USGBC LEEDv4 Offers New Material Health Credits Using GreenScreen®
This year, for the first time, the U.S. Green Building Council incorporates health considerations into its building standards with its new LEED v4 standard. The new standard offers credits for using the GreenScreen for Safer Chemicals.
LEED v4 takes effect in November, 2013. Those seeking LEED certification have two options for credits under Materials & Resources -- for disclosing and optimizing where building materials are sourced and purchased.
For New Construction, read the credit language here.
For Commercial Interiors, read the credit language here.
Here’s how it works:
Option 1. Material Ingredient Reporting (Disclosure)
This LEED credit is for products with chemical ingredients that have been fully inventoried 1000 ppm.
For manufacturers who do not wish to disclose certain chemicals in their products, they can do a full GreenScreen assessment of those chemicals and report according to the LEED credit.
For the Disclosure credit, the goal is to drive greater transparency in reporting and does not preclude the presence of Benchmark 1 chemicals in a product.
Option 2. Material Ingredient Optimization
This LEED credit is for products with chemical ingredients that have been fully inventoried 100 ppm AND that have no Benchmark 1 hazards.
There are two ways to demonstrate the absence of Benchmark 1 hazards. The simplest way is to use the GreenScreen List Translator, for which products are valued at 100% of cost. The second way is to use the full GreenScreen method, for which products are valued at 150% of cost.
For those manufacturers who are able to provide full ingredient transparency, it is straightforward to earn both the Disclosure and the Optimization credits (valued at 100% of cost) by using the HPD and the GreenScreen List Translator.
For those manufacturers who either need assistance tracking down chemical ingredient information from their supply chain or who are unable or unwilling to provide full ingredient transparency, a Licensed GreenScreen Profiler can serve as a valued third party to facilitate earning this credit by performing either GreenScreen List Translator screens or full GreenScreen assessments (valued at 150% of cost).
For the Optimization credit, the goal is to drive the use of building products that contain inherently safer chemicals.
