Featured Speakers

Keynote Speaker John Straube, Ph.D., P.Eng.

John Straube is a specialist building science engineer who has been deeply involved in the areas of building enclosure design, moisture physics, and whole building performance as a consultant, researcher, and educator.

Energy-efficient, healthy, durable and sustainable building designs are a general goal of his research which is often supported by advanced computer simulation, laboratory testing and full-scale natural exposure performance monitoring.

Considered an international expert in moisture-related building problems, his building science expertise has been applied to moldy roofs, failed masonry, leaky EIFS cladding, insulating Mongolian yurts, wet basements, rotting crawlspaces and attics, historically sensitive retrofits, and litigation support for buildings as diverse as commercial office towers, manufactured housing, and sustainable strawbale homes.

Although John has been tossing strawbales around since he was a boy, he has been interested in straw buildings for more than 15 years, conducting field measurements and computer models, as well as assisted in the design of SB buildings. Building science applies to all buildings, but it is especially important in natural materials and its application to straw results in slightly different results than the normal bricks and sticks construction.

John recently received the Lifetime Achievement Award in Building Science Education from the Consortium of Housing Research Centers.

Asahara. His crew works solely with natural materials, using the
unique tools developed through the centuries for such work. Upon
returning to the United States, she wrote the book “Japan’s Clay
Walls: A glimpse into their Tradition of Plastering” -- a simple and
detailed look at the tools and methods she witnessed for building the
traditional Japanese wall from base to center coat. While continuing

Will Johnson (with Andy deGruchy) ~ Natural Hydraulic Lime in Straw Bale Construction, One Builder's Japanese Influence

William Johnson is a self-taught builder learning from the books and buildings he encounters. Originally from Georgia, Will first gained experience building timber frame homes. He continued exploring different mediums including insulated concrete blocks and insulated concrete forms. Over a period of 20 years, Will’s building designs drew heavily on Japanese and European timber frame influences. He made his way to New York City and settled in the beautiful Hudson Valley just north of Manhattan.

Exposure to the WPA projects of New York City, the great mansions of the Hudson River and Long Island, the Dutch homes, the Frank Lloyd Wright Usonian Development and the mountain homes of the Catskills and the Adirondacks has been like a privilege of traveling through a living museum.

Will has gained notoriety in a number of publications for his unique approach to straw bale design and use of truly sustainable construction practices.

Andy deGruchy ~ Natural Hydraulic Lime in Straw Bale Construction, One Builder's Japanese Influence (with Will Johnson)

Andy deGruchy is a 1982 graduate of The Williamson Free School of Mechanical Trades located in Media, Pennsylvania. He received The “Key Award” for the advancement of Williamson Trade School’s founding ideals and he received their diploma as a Brickmason. He has owned and operated deGruchy Masonry Restoration for 28 years, which has been the focus of his craft company, which restores vintage brick and stone buildings. In 1999 Andy began importing certain types of limes for use in appropriately mirroring some of the successful components of masonry structures, which have lasted for centuries throughout the world. The word got out that Andy had such limes and he began the company LimeWorks.us in 2000 to distribute the materials which he imports for many applications including straw bale construction. Andy is on the ASTM committee that helped define the terminology used for the United States Standards for hydraulic and structural limes including the modified limes, which can be produced in any country of origin.

Derek Roff ~ Earthen Floors, with a little Lime, Oil and Insoluble Soap

Enamored of both traditional adobe buildings of New Mexico and innovative solar designs, I was excited to discover the possibility of natural insulation in the strawbale building revival in the early 90s. Since that time, I have striven to learn as much as possible about how to build healthful, appropriate, beautiful, energy-conserving natural buildings, and to help spread information on these techniques. I worked as an associate editor for The Last Straw Journal, helped with organizing six of the Build Here Now natural building/permaculture convergences at Lama Foundation, and served Builders Without Borders on their steering committee, as Director, and Co-Director. ’ve been privileged to learn from, befriend, and work with many of the most innovative natural builders.

Bob Theis ~ "Designing People Places"

Bob Theis wanted to be a planner until he found out that planners don't generally get to work on the details of how good places are created. While doing architecture, including some of the earliest straw bale buildings in California, he discovered that summer camps and retreat centers were as interested as he was in social fabric. He has since consulted with camps, conference centers, intentional communities and monasteries on their ecological footprint, and how they can function more like villages.
