Model Embodied Carbon Specifications

Beginning in July 2025, BCBF WA requires the collection of EPDs and optional additional data for all “covered product types” used in the construction of new state buildings over 100,000 sq ft (phased down to 50,000 sq ft in 2027).

Covered products include:

Structural concrete products of the following types:

• Ready mix (cast-in-place) concrete
• Spritzbeton
• Precast concrete
• Betonmauerwerk (CMU)

Reinforcing steel products of the following types:

• Bewehrung
• Post-tensioning tendons

Structural steel products of the following types:

• Hot-rolled structural steel
• Hollow structural steel
• Metal deck
• Structural steel plate

Wood products of the following types:

• Glue laminated beams and timbers (Glulam)
• Brettsperrholz (CLT)
• Dowel laminated timber (DLT)
• Nail laminated timber (NLT)
• Laminated veneer lumber
• Parallel strand lumber
• Prefabricated wood joists
• Wood structural panels
• Solid sawn and structural lumber
• Structural composite lumber

BCBF WA does not require setting or meeting low embodied carbon targets, but project design/construction teams can choose to add embodied carbon optimization requirements to the project, so those specification sections are included as optional in red text.

These optional optimization sections include:

• Embodied Carbon Optimization Targets
• Embodied Carbon Baseline by material or product type
• Guidance language for calculating the GWP proposed and % of GWP benchmark

Das Model Embodied Carbon Specifications include the following sections:

Division 1 Section 018113 – Sustainable Design Requirements

• Includes supply chain reporting requirements for products as defined by the Buy Clean and Buy Fair Washington Act.
• This section should always be included in any specification that requires EPDs and/or meeting embodied carbon material limits.

The additional material-specific sections are intended to be inserted into a complementary Construction Specifications Institute (CSI) formatted project specification, with the added sections supplementing other material-specific requirements.

Division 3 Section 033000 – Cast-in-Place Concrete

• Includes a table of Benchmark Global Warming Potential values by Concrete Class for the Pacific Northwest Region as reported in the NRMCA Member National and Regional Life Cycle Assessment Benchmark (Industry Average) Report – Version 3.2, dated December 2023. These regional benchmarks should be updated to reflect the NRMCA region where the project is located.

Division 3 Section 034000 – Precast Concrete und Section 033713 – Shotcrete

Division 4 Section 042000 – Unit Masonry

Division 5 Section 051000 – Structural Steel

Division 6 Section 061XXX –

• For ease of sharing this template specification language, all of the wood “covered product types” listed in the BCBF WA Act have been shown in one template specification section.  There are many potential Division 06 Specification Section names and numbers that may include one or more of the wood-covered product types, including:
• 061543 – Cross Laminated Timber (and Mass Plywood)
• 061715 – Engineered Structural Wood (LVL, PSL, LSL, etc.)
• 061800 – Glued-Laminated Construction
• 061516 – Wood Roof Decking
• 061760 – Prefabricated Wood Trusses

Sustainable Product Data Reporting Form

• This form was developed with the intention to be submitted with product data submittals for all BCBF WA “covered product types” to be installed in the project, and can be modified for your project.
