Green Building is a very common
 term used as a major focus area in
 sustainable construction

MATERIALS REUSE                     (MRc3)
 Use salvaged, refurbished or reused
  materials to reduce demand for virgin
  materials and reduce waste, thereby lessening
  impacts associated with the extraction and
  processing of virgin resources.

 Core materials that may be eligible include
  salvaged brick, structured timber, stone,
  pavers.

 Confirm that they do not contain toxic
  substances, such as lead or asbestos.
MATERIALS REUSE (MRc3)
 Refurbished materials are products that could have
  been disposed of as solid waste. These products have
  completed their life cycle as consumer items and are then
  refurbished for reuse without substantial alteration of their
  form. Refurbishing include renovating, repairing,
  restoring, or generally improving the appearance,
  performance, quality, functionability, or value of a product.

 Remanufactured materials are items that are made into
  other products. One example is concrete that is crushed
  and used as subbase.

 Salvaged materials or reused materials are
  construction materials recovered from existing buildings or
  construction sites and reused. Common salvaged
  materials include structural beams and posts, flooring,
  doors, cabinetry, brick and decorative items.

       Recycled Content

 MR Credit 4.1:
  10% (post-consumer +
        ½ pre-consumer)
 MR Credit 4.2:
  20% (post-consumer +
        ½ pre-consumer)
Materials & Resources Credit 4:
        Recycled Content
 Identify the percentage of
 postconsumer and/or preconsumer
 recycled content by weight, and list
 the recycled information source. LEED
 requires that the information be from
 a reliable, verifiable source.

 Distinguish between postconsumer
 and preconsumer recycled content.
Materials & Resources Credit 4:
        Recycled Content
 Post-consumer material – waste
 material generated by households or by
 commercial, industrial & institutional
 facilities in their role as end-users of
 the product, which can no longer be
 used for its intended purposes

 Pre-consumer material – material
 diverted from the waste stream during
 the manufacturing process. Excluded is
 reutilization of materials such as
 rework, regrind or scrap capable of
 being reclaimed within the same
 process that generated it.
Materials & Resources Credit 4:
       Recycled Content

RC shall be defined in accordance
 with ISO 14021-Environmental
 labels and declarations - Self-
 declared environmental claims
 (Type II environmental labeling)
REGIONAL MATERIALS                 MRc5
 Indicate the distance between the
 project site and the manufacturer
 location, and the distance between
 the project site and the extraction
 site for each raw material in your
 product.

 Submit cutsheets that document
 material origin and manufacture
 within an 800-km radius of the
 project site.
Materials & Resources Credit 6:
 Rapidly Renewable Materials
Rapidly renewable building materials
 /products are made from plants
 that are typically harvested within
 a 10-yr cycle or shorter, such as
 bamboo, wool, cotton insulation,
 agrifiber, linoleum, wheatboard,
 strawboard and cork. They may
 also be animal-based.
MRc6:       Rapidly Renewable Materials
   Identify products that are considered
    rapidly renewable and their materials
    costs.

   Calculate the percentage of rapidly
    renewable materials.

   For Assembly Rapidly Renewable
    Content, the fraction of the assembly that
    is considered rapidly renewable is
    determined by weight. That fraction is
    then applied to the materials cost to
    determine the rapidly renewable materials
    cost for that assembly.
MRc6:       Rapidly Renewable Materials
        Documentation Guidance
   Compile a list of rapidly renewable
   product purchases.
   Record manufacturers’ names,
   materials costs, the percentage of each
   product that is rapidly renewable
   criteria (by weight), and each compliant
   value.
   Retain cutsheets to document rapidly
   renewable criteria.
   Maintain a list of actual materials
   costs.

        Certified Wood
Certified Wood
 – wood products which are made
 from wood that has been grown
 and processed in a manner that is
 environmentally friendly
 - certified in accordance with the
 Forest Stewardship Council’s (FSC)
 Principles and Criteria. FSC-
 certified products have a Chain-of-
 Custody (CoC) certification.
MRc7:                                Certified Wood
  Chain-of-Custody (COC) Requirements
   Collect all vendor invoices for permanently installed
    wood products, Forest Stewardship Council (FSC)
    certified or not, purchased by the project contractor and
    subcontractors.
  Each vendor invoice must conform to the
    following requirements:
   Each wood product must be indentified on a line-item basis.
   FSC products must be identified as such on a line-item basis.
   The peso value of each line item must be shown.
   The vendor’s COC certificate number must be shown on any
    invoice that includes FSC products.
  Each wood product’s vendor that invoices FSC
    certified product must be COC certified by an
    FSC-accredited certifier.
MRc7:                               Certified Wood
  Comply with the following requirements, if the wood
    products are FSC certified:
   The vendor’s COC number must be shown on the invoice.
   The invoice must be supplemented by a letter from the
    vendor stating that the products invoiced are FSC certified.
   The invoice or the letter must state whether the products
    are FSC pure, FSC Mixed Credit or FSC Mixed (NN) %.
  Calculations
   List all new wood products (not reclaimed, salvaged or
    recycled) on the project.
   Identify which components are FSC certified.
   Tally the cost of all new wood products, both FSC certified
    and not.
   Calculate the amount of new wood and the amount of FSC
    certified wood permanently installed on the project.
    Develop a spreadsheet.
   Determine the percentage of FSC certified wood.
MRc7:                            Certified Wood
  Assemblies
  In the case of manufactured products, such windows and
   furniture systems that combine wood and nonwood
   materials, only the new wood portion can be applied
   toward the credit.
   Determine the value of the wood component(s):
   Calculate the amount of new wood as a percentage of
     the total weight, volume, or cost, and the amount of
     FSC-certified wood as a percentage of the total weight,
     volume, or cost.
   Multiply these figures by the total value of the product
     as invoiced to project contractors, subcontractors, or
     buying agents.
   Develop a separate spreadsheet for each assembly to
     calculate the amount of new wood and amount of FSC-
     certified wood for assemblies and enter the summary
     data as 1 line item on the comprehensive spreadsheet
     used to calculate the percentage of certified wood used
     in the project.
MRc7:                              Certified Wood
  Documentation Guidelines
  As a first step in preparing to complete the LEED-Online
  documentation requirements, work through the following
  measures. Refer to LEED-Online for the complete
  descriptions of all required documentation.
   Track certified wood purchases and retain associated
    COC documentation.
   Collect copies of vendor invoices for each certified wood
    product.
   Maintain a list that identifies the percentage of certified
    wood in each purchase.
