2.  Hemp Lime Bio-composite as a Building Material in Irish Construction (2012) Patrick Daly, Paolo Ronchetti and Tom Woolley

The STRIVE report prepared for Ireland’s Environment Protection Agency presents the finding of a scoping study carried out under the EPA ‘STRIVE’ research funding pro- gramme during 2010 to examine the potential application of hemp lime as a building material in Ireland. The study collated a growing body of international research on hemp lime and reviewed its increasing application in construction, including some significant demonstration projects, (mainly in the UK and France), and also involved industry consultation, a questionnaire, workshops and site visits to production facilities and construction / demonstration projects.

 3. Hygrothermal modelling of Lime-Hemp concrete used as building material and indoor climate buffering characterisation, Dubois, S., Evrard, A., Lebeau, F  

This study showed that LHC can be classified as having an excellent moisture buffer performance and confirms the general idea of agro-sourced material being good indoor climate regulators.

4.  Transient hygrothermal behaviour of hemp lime materials Evrard, A PhD, Université Catholique De Louvain, 2008  

“High inertia of LHM wall components allows them to dampen the effects of daily variation of outside climate, and to delay the effects of peak values or sudden variations. They also regulate inside level of temperature and humidity (TBV and MBV).” “Following sustainable development principles, energy and materials should be considered “from cradle to grave” to improve global performances of buildings. Lime-Hemp Materials (LHM) have numerous advantages: they have low embodied energy, they store CO2, they can be recycled, they adapt to new or old buildings, they give healthy environments…”

5. The British Research Establishment (BRE) and the Suffolk Housing Project  http://projects.bre.co.uk/hemphomes/

This is the earliest project in the UK on which comparative thermographic data houses was collected. The houses were built for Suffolk Housing Society as part of a social housing development. The scheme involved the construction of eighteen dwellings 16 of which were built using conventional masonry construction methods and materials but two of which were of a form of Hemp Lime construction

Hemp in Restorative Farming

For some information on the relative “ecofriendliness’ of industrial hemp as a grain and fibre crop in comparison to other commonly grown crops see extract from article on www.northernrivershemp.org

Converting pasture to small and medium scale sustainable hemp growing http://www.northernrivershemp.org/organic-hemp-farming-notes/

Industrial hemp is exceptionally suitable for organic agriculture, and is remarkably less “ecotoxic” in comparison to most other crops (Montford and Small 1999b). http://www.northernrivershemp.org/articles/farming/ecological-friendliness-of-hemp/

 Fibre crops as alternative land use for radioactively contaminated arable land – Journal of Environmental Radioactivity Vol 81 Issues 2-3, 2005, Pages 131–141  Belgian Nuclear Research Centre, SCK-CEN, Department of Radiation Protection Research.  http://www.sciencedirect.com/science/article/pii/S0265931X05000160

The transfer of radiocaesium, one of the most important and widespread contaminants following a nuclear accident, to the fibre crops hemp (Cannabis sativa L.) and flax (Linum usitatissimum L.) as well as the distribution of radiocaesium during crop conversion were studied for sandy soil under greenhouse and lysimeters conditions.
