Abstract
Hemp lime is a composite construction material that can be used for walls, insulation of roofs and floors and as part of timber-framed buildings. It provides very good thermal and acoustic performance, and offers a genuinely zero-carbon contribution to sustainable construction. Hemp masonry is breathable and is able to absorb and emit moisture, leading to much healthier buildings. Comprehensive guidance on using this novel material for housing and low-rise buildings is given for the first time in this book, which is full of practical information on materials, design and construction. It is fully illustrated and includes case studies and design details, and explains how the use of hemp-based material can capture and store carbon dioxide in the fabric of buildings. The guide is the output from a Defra-funded study commissioned by the National Non-Food Crops Centre.



Review
Given the deluge of 'eco friendly' and 'zero-carbon' terminology being indiscriminately tossed about within the construction industry, it is a pleasant surprise to read a 'green building' book that is more than an ostentatious decoration for the coffee table. Bevan and Woolley have done an excellent job in making an important and innovative building technique accessible to both layperson and professional. If I had to recommend one construction book from 2008, this would be it.

Review quotes
Rachel and Tom have pulled out all the stops in producing a very comprehensive guide on building with hemp and lime. Professionally produced, carefully indexed with plenty of clear diagrams, photos and images, this is a practical, visually supported handbook for those interested in using this sustainable and renewable natural product in construction. & this is a remarkably thorough and engaging guide to the use of lime hemp construction and I recommend it highly.
