Intent
To quantify the embodied carbon impacts of the structure, enclosure, and hardscape of a project and assess the top sources of embodied carbon.
Requirements
Comply with the following requirements:
Embodied Carbon
- Quantify the embodied carbon impacts - global warming potential or (GWP) - of the structure, enclosure, and hardscape materials for the project. All ancillary structures, such as parking structures or outbuildings within the LEED project boundary, must be included in the calculations. At a minimum, include asphalt, concrete, masonry, structural steel, insulation, aluminum extrusions, structural wood and composites, cladding, and glass.
- Quantify the cradle-to-gate (A1–A3) embodied carbon emissions for each material, defined as the product’s GWP/unit times the amount of material used.
- Alternatively, projects using life-cycle assessment or embodied carbon software tools may report A1–A3 results from their tool.
AND
High-Priority Embodied Carbon Sources
Identify the top three sources of embodied carbon on the project and describe how project-specific strategies were considered to reduce the impacts of these hot spots.
Core and Shell only
Communicate the embodied carbon measurements and material suppliers in the tenant guidelines.
What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
