Sometimes the things we think are a poor environmental choice turn out to be not so bad. Sometimes they are worse. Ben Morelli, along with Bensonwood energy & sustainability experts – Rheannon DeMond and Danny Veerkamp - will discuss the results of an LCA of a single family home; from material source through building lifespan. Life cycle assessment (LCA) is one of many emerging tools available to building designers and construction firms to measure and guide reduction of their structures’ environmental impact. The presenters feel it is essential to look at a broad variety of impact categories –not just climate and energy considerations - in order to assess the trade-offs that may be associated with the emerging paradigm of advanced, green buildings. The results of this analysis confirm the importance of systemic energy reduction strategies, while challenging some of our preconceived assumptions on the relative impacts of various materials.
