Proposed Session Description
Some of the most efficient building envelope design strategies for reducing operational carbon involve increasing the enclosure assemblies’ thermal performance and requiring highly airtight systems. However, we are only starting to understand the trade-offs between operational and embodied decarbonization. To evaluate the trade-off, this session will directly compare wall assemblies in a high-performance new construction building and wall assemblies in common existing building typologies.
Why is this session important?
Legislation and decarbonization efforts in the design and construction community focus primarily on operational carbon. However, there is a growing awareness that the relationship or ratio of embodied carbon versus operational carbon must also factor in to decarbonization efforts in the built environment. This session examines the impacts of prioritizing embodied versus operational carbon in three specific high-performance wall assemblies and three historic wall assemblies. While the data is by no means comprehensive or broadly applicable, it offers a starting point for discussions about how to balance the ratio of embodied carbon vs operational carbon when reviewing preservation concerns.
Diversity and Inclusiveness
Decarbonization provides benefits for everyone, but especially the most marginalized people due to the concentration of factories and disposal sites in communities with lower incomes and less political influence. The study of embodied carbon makes a strong case for reuse, rather than demolition and reconstruction, which also benefits people through cleaner air, and fewer airborne particles from demolition and manufacturing. It also emphasizes the case for preserving the diverse buildings and spaces that are important to maintaining community connections and history.
Learning Objectives
Understand how embodied carbon is calculated.
Identify resources for determining embodied carbon.
Identify the construction methods and materials that can lower embodied carbon impacts.
Identify known strategies for reducing operational carbon in both new high-performance construction and historic building retrofits.
Has this session been presented before?
No
Additional Comments
A portion of the presentation was presented at PHIUS 2022 Conference. At that conference, the presentation focused on embodied carbon analysis of PHIUS wall assemblies. This proposal expands the topic to include embodied carbon analysis of retrofitted historic wall assemblies and discusses known decarbonization strategies.
