Embodied Energy of drywall
As a contractor, in an effort to reduce the embodied energy in the projects I work on, I have always encouraged my clients to avoid foam insulation where possible and minimize the use of concrete where practical.
Recently I have been involved in a design process with an architect who has argued that the embodied energy in gypsum board drywall is enough to overshadow the differences between different types of insulation(for example, foam vs. cellulose).
Since my clients would like to have drywall on their walls, but also minimize the carbon footprint of their project, I would like to be able to verify or refute this argument. It has also made me wonder if the carbon footprint of drywall gets relatively little attention from the green building community because the alternatives are largely incompatible with conventional building techniques.
I have not found a resource which puts this information into a meaningful context for me, but I am eager to hear opinions on the matter and happy to be pointed towards information which will help me put the embodied carbon of drywall into the larger context of the entire project.
