In early 2023, the NIBS BIM Council established a Digital Twin Integration Subcommittee (DTI-S) to develop a position on the relationship between BIM and digital twins. The chairs from the DTI-S will present the position paper being developed as a reference for the industry.

Precast concrete is a durable, resilient material that can provide many benefits to efficient, sustainable structures in the long term. While concrete does have an upfront CO2 impact, the precast concrete industry is working to reduce GHG greenhouse gas emissions and increase the efficiency of its products. This presentation will discuss technical innovations to reduce the carbon footprint of concrete and examine current process improvements that are pushing the industry forward to a more sustainable future.

The design, construction and operation of buildings account for roughly 40 percent of global energy-related greenhouse gas (GHG) emissions. Energy codes have been an effective strategy in reducing operational energy, but additional activities to address how design strategies and material choices influence the GHG emission impacts of buildings are needed. Reducing those emissions to meet community and industry climate goals will require a comprehensive approach that addresses all stages of the building lifecycle.
