Press Release: Prototype House Becomes First Passive “Hemcrete” Home in the World

Wednesday, November 25th, 2009 by Billy Schweig

Asheville, NC–The Nauhaus Institute (NHI) is scheduled to begin the installation of its revolutionary hemcrete walls on its prototype research home this Wednesday December 2nd. Because a small part of the wall system was installed as a demonstration on November 12th, the prototype home is already the first of its kind in the US. The material, called Tradical® Hemcrete®, is made from waste hemp shiv and a lime-based binder. Designers from NHI have opted to pursue Passive House certification which would make the house not only one of the fist ten certified in the US but also the first Passive House hemp home in the world.

“This is going to be a really significant project on a global scale,” said Ian Pritchett, the Chairman and Technical Director of Lime Technologies who manufactures Hemcrete®. Pritchett flew in from the United Kingdom to mark the event. (see the full interview here – Youtube).

Designers of the home say that the new material will not only create breathable, long-lasting walls but also give the home an insulation performance of three times what building code requires. The material can be mixed and poured in to forms in a similar fashion to concrete.

“We’re essentially building with a bio-composite made from agricultural waste and a recyclable binder,” said Tim Callahan, Architectural Designer for NHI. “The lime binder itself has been used as a building material for thousands of years.”

The construction project has already raised eyebrows nationally in the green building world. “It’s going to be off the scale for LEED points,” said Pritchett. “This is a very big deal.” LEED stands for “Leadership in Energy and Environmental Design” and is the dominant rating system for environmentally sustainable construction. And it doesn’t stop there; the NHI team is projecting that the house will break records in nearly every quantifiable sustainability standard by which homes are measured.

“We sought out this home because it’s had a reputation as a historic project,” said Matt Schillig, owner of WNC ProBuilt. Schillig is installing the Hemcrete®, framing and Eco-Panels roofing on the prototype home.

The Nauhaus Institute is the research, education, and information-generating branch of the Nauhaus family of organizations based in Asheville, NC. The goal of NHI is to merge the best of modern high tech building science with the core principles of the “natural” and “green” building movements.

There’s been a lot of the “sexier” components being put together in the Nauhaus Prototype as of late. Ian Pritchett of Lime Technology flew in from the UK to oversee the installation of the first Tradical® Hemcrete® wall on a home in the US and what he says will be the first Passive Hemcrete® home in the world. Ian and his US partner Mario Machnicki trained Asheville builder extraordinaire Matt Schillig of WNC ProBuilt in Hemcrete® installation.

At about the same time, we’ve had Mark Prudowski of Lightning Bug Electric (more info here) finishing up the electric on the prototype home. Mark and his team, including a graduate from Asheville GO (the awesome non-profit we mentioned in our previous post), fitted the home with “smurf tubing,” ideal for wiring through bio-cretes and other cellulose-based walls. The design will allow for (more…)

Asheville GO and the Nauhaus Institute Join Forces for a Day-Long Work Session

Wednesday, November 4th, 2009 by Billy Schweig

The Asheville Green Opportunities (Asheville GO) Training Program came down to the site today to learn about the project and get their hands dirty with a work day. Managing Director Clarke Snell toured the team around the prototype site while Mike Figura toured them around Gaia, our sister urban ecovillage project, just across the creek. The rest of the day was spent building scaffolding to erect the roof structure and a box to help weigh waste material for LEED certification. See pictures after the break.

We attended an informal brainstorming workshop with federal officials representing Housing and Urban Development (HUD) the U.S. Department of Agriculture (USDA), Department of Labor, the Environmental Protection Agency (EPA), Department of Transportation (DOT), green-collar workforce developers, and urban planners. The meeting was held with hopes of launching a number of demonstration projects and pilot projects in support of the Sustainable Communities Partnership in Western North Carolina. We’re excited to attend the first of these conversations about sustainable communities and how government agencies can participate.

Press Release: Nauhaus Institute Teams Up With Kleiwerks, Creates Nonprofit Project

Thursday, October 22nd, 2009 by Billy Schweig
Asheville, NC–The Nauhaus Institute (NHI) has teamed up with Kleiwerks International to form a nonprofit partnership to oversee and fund the research, education and information-generating activities of NHI. The project will create a means by which to fund important data production and research currently being done by NHI in the area of ultra high-efficiency green building science. NHI is now in the process of building a prototype home in West Asheville that will be monitored and analyzed for energy efficiency, air quality, water conservation and a myriad of other factors. NHI members hope to use this data and the administrative help from Kleiwerks to create a working body of sustainable building information for everyone to use.

“Our goal is simply to improve every aspect of US buildings: health, comfort, durability, efficiency, livability, affordability, and self-sufficiency,” said NHI Managing Director Clarke Snell. “Our broader context, however, is climate change. If we dial all those variables into an integrated design building system, we can drastically reduce our carbon footprint, but a few hipster companies like ours creating radical buildings won’t get the job done. We all have to do it.”

Once completed the prototype home that will be inhabited by NHI member engineer Jeff Buscher and his family. This will not only allow detailed performance monitoring, but regular public educational tours of the unique home and landscape.

“We’re excited to see this come to fruition,” said Kleiwerks Founding Director Janell Kapoor. “The addition of the NHI team means that we’ll be able to expand our efforts locally and nationally.” The new partnership will be focusing on research and education surrounding high efficiency building married with traditional (or “natural”) building materials.

“Kleiwerks already has a global presence using indigenous materials and this will allow us to bring a different building approach that’s even more relevant to North Americans,” said Kapoor.

“It’s our intent to export the technology of our building system and make it available for everyone,” said Snell.  “We’re serious about changing the way America builds, and this prototype is our group’s next step in a long dialogue about the sustainability of our built environments.”

Founded in 1998, Kleiwerks International is a 501(c)3 nonprofit that creates community-based education, demonstration and action through natural building and sustainable living solutions. The Nauhaus Institute is the research, education, and information-generating branch of the Nauhaus family based in Asheville, NC. The goal of NHI is to merge the best of modern high tech building science with the core principles of the “natural” and “green” building movements.

As of October 8th, 2009, the Nauhaus Institute (NHI) and its research, education, and outreach activities are affiliated with Kleiwerks International (KI). We’re all very excited to see this collaboration take place as it represents exactly the type of symbiosis that’s needed to make the respective goals of NHI and KI a reality. Founded in 1998, KI leads hands-on natural building and sustainability training both in Asheville and around the globe. As part of their education goals, KI has taken NHI on as a nonprofit project as we wait for our own 501(c)3 status to come through. This means that, in the meantime, we’ll be able to fund our research and educational programs through tax-exempt donations from the public. You can read more about this exciting development in our following press release on the subject.

Press Release: Nauhaus Group Breaks Ground on Historic Prototype Home

Tuesday, September 1st, 2009 by Billy Schweig

Asheville, NC–The Nauhaus Group has officially broken ground on its historic prototype home. The Nauhaus Prototype, or NHP, is pushing the envelope for sustainable construction in the US. The design for the NHP boasts a unique combination of energy efficiency, traditional (or “natural”) building materials and aesthetic appeal.

Members of the Nauhaus Group believe that the NHP is on track to be one of the first ten Passive House certified homes in the US, garner a LEED Platinum rating with points to spare, and be the first house in the US to utilize Tradical® Hemcrete® (an insulation material made from industrial hemp fiber) as its wall system.

Instead of a groundbreaking ceremony at that beginning of construction when there is little to see, organizers of the project decided to hold a “Carbon Capture Ceremony” later in the process of building.

“We thought it would be more appropriate because our building’s paradigm is constructive, not destructive. Considering the unique features of the home we decided to hold a public event at a time in the construction process when people could view and experience some of the more exciting highlights of the prototype,” said Michael Figura, one of the organizers of the event.

Whereas a normal groundbreaking ceremony might involve a commemorative shoveling of soil, organizers at the Nauhaus Group hope to time their November 6th Carbon Capture Ceremony to coincide with the actual installation of the hemp wall system so attendees can participate.

After years of planning, the NHP is slated to mark a prominent shift in the way people think about homes and building in general. “The strength of our approach,” says managing director Clarke Snell, “is that we draw from a variety of methodologies and perspectives. We’ve got high-tech systems working with low-tech materials. Art in league with science.”

It’s no secret that the Nauhaus Group is out to save the world.

“The Nauhaus prototype is only part of a growing movement in the US to act responsibly when it comes to our carbon footprint,” said Snell. “The result of our approach is not only the most efficient, low-impact, durable, healthy, beautiful and affordable housing system we can muster, but a system that will continue to change, improve and grow.”

The house is owned by the Nauhaus Group itself and will be open for regular tours, workshops and other visits upon completion. It will, in the meantime, be occupied by chief engineer Jeff Buscher and his family to allow for energy efficiency analysis, systems testing and other research before it is sold.

The Nauhaus Group is a newly formed organization composed of designers, engineers, and builders at the top of their respective fields in Asheville and beyond. The group engages in for-profit activities ranging from design to sales but is also in the process of founding the non-profit Nauhaus Institute to house research and educational activities such as the NHP.
