Hempcrete Workshop at Yestermorrow Design/Build School

Dive into the world of plant-based building materials with Yestermorrow's introduction to Hempcrete, a bio-composite material created from the woody core of the hemp plant combined with a lime-based binder that can be used for construction and insulation. 

Trusted around the world as a robust, high-performance sustainable building system, Hempcrete entered the US market a decade ago and is poised to take the natural building industry by storm because it is non-toxic and flame, water and pest resistant.

Join us and learn how to make Hempcrete, and join a growing community of radically responsible industry stewards!

Instructors:

LEARNING OBJECTIVES

1. Summarize the history of hemp and hempcrete, the regulatory barriers in the US that are slowly easing, and describe examples from pioneers in hemp building from Europe and the first projects in New England.

2. Identify sources for hemp and lime, and explain methods for installation of this alternative material, the state of research internationally versus in the US, and what considerations are necessary from a code standpoint to build,

3. Use hempcrete as a monolithic solid-wall construction material for building carbon-beneficial envelopes as an alternative to current fossil-fuel based assemblies used in high performance buildings.

4. List complementary, low-cost material solutions to reduce toxins in the building and improve the healthfulness of a building
