2. MATERIALS AND RESOURCES
Introduction:
What materials are used, where they come from, how they are made, and how they are
disposed of are instrumental in determining how green a project is. Using more green
materials, including renewable materials, recycled materials, and natural materials, is
good for the building occupants and the environment. LEED v4 shifts the focus a bit,
providing credits for using materials that have published life cycle assessments and
environmental product declarations.
Storage and Collection of Recyclables:
This is a required measure and must be completed to qualify for LEED certification.
Projects must provide space to allow for storage and collection of recyclables.
Materials collected must at least include paper, cardboard, glass, plastic, and metals.
The project must also make arrangements for the storage and collection of two of the
following: batteries, mercury-containing lamps, and electronic waste.
Construction and Demolition Waste Management Planning:
This is a required measure and must be completed to qualify for LEED certification.
The project must develop a waste management plan for use during demolition and
construction, and report on actual diversion rates for all debris leaving the site. At least
five materials must be targeted for recycling or reuse.
Building Life-Cycle Impact Reduction:
There are four options to achieve points:
(1) Reuse a building listed on a local or national historical register, following
requirements of the appropriate program for rehabilitation - 5 points.
(2) Renovate an abandoned or blighted building, maintaining at least 50% of the
existing structure and interior elements - 5 points.
(3) Re-use or salvage, from on the project site or off-project, building materials to
equal 25-75% of the surface area of the project - 25% for 2 points, 50% for 3 points,
75% for 4 points.
(4) Provide a life cycle assessment of the structure and enclosure, showing a
minimum of 10% reduction in at least three of six impact categories, including

3. MATERIALS AND RESOURCES
global warming potential, ozone depletion, and depletion of non-renewable energy
sources - 3 points.
Building Product Disclosure and Optimization - Environmental Product
Declarations:
Use at least 20 permanently installed building materials, from at least 5 different
manufacturers, that have had an environmental product declaration published
Use products certified as providing a reduction in environmental impact for at least
50% of the permanently installed materials. Products sourced within 100 miles of the
project site count at 200% of their cost.
Building Product Disclosure and Optimization - Sourcing of Raw Materials:
Use at least 20 permanently installed building materials, from at least 5 different
manufacturers, that have publicly released a report showing their extraction locations,
methods, and a commitment to sustainable extraction practices
Use materials, for at least 25% of the total material cost, that are: bio-based products,
FSC certified lumber, salvaged or reused, have recycled content, or have a producer
responsibility program. Products sourced within 100 miles of the project site count at
200% of their cost.
Building Product Disclosure and Optimization - Material Ingredients:
Use at least 20 permanently installed building materials, from at least 5 different
manufacturers, that have published reports showing the chemical content of the
material. The reports must be in the form of a manufacturer’s inventory, health product
declaration, or Cradle 2 Cradle certification
Use materials that have published reports through one of the following programs, for at
least 25% of the cost of the permanently installed materials: Green Screen
v1.2_Benchmark, Cradle 2 Cradle certified, or REACHES Optimization.
Use materials that have published reports documenting their safety and health practices
throughout the supply chain, for at least 25% of the cost of the permanently installed
materials.

Construction and Demolition Waste Management:
Using the waste management plan developed in the prerequisite, points are awarded for
meeting targets for the amount of material diverted from the landfill and that is
recycled or reused. 1 point is awarded for diverting 50% of the waste in at least three
waste streams (types). 2 points are awarded for diverting 75% of the waste in at least
four waste streams. Or a project cannot create more than 2.5 pounds of construction
waste per square foot of the building’s floor area for 2 points.
Storage and collection of recyclables:
Intent:
To facilitate the reduction of waste generated by building
occupants that is hauled to and disposed of in landfills.
Requirements provide a dedicated area for recycling for the
entire building. Materials must include, at a minimum: paper,
corrugated cardboard, glass, plastics and metals.
Building reuse: Maintain existing walls, floors, and roof:
Intent:
To extend the lifecycle of existing building stock, conserver sources, retain cultural
resources, reduce waste and reduce environmental impacts of new buildings as they
relate to materials manufacturing and transport.

5. MATERIALS AND RESOURCES
Maintain interior non-structural elements:
Intent:
To extend the lifecycle of existing building stock, conserve
resources, retain cultural resources, reduce waste and
reduce environmental impacts of new buildings as they
relate to materials manufacturing and transport.
Reuse 50% (by area):
Interior walls Doors
Floor coverings
Ceiling systems
Construction waste management:
Intent:
To divert construction and demolition debris from disposal in landfills and incineration
facilities. Redirect recyclable recovered resources back to the manufacturing process
and reusable materials to appropriate sites.

Materials Reuse:
Intent:
To reuse building materials and products to reduce demand for virgin materials and
reduce waste, thereby lessening impacts associated with the extraction and processing
of virgin resources.
Use only materials permanently installed, furniture may be included.

Recycled content:
Intent:
To increase demand for building products that incorporate recycled content materials,
thereby reducing impacts resulting from extraction and processing of virgin materials.

Regional Materials:
Intent
To increase demand for building materials and products that are extracted and
manufactured within the region, thereby supporting the use of indigenous resources
and reducing the environmental impacts resulting from transportation.

Regional Materials:
Strategies:
Locally sourced materials Identify materials & suppliers
Consider environmental, economic, and performance
ranges
Rapidly Renewable Materials: bamboo, wool, cotton, cork, straw board, wheat
board, agrifibre, linoleum.
Intent:
To reduce the use and depletion of finite raw materials and long-cycle renewable
materials by replacing them with rapidly renewable materials.

Understanding the crucial concepts of disclosure and optimization to ensure that
building materials are reused, purchased locally/sustainably, and have a low impact on
human and environmental health.
