Lehmbau-Praxis

Earth is a natural building material that is at once traditional and modern. In recent years it has advanced to become a high-quality material. Its aesthetic qualities and character along with its beneficial effect on the indoor climate and general well-being are widely recognised. Of particular relevance are its environmental properties, for example the incomparably low energy balance of many earth building materials. As an authentic historical building material, earth is also widely used in the conservation and renovation of historic buildings.

Lehmbau-Praxis, written by Ulrich Röhlen and Christof Ziegert, provides an overview of the current state of the art of planning and building earth constructions and is an invaluable reference for architects, engineers, building contractors and tradesmen. Available in English or German.

Brittlebush

Brittlebush is an experimental Desert Dwelling designed by Simón de Agüero, a recent graduate of the Frank Lloyd Wright School of Architecture in Taliesin, Arizona. The open-air living space incorporates tensile fabric structures into its design to shelter occupants from the sun. A fireplace provides winter heating.

The majority of the material used for Brittlebush were recovered or found on site: 90% of the steel was salvaged from the school scrap yard, all of the wood used for the formwork was waste from a local renovation project, and the earth used for the walls was from on-site.

Tidal Resonance Chamber

As the first rammed-earth construct in the City of Tacoma, The Tidal Resonance Chamber provides a contemplative and relaxation space for users of the Center for Urban Waters (a LEED Platinum Marine research and analysis facility) . Aimed at serving as an instrument for perceptual synchronize with the natural rhythms of Commencement Bay, the chamber’s thick insulated earthen walls buffer out the heavy industrial sounds of the surrounding Port of Tacoma, and through a series of feed back pump operations the chamber’s water level mirrors that of the Thea Foss Waterway manifesting as a ratio-reduction.

Designed by Robert Horner, the Tidal Resonance Chamber’s main interior space has a trapezoidal footprint roughly 12’ x 18’. The fortified rammed-earth walls measure 8’6” in height, and rest atop a concrete foundation that measures 4’ in height. The chamber has a maximum filling capacity of 2500 gallons, which will fill at the highest of high tides. The interior of the chamber is filled with reclaimed granite curb fragments, river stones and will eventually populate with micro-organisms, barnacles and other aquatic lifeforms.

Terra 2012

The International Scientific Committee on Earthen Architectural Heritage (ISCEAH) and the Pontifical Catholic University of Peru (PUCP) are pleased to announce that the XI International Conference on the Study and the Conservation of Earthen Architectural Heritage, Terra 2012, will be held in Lima, Peru, from April 23rd to 27th, 2012. The main theme of the conference will be “Conservation of Earthen Architectural Heritage against Natural Disasters and Climatic Change” and more than 500 specialists in the fields of earthen architecture are expected to attend.

The conference will provide a unique and invaluable opportunity to discuss and exchange information on the latest advances in the research and conservation field. Moreover, participants will learn about the cultural identity of earthen architecture in Latin America and be able to observe firsthand conservation issues in Peru, a country with a long and rich tradition of construction with earth.

The San Isidro Labrador Chapel

The San Isidro Labrador Chapel is a collaborative effort of many people, the tangible demonstration of the cooperation of architects, engineers, craftsmen, peasants, creative people and students.

João Caeiro e Capurso Fulvio got together with Benito Guzman Canseco (President of the Consejo y Oaxaca Nopal Tuna, e Mayordomo de San Isidro in the years 2009-2010) to organize a series of courses to endorse people with the ability to build houses with noble materials from the region.

These courses, mostly hands-on, are addressed to people seeking to build their own houses, within a philosophy of low cost, high quality and contemporary design.

The first opportunity emerged in San Bartolo Coyopec, for the construction of a chapel for the saint patron of the cultivated fields, annually celebrated. The building was finished in may 2010.

Eddy Residence

Michael and Lisa Eddy dreamt of living in a home that was designed to showcase their love of nature and appreciation for the environment around them in Colorado. Designed by JCL Architecture, their fantasy home made of rammed earth is characterized by a continuous trellis that greets you at the entry and leads you through the warmth of the house and out into the open backyard towards the landscape beyond. Aside from being beautiful, the house incorporates passive solar strategies and high thermal mass. Proper roof overhangs and southern exposure were calculated to allow maximum solar gain in the winter while minimizing heat gain in the summer. The thermal absorbent qualities of the rammed earth walls and dark stained concrete floors on both levels stabilize temperature swings from night to day and mitigate the need to run an air conditioning unit during the summer. These features are then further supported by a high-efficiency geothermal radiant floor heating system as well as soy-based insulation in the roof and walls.

Adobe Homes for All Climates

Adobe Homes for All Climates: Simple, Affordable, and Earthquake-Resistant Natural Building Techniques, by Lisa Schroder and Vince Ogletree, is ideal both for first-time do-it-yourselfers and for experienced adobe builders seeking to improve their craft. Drawing on the experience of more than fifty major adobe projects since 1993, Adobe Homes for All Climates describes Adobe Building Systems’ patented reinforcement and scaffolding systems, showing readers how to construct adobe homes more easily and safely, and with superior strength, durability, structural integrity, and aesthetic appeal, as compared to earthen homes of the past.

Computer Modeling to Build Better Mud Bricks

Rammed earth and stabilized mud block or brick are cheap, easy to make, usually durable materials widely used for building homes and low-level structures, especially in developing countries. Despite their widespread use and long history, the structural properties of these materials are not well understood, so how they could be manufactured to better withstand destructive natural forces, such as earthquakes and weathering, remains a goal. Craig Foster, assistant professor of civil and materials engineering at the University of Illinois at Chicago, hopes a specially tailored set of computer models he is developing may provide the necessary answers. He has just won a three-year, $243,000 National Science Foundation grant to conduct the work.
