ECO-BUILDING – PART 12 – Electrics in a Straw Bale House

When having electrics in a straw bale home, one will need to know how to install it, as it might might be so that electricians will not necessarily have earlier experience with straw bale structures.

All of the wiring is to be hidden behind the plastered wall, or made to run in required places behind a special panel, so it is better to get it done right the first time. The panel solution also makes it easier to fix faulty wiring, if the need arises.

The wiring can also be placed to run in a tube which makes the installation easier.

ECO-BUILDING – PART 11 – Preparations for Plastering a Straw Bale House

A job well planned and prepared is a job half done. A quality plaster job starts before the plaster is brought to the site. The condition of the substrate, or the base surface to be worked with, is very important – as the plaster can only be as strong as the substrate it is attached to. Straw generally makes a great substrate for a plaster, as so does a mesh – if any mesh is to be used.

The transition points of bale to wood must also be detailed, because they have their own rate of expansion. Because these two materials expand and contract at a varying rate, many cracks will appear if the transition points are not properly detailed with a plaster lath.
.
plaster and wood transition points

One method is to cover all wood with roofing felt to isolate the wood from the plaster. One can also use a plaster lath to give the plaster something to hang on to. The plaster should always have some surface to hang onto, and hang on its own without any structural support. This is even more important around doors and windows as well as at the intersections with the ceiling.

burlapOn exterior surfaces, all wood needs to be covered as described above and any large gaps need to be filled.
Materials used for doing the filling are cob, light straw clay, burlap, spray foam (PU-foam) or other suitable materials.

When the plaster is to be applied, the walls should be tight and solid. All wooden parts should be covered and the mesh should be attached firmly to the wood structures and/or sewn through the straw bale walls.

All holes and gaps should be filled firmly so that no deflation occurs. It is also good to keep the site clean of straw and other debris, so one can walk safely around the structure.

The floors should also be covered so that dropped plaster will not have the possibility to mar it.

ECO-BUILDING – PART 10 – Working the Bales into Shape (continued…)

As an addition to the previous post: The nooks and niches in the walls can be made into various forms and for various purposes.

Nooks and niches are possibilities to remember, when you build straw bale houses

In this case too, only the imagination sets the limit.

ECO-BUILDING – PART 10 – Working the Bales into Shape

Cats loves to live in straw bale houses with smooth and beautifully curved windows and elements

A straw bale house is commonly equipped with soft curves. The advantage of having softer curves around the windows is that they allow more direct light to filter into the rooms while also acting as reflectors for indirect light. These curves are easy to make and have an additional effect on the aesthetics of the house.

Mesh

When a mesh is used for the engineering of a building, the creation of curves becomes quite easy. The mesh provides a form for the straw. The desired shape is created when the loose straw is placed behind the mesh, which is then nailed to the framing. For some shapes, such as curve around a window or door, additional plaster may be needed.

When using a metal mesh however, there is always the risk of creating a Faraday’s cage.

Niches and nooks

The characteristic of the walls being relatively thick makes it possible to create niches and/or nooks, if one desires. The spaces can be carved into the walls after the bales of straw have been stacked. They act as a decorative addition to on the walls, and can also be used to highlight an item in your home. These nooks can also be made into an ideal feature if a light fixture is attached to them.

These are a number of different options available as for the mesh – welded wire mesh, plastic mesh, chicken wire. It is worthwhile to experiment with various methods regarding to various usages.

ECO-BUILDING – PART 9 – Custom bales

A lot of custom trimmed bales are required in any straw bale home. The areas with windows serve as good examples. The task is to make a rectangular bale to fit. During the process one needs to know how to cut and retie bales, and how to notch and shape them.

Re-tying

The tip of a baling needleCutting the bales is not as easy as one would think. A bale of straw cannot be worked on as one would work wood. The bales have a tendency of breaking apart if not worked on in the correct manner. When working with bales one has to mark the bale where one wants a cut to be made and then proceed cutting the bale while incorporating a tool called a baling needle to retie the bale in parts where one will not be cutting the bale.

With a good baling needle you can retie a bale and create two custom bales from one in a short amount of time. The most important knot to know here is the Miller’s knot.

Notching and shaping

Notching and shaping require the use of a chainsaw and a can of spray paint to make the markings of where you need to cut. Notches might be needed to fit the posts and other framing components. A time-saving method is to slightly over-cut the needed part for the posts and then stuff the space with straw if needed. Be careful not to cut the string of the bales while notching. Some notches can be more intricate than others.

ECO-BUILDING – PART 6: DESIGN REQUIREMENTS FOR STRAW BALE

Design Styles

Before the final decision is made, many variables have to be considered before that final design, such as weather conditions. If there is a lot of rain in the location – either seasonally or throughout the year – a home designed for a place which gets little or no rain may not be the appropriate option for the design. The style and details of the design is important for the efficiency of the home, so this should be considered thoroughly and with time. This is a process which should not be rushed and the characteristics of the property should also be taken into consideration.

Visiting and evaluating the site and property

It can be considered vital to understand the property before and during the design-process. If there are no hurries in the design, one has the opportunity to study how the land interacts during the year. One could discover later on during the project that the location is a wind tunnel for most of the year or that some other place would have suited better in terms of solar power and ventilation.

All this is found out through experience.

Water considerations

Pay attention to how the water flows on the property. Study if there are any bodies of water which are influential to the planning and find out how they behave. What is the situation of the ground water? – and if you are not connected to the network of the city, what are the possibilities of building a well?

Some points to consider are also the leach field for the septic system, and where and how the grey and black water is treated.

The well for drinking water must be situated a safe distance away from these and it might be best to keep the well uphill from the drain field where waste water is drained to. These are one of the reasons why topographic knowledge of the topography is essential in the planning.

In addition, a possible field should be close enough to minimize costs.

Solar trackingsolar panelo and sun

The sun is vital for an efficient home. It is possible to harness the suns energy for electric and heating needs. How does the sun behave towards the land during the different times of the year? These points affect the size and need for the roof overhangs of the building and the placing of solar panels. Further investigating comes in regarding the trees, prevailing winds and the sloping of the land.

Other aspects on design

When you know your land and the positioning of your house, it is time to start designing. Pay attention to window placement and size, since these affect the heating costs. Straw bales are ideal for sound proofing and for insulation, so this information with additional info on light and ventilation creates balanced results.

It is more economical to design with the land: taking in mind to topography, water wind, the possibilities with solar issues and flora. It is also more beneficial to take into consideration to have the home as a part of the landscape.
