La decarbonizzazione del Patrimonio edilizio richiede interventi di retrofit scalabili capaci di ridurre non solo i consumi operativi ma anche il carbonio incorporato lungo il ciclo di vita. Il contributo propone un quadro di supporto alle decisioni replicabile, che considera prefabbricazione leggera, scenari di fine vita e metriche temporali mediante la Dynamic Life Cycle Assessment (DLCA). Il metodo è applicato al Nature-based Retrofit System (NoRS), sistema di retrofit di facciata a base biologica assemblato a secco con pannelli in paglia di riso lavorabili a controllo numerico (CNC), e confrontato con un sistema in legno di pari prestazioni. I risultati mostrano che l’analisi temporale DLCA rende visibili compromessi che la LCA statica non intercetta: i benefici variano in funzione della rigenerazione della biomassa e degli scenari di fine vita, con una marcata sensibilità alle emissioni differite di metano in discarica.
