How structural engineers can help

In this episode, Holmes Associate Principals Megan Stringer, SE, LEED, AP, BD + C will talk about embodied carbon reductions and how engineers can help embody carbon reductions during construction. increase.

Here are some of the questions we ask Megan:

  • What is embodied carbon and why is it important?
  • How can structural engineers reduce the embodied carbon during construction?
  • What is the Structural Engineer 2050 Commitment Program? And how do you aim to support concrete carbon reductions?
  • What is the most creative thing you’ve seen in the Embodied Carbon Action Plan (ECAP) regarding how engineering companies have reduced embodied carbon?
  • What is a life cycle assessment?
  • What was your involvement North America’s Largest Mass Timber Building — Cross Laminated Timber (CLT) Structure??
  • What kind of career advice would you give to a young engineer who wants to be as successful as you?

Here are some of the important points discussed here Materialized carbon reductions during construction:

  • The environmental impact of a building is called the initial impact or the embodied impact. The embodied carbon is the sum of the equivalent greenhouse gas emissions emitted during the building’s life cycle. This includes material extraction, raw material manufacturing for structural materials, transportation impacts, construction impacts, maintenance impacts, and end-of-life impacts. Structural engineers need to find out how many materials they need and how to use low-emission materials.
  • Structural engineers can reduce the materialized carbon during construction by specifying more materialized carbon-rich concrete mixtures and fewer materialized carbon-rich materials. This can be done by reviewing the Environmental Product Declaration for Low Carbon Materials.
  • The Carbon Leadership Forum has launched a challenge to structural engineering experts to reduce the carbon embodied in all projects by 2050. This created the Structural Engineer 2050 Commitment Program. There are many structural engineering companies participating in the program to reduce the embodied carbon in the project and submit the project to the carbon embodied database. Participation in the program requires a letter from the company leadership to commit to the program’s requirements and a concrete carbon action plan. You also need to submit a certain amount of embodied carbon data to the central database.
  • The Embodied Carbon Action Plan (ECAP) promises that companies will reduce the carbon embodied in their projects. Many companies already have a way to track the carbon embodied in their projects. Many companies have groups that discuss different topics each month. There is also a compilation of various case studies of the project. It’s interesting to see the many ways companies are trying to reduce the embodied carbon and the results they are getting.
  • Life cycle assessment is basically environmental accounting for all inputs and outputs that enter the building. Investigate all the environmental impacts of a building, from the availability of raw materials to the useful life of the building.
  • North America’s largest high-volume wooden building is unique because it has a composite floor with concrete. It relies on both materials to achieve expansion and contraction and to handle loads. The building has a large rooftop greening, which greatly contributes to the load. Large numbers of wooden buildings have one-third less carbon materialized than concrete buildings. It can be difficult to procure the amount of timber needed to build this type of project. Large amounts of lumber make a significant contribution to reducing the carbon content of our structures.
  • To be successful as an engineer, you need to find and participate in your passion. Participating in committees and professional organizations helps to connect with many people in leadership roles and open up opportunities of all kinds.
