Architects can start using LEEDv4 prior to October of 2016
EPD's - The Scorecard
Environmental Product Declarations
Will allow an owner, architect or designer to take and compare a products environmental impact when shopping for similar products Cannot be completed without a Life Cycle Assessment (LCA) LCAs require a Product Category Rule (PCR) for the product to be developed and approved.
PCRs and LCAs
EPD's are a scorecard for a product that provides environmental impact information on such things as global warming potential and ozone depletion. According to LEED, "EPDs are independently verified reports that have been conducted to a set of common rules (PCRs) for each product category then peer reviewed."
Product Category Rule (PCR) comes first. It lays out the rules for a Life Cycle Assessment (LCA), allows for the comparison of similar products, follows ISO requirements and defines the scope, system boundaries and impacts of the LCA and EPD. The LCA determines the environmental impacts of a product throughout its life cycle. LCAs start with the extraction of raw materials, continue through the production of the product and product use and conclude with the disposal. It can evaluate which materials or processes throughout the production chain contribute to environmental impact categories such as global warming and ozone depletion.
The intent of this credit is to encourage the use of products and materials for which life-cycle information is available and have environmental, economical and socially preferable impacts.
SOURCING OF RAW MATERIALS
This credit references FSC, recycled content, biobased materials (i.e. agrifiber) and includes a location valuation factor.
Different components or ingredients within an assembled product may contribute to different credit criteria within this credit.
This is ONE credit (replacing MRc4, MRc5, MRc6 and MRc7 from LEED 2009) with the opportunity to double the dollar contribution to the credit if the distributor, manufacturer and the harvest location of the raw materials used in the product are within 100 miles of the jobsite.
FSC is still the only Forest Certification organization recognized by the USGBC. The investment made in FSC certification remains a good one.
The intent of this credit is to reward project teams for selecting products verified to have been extracted or sourced in a responsible manner.
What is a HEALTH PRODUCT DECLARATION ?
A standardized format for product contents, emissions and health information. Think of a HPD as a nutrition label for Building Products
The HPD Collaborative has developed a standard for developing a HPD but currently, there is not a process in place for validating the information on a HPD.
This credit is a disclosure of all chemicals and other ingredients found in a building product supplied for a project. LEED allows for manufacturers to use several methods for listing the inventory of materials found in their products with the most requested being the Health Product Declaration (HPD).
The intent of this credit is to reward project teams for selecting products for which the chemical ingredients are inventoried using an accepted methodology.
No Added Urea-Formaldehyde is no longer the criteria for composite wood products such as particleboard.
Doors need to be certified to the SCS Indoor Advantage Gold or GreenGuard Indoor Air Quality standards by the manufacturer to comply with this credit.
LEED now includes doors in the "Wall System" category, no longer "Composite Wood" category.
The intent of this credit is to reduce concentrations of chemical contaminates that can damage air quality, human health, productivity and the environment.
This is a significant change from LEED 2009 and it will take some time for these requirements to be developed by the manufacturers. Additionally, these credits are not etched in stone, LEEDv4 will continue to evolve and these credits may be modified prior to the mandatory LEED registration date of October, 2016.
