Innovative, sustainable construction products are emerging in response to market demands. One potential product, insulating concrete forms (ICFs), offers possible advantages in energy and environmental performance when compared with traditional construction materials. Even though ICFs are in part derived from a petroleum-based product, the benefits in the use phase outweigh the impacts of the raw material extraction and manufacturing phase. This paper quantitatively measures ICFs' performance through a comparative life cycle assessment of wall sections comprised of ICF and traditional wood-frame. The life cycle stages included raw materials extraction and manufacturing, construction, use and end of life for a 2,450 square foot house in Pittsburgh, Pennsylvania. Results showed that even though building products such as ICFs are energy intensive to produce and thus have higher environmental impacts in the raw materials extraction and manufacturing phase, the use phase dominated in the life cycle.
