EBOM-v4 MRc3: Purchasing - facility maintenance and renovation

Add the following section under "Product Manufacturer Supply Chain Optimization" section:

Calculation Product Manufacturer Supply Chain Optimization
Use the following equation for Option 3 Supply Chain Optimization (see Further Explanation, Supply Chain Optimization). Products that meet the requirements of Option 3, as outlined below, contribute toward earning LEED credit at 100% of the product cost. To encourage actions beyond those minimum requirements, additional credit can be earned in a number of ways.
Equation 2 Percentage Supply Chain Optimization of compliant materials cost.
% of materials cost = {〖product cost〗_1 (criterion val.factor)(supply chain depth factor)(location val.factor)} + {〖product cost〗_2 (criterion val.factor)(supply chain depth factor)(location val.factor)} + ⋯ X100 / Cost of all permanently installed products
where:
Criteria valuation factor = multiplier assigned to number of enhanced achievement measures
100% value (by cost) where the minimum requirements are met.
150% value (by cost) where the minimum requirements plus:
Inventory and screening performed to 99.9% level
OR
Use GHS Category 2 criteria for hazard screening for carcinogens, mutagens, reproductive toxicants, and skin irritants for determining which ingredients are subject to management, reporting, and optimization (the basic requirement stops at GHS Category 1 for these endpoints). See Table 1.
OR
The building product manufacturer shall require either self-declared or third-party validated environmental management and health & safety management systems as described in the requirements in Section 4 for ALL ingredients up to the 99% threshold, not just those that fail the initial hazard screen. If the building product manufacturer is also seeking extra credit in the Supply Chain Depth factor, this would also apply to all ingredients at the additional tier or tiers.
The building product manufacturer shall document substitution or elimination of at least one ingredient that was flagged in the hazard screening process. Where substitution occurs, manufacturer shall take action based on that alternatives assessment such that the hazard is no longer flagged at the Enhanced Achievement hazard Criteria level (table 1) in place of the original ingredient.
200% value (by cost) where the minimum requirements are met plus any two of the four above options.

Supply chain depth factor = multiplier assigned to level of supply chain engagement
100% value (by cost) where the minimum requirements are met.
150% value (by cost) where the minimum requirements plus one of these two:
The building product manufacturer has met the Option 3 minimum requirements for the entire business unit or company.
OR
All tier 2 suppliers have documented processes in place as described for tier 1 suppliers. This multiplier is not available to products with only tier 1 suppliers in their supply chain.
200% value (by cost) where the minimum requirements plus:
All suppliers in the supply chain of the product have documented processes in place as described for tier 1 suppliers. This multiplier is not available to products with only tier 1 and tier 2 suppliers in their supply chain.

Add the following definitions, in alphabetical order:
Building product manufacturer: Any company making an product for incorporation into the project that would arrive at the job site.
Business unit: A logical segment of a company that represents a specific operational function or production of a product type. Also called department, division, or a functional area.
Component: Uniquely identifiable input, part, element, piece, assembly or subassembly, system or subsystem, that (1) is required to complete or finish an activity, item, or job, (2) performs a distinctive and necessary function in the operation of a system, or (3) is intended to be included as a part of a finished, packaged, and labeled product. Components are usually removable in one piece and are considered indivisible for a particular purpose or use. Commonly, items of very small or insignificant cost are not considered components.
Facility: one or more buildings or locations, or part of a building, that it is clearly delineated in the EMS and includes all process associated with the relevant building product (in the case of a Building Product Manufacturer) or ingredient or component (in the case of a supplier to the building product manufacturer).
First-tier supplier: Any company providing components or ingredients directly to a building product manufacturer.
Green chemistry: The design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances (Anastas, P. T. and Warner, J. C. Green Chemistry: Theory and Practice. Oxford University Press: New York, 1998, p. 30).
Green engineering: The development and commercialization of industrial processes that are economically feasible and reduce the risk to human health and the environment (Anastas, P.T., and Zimmerman, J.B., "Design through the Twelve Principles of Green Engineering", Env. Sci. Tech. 2003, 37(5), 94A-101A).
Ingredient: A substance or single constituent of fixed composition, characterized by its molecular structure(s) used to make a compound, mixture, or finished product. Ingredients can be active (help directly in achieving a performance objective(s)) or inert (facilitate acceptance, application, stability, handling or marketing of the product, or delivery of the active ingredients). Ingredients typically have an associate CAS RN (and may also have synonym CAS RNs).
Optimization: Developing a product or process with the highest achievable combination of functional performance, cost, and positive social, environmental, and health impacts by maximizing desired factors and minimizing undesired ones. For the purposes of LEED’s Material Ingredients credit “optimization” implies giving human and environmental health higher priority among the multiple factors than is typically the case.
Second-tier supplier: A supplier providing ingredients to another supplier that end up in the product being considered by the building product manufacturer.

Table 2. GHS Hazard Criteria by Endpoint for Option 3 Screening

Endpoint

If a substance falls into this category, it fails the minimum requirements hazard criteria and is “flagged”/does not pass

If a substances falls into this category, it fails the Enhanced Achievement Option Hazard Criteria (see Section 3 and Note 3)

Carcinogenicity (C)

Category 1 (1A, 1B)

Category 2

Mutagenicity & Genotoxicity (M)

Category 1 (1A, 1B)

Category 2

Reproductive Toxicity (R)

Category 1 (1A, 1B)

Category 2

Acute Mammalian Toxicity (AT) (oral, dermal, and inhalation routes)

Category 1,2,3

-

Systemic Toxicity & Organ Effects (ST‐single exposure)

Category 1

-

Skin Irritation (IrS)

Category 1 (1A, 1B, 1C)

Category 2

Eye Irritation (IrE)

Category 1 or 2A

-

Aspiration Hazard

Category 1

-

-

Acute hazards to the aquatic environment (note 1)

Category 1 or 2 (note 1a)

-

Note 1: For the purposes of this option, USGBC has mapped the GHS Hazard Categorizations to low, moderate, high, and very high. Persistence and bioaccumulation characteristics are factored into the aquatic environment hazards endpoints. As an alternative, if GHS categorizations for the aquatic endpoints are not available and specific empirical science is also not available, then the online PBT Profiler (http://www.pbtprofiler.net/) can be used to determine if the substance falls within the associated GHS categories:

Note 1a: If the fish chronic value (ChV) in the PBT Profiler (or more appropriate metric, as approved by the auditor) is less than 10 mg/L the substance is screened as having a Category 1 or 2 Acute Hazard GHS classification.

Note 1b: If the fish chronic value (ChV) in the PBT Profiler is less than 0.1 mg/L the substance is screened as having a Category 1 or 2 Chronic Hazard GHS classification.

Note 2: In general, this table establishes GHS Category criteria for each endpoint so that chemicals with only "low" or "moderate" hazard classifications for each endpoint pass the rapid hazard screening criteria. The exception is skin irritation, where chemicals characterized as GHS Category 2 (defined as “skin irritation, reversible adverse effects in dermal tissue”) will pass through the screen at the base level of achievement.

Note 3: For Enhanced Achievement in the Rapid Hazard Screen, in addition to the Base Level of Achievement, the inclusion of GHS Category 2 for the Carcinogenicity, Mutagenicity, and Reproductive Toxicity (“CMR”), and Systemic Toxicity & Organ Effects Repeated Exposure sub‐endpoint (ST‐repeat) endpoints allows only chemicals with a “low" hazard condition to pass through the screen. Under GHS language, GHS Category 2 chemicals in one or more CMR endpoints show evidence of having the specific hazard characteristic to be “suspected” of being carcinogenic, etc. This is in contrast to chemicals that are GHS Category 1A or 1B for one or more of the CMR endpoints, which indicate higher hazard evidence that the chemical is a “known” or “presumed" carcinogen, etc.

Similarly, the Enhanced Achievement Criteria adds GHS Category 2 for Skin Irritation as a trigger for further action in addition to CMR endpoints. To receive Enhanced Achievement Credit via the Rapid Hazard Screen, only chemicals showing evidence of moderate or low hazard for Skin Irritation (GHS Category 3) will pass the Enhanced Achievement Rapid Hazard Screening Criteria.
