A consortium led by BRE (building research establishment) Centre for innovative construction materials, based in the University, built, a small building on the campus of Claverton hemp and Lima, whose properties as test material.
Called the "HemPod", this building, a plant walls made of minced meat / Woody kernel or Shiv, highly insulating industrial hemp plant based in Lima is mixed with a specially designed binder.
Shiv hemp air trapped in the walls and hemp itself is porous, walls, the incredible aisladas.El well Binder CAL together based on sticks and protects the hemp and makes building materials very resistant.
Industrial hemp that takes carbon dioxide, as it grows and lime processing plant even more warming absorbed that effectively the building is a extremely low carbon footprint gas.
Dr. Mike Lawrence, official University Department of Economics of architecture & high and civil engineering, said: "that some houses in the United Kingdom built with hemp and lime is the HemPod are the first building of hemp, Lima was built purely for scientific evidence."
"We will closely follow of the House 18 months with the temperature and humidity sensors that buried in the walls, measure the speed of heat and steam travel by you."
"The walls are breathable and act as a kind of passive air conditioning, which means that the internal humidity remains constant, and the quality of air in the House very buena.Los walls also have a" virtual thermal mass "is because of the porous structure remarkably of hemp Shiv properties of lime, logbook that combines building much more thermally efficient and is the temperature in the House remains fairly constant."
Professor Pete Walker, Director of the BRE for innovative materials, added: "The aim of the project is some solid data, the construction industry to use to convince this building material far."
"Hemp grows very quickly to grow enough hemp only the size of a rugby pitch area to build a typical 3-bedroom house in three months."
"Harvest using renewable, to build houses can provide economic benefits to rural areas, farmers can grow hemp new market openings Agrícolas.Los in summer, how large food cultures, not much water need a crop of rest between its and organically grown.
"Every part of the plant can be used, there is no waste - the Shiv, is used for the development of the fibres can car, clothing or paper panels and seeds for food or a very efficient and renewable material can be used aceite.Por."
Lime has been used for thousands of years in construction and an important development in efforts to more sustainable construction is combined with industrial hemp.
Environmentally friendly building materials are often more expensive than the Department of energy and climate change (DECC) and the national non-food crops (NNFCC) project showed financed traditional materials but renewable House (www.renewable-house.co.uk), a cost of around £ 75,000 (without foundations) to make a House with three bedrooms 4 competitive with conventional brick and mortar to build it code of hemp and Lima.
The project is sponsored by Department for environment, Food & Rural Affairs (Defra) in renewable materials LINK program and brings together a team of nine partners includes: University of bath, BRE Ltd, Feilden Clegg Bradley Studios, Hanson UK, hemp, Lhoist technology group, technology of Lima, the NNFCC and Wates Habitat.
