Jeremy Knoll attends USGBC virtual IMPACT Summit
Jeremy Knoll recently presented at the USGBC virtual IMPACT Summit: Materials, Carbon, and the Circular Environment. Alongside industry peers, Trevor Acorn (Walter P Moore), Erika Winters-Downey (McCownGordon), and Christie Gamble (CarbonCure), Jeremy presented on the topic, “The Elephant in the Room - How to Tackle Embodied Carbon in Practice,” The presentation highlighted the carbon impacts of concrete and steel on the built environment, and a number of methods on reducing embodied carbon emissions associated with both.
Jeremy shared key highlights from the conference:
- Composite design reduces the required volume of steel by allowing concrete and steel to work together.
- Cambering beams, though costly, can reduce the required beam-weight and balance costs with material savings.
- Check deflection tolerances, as these can be "right sized" for your project.
- Develop performance (rather than prescriptive) concrete specifications.
- Use minimum cement reduction/replacement values rather than maximums.
- Refine the required cure times based on the specific application in the building.
- Conduct additional geotechnical testing, such as an on-site test-pile to right-size your structural foundations for the specific measured conditions on site.
- Incorporate C02 into the concrete mix. There are several new technologies which improve strength and cure time while driving the cement content down.”
