Straw Bale: IntroductionDefinitionStraw bale construction uses baled straw from wheat, oats, barley, rye, rice and others in walls covered by earthen or lime stucco (some use cement stucco, but not typically suggested). Straw bale are traditionally a waste product which farmers do not till under the soil, but do sell as animal bedding or landscape supply due to their durable nature. In many areas of the country, it is also burned, causing severe air quality problems. It is important to recognize that straw is the dry plant material or stalk left in the field after a plant has matured, been harvested for seed, and is no longer alive. In contrast, hay bales are made from short species of livestock feed grass that is green/alive and are not suitable for this application. Hay is also typically twice the price of straw.

ConsiderationsThis technique for constructing walls has been recently revived as a low cost alter-native for building highly insulating walls. The technique was practiced in the plains states in the latter 1800’s and early 1900’s. Many of the early structures are still standing and being used. The technique has been applied to homes, farm buildings, schools, commercial buildings, churches, community centers, government buildings, airplane hangars, well houses, and more.

Straw is also being used as a building material currently in sheet materials such as sheathing and wall panels. However, the approach of using bales directly, despite its history, is a new technique from a regulatory standpoint. In the 1990s a number of cities passed a straw bale construction building code, followed by the state of Califor-nia.

Building walls with straw bales can be accomplished with unskilled labor, and the low costs of the bales make this technique economically attractive. However, it is important to realize that the cost of straw bales will differ depending on what time of year they are harvested and how far they need to be transported. They are cheaper at the time of harvest rather than after they have been stored from the previous season and, of course, cheaper if they are transported shorter distances. Bales must also be protected from getting wet. Costs also begin to rise when one considers the type of stucco and its application. An earthen plaster taken from site soil, applied by the owner/builder, and maintained by the owner is quite inexpensive, but may take a long time to apply. A cement stucco applied by a contractor is accomplished quickly and lasts a very long time without any maintenance, but also costs money. As with any style of construction, the more labor input by the owner and the less by the contrac-tor, the less costly it will be.

Two basic styles of straw bale construction have been used: post and beam construc-tion with straw bale infill, and structural straw bale construction or “Nebraska” style (the weight of the roof is supported by the bales). There are a number of straw bale buildings now located in the Austin area and local expert consultation and construc-tion is readily available. (See Resources)

TechnologyExperimentation with straw bale construction continues. A good deal of standardiza-tion and refinement in regard to techniques, tools, and associated materials is now appearing.

SuppliersStraw is plentiful in many locations. However, distribution systems are not developed for straw to be used construction.

CostThis can be one of the most economical wall systems. Houses have been constructed for as low cost per square foot (floor area) for very basic accomodations to high end homes at well over $100.00 per square foot. Building code acceptance will be key to obtaining conventional financing.

The cost of construction with straw-bales is comparable to wood frame construction. As the cost of wood rises, and bale systems are refined, straw bale will be less. When energy savings over time are factored in, straw-bale is the economical choice. One family in California’s hot Central Valley was able to obtain a higher mortgage for their straw-bale home by showing that their cooling costs would be substantially less.

Public AcceptanceThe appearance of a completed straw bale structure is similar to a southwestern adobe style building. This look is generally positively viewed . There will be hesitation among mainstream buyers to this technique at first since it is new and unusual. Sig-nificant interest in this type of construction exists in our region, although the adobe style is not typical for this area.

RegulatoryAny unusual building technology must be evaluated by the code enforcement author-ities before approval can be granted. This is typically done by review of another code agency’s approval or position on the technology or by review of test data supplied by a reputable independent laboratory.

In the case of straw bale construction, there are precedents of approval in other jurisdictions. Anyone wishing to receive approval should follow the local straw bale construction code. The inspections department in other areas can refer to the Green Building Program for locations of precedents from our as well as other building inspection departments.


Guidelines & Overview

Straw bale construction exhibits R values from R-30 and up to R-45. The bales are typically covered with concrete mortar/stucco or earthen/lime plaster, achieving a high degree of fire resistance. Two hundred million tons of straw are burned annually in the US. The stability and lack of weathering in straw is not desirable in agriculture but quite desirable in construction. Straw in straw bale structures has not shown evidence of termite infestations.

Dry bales should be used. Moisture levels in use and in storage should be below 14%. The bales should be kept dry after construction.Bales may be anchored to each other for stability while under construction using stakes of wood (1×2×36), rebar (#3 or #4) or bamboo that penetrate at least two bales. Another less popular method uses mortar or clay between bales. A new meth-od uses bamboo (or similar) stakes on both sides of the bales, tied with wire or twine, “corsetting” the bales. Such anchoring is generally accepted to be primarily necessary to keep walls from toppling during construction; well applied plaster will usually provide sufficient stability once complete – though by that time, whatever pinning method was used is embedded in the walls.

Bales can be used flat or on edge. They are best used flat for structural purposes. Plaster will also “key” into the ends of the straw when bales are laid flat, whereas bales on edge will have the long length of the straw on the wall surface, providing a weaker bond between the plaster and bale.

Bales come with two-wires or three-wires (or strings) holding them together. Two-wire bales weigh about 50 pounds and three-wire bales, 75-100 pounds. Two-wire bales are usually 14 inches high, 18 inches wide, and 32-40 inches long (typical in Texas). Three-wire bales are 16-17 inches high, 23-24 inches wide, and 42-47 inches long (typical in western states).

Bales should be firm and strung tightly with either baling wire or twine. Half bales and whole bales are needed so the bales are staggered when stacked.

A post and beam timber frame construction (or steel or concrete) can use bales as infill. The frame adds to the expense in materials and in labor for constructing it and then working around the frame with the bales. However, this approach will be more readily received by building officials.Window and door frames and headers can be made from wood. Windows and doors are typically accentuated towards the interior or (less preferable) exterior of the opening creating a deep well. Care is needed to if creating a deep well on the exterior to avoid water entering or collecting in these areas. Windows tend to be a point of failure due to water invasion, so they must be detailed carefully.

A wood plate or concrete beam (or bond beam) is placed on top of the wall. Trusses or roof framing can be set on this. A threaded bar can penetrate through the top bales and be fastened to the plate or beam for added roof stability

Poultry netting can be mounted on both sides of the walls for plastering, though it is no longer considered mandatory by many bale builders. Stucco lath is used around windows, doors, and corners for added strength. The wire netting and lath are typi-cally held against the bales by wire ties through the bales or “U” shaped pins into the bales.Utilities can be laid in the walls as they are built, laid against the bales after the walls are built or run in moldings, interior walls, under floors, or in the attic.

Structural/Load Bearing, or “Nebraska Style,” straw bale construction requires that the bales sit for a short period of time to complete any settling before stucco is add-ed, or that the walls be mechanically pre-compressed. If the bales are firm, there will be very little settling (typically less than 1 inch). A wire tie-down system which is con-nected to the foundation and the top plate, application of downward pressure using a front end loader bucket or similar, or any of a number of other techniques have the ability to firm up the wall and compress it to compensate for any settling concerns.

Approximately 10,000 acres of wheat and oats are harvested in the Travis County region each year. Eight to ten acres can supply sufficient straw to build a small house.

The best time to obtain straw is at harvest time, May through June in central Texas.

Straw-bale Construction

When considering ecologically sound construction methods and materials, few if any have as many layers of redeeming value as straw-bale construction. For starters, the raw material is 100% waste of another industry, the growing of grain for food, and in many cases is otherwise burned, causing serious pollution. The material is also pack-aged in a convenient and user-friendly form.

Straw-bale construction is a proven method of long-lasting durable building. Home-steaders in the Great Plains started building with bales in the late 1800’s, and many of these structures still stand today. Properly built and maintained, straw buildings can have a useful life span of at least 90 years.

Straw walls place all the wall elements in the right location. Protective layer on the outside, ample insulation at the the center, and thermal mass to the interior. These area the ingredients of high-performance wall systems, in this case utilizing natural, healthy materials. When laid flat and stacked like bricks in a ‘running bond’ pattern, a plastered or stuccoed straw-bale wall is ±27” thick and yields an insulating value of R-57. Stacked ‘on edge’, with straw parallel to the plane of the wall, similar insulation levels are achieved in 25% less width (±18”). The State of California has established R-30 as the accepted value, still several times the value of typical insulated wood walls.

Straw-bale can have great aesthetic value, and lends itself to a variety of styles and finishes. The thick walls present opportunities for niches, deep window sills and seating areas, and “truth windows”. The substitution of bales for lumber can relieve the pressure to log old-growth forests, preserving ecosystems for wildlife habitat, air-quality and soil-stabilization. And, as Matts Myhrman once said, “You can do any-thing with straw-bales, except have skinny walls!”


The Green Studio Handbook


Earth BuildingIn the right circumstances monolithic earth walls are an effective construction sys-tem, providing durable walls that mediate the daily and seasonal temperature swings. Earth construction may well be the oldest method of building in the world, as ancient cities of Mesopotamia were built of rammed earth and stone. It is the quintessential local building material, with a large variety of types and styles suited to an equally large variety of climates and soil types.

Some of these systems include adobe, light straw-clay, cob, and hybrid adobe. Rammed earth or the sprayed soil-cement variation known as PISE. Soil-cement is typically reinforced, and stabilized with cement or lime, important when working in locations with seismic concerns.

Without an insulating layer, monolithic earth construction should only be used in relatively mild climates and with careful attention to solar orientation, shading and passive design. The mass helps mediate diurnal temperature swings, but spaces may become too warm or cool during unseasonable periods of weather. We generally pre-fer to use earth as a finish on straw-bale or other insulating systems, or as a thermal mass wall within an insulating envelope. This way the full benefits of the earthen walls are enjoyed in a wider variety of climatic conditions.

Aesthetically a variety of textures and finishes can be achieved depending on tech-nique – from the striations of a rammed earth wall, to a textured or troweled sprayed wall – giving structures a natural, timeless quality.

Adobe

Adobe is the popular Spanish word for mud brick. The term Adobe refers to an un-fired earth brick used for building walls. Adobe bricks are made of sand, clay, water, and sometimes straw.

The brick typically measures approximately 10”wx14”lx4”h. The bricks are dried in the sun and then stacked to build walls. Often covered in stucco or earth plaster, adobe walls provide excellent thermal mass that combines well with passive solar heating. Adobes can also be used to form vaults and domes. Adobe is a forgiving material.

Some feel that the unfired clay in adobes has an additional low- tech evaporative cooling effect similar to a phase change material.Sometimes adobes are stabilized with various additives to make them more impervi-ous to moisture. Most of the oldest structures still in existence are were constructed with adobes. An adobe is a very natural product. Some estimates suggest over 1/2 the worlds population live in earthen structures.

Compressed Earth Block

Often called CEB’s or pressed adobes, are construction blocks composed of clay, sand, and sometimes a stabilizing ingredient (such as lime or Portland cement). These blocks are uniform in size and shape due to the fact that the ingrediants are pressed by a hydraulic or lever arm machine. These CEB machines can be transported to remote regions to transform unfertile dirt into long term housing (emergency) quickly.

Compressed Earth Blocks can be entirely natural. As with sundried adobes, com-pressed adobes add excellent thermal mass that helps alleviate indoor temperature fluctuations. CEBs are denser than sun dried adobes.

Rammed Earth

Is a wall system made of earth, water, and sometimes cement tamped in lifts inside of removable forms.

Compaction is the force which turns soil into sedimentary rock. In rammed earth, compaction occurs through impact, the force of a tamper falling time and again on a recipient soil mass. This impact not only compresses the soil, but also encourages the individual particles within the soil to realign themselves. The jarring action of the tamper forces the particles into the tightest possible molecular and mechanical configuration.

Rammed earth construction can utilize local natural materials and provides excellent thermal mass.


Passive SolarPassive Solar Design takes advantage of site, climate, and the energy of the sun to provide thermal comfort - both heating and cooling. Shaping and orienting buildings and paying careful attention to design, building systems and detailing are key to opti-mizing the passive performance. Because the strategies are so variable depending on the specifics of the location, passive solar design results in buildings that are finely tuned to their settings and site.

In most climates buildings can achieve passive comfort for a majority of the time, with additional energy inputs for extreme periods of weather being met through supplemental systems, ideally from renewable energy resources (aka ‘active solar’), as discussed below.

Factors that influence the siting of a structure include orientation relative to solar ac-cess, protection from harsh sun or winds, and relationships to slopes or existing vege-tation. Generally buildings should have the majority of their glazing facing within 30° of due south, and we find that in most instances the optimal orientation is roughly 17.5° east of due south, so a building has more morning gain and less later in the day. Microclimate conditions (i.e. fog, diurnal temperatures, etc.) and the specifics of the site require further consideration when determining the optimal orientation.

Passively heated buildings typically feature high insulation levels and tight con-struction, south-facing glazing, and thermal mass within the building’s insulation envelope. Thermal mass is defined as heavy, dense materials, which might include slab-on-grade floors, thick soil or plaster wall finishes, thick or double gypsum board finishes, and masonry elements such as fireplaces, masonry heaters, or planters. Properly sized shading over windows and doors is key to controlling unwanted solar gain. Generally one wants to limit east, west and north facing glazing, though with high quality windows and advanced glazing systems one can enjoy views in these directions without high energy loss or gain penalties.Passive cooling similarly features proper shading and thermal mass within the build-ing envelope, and in many climates a comfortable environment can be maintained with natural ventilation alone. Here in California where nighttime temperatures are lower, night flushing via fans or natural convection (warm air rising) can be used to remove heat stored in the thermal mass from the building. Windows or fan openings are then closed in the morning and the mass helps keep the building cool and com-fortable.

Other passive design features that can reduce the active energy needs of a building include daylighting, air-to-air heat exchange, radiant barriers and/or ventilated roof systems, and movable shading systems such as shutters or awnings. Employing these passive strategies can reduce or eliminate the mechanical systems, saving both direct costs and long-term energy costs.

By properly orienting the building & windows, adding thermal mass, analyzing sun angles to determine overhang sizes and locations, and adding night insulation, the use of solar energy can greatly decrease the need for mechanical heating and cooling systems, thus greatly reducing energy costs. By balancing room volume, south facing glass, and thermal mass, the sun’s energy benefits are maximized without the use of mechanics, machines, or electronics.

There are three main methods to utilize passive solar heating. They are: direct gain, trombe wall, or green house strategies that can be mixed depending on circumstanc-es. Depending on the climate, or site conditions it may be necessary to combine passive solar with backup systems in order to achieve effective and flexible heating and cooling.


Active SolarActive Solar describes energy systems which capture the sun’s energy and store it in some manner for later use, through mechanical or electrical means. The two basic types are electrical systems, such as photovoltaics, wind, or hydro, and thermal sys-tems that heat liquid for domestic hot water and/or space heating needs.

Active solar systems use mechanical components such as solar hot fluid pipes, pho-tovoltaic solar panels and wind generators for collection of active solar energy. These technologies can absorb the sun’s heat and store it in water tanks, rock beds, or the like. Pipes or wires and ducts are required to distribute the heat with the aid of fans and pumps. A renewable energy, active solar is a sustainable way to heat fluids or create electricity.

Renewable Elec. SystemsResidential scale renewable energy typically means electricity generation via photo-voltaic panels, but if the conditions allow, wind or micro-hydro are attractive renew-able energy options. The discussion here is focused on photovoltaic (aka PV) systems.

Framed PV panels are the most common form of photovoltaic energy collection. These panels laminate solar cells (thin slices of mono-crystalline or polycrystalline silicone) onto glass surfaces which are interconnected in arrays generating DC (direct current) electrical energy, typically between 12 and 48 volts, though some grid-in-tertie inverters operate at higher voltages. An inverter converts the DC current into typical household AC (alternating current) 120 volt power.

Regarding residential projects, the average California household uses 20 kWh (kilo-Watt-hours) of electricity per day. With some basic energy conservation (efficient lighting and appliances, limited or no air conditioning, and conscious use) a house-hold should be able to get that use down to 10 kWh or less. Assuming an average of 5 hours of sunlight, and some electrical inefficiencies (line loss, inverter, etc.) this would require an array of approximately 2500 Watts (2.5 kW).

Typical PV panels generate 10 Watts per square foot, so a 2.5 kW array will cover an area of roughly 250 sq. ft. For top performance panels are sloped and oriented close to due south. Optimal orientation and slope depend on ones latitude and weather patterns; here in the San Francisco Bay Area the optimal angle for a fixed array facing due south is approximately 30° above horizontal. With seasonally adjusted panels, one can achieve an additional 10% of production. Fully tracking arrays can increase output by about 35% at our latitude, but tracking systems are prone to significant maintenance.


Solar Thermal SystemsCollecting heat from the sun and storing it in the form of water is the most typical active thermal system, with the heat then being used later for domestic hot water and/or space heating needs. There are a few basic variations we employ, but we aren’t limited to these.

Batch collectors use domestic water pressure to push fresh water through the hot water collector, for domestic needs. This type of collector can only be used in cli-mates that do not experience hard freezes. When the tap is turned on, heated water is pushed from the panel to the faucet where it is replaced with cool, incoming water. Often this is piped through a hot water heater, either as a pre-heat to a tank type heater, or through a solar-calibrated instant hot water heater, which doesn’t turn on if the water is already hot.

Solar hot water systems in freezing climates will typically feature a closed loop system running anti-freeze (glycol) treated water through the collectors to a heat ex-changer which in turn heats water in a solar storage tank. Unless the tank is located above the panel, this water must be pumped mechanically, either with a thermostat-ically controlled pump, or a 12V DC pump powered by a photovoltaic panel, which is elegant system in that it only runs when the sun is shining, heating the water in the collector.

Space heating can be accomplished with a variation on the closed loop option, by in-creasing the size of the collector array and, following the heat exchange, piping some of the heated fluid to either a large hot water storage tank, or through tubing that is buried in a 2’ to 3’ deep insulated bed of sand beneath the floor slabs. This combined solar direct hot water and space heating system was pioneered by Shelter Systems in Wisconsin, and made popular by Bob Ramlow. (This system and all things related are discussed in Bob’s book ‘Solar Water Heating’). This system can be combined with masonry heaters and wood-burning boilers as well as with air-source and geo-ex-change heat pumps.

Solar Hot Water

1. Solar water heating systems use solar panels, called collectors, installed on the roof.

2. These collect heat from the sun and use it to warm water which is stored in a tank.

3. A boiler or immersion heater can then heat the water further until it reaches the temperature set by the tank’s thermostat.


Reclaimed, Recycled & Local Reclaimed materials are re-used without any reprocessing. Direct re-use of materials, products, or goods that may involve cleaning or refurbishing.

Adaptive Reused MaterialsMaterials re-used for an entirely different function.

Recycled MaterialsMaterials that would have been considered waste, but was reprocessed to make a new consumer product. With energy input, the re-use of post consumer or post industrial waste.

The re-use of materials is not only environmentally correct, but recycled materials can also be as interesting as natural materials. There is a crucial need for our econo-my to duplicate natures cycles, in which the waste of one process becomes the food for another.

Light-Weight ConcreteA concrete building system that utilizes a light-weight aggregate or has a substantial amount of air in the mixture. Some light-weight aggregates are pumice (volcanic rock) or fly ash. Some fly ash is reclaimed from industrial waste.

Lightweight concrete typically has a medium compressive strength, and fairly good thermal mass and insulation qualities. This medium weight material is easy to work with and has proven to be a very efficient building system.

These materials can be environmentally sound, plentiful, energy-efficient, safe, reli-able, and as easy to use as traditional materials (such as wood or standard concrete).


SIPsSIPs are the 21st Century Building Material

Structural insulated panels (SIPs) are a high performance building system for residen-tial and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB). SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design. The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labor.

Building with SIPs generally costs about the same as building with wood frame construction when you factor in the labor savings resulting from shorter construction time and less jobsite waste. Other savings are realized because smaller heating and cooling systems are required with SIP construction. Structural insulated panels (SIPs) are one of the most airtight and well insulated building systems available, making them an inherently green product. An airtight SIP building will use less energy to heat and cool, allow for better control over indoor environmental conditions, and reduce construction waste.

WATER STRATEGIESReduce site disturbance, restore open space by using indigenous plants and develop-ing a more natural landscape solution will help to achieve this credit without adding any cost to the project. Choosing plants that need little water and no irrigation sys-tem will reduce the operational costs associated with an irrigation system. (SS Credit 5.1)

Limit disruption of natural water hydrology by reducing impervious cover, increasing on-site infiltration, reducing or eliminating pollution from stormwater runoff, and eliminating contaminants. Design the project site to maintain natural stormwater flows by promoting infiltration. Specify vegetated roofs, pervious paving, and other measures to minimize impervious surfaces. Reuse stormwater volumes generated for non-potable uses such as landscape irrigation, toilet and urinal flushing and custodial uses. (SS Credit 6.1)

Limit disruption and pollution of natural water flows by managing stormwater runoff. Use alternative surfaces (e.g., vegetated roofs, pervious pavement or grid pavers) and nonstructural techniques (e.g., rain gardens, vegetated swales, disconnection of imperviousness, rainwater recycling) to reduce imperviousness and promote infiltra-tion thereby reducing pollutant loadings. Use sustainable design strategies (e.g., Low Impact Development, Environmentally Sensitive Design) to design integrated natural and mechanical treatment systems such as constructed wetlands, vegetated filters, and open channels to treat stormwater runoff. (SS Credit 6.2)

No potable water use for landscape irrigation. Perform a soil/climate analysis to de-termine appropriate plant material and design the landscape with native or adapted plants to reduce or eliminate irrigation requirements. Where irrigation is required, use high-efficiency equipment and/or climate-based controllers. (WE Credit 1.2)

Innovative wastewater technologies and water use reduction. Use high-efficiency fixtures, dry fixtures such as composting toilets and waterless urinals, and occupant sensors to reduce the potable water demand. Reuse of stormwater and greywater for non-potable applications such as toilet and urinal flushing, mechanical systems and custodial uses. (WE Credits 2 & 3)

Toward Net-Zero Water

The key here is to emphasize closed-loop systems, ultra-efficient measures to reduce system demands, small-scale management systems, fit-for-purpose water use and diverse, locally appropriate infrastructure.

Establishing a water balance (a numerical account of how much water enters and leaves the boundaries of a project) is a critical step in understanding water flows on-site. Balancing available on-site water supplies, including rainwater and recycled water, with occupant demand. Net-Zero Water Abstract (Cascadia GBC)

Tucson Mountain RetreatArchitects: DUSTLocation: Tucson, ArizonaArea: 3,640 sqftYear: 2012

The Tucson Mountain Retreat is located within the Sonoran Desert; an extremely lush, exposed, arid expanse of land that emits a sense of stillness and permanency, and holds mysteries of magical proportions. The home is carefully sited in response to the adjacent arroyos, rock out-croppings, ancient cacti, animal migration paths, air movement, sun exposure and views. Great effort was invested to minimize the physical impact of the home in such a fragile environment, while at the same time attempting to create a place that would serve as a backdrop to life and strengthen the sacred connections to the awe-inspiring mystical landscape.

Intentionally isolating the parking over 400 feet from the house, one must traverse and engage the desert by walking along a narrow foot-path toward the house, passing through a dense clustered area of cacti and Palo Verde that obscure direct views of the home Upon each progressive footstep, the house slowly reveals itself, rising out of the ground. The entry sequence, a series of playfully engaging concrete steps, dissolves into the desert. As one ascends, each step offers an alternative decision and a new adventure. Through this process, move-ment slows and senses are stimulated, leaving the rush of city life behind. The home is primarily made of Rammed Earth, a material that uses widely available soil, provides desirable thermal mass and has virtually no adverse environmental side effects. Historically vernacu-lar to arid regions, it fits well within the Sonoran Desert, while at the same time it embodies inherent poetic qualities that engage the visual, tactile and auditory senses of all who experience it.

The program of the home is divided into three distinct and isolated zones; living, sleeping, and music recording/home entertainment. Each

zone must be accessed by leaving the occupied zone, stepping outside, and entering a different space. This separation resolves the clients’ desired acoustic separation while at the same time, offers a unique opportunity to continuously experience the raw desert landscape.Rooted in the desert, where water is always scarce, the design incor-porates a generous 30,000 gallon rainwater harvesting system with an advanced filtration system that makes our most precious resource available for all household uses.

Solar heat gain is reduced by orienting the house in a linear fashion along an east–west axis, and by minimizing door and window openings in the narrow east and west facades. The main living and the sleeping spaces extend into patios and open toward the south under deep over-hangs that allow unadulterated views and access to the Sonoran Des-ert. The overhangs provide shelter from the summer sun while allowing winter sunlight to enter and passively heat the floors and walls. They also scoop prevailing southerly breezes and enhance cross ventilation, which can be flexibly controlled by adjusting the floor-to-ceiling sliding glass doors. When the large glass doors are fully opened, the house is transformed, evoking a boundless ramada-like spirit where the desert and home become one.

Rondolino ResidenceArchitect: nottoscale Location: High Desert near Scotty’s Junction, NevadaSize: 1,200 sf building, 900 sf exterior deckCompleted: December 2010

The Rondolino residence is the prototype of the T-modulome, a prefabricated build-ing system by nottoscale that was first developed in 2002.Fabrizio Rondolino, an independent writer and author from Rome, Italy commis-sioned nottoscale to build the T-modulome on an isolated stretch of land in the Nevada desert near Scotty’s Junction. After a couple of challenges that we faced due to the remoteness of the site and the Wild West mentality of the local contractors, the building was finally completed in December of 2010. During the entire process the client and architect solely communicated via e-mail and did not even meet or talk once – and to this day have not met in person.

The site is an isolated piece of land in the Nevada High Desert near Scotty’s Junction and is far from any infrastructure or for that matter any neighbor, which is why we had to scrape a dirt path to the site, dig a well, create a leech filed and bring electrici-ty to the site. After spending several days on the site, nottoscale situated the building in such a way as to take full advantage of the surrounding views, existing wind pat-terns and the trajectory of the sun.

The client loves the desert and wanted a vacation home in the middle of this isolat-ed stretch of high desert that incorporates the vistas by visually expanding into the surrounding landscape, providing stunning views, while also making the desert part of the interiors – merging the inside with the outside.

One of the main design considerations was to take advantage of the views and to give the owner the feeling to be in the middle of the desert even though when he is inside the home. This is why we introduced large floor to ceiling windows in all living quarters and raised the building on a concrete plinth which seems to emerge out of the desert landscape while overlooking the scenery. This gives the user the impres-sion to float over, yet to be completely immersed into the desert landscape. We also took great care how to place windows so that they frame special aspects of the landscape – the long and low window in the kitchen for example frames a beautiful mountain range which one can only see while sitting down at the dining table.

The house itself measures 1,200 sf, has 3 bedrooms, two bathrooms, an office, a storage and utility room as well as a large open kitchen, dining room, living room area that can extend onto the deck when the large sliding doors are opened. In order to minimize the built envelope the enclosed rooms are kept relatively small while a 9’-0” ceiling together with floor to ceiling windows make the space seem spacious

and flooded with light, while visually expanding and connecting the interiors with the desert landscape.A large 900 sf deck with a sunken-in hot tub connects the two building modules while creating a transition zone between the inside and outside that through the use of large full height glass sliding doors can be completely opened so that the outside and inside of the building seamlessly merge if one desires so.

The building itself sits on a large concrete plinth elevating the building above the desert floor so that it appears to float above the ground while lifting it out of the flash-flood water level. Passive cooling concepts such as cross and stack ventilation, shading, building orientation were used throughout the project.

The House is oriented in such a way as to take advantage of prevailing winds that, through cross and stack ventilation, maintain a comfortable temperature in the house, avoiding the need for an highly energy intensive air conditioning system. The windows facing south are shaded by the large trellis on the deck while all the bed-room windows are facing north in order to prevent heat-gain. The large crawlspace under the house double functions as storage space as well as a climate buffer as it is filled with gravel that helps to maintain a low average temperature below the house throughout the year.

The house is built with high insulating SIP panels and is heated with a radiant heating system that can easily be upgraded to a radiant cooling system if the client desires to do so. Various sustainable systems and approaches were used in order to minimize the physical as well as the carbon footprint of the building.

The architect did not only furnish the entire house but also provided all items that are needed for a stay such as a fully equipped kitchen, stereo system, washing machine, alarm system and tools, so that the client only needs to bring his clothing and food when he comes to the house. Making this a truly turn key vacation home.

J2 ResidenceArchitects: assemblageSTUDIOLocation: Las Vegas, Nevada, USAArea: 12,000 sqftYear: 2011

The project is located in the master planned development of Summerlin, along the western edge of Las Vegas at the base of Red Rock. The community’s design require-ments call for “design individuality, horizontally and sensitivity to the desert hillside environment.” J2 recognizes the owners and developers combined appreciation of the desert environment through our choice of materials, environmental orientations, daylighting, landscaping and use of renewable energy sources.

Our client desired a home that engaged the outdoors within their living spaces. Expanded views into the adjacent golf course and foothills provide a connection be-tween indoors and out. Each public space; great room, dining room, library, and casita is provided a view into the distant landscape as well as intimacy with the courtyard and pool. The basement bar and game room area connects to the outside through a courtyard which admits daylight into the space.

The home provides a large percent of its own power consumption through Kyocera Multicrystal Photovoltaic Modules placed on the wing canopy.

The canopy has been designed to eliminate direct sunlight from entering into the residence during the hottest seasons while allowing maximum visibility to the south. Rammed earth construction creates a thermal mass to mitigate the extreme fluctuations in day and nighttime temperatures.

Haus SimmaArchitects: Georg Bechter Architektur+DesignLocation: Egg, AustriaArea: Floor area: 169 m² (1,819 sf)Year: Reconstruction completed in 2010

In Bregenz Forest in Austria, a brick building from the 1960s was turned into a resi-dential house optimized in terms of energy costs and ecological features.

Future-oriented Building from the 1960s The house of the Simmas in Egg in Bregenz Forest in Austria was not able to meet the family’s requirements. The layout from the 60s was not outdated, but the main prob-lem was that the house did not meet current standards in terms of energy standards. The family assigned Georg Bechter Achitektur + Design to take care of overhauling and renovating the building. As much of the existing structure was to be kept, how-ever, living comfort were supposed to be adapted to today’s standards. With House Simma Georg Bechter showed how these two aspects were able to be connected with each other and which potential buildings from the 60s can have.

Turned and opened In a way, the house was a “troublemaker”, since it was the only building the gable of which was built crosswise to the roofs of the neighboring buildings. Within the scope of the overhaul works the roof has been raised half a level and turned at the same time, so that its gable now points into the same direction as the ones of its neigh-bors.The layout of the inside has been altered as well. The rooms on the first floor have been opened and connected with each other, so the architect was able to create a spatial continuum. The ceiling of the living area has been raised by 80 cm. This has created a bright, generous room. The kitchen ceiling, lower by default, has been left the way it was. The various room heights give the rooms, despite the open layout, a character of its own. On the upper floor you will find three bedrooms and a bath-room.Consequently ecological and regional

During the renovation project the architect and the customer had the main focus on ecological aspects. In order to improve insulating properties, the whole brick building has been enwrapped into a 40 cm thick straw layer. Apart from that, uneven parts were straightened and overhanging roof edges were cut off. The result was a com-pact structure which was able to be brought to low-energy standards thanks to the insulation. On the first floor the inside walls were faced with 3 cm thick panels, on the upper floor loam rendering was deployed. Both materials can pick up and absorb moistness and thus guarantee, together with the integrated heat recovery ventilation system, a well-balanced room climate. After this the walls are now nearly 81 cm thick.

House Simma is now a consequently ecological residential house, which also convinc-es through its regionally oriented overhaul. All materials, be it wood or straw, come from the nearby surroundings and have been deployed completely untreated. Also the involved companies are located nearby, the architect lives only 6 kilometers from the house. The customers also gave a helping hand during the project.

Massive Structure with a regional “Dress” The unusually thick walls are not only of energetic benefit, the compact character of the structure also serves as a means of design. The window reveals are getting thinner towards the top and thus emphasize the walls’ thickness towards the outside. The reveals also let plenty of natural light inside. The smoothed wooden facings are a visual contrast to the timber shingles, encasing the house from all side, which is typical for the region. The massive building has been embedded exceptionally well into the built surroundings thanks to the shingle façade.With house Simma, Georg Bechter did a great job in blending old and new. This should not only be a new standard concerning the renovation of old buildings. His project serves – from an ecological as well as from a design-oriented point of view – as a role model for sustainable and regional (re-) buildings.

BaleHaus@BathAs part of ModCell’s® ongoing research programme we have built a two storey BaleHaus® on the campus of the University of Bath. The project is known as the BaleHaus@Bath.

The construction programme commenced on the 16th of June 2009 and was com-pleted in September 2009.

The research will concentrate on a number of key area’s including:• Thermal performance• Acoustics• Air tightness• Relative Humidity

The building has been fitted with the latest testing technologies to monitor all as-pects of the buildings performance.At the end of the project the building will be dismantled and relocated to another site.

The ModCell® panels being used on the first floor of the building were previously used as the ground floor of ‘The House That Kevin Built’, THTKB. We are delighted that they have found a new home at the University of Bath.

‘The unique combination of high energy efficiency, use of renewable materials, and the ability to capture and store carbon in the structure, that Balehaus® offers are a very exciting prospect for the market. That’s why the Technology Strategy Board has supported the development of both Modcell® and Balehaus® as products with significant potential to reduce the environmental footprint of buildings’.

“We won’t get to an ultra-low-carbon built environment simply by improving on the performance of the same old construction techniques. We need a lot more genuinely disruptive innovation. The BaleHaus (incorporating specially designed straw or hemp bales) certainly hits that button, and could play an important part in enabling house builders (both big and small) to meet their carbon targets, stay profitable and provide people with the quality, style and comfort they’re looking for.”Jonathon PorrittFounder DirectorForum for the Future

modcell overview

ModCell® is one of the first products to make large-scale, carbon-negative building

a commercial reality. The ModCell® system utilizes the excellent thermal insulation qualities of straw bale and hemp construction to form prefabricated panels, made in a local Flying Factory™. ModCell® allows super-insulated, high-performance, low energy ‘passive’ buildings to be built using renewable, locally sourced, carbon sequestering that offers sustain-able building materials.ModCell® is designed for use in offices, schools, housing and commercial buildings.

This innovative, offsite-manufactured wall and roof cladding system can be quickly and efficiently installed, creating buildings with thermal performance up to three times higher than the current building regulations require.

This super-insulated system, combined with our airtight details, means that buildings constructed using ModCell® panels meet the demanding PassivHaus specification. As a result, ModCell® buildings can have zero heat requirements, saving money and CO2 emissions.

Millette/Burch CabinNevada City, California

This 872 s.f. off-grid straw-bale project is a getaway home for a San Francisco couple with two active young boys.

Located at 3600 ft. elevation in the remote Nevada County, the house mediates the northern edge of a forest glade, with driveway access and entry against a steeper slope to the north. The entry/mudroom, bath and mechanical space are located in a wood-framed volume a half level up from the main living space. This simple, straw-bale volume opens to a south-facing terrace, connecting it to the forest glade, and a more intimate queen bed sized sleeping bay. An open loft above the kitchen provides additional sleeping space for kids and guests.The house features energy independence by necessity. Solar hot water collectors provide domestic hot water as well as space heating by flowing the heated fluid first through a heat exchanger and then into tubing buried in a 2 ft. bed of sand beneath the floor slabs. P.V. panels on the roof harvest electricity, stored in batteries, power-ing the well pump and other domestic needs.The metal roof, earth-cement on bale walls, fiber-cement siding and fire safe perime-ter aim to survive a wildfire, ensuring that this small cabin will provide many years of service.

David Arkin and Anni Tilt of Arkin Tilt Architects design beautiful homes. A lot of ar-chitects design beautiful homes, though. What distinguishes the work of Arkin Tilt is their ability to capture the essence of a place and the personality of a client and craft a design that complements both to near perfection.What makes the firm particularly unique is their unwavering dedication to ecolog-ically sensitive design. They won’t take on a project that doesn’t have energy and resource efficiency as a core focus. This takes us to the Chalk Bluff Cabin, an off-the-grid straw bale getaway high on the remote edge of the Tahoe National Forest in California.Hybrid Straw BaleThe 872 sq.ft. cabin is a hybrid straw-bale home. That simply means that some of the walls are conventionally built with dimensional lumber, the roof is made of SIPS and the other part-the main volume in this case-is built with straw bales. It’s an approach commonly taken by the firm, who are strong advocates of the ecological and perfor-mance benefits of building with straw bales, but acknowledge the benefits of other construction methods as well.Cut off from the GridThe home is so remote that its location is well beyond the utility grid. The home harvests energy from the sun through a PV array on the roof and stores the energy in batteries to operate the well pump and other domestic electrical services. A Solar

Hot water collector provides domestic hot water and heat for the small cabin. Along with the solar hot water collectors heating is accomplished through a 2ft deep Sand-bed heat storage system.Though it’s tucked deep into the wilderness, the home sits isolated in a clearing to protect it from wildfires. The siding, metal roof and earth-cement on bale walls all contribute to the home’s wildfire resistance.An Honest Interior Inside, the home is unadorned with plywood-clad ceilings, polished concrete floors and rich, textured plastered walls. The arrangement of the floor plan is simple, but executed with defined, functional spaces. A queen sized sleeping nook off the living room, for instance, can be used as daytime away space while still being connected to the hub of the house. At night, it becomes its own bedroom by being buffered from the other sleeping areas by the living room. The kitchen, tucked below a bedroom feels as though it occupies its own room even though it shares floor space with the main living area.Upon visiting their site, Arkin Tilt presents you with a short passage. It reads:“As a branch grows in search of sunlight so too does a design evolve as a natural fit to its climate and circumstance.”Like all of their work, the Chalk Bluff Cabin delivers on that idea.Residential Architect, “Mountain Solo”, July 2011

The Green House: new directions in sustainable architecture

case study homes 71

Jackrabbit WashArchitects: Aaron D’Innocenzo Location: Joshua Tree, CaliforniaArea: 148 sqm (1,600 sf)Year: 2012

This house was designed and hand built entirely by the owner as his first major proj-ect after graduating with a Master in Architecture. It is located in the Mojave Desert near Joshua Tree, California.As a result of its passive solar design, the house is able to heat and cool itself year-round, with no external energy input from traditional HVAC systems.

In many ways, this house is the antithesis of Le Corbusier’s concept of a house as a “machine for living in”, as it is highly site-specific, extremely energy efficient, does not rely upon HVAC systems for temperature control, and nearly every element was designed and hand crafted specifically for this house.

The project took nearly eight years to complete as all of the construction was done by the owner/architect himself. No contractors, sub-contractors, or daily helpers were involved.

Pueblo Revival StylePueblo Revival homes borrow ideas from the ancient earthen homes of Native Amer-icans.

Pueblo homes have many of these features:

• Massive, round-edged walls made with adobe• Flat roof with no overhang • Stepped levels • Rounded parapet • Spouts in the parapet to direct rainwater • Vigas (heavy timbers) extending through walls to support the roof • Latillas (poles) placed above vigas in angled pattern • Deep window and door openings • Simple windows • Beehive corner fireplace • Bancos (benches) that protrude from walls • Nichos (niches) carved out of wall for display of religious icons • Brick, wood, or flagstone floors

Due to Spanish influence, Pueblo Revival homes may also have these features:• Porches held up with zapatas (posts) • Enclosed patios • Heavy wooden doors • Elaborate corbels

Variations of the Pueblo Revival style: • Pueblo Deco. Combining Pueblo Revival with Art Deco architecture, these homes are decorated with geometric patterns and Native American designs. • Santa Fe Style. This type of Pueblo became the standard in New Mexico after it was defined by the Santa Fe Historic Zoning Ordinance of 1957. • Contemporary Pueblo. Stripped down, unornamented Pueblos without posts, beams, or vigas. • Territorial Pueblo. Corners are square instead of rounded. Windows are framed with straight wooden moldings.

About Pueblo Houses:

Since ancient times, Pueblo Indians built large, multi-family houses, which the Span-ish called pueblos (villages). In the 17th and 18th centuries, the Spanish made their own Pueblo homes, but they adapted the style. They formed the adobe into sun-dried building blocks. After stacking the blocks, the Spaniards covered them with protec-

tive layers of mud.

Pueblo Revival houses became popular in the early 1900s, mainly in California and the southwestern United States. During the 1920s, aviation pioneer Glenn Curtiss and his partner James Bright introduced their own version of Pueblo Revival architec-ture to Florida. In the region that is now Miami Springs, Curtiss and Bright built an entire development of thick-walled buildings made of wood frame or concrete block.

Modern day Pueblo homes are often made with concrete blocks or other materials covered with adobe, stucco, plaster, or mortar.
