Hemp and lime warehouse for wine society

Following in the footsteps of the Adnams brewery building which was constructed of hemp and lime blocks, the UK's first warehouse building made using preformed wall panels made out of hemp has now been completed.
Hemp and lime warehouse for wine society

The £3.7m warehouse for the Wine Society in Stevenage, Hertfordshire, has been designed by architect Vincent & Gorbing and has exterior walls built of Tradical Hemcrete, which is a mixture of hemp stalk and modified lime. It is a development of the previously used cast insitu hemp-lime walling, and blocks, that lock carbon dioxide within the wall construction. The Hemcrete is made using hemp fibre - shiv - grown in the UK, and being a plant material it takes up and locks in CO2 from the atmosphere as it grows. The use of lime to bind it rather than cement also avoids the use of the CO2 heavy and energy intensive cement manufacturing process.

Mark Chandler, architect and director of Vincent & Gorbing, said: “The design responds to the requirement for minimal heating and cooling equipment with the resultant reduction in energy consumption.”

The cladding offers good insulation properties, explains Chandler, and helps maintain a stable internal air temperature throughout the summer and winter. essential for storing wine which needs a constant temperature.

The 8.5m2 panels, which are 300mm thick, are mounted on the building's steel truss frame, while a 40mm-thick composite aluminium panel is used to provide weather protection on the external face. Daylight is allowed in by the use of a translucent, insulating fibreglass material, and together with the highly insulated roofing system, it provides an insulated internal space that exceeds Building Regulations requirements.
