Reversibility for Lifecycle Decarbonisation in Protected Built Heritage: A Qualitative Framework and Two Case Studies

This dataset supports the qualitative analysis presented in the manuscript “Reversibility for Lifecycle Decarbonisation in Protected Built Heritage: A Qualitative Framework and Two Case Studies” (Building Research & Information, Manuscript ID 261482486). It contains the Reversibility–Lifecycle Carbon Matrix (RLCM) indicator definitions, the 0–3/ND scoring protocol, the E1/E2/E3 evidence hierarchy, and the evidence matrices used for the two protected built-heritage case studies: Palazzo Ducale in Serre and Ave Gratia Plena in Sessa Aurunca, Italy. The dataset reports the documentary basis and qualitative lifecycle interpretation supporting each assessment. It does not contain a quantitative lifecycle carbon inventory and should not be interpreted as reporting measured carbon savings. Underlying project documentation is not redistributed where public dissemination rights have not been established.
