This section specifies requirements related to the environmental and human health impacts of materials, including resource conservation, reduced life-cycle impacts of building materials, impacts on the atmosphere, product transparency, and waste management.
The building materials shall comply with Section 901.3 (9.3), “Mandatory Provisions,” and either
A minimum of 50% of nonhazardous construction and demolition waste material generated prior to the issuance of the final certificate of occupancy shall be diverted from disposal in landfills and incinerators by reuse, recycling, repurposing, and/or composting. Excavated soil and land-clearing debris shall not be included in the waste diversion calculation. Alternative daily cover and waste-toenergy incineration shall not be included as diverted material. All diversion calculations shall be based on either weight or volume, but not both, throughout the construction process.
Informative Note: Reuse includes donation of materials to charitable organizations; salvage of existing materials onsite; reclamation of products by manufacturers; and return of packaging materials to the manufacturer, shipper, or other source for reuse as packaging in future shipments.
For new building projects on sites with less than 5% existing buildings, structures, or hardscape, the total amount of construction waste generated prior to the issuance of the final certificate of occupancy on the project shall not exceed 42 yd3 or 12,000 lbs per 10,000 ft2 (35 m3 or 6000 kg per 1000 m2) of new building floor area. This shall apply to all waste, whether diverted, landfilled, incinerated, or otherwise disposed of. Excavated soil and landclearing debris shall not be included in the calculation. The amount of waste shall be tracked throughout the construction process in accordance with the construction waste management plan required in Section 901.3.1.3 (188.8.131.52).
Prior to issuance of a demolition or building permit, a preconstruction waste management plan shall be submitted to the owner. The plan shall:
a.identify the construction and demolition waste materials expected to be diverted,
b.determine whether construction and demolition waste materials are to be source-separated or comingled,
c.identify service providers and designate destination facilities for construction and demolition waste materials generated at the job site, and
d.identify the average diversion rate for facilities that accept or process comingled construction and demolition materials. Separate average percentages shall be included for those materials collected by construction and demolition materials processing facilities that end up as alternative daily cover and incineration.
This section applies to all materials, products, and/or assemblies installed prior to the issuance of the final certificate of occupancy.
Materials shall be harvested and/or extracted, and products and/or assemblies shall be manufactured, according to the laws and regulations of the country of origin.

b.Electric lamps with a rated lifetime equal to or greater than 25,000 hours when tested on an electronic fluorescent ballast, including T8 instant-start ballasts and T5 programmed-start ballasts, and turned OFF and ON every three hours.
The building project shall comply with any two of the following: Sections 901.4.1.1, 901.4.1.2. 901.4.1.3, or 901.4.1.4 (184.108.40.206, 220.127.116.11, 18.104.22.168, or 22.214.171.124). Calculations shall only include materials permanently installed in the project. A value of 45% of the total construction cost shall be permitted to be used in lieu of the actual total cost of materials.
The sum of the recycled content and the salvaged material content shall constitute a minimum of 10%, based on cost, of the total materials in the building project.
The recycled content of a material shall be the postconsumer recycled content plus one-half of the preconsumer recycled content, determined by weight (mass). The recycled fraction of the material in a product or an assembly shall then be multiplied by the cost of the product or assembly to determine its contribution to the 10% requirement.
The annual average industry values, by country of production, for the recycled content of steel products manufactured in basic oxygen furnaces and electric arc furnaces shall be permitted to be used as the recycled content of the steel. For the purpose of calculating the recycled content contribution of concrete, the constituent materials in concrete (Informative Note: e.g., the cementitious materials, aggregates, and water) shall be permitted to be treated as separate components and calculated separately.
The salvaged material content shall be determined based on the actual cost of the salvaged material or the cost of a comparable alternative component material.
A minimum of 15% of building materials or products used, based on cost, shall be regionally extracted/harvested/recovered or manufactured within a radius of 500 mi (800 km) of the project site. If only a fraction of a product or material is extracted/harvested/recovered or manufactured locally, then only that percentage (by weight) shall contribute to the regional value.
Exception: For building materials or products shipped in part by rail or water, the total distance to the project shall be determined by weighted average, whereby that portion of the distance shipped by rail or water shall be multiplied by 0.25 and added to that portion not shipped by rail or water, provided that the total does not exceed 500 mi (800 km).
A minimum of 5% of building materials used, based on cost, shall be biobased products. Biobased products shall:
a.comply with the minimum biobased contents of the USDA’s BioPreferred Program;
b.contain the “USDA Certified Biobased Product” label; or
c.be composed of solid wood, engineered wood, bamboo, wool, cotton, cork, agricultural fibers, or other biobased materials with at least 50% biobased content.
Wood building components, including but not limited to structural framing, sheathing, flooring, subflooring, wood window sash and frames, doors, and architectural millwork, used to comply with this requirement shall contain not less than 60% certified wood content tracked through a chain of custody process, either by physical separation or percentagebased approaches, or wood that qualifies as a salvaged material. Certified wood content documentation shall be provided by sources certified through a forest certification system with principles, criteria, and standards developed using ISO/IEC Guide 59 or the WTO Technical Barriers to Trade. Wood building components from a vendor shall be permitted to comply when the annual average amount of certified wood products purchased by the vendor, for which they have chain of custody verification not older than two years, is 60% or greater of their total annual wood products purchased.
A minimum of ten different products installed in the building project at the time of issuance of certificate of occupancy shall comply with one of the following subsections. Declarations, reports, and assessments shall be submitted to the authority having jurisdiction (AHJ) and shall contain documentation of the critical peer review by an independent third party, results from the review, the reviewer’s name, company name, contact information, and date of the review or certification.
A Type III industry-wide environmental product declaration (EPD) shall be submitted for each product. Where the program operator explicitly recognizes the EPD as fully representative of the product group on a national level, it is considered industrywide. In the case where an industry-wide EPD represents only a subset of an industry group, as opposed to being industry-wide, the manufacturer shall be explicitly recognized as a participant by the EPD program operator. All EPD shall be consistent with ISO Standards 14025 and 21930, with at least a cradle-to-gate scope. Each product complying with this section shall be counted as one product for compliance with Section 901.4.1.4 (126.96.36.199).
A product-specific Type III EPD shall be submitted for each product. The product-specific declaration shall be manufacturer-specific for a product family. Type III EPDs shall be certified as complying with the goal and scope for the cradle-to-gate requirements in accordance with ISO Standards 14025 and 21930. Each product complying with this section shall be counted as two products for compliance with Section 901.4.1.4 (188.8.131.52).
A material-specific assessment shall be submitted for each product in accordance with one of the following standards, where applicable. The assessment shall be certified as meeting the minimum performance level specified in each standard. Each product complying with this section shall be counted as two products for compliance with Section 901.4.1.4 (184.108.40.206).
A report by a third-party that has critically reviewed the lifecycle assessment (LCA) of a product, based on ISO Standards 14040 and 14044, shall be submitted. The report shall demonstrate compliance with the goal and scope for the cradle-to-gate requirements. Each product complying with this section shall be counted as two products for compliance with Section 901.4.1.4 (220.127.116.11).
An LCA shall be performed in accordance with ASTM E2921 and ISO Standard 14044, as modified by this section, for a minimum of two building alternatives, both of which shall conform to the owner’s project requirements (OPR).
The LCA shall demonstrate that the final building design achieves one of the following minimum improvements over the reference building design assessed in the LCA:
a.Ten percent (10%) improvement in a minimum of each of two impact categories, one of which must be global warming.
b.Five percent (5%) improvement in a minimum of each of three impact categories, one of which must be global warming.
The following impact categories shall be used to determine compliance with this section and shall be included in the report described in Section 901.5.1.3 (18.104.22.168): land use, resource use, global warming, ozone layer depletion, human health effects, ecotoxicity, smog, acidification, and eutrophication.
The LCA shall be performed in accordance with the service lives, life-cycle stages, study boundaries, and comparison methodologies of ASTM E2921 with the following modifications:
b.The service life of the buildings shall not be less than that determined using Table 1001.3.2.3 (10.3.2.3), except that the service life of long-life buildings shall be no less than 75 years.
c.Operating energy consumption shall be included or excluded at the discretion of the project team.
d.The LCA tool (or tools) or software shall include a published third-party impact indicator method.
e.The estimate of structural system material quantities shall be verified by a design professional or other approved source.
A report that includes a description of the building alternatives and their physical differences shall be prepared and shall comply with the reporting requirements stated in ASTM E2921. The name and address of the design professional or other approved source verifying structural system material quantities shall be included. A critical review shall be performed by an external expert independent of those performing the LCA.
The report shall be submitted to the AHJ and include documentation of critical peer review by a third party, results from the review, and the reviewer’s name and contact information.
