Massachusetts 100‐Home Embodied Carbon Study
The Massachusetts 100-Home Embodied Carbon Study provides a comprehensive assessment of embodied carbon emissions across a representative sample of residential buildings. By analysing material quantities, construction systems, and design variables, the study identifies the primary sources of emissions and evaluates the potential for reduction using currently available strategies.
Results indicate that structural elements, particularly concrete foundations and framing systems, are the dominant contributors to embodied carbon. Envelope components, including insulation and exterior assemblies, also play a significant role. Importantly, the study demonstrates that reductions in the range of 20–30% are achievable through material optimisation, the specification of lower-carbon alternatives, and improved design efficiency.
A key finding is the disproportionate impact of early-stage design decisions, which largely determine the carbon footprint of a project before construction begins. The report emphasises the necessity of integrating embodied carbon considerations into standard design workflows and highlights the value of benchmarking and data-driven decision-making.
Overall, the study provides actionable insights for architects, engineers, and developers seeking to reduce emissions and align residential construction with decarbonisation targets.
