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.For the use phase,the home constructed of ICFs consumed 20 percent less energy when compared to a traditional wood-frame structure.The results of the impact assessment show that ICFs have higher impacts over wood homes in most impact categories.The high impacts arise from the raw materials extraction and manufacturing phase of ICFs.But there are a number of embedded unit processes such as disposal of solid waste and transport of natural gas that contribute to this high impact and identifying the top unit process and substance contributors to the impact category is not intuitive.Selecting different unit processes or impact assessment methods will yield dissimilar results and the tradeoffs associated with every building product should be considered after studying the entire life cycle in detail. 展开更多
