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. This indispensable manual is packed with all the information you need to determine whether hempcrete is 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. 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. Get the Essentials! Chris Magwood is a sustainable builder and designer specializing in green and natural building techniques, the co-founder and co-director of the Endeavour Centre, and the author of several books on sustainable building including Making Better Buildings, More Straw Bale Building, and Straw Bale Details.
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.

Design your own sustainable home Many people dream of building a beautiful, environmentally friendly home. But until now there has been no systematic guide to help potential builders work through the complete process of imagining, planning, designing, and building their ideal, sustainable home. Essential Sustainable Home Design walks potential homebuilders through the process starting with key concepts, principles, and a project vision that will guide the house to completion. Coverage includes: How to clarify your ideas and create a practical pathway to achieving your dream A criteria matrix to guide design, material, and systems decisions Creating a strong, integrated design team and working with professionals and code officials to keep the project on track from start to finish. Key building science concepts that make for a high-performance, durable building Primer on building logistics, material sourcing, and protocols to ensure that the initial vision for the project comes to fruition. One-page summaries and ratings of popular sustainable building materials and system options. Ideal for owner-builders and sustainable building contractors working with clients aiming to design and build a sustainable home. Chris Magwood has designed and built some of the most innovative, sustainable buildings in North America, including the first off-grid, straw bale home in Ontario. He is co-founder and director the Endeavour Centre for Innovative Building and Living and co-editor of the Sustainable Building Essentials series. Chris is the author of Essential Prefab Straw Bale Construction, Essential Hempcrete Construction, Straw Bale Details, More Straw Bale Building , and Making Better Buildings .
Using plant material as raw materials for construction is arelatively recent and original topic of research. This bookpresents an overview of the current knowledge on the materialproperties and environmental impact of construction materials madefrom plant particles, which are renewable, recyclable and easilyavailable. It focuses on particles and as well on fibers issuedfrom hemp plant, as well as discussing hemp concretes. The bookbegins by setting the environmental, economic and social context ofagro-concretes, before discussing the nature of plant-basedaggregates and binders. The formulation, implementation andmechanical behavior of such building materials are the subject ofthe following chapters. The focus is then put upon the hygrothermalbehavior and acoustical properties of hempcrete, followed by theuse of plant-based concretes in structures. The book concludes withthe study of life-cycle analysis (LCA) of the environmentalcharacteristics of a banked hempcrete wall on a woodenskeleton. Contents 1.
