This session will explore the lessons learned from a first of its kind partnership between the ICFMA, NRMCA, and Habitat for Humanity, through which Habitat will construct 15 houses across the United States in 2021. The projects aim to address affordability, sustainability, and resilience of insulated concrete forms (ICFs) and concrete structures as a viable alternative to wood-frame construction. The focus of this session will include case studies from projects constructed where wildfires, tornadoes, hurricanes, and extreme temperatures make homeownership increasingly unattainable from a cost standpoint.
Learning Objectives:
(1) Compare cost houses constructed with ICF walls versus wood frame walls;
(2) Review the sustainability aspects of houses constructed with ICF walls versus wood frame walls;
(3) Discuss the resiliency performance of houses constructed with ICF walls versus wood frame walls;
(4) Review of case studies of ICF and concrete structures in locations with challenging natural environments (hurricanes, tornadoes, wild fires and extreme high temperatures) which impact cost of construction and affordability of housing.


12:00 PM - 1:00 PM

Speaker: Kelly Roberts
Title: Embodied Carbon and the Concrete Industry: What you need to know
Buildings alone account for 40% of the global greenhouse gas emissions. Two thirds of that total impact is from operational emissions while the remainder is from embodied emissions. Embodied emissions include all the emissions required to produce everything that goes into our buildings – the structure, enclosure and all the materials inside. Between now and 2050, half of the new construction emissions between now and then will be from embodied carbon. Therefore, the industry has begun to take action and groups like AIA 2030, Architecture 2030, SE2050, and USGBC have shifted their focus to include embodied carbon. In order to address this issue, we need to take steps to quantify and then reduce our impact. We can do this using a process called Whole Building Lifecycle Assessment (WBLCA). More and more project teams are using WBLCA as a design tool and are discussing decarbonizations strategies. As such, design professionals are actively and looking for low carbon material alternatives. Since cement is such a ubiquitous and carbon-intensive material, it is definitely at the center of these discussions. It’s important that the concrete industry be aware of what is being discussed in the market and how this will affect our industry in the future as this trend grows. This presentation will also look at examples of how this translates to the design documents, the specifications and ultimately the concrete mix designs.

This mini-session is a recurring event focused on the latest developments, case studies, and lessons learned in the area of concrete constructability. Arguably, constructability is one of the most overlooked components of concrete project design and planning. Yet if not properly addressed, it can result in a variety of issues during the construction phase of the project, including negative impacts on the project schedule and budget. Often, the devil lies in the details when it comes to constructible projects. This session will aim at discussing a variety of constructability-related topics that will be based on real-world experiences and case studies.
Learning Objectives:
(1) Recognize recent developments in the area of concrete constructability;
(2) Describe frequent issues occurring on concrete projects that negatively impact constructability, schedules, and project budgets;
(3) Identify potential constructability pain points and acquire proven strategies to prevent them from occurring;
(4) Explain the design behind complicated project elements and alternative methods to construct them.
