Hemp is emerging as a valid bio-based alternative to concrete, inspired by environmental and energy-saving criteria. Hemp concrete, in fact, is a carbon-negative material: the carbon hemp absorbs as a plant makes up for the carbon emitted during the processing phase of hempcrete. More, it has a positive health impact as it releases no chemicals, and performs well technically, for acoustic and thermal insulation. Many projects are already proving their great potential:

- Regional House Edeghem | BC architects (Brussels, BE)—is an educative and participative experience that explores an ecological and sustainable approach to construction. The hempcrete is used to insulate the facades and the roof and is left untreated to maintain its breathability, making the building CO2-negative.

- Flat House | Practice Architecture + Material Cultures (Cambridgeshire, UK)—is a pre-fabricated hemp-based construction made of a brand new hemp fiber cladding product. The collaboration led to the establishment of Material Cultures, a research organization whose aim is to explore biomaterials in the context of off-site construction.

- Pierre Chevet Sports Center | Lemoal Lemoal (Paris, FR)—is carried by a wooden half-vaulted frame that is adjoined to the hempcrete walls for support. Hemp is also used for insulation.

- Hemp House | Steffen Welsch Architects (Collingwood, AU)—is the first hempcrete house in Australia. Hemp was chosen to optimise heating and cooling thanks to its breathability, while not forgetting quality of aesthetics, acoustics, and air quality, given that it is an effective acoustic insulator, and it creates a cosy and warm atmosphere.

- Mobius House of Hemp Bricks and Concrete | Gibbons Design—is entirely made out of hempcrete blocks reinforced with concrete, which expresses the house’s connection with nature.
