CHECK IT OUT- - Glorious Mud! by Gus W Van Beek. Ancient and Contemporary Earthen Design.

In "CHECK IT OUT" posts we'll spotlight books on green subjects available at our own San Antonio Public Library. First up is "Glorious Mud" by Gus W. Van Beek with Ora Van Beek. This 500 page book, profusely illustrated with black and white photos, documents the investigations of the former curator for anthropology at the National Museum of Natural History into earth built buildings the world over.

Unlike other books on natural construction this book also looks into the ancient history of earth buildings. This is not a how-to book, it is more of a survey of earth building methods and their history. It might well serve as an inspiration to a modern builder to see the multi-storied mud brick buildings of Yemen or the the rammed earth houses of Germany. To hear that the longest lasting structures of ancient Egypt were made of mud might be give confidence to someone interested in rammed earth building today. Though Mr. Van Beek suggests at one point that perhaps "adobe" would be a more attractive word to use than "mud".

Ora Van Beek, travelling with her husband, was able to gain access to the female only interior quarters in muslim countries which her husband could not, this gives a new insight into daily life in present day Pakistan and elsewhere.

The sustainable building enthusiast will find much to enjoy in this book and will come away with a much broader understanding of the many methods of using earth for building. If only the pictures were in color. Black and white photos do not do justice to the beauty of these buildings.

This book is currently in the New Books section of the Central Library. It was given to the library in honor of Library Foundation board member, Lamar Spencer. Considering the book sells on Amazon for $99.95 checking it out free from the library is quite a bargain. You can even reserve it online.

San Antonio Roger Rasbach Mansion for sale (with pictures) (Post updated 12/2010)

(As of December 2010 this realtor still has the photos up and apparently it is still for sale.  With that beautiful little lake why doesn't the city buy it and make a beautiful park just where it is needed!).

Several years ago Roger Rasbach spoke at SAC and many members of our group were able to attend. In the 1950's and early 1960's his designs were frequently featured in House Beautiful, including several homes built in San Antonio. His homes at that time were classic mid-century modern with many features we would consider elements of green building today, including careful siting, passive solar, use of local materials and use of natural ventilation.

A 1961 San Antonio mansion of his design is currently for sale. This allows us to take a peek at it by way of the realtor's site.  Of course if you can talk your way into a tour of the $1,600,000 six thousand square foot, 5 bedroom 7 1/2 bath then that's another option.

Though the house near Callaghan and Vance Jackson has been renovated and changed quite a bit inside you can still see the exposed roof rafters, open floor plan, generous use of glass and local stone that marked his designs at the time.

Mr. Rasbach passed away July 30, 2003. Throughout his career he continued to develop his ideas. He became a pioneer of green building. His book "The Provident Planner" published in 1976 contrasted the improvident wasteful, inefficient and hard to maintain with the provident. He showed how to transform an improvident home into a provident one.


His newly built  Provident Homes included Thermasave SIPS for insulation and steel framing to deter termites.

December 2010 Addition.
This post is getting some hits this month perhaps due to the offer for sale of a 1965 Rasbach home in  Rollingwood Texas.

So I thought I'd add a little bit to it off the top of my head.

I'm no Rasbach expert but I did hear him speak, look at some of his House Beautiful designs and read the Provident Planner. Advertisement for the Provident Planner in Texas Monthly via Google Books.


To my knowledge, Mr. Rasbach's designs from the beginning to the early 1970's seem to have included lots of glass in a typical Mid-Century style.  His rule of thumb for a Provident Home though was that it should have l0% or less fenestration, which is a far cry from his early work.

He advocated built in furniture, which is in line with his modernist background.  He argued that built ins made for easier cleaning.  Ease of cleaning is also why he advocated wide baseboards and door casements.  He suggested that light switches be placed in the woodwork surrounding doors because such glossy painted surfaces would be easier to clean of the inevitable finger prints.

He didn't like the idea of people taking time out of their lives to paint and repaint walls.  

His advice on flooring differed from today's green architects.  While he advocated for permanence in driveways, he did not seek permanent interior flooring. (He wanted permanent concrete drives rather than temporary asphalt ones.)

Inside he suggested that a sacrificial surface be used in high traffic areas.  Vinyl or rubber floors in the kitchen and hallways which could be replaced as needed while providing an easy to clean and relatively soft surface was his suggestion.

Green Camp SA, Saturday May 9, 2009: An Unconference. Learn from and teach your green peers, exchange ideas and start solving problems.

Green Camp San Antonio, May 9 2009 , 9 to 4 at the Pearl Stables on the renovated and reused Pearl Brewery grounds will be unlike any conference in San Antonio this year.

In fact the organizers call it an "unconference and a gathering of people to share & learn in an open environment with discussions, demos & interaction." Admission is free but you will need a ticket, which you can get from Eventbrite. Volunteers and donations are also welcome.

When you sign up for your ticket you will be asked for three topics you most want discussed at Green Camp. You will also be asked what presentations you could make. It isn't a top down event. The agenda is determined on the day of the event.

The Green Camp unconference is modeled on PodCamp which focuses on new media and BarCamp which focused originally on web applications but whose concept has been applied to explorations of public transit, health care and political organizing. PodCamp San Antonio Dos took place in May of 2008.

Classic Australian Hills Hoists Clothelines now available in the USA

The Hills Hoist rotary clothes line is a icon of Australian life. Though often imitated, the Hills Hoist has the reputation as the very best in outdoor rotary clothes lines. But they have only been available in the USA on a very limited basis, until now.

The hoist features a geared cranked lift that raises the unit so that your clothes can catch the breeze. It is also designed to allow you to remove the unit from the ground so that your yard is not permanently graced with a spinning clothesline.

Currently they are available on line from breezedryer.com and from other purveyors reached through the official US site linedryit.com.

Here are some reasons to give line drying a try: (Provided by Hills)

• Line Drying Saves Energy: Second to the refrigerator, the electric dryer is the second biggest household user of electricity. According to the Association of Home Appliance Manufacturers, as of 2005 there were 88 million dryers in the United States. Each of these consumes approximately 1,079 kilowatt hours of energy per household, emitting 2,224 pounds of carbon dioxide. Every individual who chooses to do one less dryer load makes a difference.
• Clothes typically last longer without the duress of a machine dryer.
• Exposure to sunlight is the best natural bleach for your clothes.
  
• Line Drying kills germs: The sun's ultraviolet rays are an antiseptic and kill bacteria.
• Line Drying is perfect for things that can't go in the dyer- rubber backed throw rugs, car mats, extra large blankets.
• Line Drying inside on a retractable or folding clothesline is a great humidifier for your plants, skin and hair.

Line drying tips:

• Shake out clothing before hanging to diminish wrinkles.
• Hang shirts and tops from the hem or tail so clothespin marks don’t show.
• Add vinegar to the rinse water (1/2 cup per load) to prevent any drying stiffness. Vinegar removes soap residues that cause stiffness and, as the clothing dries, the odor disappears so you don’t have to worry about smelling like a pickle!

FIRST EARTH documentary offers views of notable and beautiful natural buildings

FIRST EARTH- Uncompromising Ecological Architecture is a new documentary to be on the look out for if you have any interest in the beauty of natural architecture and in the possible implications of more widespread building with earth.

The segment from youtube below entitled "American Earth" includes view of Taos Pueblo and interviews with, Meka Bunch of Kleiworks and natural builder artist, Sun Ray Kelly, who designed the new structure on Chapel Hill at the Kerrville Folk Festival site. (Photo by Peter and Hui-i Morehead of Earth Passengers.org in Taiwan.)


The documentary is currently being screened at festivals and special events. The documentary website has wonderful galleries of natural buildings on four continents.

COB WORKSHOPS.ORG, points you to Cob Building workshops Worldwide

If you have time, money and the willingness to travel the world to learn cob building, then Cobworkshops.org can point you to a variety of workshops. They specialize in cob and do not list workshops related to other styles of natural building.

Begun by Coenraad Rogmans and James Thomson of House Alive! Natural Building and now maintained by Michael Blaha of I Love Cob, the site currently lists events on both coasts of the US and Canada, Mali in west Africa, Hawaii and France.

The site also has links to a number of cob building related sites and to news items related to natural building.

Why is Rainwater Collection so legal in Texas and so illegal in Colorado?

In Brad Lancaster's Rainwater Harvesting Basics YouTube video, he mentions that in Arizona though rainwater collection was illegal people collected it anyway, and the laws that made it illegal were changed. Perhaps you might think that rainwater catchment was illegal because of some concern or another about cisterns, but according to an article in the LA Times, collecting rainwater off of one's own roof in Colorado is illegal and considered to be stealing water that belongs to someone else.

Powerful lobbies oppose changes in Colorado water law that would allow rainwater catchment. They see the water that falls on a roof as already being part of a waterway whose flow has been allocated.

Water law generally is complicated and Texas water law is no exception, but the simple reason rainwater catchment was not a big legal issue in Texas is that though the state controls natural surface waterways, rainfall is not considered part of the waterway until it joins it. Landowners can reasonably capture and use rainfall before it joins a natural stream, creek, river or lake. Though we have plenty of issues for our legislature to fight about, thankfully rainwater catchment is not one of them.

So, legal rainwater harvesting is yet another reason to be glad to be a Texan.

A useful site that could be used more: the Sustainable Building Exchange

Imagine if a site existed where you could post requests for sustainable building materials like straw bales. Imagine if a site existed where you could tell people about sustainable building materials you have for sale or to give away. What if that site had a special section just for San Antonio?

Of course some people would say such a site would be called Craigslist, but actually the Sustainable Building Materials Exchange is specifically intended to facilitate the exchange of information on green, recycled and sustainable material. They have sections set aside for various cities including San Antonio. A recent post in the Austin section gives information on collecting free glass mulch from the City of Austin.

Solar Power Offer from Novastar Energy

We are in the middle of a whirlwind of news regarding energy efficiency, federal tax credits from the stimulus package, the new ordinance coming from the Mayor's Mission Verde program, and the expected re-instating of the customer rebates in May. Each one of those deserves a blog post or two on their own merit. Meanwhile, a local supplier of renewable energy systems, Novastar Energy has announced a price breakthrough for turnkey photovoltaic systems. To summarize, Novastar will help you determine what solar capacity choices you have. Once you have decided the capacity best for you, Novastar will design the system, you purchase the components at cost, "manufacturer pricing," and installation cost to you is $700 per kilowatt installed. Installation includes all the required permits.

As with any projects mentioned in the blog, practice due diligence and look into this offer for yourself. This offer is for a very limited time, so if you are the least bit interested, go to the Novastar Website or call them at 210-391-4009.

Labyrinths: a quiet path that can add another dimension to your outdoor space

When you plan your outdoor space you might immediately think of a patio, an outdoor kitchen, a quiet place for relaxation, flower or vegetable gardens. But the outdoor labyrinth is an option you might not have thought of.

A modern labyrinth is a pathway that is walked for relaxation and renewal. It is not a maze. The only thing a labyrinth walker can get lost in is their own thoughts. Labyrinths can be as simple as a path or elaborately hardscaped. They can be lined with flowers or placed in the grass.

They can be laid out by hand or with the aid of commerical templates. Flickr has a collection of labyrinth photos for inspiration.

Boerne Sustainable Concept House owners share their home with the public

Some people who build an interesting house don't want anybody to know about it. Some people are willing to be on a home tour. Some even do a personal blog detailing the process. But Karen and Griz Adams of Boerne, Texas are going the extra-mile on their Sustainable Concept House to let people in on the process of building and in experiencing the results.

In July,when their sustainable home is completed they will host a week long open house to benefit the Cibilo Nature Center, which for three years will then coordinate continuing education programs for both architects and the general public including field trips to the house Topics will include solar energy passive and active, sustainable building materials, rainwater harvesting, gray water and LEED residential certification workshops. Already the Cibilo Nature Center has hosted one workshop. Another is planned for May 23, 2009 which will include a visit to the site.

The house is scheduled to be included in an AIA home tour in Fall 2009.

Karen, a PR consultant by trade, regularly updates an Express-News blog, Green Dream , on the process of building the house. Once they found the materials they wanted to use they contacted suppliers and used the power of possible good publicity to negotiate good prices. A medical diagnostics company will be performing a study to examine how a healthy home can impact health.

Ben Adam, AIA designed the 3500 sq foot home which will house the family of four and Karen and Griz's offices. Karen said they chose to go with 2 by 6 stick framing to show that mainstream construction methods, if done right would result in an energy efficient, healthy sustainable home.

The house which is on an infill lot in Tapatio Springs will be connected to the subdivision's sewer but not to their water. Rainwater catchment and gray water reuse are expected to meet all their water needs. The house will include passive solar design, a solar hot water heater and geothermal air conditioning.

The house is intended to achieve LEED Platinum status.

Who said sidewalks had to be concrete? California company produces recycled rubber sidewalks

In the old days side walks were wooden. Even today some sidewalks are made of marble or decayed granite. But a California company, Rubbersidewalks Inc wants to get us walking on recycled rubber.

They manufacture rubber sidewalks which they say save money compared to concrete because they are easier to replace and repair. Because their rubber sidewalks accommodate tree growth better, they save trees. They keep tires out of the landfill too.

They come in gray, black and terracotta. The sidewalks are modular and can be opened by a contractor for tree root maintenance, utility work and relocation. They perform well in cold temperatures. Rubbersidewalks, at 0 degrees F for 48 hours, were subjected to repeated impact testing. Samples exhibited no signs of crazing, chipping, spailing or cracks by inspection. They don't expand in hot weather and retain less heat than concrete.

Because of their post consumer recycled content and the way that they reduce renovation impacts they qualify for LEED credits.

BIG in JAPAN! International Dome House Ltd offers polystyrene plaster-coated modular dome homes and communities.

Some people want a house that looks like everyone else's. Some people don't.

Japan's International Dome House's modular polystyrene homes definitely don't look like everybody else's except when they are clustered in communities of them.

The houses are made from thick polystyrene and finished with plaster. They are assembled from off the shelf parts that make arched entrances, arched halls and hemispheric rooms.

They are heated and cooled with Japanese style mini-split systems and of course are very energy efficient and earthquake resistance. They feature an anti-oxidant solution that is said to foster good health.

In Japan they are considered a low cost alternative. Otaku International indicated that a basic dome has 475 sq feet and costs start at $30,000 without transport, assembly, wiring, plumbing, interior work or exterior and interior plaster. That means $63 a sq ft for an incomplete unassembled shell. They are not for sale in the USA.

Welsh powder press invention turns waste wood, waste metal and plastics into bullet proof panels and more.

In the SASL we've long heard about the benefits of grinding construction waste on site. Such ground waste can sometimes be used as mulch, aggregate or a soil amendment. At the very least grinding substantially reduces the volume sent to a landfill.

But September 26, 2008 a Welsh company Protomax Plastics announced the creation of the P2 Machine which goes far beyond any waste grinder in use to date. Its birth announcement got little notice in the US but if its promise comes to fruition it will have long reaching effects on construction and waste handling.

They say:

We have recently designed, built and registered a patent on the P2 powder press. The P2 takes mixed waste and turns it into useful products such as hoardings, partition walls, transport trolleys and even armoured panels.

The machine creates an outer skin of recycled plastic around a core of re-processed, sanitised mixed waste. The waste is reprocessed with a special formula, which makes it foam and create a solid light- weight panel or product. The waste can include elements of metal or wood, alongside plastic bags, bottles and industrial plastics.

Each panel or product can be made up to customer specification, the P2 machine can produce a simple foam filled panel, or a bullet proof door with all ducting and necessary fire ratings required by the customer. Both products would use a high level of mixed waste

This means that it would no longer be necessary to waste wood for hoardings (Construction Fencing )or shuttering, and then throw it away. Panels can even be coloured and contoured for shed roofing or partition walls.

The machine is mobile and could be used to produce modular emergency housing in crisis areas, where the locals could re-use much of their own resources. Medical waste has always been difficult to dispose of, particularly in 3rd world countries. The P2 method can re-process this material into sanitized products. Billions of used syringes need to be disposed of each year safely; there is now a method to do this.

Linoleum the misunderstood floor covering. It's historic, healthy, resilient, beautiful and Sustainable

Perhaps more people misunderstand linoleum than any other flooring material. It is thought to be modern but has been used in houses since the 1870's. Many people think of it as first cousin to vinyl but instead it is a combination of basic natural substances. It is easier on the legs than hardwood flooring, and healthier than carpet for allergy sufferers.

In San Antonio, if you visit the historic Steves Homestead which was built in 1876 you won't find the linoleum on the floors which was there when the house was built. The restorers just couldn't live with covering the wood sub-floor with the historically accurate linoleum. But today as much as wood floors are loved, more people are appreciating the style of linoleum.

The basic ingredients of linoleum include flax seed oil (aka Linseed), ground wood, ground cork, pine rosin and ground limestone. With the exception of limestone which we in south Texas know to be plentiful, they are all renewable and biobased.

For people who are sensitive to lab created substances, linoleum can be the solution. Linoleum doesn't harbor the dust mites that plague many allergy sufferers.

Modern manufacturers of linoleum include Armstrong and Forbo Marmoleum.

Forbo offers elaborate border and corner designs in both vintage and modern styles.

Castor Oil adds bio content to Icynene insulating spray foam

If you are of a certain age you might remember castor oil as a cure-all that your grandmother prescribed for good health. Now Icynene has come out with LD-R-50, a water based insulating spray foam formula that uses castor oil to reduce the need for petroleum based polyol and which has a mean biobased content of 8% (+/- 3%) according to the International Code Council (ICC).

According to Icynene the castor bean has several advantages. It is grown on non-irrigated, marginal land which generally would not support food crops. The company says that production of castor oil has "low energy dependence". It can be harvested manually and does not require treatment with pesticides or fungicides. The castor bean itself has an oil yield of 40%.

Icynene LD-R-50 has been added to the USDA's Biopreferred catalog and can contribute to achievement of LEED and NAHB NGBS designations. It is also the first product for which a product report is available online from the ICC's Sustainable Attributes Verification and Evaluation program.

USDA brings BioPreferred Showcase to San Antonio June 9 to 11, 2009

According to the Department of Agriculture (USDA) website, up to 10,000 government procurement professionals will be in San Antonio for the US General Services Administration's Expo 2009 June 9 to 11. In conjunction with the expo, the Dept of Agriculture will host the 2nd annual BioPreferred Showcase and Training.

Training session topics will include information on what makes a product "green" and how green qualities are measured, stories of Federal employees who have used biobased products for sustainable design, construction and renovation and those who have used bio-based products for sustainable maintenance as well as a look at the impact of biobased product government purchases on the economy, jobs, energy security, and the environment.

The GSA Expo 2009 is a free training conference and exposition meant for government officials and employees whether local, state, federal or military who influence or make government purchases.

The BioPreferred program was established as part of the 2002 Farm Bill. The USDA is in the midst of a process that will eventually lead to the authorization of products to bear a distinctive BioPreferred label.

Currently the Department maintains a catalog of BioPreferred biobased products particularly to help government buyers purchase bio-based products . Products on the list include office supplies, building materials, housewares and even toiletries.

Gray Wolf Earthship near Leakey for Sale

The magnificent 3500 sq foot earthship on the 800 acres of the Gray Wolf Environmental Education Center, Inc. and Land Trust is for sale at $350,000, with most furnishing included. But you might be too late to purchase as the Pioneer Real Estate site states a sale is pending.

Long time members of the SASBC (SASL) fondly remember trips to see the earthship and the other sustainable residences built on this beautiful piece of the Hill Country. With numerous springs that run into Mill Creek which itself feeds the Frio, the land is flush with flora and hill country animals life.

Gray Wolf is a land trust. Members purchase the right to build on land approved by the other members, but the land is held by the trust. The members approve the structures to be built. As a group we haven't visited there in at least five years but several years ago in addition to the earthship, people were working on rammed earth, stone rubble and log structures. Water was being collected in spring boxes and a small kitchen area was available for the use of people building their homes.

This earthship has the features readers of Michael Reynold's books all know about. In this photo you can see the kitchen sink planter and the entrance to the cold room for food storage.


In this photo you can see the New Mexico style viga beams and the classic earthship decorative touch, a glass bottle design embedded in an interior wall.


The couple who built the earthship were incredibly industrious. The process of building an earthship is manual labor heavy to begin with but they did much more. Even after their home was finished they added a stone patio worthy of the Civilian Conservation Corps.


There may be other earthships in south Texas, but to my knowledge, they've never come to our attention at SASL. If you know of any please let us know. Perhaps someday soon we'll be able to visit the Gray Wolf Environmental Education Center, Inc.. If you are interested in organizing or joining such a excursion, please join our Facebook group or come to our monthly meeting at Whole Foods.

A Hole in a Fence -- a rumination on change and development in a unique Brooklyn neighborhood

"A Hole in a Fence" a documentary by D.W. Young is a consideration of change and development in a small corner of Brooklyn, New York. The Red Hook neighborhood of 10,000 people has seen better days. A percentage of the population lives in extremely large scale housing projects, while another large percentage lives in single family homes. The subway doesn't reach to Red Hook and there is room for cars. There is also room for the homeless on neglected and unused industrial sites.

Young focuses on one site, surrounded by a fence, which is very near the site of the planned IKEA super store. By coincidence he connects with Benjamin Uyeda, a young architect who specializes in green and sustainable design. But, while in college at Cornell he was given an assignment to do something about Red Hook. Instead of doing a master plan he built a little hut in this fenced property and documented it on film.

Young incorporates Uyeda's film and interviews with community activitsts to contemplate the effect of change on the community. It isn't a polemic. It doesn't present a plan. It is just observes and considers the situation.

The film is available on Netflix and for purchase from First Run Features.

Benjamin Uyeda is the chief architect for Zero Energy Design and FreeGreen.com which was discussed in a February 27,2009 post.

March's Monthly Presentation - Structural Concrete Insulated Panels

This month's presentation at San Antonio Sustainable Living will be given by a long time friend of our group, and a good friend of mine, Herb Nordmeyer. I depended on his expertise on a strawbale residence near Blanco, and his knowledge of all things concrete would be difficult to beat. He joins us on Tuesday, March 24th to introduce us to Structural Concrete Insulated Panels (SCIP's). That's right, another acronym to learn. Herb works as a Project and Technology Manager for Best Masonry. Herb is considered a leading expert on pozzolanic chemistry and formulating cementitious products with pozzolans. A pozzolan is an additive to the cement hydration process (a silicate type of material) that combines with calcium hydroxide to form calcium silicates. Okay, chemistry class is over. These additives improve the performance of concrete and the type of pozzolan determines how the properties of a particular batch of concrete change. The first pozzolan was volcanic ash, and probably the most talked about pozzolan around green building types is today's fly ash, a byproduct of burning coal for power plants or cement curing.
Don't go away. Herb will not focus on pozzolans, but he will introduce to many of you a construction process that we may be seeing more of in the near future. SCIP's have been around since 1970, and are commonly used in third world countries. While there are several versions, in general they consist of an engineered wire cage, insulation in the center and a cementitious skin on each side. With a one inch thick layer cement plaster on each side of a panel, it reacts not unlike a solid reinforced concrete wall. Structures can be built to resist 180 mile per hour sustained winds, California brush fires, Formosa termites, and many other disasters, all for the cost of a 2 x 6 wood stud structure. Not only are they economical and disaster resistant, they are extremely durable, can include recycled material, and reduce utility bills.
With the devastation on Galveston Island due to Hurricane Ike last year, the presentation Herb will make was developed to let code officials, property owner associations, and city officials know that there is an economical building system available that could have prevented much of the devastation. This month, we meet at our regular time and place, from 7-8:30 pm in the classroom inside Whole Foods Market (behind the wine & cheese section) in the Quarry Shopping Center. See you then!

LEED 2009 Compared to LEED 2.0

You can find a LEED 2009 Scorecard Comparison showing differences between LEED 2.0 and LEED 2009 on JustGotGreener.org. *

LEED 2009 is part of of LEED 3.0 and applies to commercial construction. The US Green Builders Council states in their LEED 2009 FAQ that the most noteworthy advancements in LEED 2009 include a process that will allow continuous improvement in LEED, a scientific re-weighting of credits to reflect the impact of environment on health, and the addition of regionalism to the program which will give bonus credits for items that are most important for a particular geographic area.

*“Just Got Greener” is a voluntary program encouraging businesses to take a hands-on approach that is not only great for the environment, but also for their bottom line. Just taking one step to corporate sustainable practices into your business, is one of the most powerful ways to make a difference both now and for the future.
