What would you like to learn from this program?
USGBC & LEED for Green Buildings The U.S. Green Building Council's LEED green building certification system has transformed commercial building practices by providing the nation’s leading tool to create buildings that are environmentally and socially responsible, healthy and prosperous.
The influential program for the design, construction and operation of green buildings Over 36,000 commercial projects are
currently participating in LEED rating systems Comprising over 12 billion square feet of
construction space All 50 states 114 countries
LEED
The intent of LEED is to: Define “Green Building” by establishing common standard of
measurements Promote Whole Building
Design Recognize environmental
leadership in the building industry
Stimulate Green Competition
Raise Consumer Awareness of Benefits
Transform the Building Market

Interior Non-Structural Elements 1 ptNC S CI HC R
MRc4 – Recycled Content - 10% and 20% 1+1 ptNC CS S CI HC R
MRc5 – Regional Material - 10% and 20% 1+1 ptNC CS S HC R (CI gives 1 pt for local manufacturing and does not count extraction, harvest point until pt 2)
MRc6 – Rapidly Renewable 1 ptNC S CI HC R
MRc7 – Certified Wood 1 ptNC S CI HC R (MRc6 in CS)
MR Credit 1.2 NC|S|CI|HC|R
Building Reuse – Maintain Existing Interior Non-Structural Elements 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.
The longevity and durability of doors should allow re-use on LEED projects and help in the attainment of this credit.
Example: Stainless Steel Entry Door
MR Credit 4 NC|CS|S|CI|HC|R
Recycled Content Postconsumer recycled content
+ 1/2 pre-consumer content = 10-20% (based on cost) of the total
value of the materials in the project The recycled content value of a material
assembly is determined by weight. The recycled fraction of the assembly is then
multiplied by the cost of assembly to determine the recycled content value.
+ 1pt for Exemplary Performance 30%
Example: Stile & Rail Door
Wood Doors20-85%
MR Credit 5 NC|CS|S|CI|HC|R
Regional Material Intent to reduce environmental impact of
transportation Based on cost of material and then compared
to total cost of materials used in construction NC CS S must be Extracted, Processed (or
recovered), and Manufactured within 500 miles One additional point if over 20% (MR5.2)
CI allows 1 point if 20% material by cost is manufactured within 500 miles, second point if 10% is manufactured AND extracted, harvested or recovered
MR Credit 6 NC|S|CI|HC|R
Rapidly Renewable To reduce the use and depletion of
finite raw materials and long-cycle renewable materials by replacing them with rapidly renewable materials.
Use rapidly renewable building materials and products for 2.5% of the total value of all building materials and products used in the project, based on cost.
Rapidly renewable building materials and products are made from plants that are typically harvested within a 10-year or shorter cycle.
Certified Wood NC|S|CI|CS|HC|R|S
Certified Wood content value is determined by multiplying the certified wood content
fraction of the assembly (based on weight) by the cost of the assembly.
Note: Only virgin wood stock shall contribute towards the certified wood criteria. Certified wood shall not contribute to the rapidly renewable criteria.
All vendors, except those installing, that invoice FSC products must have a Chain of Custody (COC) number
Example: Stile and Rail Door, FSC Wood

Environmental Tobacco Smoke Control Prevent or minimize exposure of building
occupants, indoor surfaces and ventilation air distribution systems to environmental tobacco smoke (ETS).
Weather strip all wood doors in the residential units leading to common hallways to minimize air leakage.
Recommend specification of wood doors with perimeter gaskets and seals that have been tested in accordance with UL 1784-2001 Air Leakage Tests of Door Assemblies.
Example: Custom Sketch Veneer Door with Perimeter Gasketing
IEQ Credit 4.1 & 4.2 NC|CS|S|CI|HC|R
Low-Emitting Materials – Adhesives and Sealants, Paints & Coatings Reduce the quantity of indoor air
contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
This credit only applies to materials applied within the weatherproofing system however, pre-finished door and pre-installed glazing will allow LEED projects to avoid applying materials onsite.
Example: Integrated Door Opening Assembly
IEQ Credit 4.4 NC|CS|CI|S|HC|R
Low-Emitting Materials Composite Wood & Agrifiber Reduce the quantity of indoor air
contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
Composite wood and agrifiber products used on the interior of the building (i.e., inside the weatherproofing system) must contain no added urea-formaldehyde (NAUF) resins.
(S requires 1350 test, GREENGUARD, CHPS)
IEQ Credit 4.6 S|HC|R
Low-Emitting Materials Ceiling & Wall Systems Reduce the quantity of indoor air contaminants that are
odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.
All gypsum board, insulation, acoustical ceiling systems and wall coverings (including doors) installed in the building interior must meet the testing and product requirements of the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda (CA 01350).
May require GREENGUARD Indoor Air Quality certification or similar ,
IEQ Credit 5 NC|CS|S|CI|HC|R
Indoor Chemical & Pollutant Source Control Minimize building occupant exposure
to potentially hazardous particulates and chemical pollutants.
Sufficiently exhaust each space where hazardous gases or chemicals may be present or used (e.g., garages, housekeeping and laundry areas, copying and printing rooms)
For each of these spaces, specify closers on all wood door openings to provide self-closing wood doors.
Example: Stile and Rail Door with Gasketing and EAC
IEQ Credit 8.1/.2 NC|CS|S|CI|EBOM|HC|R
Daylight and Views To provide building occupants
with a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.
Adding glazing and sidelights to wood door openings will assist projects in achieving this LEED credit.
(IEQc.2.4 in EBOM)
Example: Privacy Sidelight with Opaque Glass
Indoor Environmental Quality HC|S|NC
IEQ Credit 9 Enhanced Acoustical Performance To provide classrooms that facilitates
better teacher-to-student and student-to-student communications through effective acoustical design.
Design the building shell, classroom partitions and other core learning space partitions to meet the Sound Transmission Class (STC) requirements of ANSI Standard S12.60-2002, Acoustical Performance Criteria, Design Requirements and Guidelines for Schools.
Example: Wood Veneer Door with Solid Core and Drop Seal
Indoor Environmental Quality SCredits specific to LEED for Schools IEQ Credit 10 – Mold Prevention
To reduce the potential presence of mold in schools through preventive design and construction measures.
Specify doors and hardware with anti-microbial coatings. Applied to doors and hardware Additional preventative
measure to assist school projects in achieving this credit.

Questions to Ask
What do you feel is better for the environment: a door produced from virgin lumber? or from a recycled or rapidly renewable material?
What strategy is being used for other products in the construction of the building?
Does the Wood Door Specification follow the same strategy as the rest of the building?
Facts
Hardwoods Forest increased by 90% in the last 50 years
Only FSC Certified Forests qualify for LEED at this time.
