Oggi, alla luce delle impellenti e improrogabili azioni di intervento, volte a contrastare le emergenze ambientali e climatiche, la canapa industriale è tornata al centro del dibattito scientifico come risorsa strategica per la transizione ecologica. Grazie alla riscoperta di saperi costruttivi tradizionali, ai risultati straordinari raggiunti dalla ricerca in merito alle sue potenzialità e ai nuovi possibili campi di applicazione, questo materiale si propone oggi come elemento chiave per modelli sostenibili di sviluppo ambientale, economico e sociale. In particolare, il settore edilizio, tra i più impattanti dal punto di vista ambientale, rappresenta un ambito prioritario per l’adozione di materiali e tecnologie capaci di ridurre consumi energetici, emissioni climalteranti e uso di risorse non rinnovabili. Il contributo analizza le caratteristiche agronomiche e ambientali della canapa, le proprietà fisiche e termo-igrometriche dei materiali edilizi derivati e le principali tecnologie costruttive, con particolare attenzione al calcestruzzo di canapa. Le potenzialità della canapa in architettura vengono delineate attraverso un’analisi critica della letteratura scientifica e una lettura comparata di casi studio e sperimentazioni applicative, individuando criticità normative e prospettive di sviluppo future nel campo della bioedilizia.

Abstract

Today, considering the urgent and unavoidable need for action to address environmental and climate emergencies, industrial hemp has returned to the forefront of scientific debate as a strategic resource for the ecological transition. Thanks to the rediscovery of traditional construction knowledge, the remarkable advances achieved by research into its potential, and the emergence of new fields of application, hemp is now recognized as a key material for fostering sustainable models of environmental, economic, and social development. In particular, the construction sector, one of the most environmentally impactful industries, represents a priority area for the adoption of materials and technologies capable of reducing energy consumption, greenhouse gas emissions, and the use of non-renewable resources. This paper examines the agronomic and environmental characteristics of industrial hemp, the physical and hygrothermal properties of hemp-based building materials, and the main construction technologies, with particular emphasis on hempcrete. The potential of hemp in architecture is explored through a critical review of scientific literature and a comparative analysis of case studies and applied research, identifying current regulatory challenges and future development prospects in the field of sustainable bio-based construction.
