Abstract:
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.
