The essential guide to hempcrete - a strong, versatile, environmentally friendly, energy-efficient natural insulating material Hempcrete is a versatile, energy-efficient natural insulation material, useful for walls, roofs and floors. Made from the inner stem of the hemp plant mixed with a lime-based binder, it is a very strong, lightweight and breathable alternative to manufactured insulations. Essential Hempcrete Construction is a fully illustrated practical guide to this affordable, renewable method, from procurement to finishing. Going well beyond the scope of many natural building books, this indispensable manual includes a complete introduction to hempcrete, packed with all the information you need to determine whether it's the right choice for your project. It covers: Material specifications, testing and building code references and climate data Detail drawings for design reference Tool lists, and complete step-by-step instructions for mixing and placing hempcrete Finishing and maintenance techniques Budgeting and labor estimates Additional resources. Essential Hempcrete Construction is part of New Society's Sustainable Building Essentials Series. Series editors Chris Magwood and Jen Feigin have scoured the world of sustainable building to bring you the techniques and systems that deliver measureable benefits in terms of greater energy efficiency and reduced environmental impact. Written by the world's leading sustainable builders, designers and engineers, these succinct, user-friendly handbooks are indispensable tools for any project where accurate and reliable information are key to success.

A comprehensive practical manual for professionals and self-builders, this innovative book explains the many benefits of building with hempcrete. Hempcrete is a building material with excellent, environmentally friendly properties. It's made from lime and hemp shivs (a waste product from hemp fibre growing) and can be used for walks, floor and roof insulation. Hempcrete is breathable, absorbing and emitting moisture; this helps regulate internal humidity, avoiding trapped moisture and mould growth, and creating healthier buildings. It provides excellent acoustic and thermal insulation, and it is lightweight, which reduces construction costs. Whether you're working on a new build or are planning a renovation, The Hempcrete Book tells you everything you need to know to get started with hempcrete. It describes how to source and mix it, and provides a detailed account of construction techniques, highlighting potential pitfalls and how to avoid them. With fully illustrated design notes and examples of completed builds, this book is a powerful tool for any eco-builder.

Building with Hemp has been an inspiration for architects, builders, community activists, students and teachers around the world and as this construction system is gaining in popularity this edition will be even more important in assisting the uptake of this technology internationally.

“All of the essential knowledge for completing a successful rammed earth project. Written by a geo-technical engineer with experience ramming earth.” —Kelly Hart, author, Essential Earthbag Construction Everything you need to know to build with rammed earth in warm and cold climates. Rammed earth—sand, gravel, and clay or lime/cement binder packed into forms—is a low-energy, high-performance building method, yielding beautiful, sustainable results. It’s thermally stable and can be insulated, can actively modulate humidity, provides a healthy indoor environment, and allows site materials to be used for major structural and building envelope elements. Essential Rammed Earth Construction covers design, building science, tools, and step-by-step building methods for any climate, with a special emphasis on building in cold climates of the northern US, Canada, and northern Europe. Coverage includes: Overview of earthen building Appropriate use of rammed earth walls Stabilized versus raw rammed earth Design considerations, including structural, insulation, and building envelope details Special considerations for cold and freeze-thaw climates Construction drawings, with step-by-step building instructions Tools and labor covering industrial methods, low-tech techniques, formwork options, mix design, budgets, and schedules Codes, inspections, and permits. This guide is an essential resource for experienced builders, DIY home owners, designers, engineers, and architects. “A much-needed and science-based update to a North American audience of designers, engineers and builders.” —Bruce King. P.E., author, The New Carbon Architecture “ A great book for anyone who wants to deepen their technical knowledge of rammed earth walls systems. It’s very helpful to have a book on rammed earth that is more focused on engineered rammed earth walls for cold climates.” —Clifton Schooley, Clifton Schooley & Associates, Rammed Earth Designers and Builders

Sustainable building from the ground up - the pros and cons of the latest green and natural materials and technologies

The first highly illustrated, comprehensive guide to light straw clay - a high performance, low-impact, durable building material Light straw clay - straw mixed with clay slip - is a versatile, easy-to-use wall building material. Also called "slip-straw", its durability has been proven in beautiful, centuries-old buildings across Northern Europe and in modern high-performance buildings in North America. Building code compliant in the US and using "waste" materials with high insulation value and excellent moisture handling qualities, it's both high-performance and low-impact. Yet until now, there has been no practical guide to using the material in a wide variety of construction and renovation projects. Distilling decades of experience, Essential Light Straw Clay Construction is a fully illustrated step-by-step guide, ideal for both the DIYer and professional designer and builder alike. It covers: Material specifications, performance, and when and where to use it Estimating quantities, costs, and sourcing Illustrated, step-by-step guidance for mixing and installation, including "slip-chip" variations Detail drawings for various wall systems including stud, timber, and pole framing, Larsen trusses, I-joists, plus retrofits Code references, compliance, and best practice Finishing and maintenance techniques Additional resources. Lydia Doleman , a licenced contractor, taught carpentry and natural building at Solar Energy International in Colorado and was lead ecological builder for Portland's City Repair project. She's created beautiful, high-performance, low-impact buildings across the Northwest, from Portland's first permitted straw bale home and The Rebuilding Center's cob entryway, to a 3,300-sq. f light clay straw brewery. She's written for The Last Straw Journal and Permaculture Activist and appeared on NBC News and HGTV's Off Beat America . Lydia lives in southern Oregon.
