IMPLEMENT A SMART CARBON CONSTRUCTION PROCESS
When integrating design intent with local building code criteria, how can the lowest embodied carbon
construction system be integrated into the project goals?
Is there a path to a more efficient construction process to reduce materials and streamline assembly?
How can the design be achieved by using more building construction systems as final finishes?
1. Establish Goals With Key Stakeholders
Facilitate a process to discuss opportunities to reduce embodied and operational carbon for projects.
• Conduct a visioning charrette to align key business drivers with project goals.
• Investigate the construction process and assembly for areas to reduce carbon.
2. Low Embodied Carbon Construction System
When determining the construction systems, consider the embodied carbon associated with each
component.
• For concrete assemblies, avoid or modify the mix design to minimize the use of portland cement.
Instead, opt for alternative low-carbon binders that still meet the required strength specifications
(i.e. fly ash, silica fume, slag, calcined clays, bio-based materials, or alkali-activated binders).
Additional considerations should be given to higher PSI concrete to reduce overall volume of
material.
• For steel assemblies, consider right-sizing members with smaller section/overall weight and
prioritize salvaged steel where that design can accommodate.
• For wood assemblies (biogenic), carbon sequestration can be factored to offset other materials
used and should be considered as the preferred basis of design for alignment with low carbon
goals.
3. Prefabricated assemblies
Prefabricated assemblies offer a strategic advantage by assembling components in a factory or
manufacturing site before transporting them to the construction site. This approach optimizes various
aspects of the construction assembly process. This also increases quality control and assembly
tolerances while minimizing construction time frame and material waste.
• Mass Timber (i.e. glulam, CLT, etc.) (Reference Appendix p125 for more detailed information)
• Concrete (double tees, floor cassettes)
• Unitized Wall Assemblies
• Modular construction assemblies (i.e. pods)
4. Construction Waste Management Plan
Create a written document that outlines how to manage construction waste during a project. The
plan aims to reduce the environmental impact of waste while also helping contractors save money
by managing it more efficiently. A final report will detail all waste generated, including disposal and
diversion for the project.
• Identify strategies to reduce waste generation during design and construction.
• Establish waste diversion goals (i.e. 50% good, 75% great, above 90% excellent).
