The LEED Rating System Evaluates Projects Over 5 Core and 1 Bonus Credit Categories:

Overview of LEED Programs
The LEED Rating System originated as a program designed to evaluate new construction and major renovations for office buildings. With the success of this initial system the USGBC created several other LEED products to address other project types not covered by the original rating system.

LEED-NC (New Construction & Major Renovations) Version 2.2 Released 2005
LEED-NC is designed to be applied to Commercial and Institutional buildings that are either new or undergoing major renovations with a focus on office buildings. Practitioners have also applied the system to K-12 schools, multi-unit residential buildings, manufacturing plants, laboratories and many other building types. LEED-NC Version 2.2 was released in late 2005.

LEED-CI (Commercial Interiors) Released 2004
LEED-CI is designed to address the specifics of tenant spaces primarily in office and institutional buildings. LEED-CI provides the opportunity for building tenants to design and certify high performance, healthy, durable, affordable and environmentally sound workplaces.

LEED-EB (Existing Buildings) Released 2004
LEED-EB is designed to be a set of performance standards for the sustainable operation of existing buildings. It includes building operations and upgrades of systems and/or processes in existing buildings where these upgrades do not significantly change the interior or exterior surfaces of the building.

LEED-CS (Core & Shell Development) Project Release 2005
LEED-CS is a set of performance standards for the sustainable design and construction of speculative and core-and-shell buildings. Based on the LEED-NC Rating system, LEED-CS has been developed in recognition of the unique nature of core and shell development, especially the lack of developer control over key aspects such as interior finishes, lighting, and HVAC distribution. LEED-CS is designed to complement the LEED-CI Green Building Rating System so that a LEED-CS certified building that also incorporates a LEED-CI certified interior fit-out will be the equivalent to a LEED-NC certified building.

Recycled Content

Credit 4.1 Recycled Content:
10% (post-consumer + 1/2 pre-consumer) (1 Point)

Credit 4.2 Recycled Content:
20% (post consumer + 1/2 pre-consumer) (1 Point in addition to 4.1)
Note: pre-consumer recycled content has the same meaning as post-industrial.

Increase demand for building products that incorporate recycled content materials, thereby reducing impact resulting from extraction and processing of new virgin materials.

Use materials with recycled content such that the sum of post-consumer recycled content plus one-half of the pre-consumer content constitutes at least 10% or 20% of the total value of the materials in the project.

The value of recycled content portion of a material or furnishing shall be determined by dividing the weight of recycled content in the item by the total weight of the material in the item, then multiplying the resulting percentage by the total value of the item.  Recycled content shall be defined in accordance with the International Organization of document, ISO 14021—Environmental labels and declarations—self-declared environmental claims (Type II environmental labeling).

LG Eden Collection Credit Contribution

All of the LG Eden collection recycled colors contain a minimum of 12% pre-consumer content.  All of these colors have third party certification by SCS.  Two simple generic calculation examples
are noted below which are to be combined with all other project materials to come up with the
final percentage:

Equation 1:
Recycled [$] Content Value =  Material or [$] Product cost  x  Recycled [%] Content

Equation 2:
Recycled [%] Content Rate = Post-consumer RCV [$]  +  1/2 Pre-consumer RCV [$]
                                                                        Total Materials Cost [$]
Note: RCV = Recycled Content Value

Surfacing Product Calculation

Total Materials Cost:      $2,000,000
LG Eden Cost:                $60,000
Recycled Content:         12% Pre-consumer
Post Industrial RCV:       $60,000 x 12% = $7,200

Recycled Content Rate: Post-consumer RCV  +  1/2 Pre-consumer RCV
                                                     Total Materials Cost [$]

Calculation:                 $0 PC RCV  +  1/2  [$7,200]    =    $3,600    =  .18
                                             $2,000,000                $2,000,000

Regional Materials

Credit 5.1 Regional Materials: 
10% Extracted, Processed & Manufactured Regionally  (1 Point)

Credit 5.2 Regional Materials:
20% Extracted, Processed & Manufactured Regionally  (1 Point in addition to 5.1)

Increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the regional economy and reducing the environmental impacts resulting from transportation.

Use building materials or products that have been extracted, harvested, or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% or 20% (based on cost) of the total materials value.  If only a fraction of a product or material is extracted/harvested/recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value.


LG Eden Collection Credit Contribution

This contribution must be calculated for every project location.  The LG Eden Collection is manufactured in Calhoun, GA 30701.

Equation 1:
Regional [%] Materials Rate  =  Regionally Extracted, Processed & Manufactured Materials Cost [$]
                                                 Total Materials Cost [$]


ID Credits 1-4: Innovative Design

LG Eden Collection Potential Contributions
Designing assemblies from the LG Eden Collection Solid Surface materials can help reduce waste by custom sheet sizes allowing for less seams, labor and waste.  The durable LG Eden material also provides great opportunity for modular designs that can easily be deconstructed and relocated
and reused.


Other Potential Contributions

Resource Credits
The LG Eden Collection products are warranted for 15 years and most installations last well beyond the warranty.  Because of the exceptional life cycle of this product, many installations can be removed and reshaped for new locations.  This creates the possibility for Materials Reuse credits noted below:

MR Credit 3.1-NC-Versions 2.1 & 2.2: Materials Reuse-5%  (1 Point)
Note: Also see LEED CI: MR Resource Reuse Credit 3.1 5%, Credit 3.2 10%

Reuse building materials and products in order to reduce demand for virgin materials and to reduce waste, thereby reducing impacts associated with the extraction and processing of virgin resources.

Use salvaged, refurbished or reused materials such that the sum of these materials constitutes at least 5% based on cost, of the total value of materials on the project.

MR Credit 3.2 NC Versions 2.1 & 2.2: Materials Reuse-10% (1 Point-in addition to MR 3.1)

Reuse building materials and products in order to reduce demand for virgin materials and to reduce waste, thereby reducing impacts associated with the extraction and processing of virgin resources.

Use salvaged, refurbished or reused materials for an additional 5% beyond MR Credit 3.1 (10% total, based on cost).
