Media concept How to improve health and eliminate utility bills?
Most of the population in Belarus, Russia and other countries is very cautious about the use of chemicals in food and drink - preservatives, emulsifiers, dyes, antioxidants, other food additives, although they buy food, as a rule, without reading its composition on the packaging. People are very active in protesting against the use of chemicals in agriculture - herbicides, pesticides and even fertilizers. Everyone is unanimously in favor of environmentally friendly products, constantly talking about it, but almost no one really knows what it really is and how to distinguish it from contaminated one. People are already accustomed to the massive introduction of artificial, i.e. chemically obtained, substances into the category of things and do not protest, apparently relying on the fact that they will be able to make the right choice themselves. Therefore, a significantly smaller number of people control the quality of their "second skin" - clothes, shoes, accessories and other wearable things, meticulously figuring out the proportion of synthetics in them and trying to choose items with a predominance of natural components.
It may seem incredible, but the very people who seek not to use "synthetics" in their everyday life do not think that their home is largely the same "synthetics", that is, a product of the chemical revolution.
If, when buying a suit or shoes, we try to choose those models in which generally any "synthetics" are smaller, without going into the differences between the types of synthetic substances, then, when building or renovating our home, most often we do not even ask about the composition and the origin of certain building materials.
Choosing a suit according to the criterion of the naturalness of the fabric, we usually do not think about the naturalness of the lining, not to mention the material of the threads, buttons and other things. In the case of housing, such a lightweight approach is unacceptable, if only because there are much more massifs and surfaces of building elements, which means that the flow of influences on a person is many times more powerful.
Those who ask such questions usually reassure themselves that everything will be in order if the main building material of the house is brick or wood, which are not suspicious due to their centuries-old testing. But they forget that 60–70 years ago a log thinner than 40 cm in diameter was not used in housing construction due to high heat losses (and now finding such a log is a problem) and that in such a complex system as a house, there are other materials, the effect of which cannot be compensated for by brick or timber walls.
To an even lesser extent, designers and builders care about the environmental friendliness of the building materials. The reason is clear - not for myself. Even nowadays, when there is an opportunity to choose and buy materials of different levels of environmental friendliness, one has to repeatedly observe the picture of the construction of an "elite" house, during which the walls are faced with bricks on the outside, and thermal insulation made of phenolic-rezole foam or another harmful polymer is laid inside.
Natural alternative
Have you seen swallows or wasps near the nest? They are perfectly adapted to the environment, weather conditions, life rhythm and natural cycle of dwellings, which are in close connection with Nature and Space. Is it possible to use some of the techniques for constructing bird and wasp dwellings in human dwellings?
Building a straw bale house can seem like a crazy idea at first glance. But it is well known that straw bales combine all the properties of an excellent building material: they are cheap, durable, readily available, environmentally friendly and have good thermal insulation. Straw bales are durable as long as they are protected from penetrating and increasing moisture. Their insulating properties are much better than those of wood or brick. A straw block with a typical thickness of 50 cm has excellent thermal insulation properties, which are improved after plastering. Moreover, the wall remains "breathing" an order of magnitude higher than a wall made of natural logs. Thick walls with their textured surfaces have particular advantages. "Living" and "breathing" structures create an extraordinary indoor climate, allow you to feel confidence and security. Rigid rectangular surfaces and smooth walls from straw blocks can also be created, but it takes more skill and effort. They are not characteristic of this natural material. Houses made of straw cubes, on the contrary, will delight the eye, delight with soft lines. Thanks to the easy handling of straw blocks, round shapes are also possible. Niches or round arched windows and doors are made using an ordinary electric saw, cutting out the desired shape in the straw. Although if the owner gravitates towards flat planes and right angles, there are no problems either ...
Warm nest made of straw
The eco-house project is based on the principle of compliance with the theory of sustainable development - development, in which meeting the needs of the modern generation does not jeopardize the ability to meet the needs of future generations. The ecological imperative is included in the concept of the project as a component of the dominant.
The project, in addition to the general requirements for the construction of the building, was drawn up on the basis of the following provisions:
Planning and volumetric solutions should take into account the peculiarities of the landscape and construction technologies and ensure the maximum ecological quality of the living environment - internal and external - at minimum costs;
The house and the plot make up a single artificial ecosystem that does not harm the environment and the health of the present and future generations;
The total energy consumption (especially the energy of fossil fuels) both during construction and during the operation of buildings should be minimal;
Maximum use of environmentally friendly materials, respect for local flora and fauna;
Socialization of the habitat.
The planning of the territory was carried out taking into account the use of the principles of passive "solar" architecture and was aimed at socializing the territory, developing a human-friendly environment, which should become a "small homeland" for the current and future generations of eco-house residents.
This dictated the planning decisions for the development of the territory and the "sunny" architecture of the buildings: a thatched house can be provided with a small pool and a sauna (at the request of residents), a fireplace. The eco-house can be equipped with local low-cost permaculture systems for utilization of household waste water, which improve the fertility of household plots and worked out in the climatic conditions of Belarus.
A straw eco-house is usually made energy passive: the enclosing structures have a coefficient of resistance to heat transfer of at least 8 (modern SNiPs require 2.5), only local environmentally friendly natural materials are used (straw blocks are supplied directly from the field during the harvesting of cereals), which has a good effect on cost indicators. During the construction of the eco-house, earth-moving and lifting mechanisms are not used, since the walls are light and do not require a large amount of reinforced concrete in the foundation, which allows you to preserve the grass cover and not injure the earth, which our ancestors considered (and not without reason) to be "alive".
The eco-house was built using the eco-technology of erection of enclosing structures, already well-proven in Belarus (plastered or covered with plasterboard, a wall made of straw blocks) in a frame version (the load is carried by a wooden timber frame).
This technology provides the following parameters:
Energy indicators. Energy consumption during construction is reduced by at least 300 times in comparison with brick and gas silicate enclosing structures with modern insulation per 1 m2 of the total area.
Coefficients of thermal conductivity of enclosing structures. The thermal conductivity of the unheated floor is 0.23 W / m2K, the thatched wall is 0.12 W / m2K, the roof is 0.19 W / m2K.
Energy requirement for heating.
Less than 40 kWh / m2 per year.
High fire safety (after plastering).
Confirmed by official tests. The structure of the plastered straw wall has been officially tested in the USA and Germany and is classified as fire class F119 (a metal truss, for example, is classified as F15, i.e. it loses its load-bearing capacity 15 minutes after exposure to an open fire).
Construction time. From the moment the earthworks (foundation) start to the moment of settlement, it takes about 14 weeks, if the construction is carried out rhythmically.
Construction cost. The cost for 1 m2 of the total area with a "wallpaper" finish in the basic version is about 260 USD. e. (in 2006).
Implementation experience.
In Belarus, the first rural eco-houses from straw blocks were built in 1996. In 1999, after official testing, the Ministry of Construction and Architecture of the Republic of Belarus recommended the projects of these eco-houses for reuse.
Their construction continues in increasing volumes, and, starting as the construction of "housing for the poor", turned into "housing for the middle class and smart rich". It is this part of the population that is today concerned about the ecological quality of their home (the problems of the impact on health of polystyrene, polyvinyl chloride, phenol formaldehyde, etc.) and the cost of heating, as well as the environmental problem of global climate change. It is already clear to everyone that gas prices are unlikely to fall in the future, but will only increase many times over. The requirements for WTO accession are to raise energy prices to the world (European) level. By 2011, in Russia, the domestic gas price will reach the European one (230 USD per thousand m³ in 2006) On heating 1 m3 of straw eco-houses, 3-4 times less energy is spent, which has been proven by practice ...
All the necessary regulatory and technical documentation is available. For the first time in the history of the CIS, developers were awarded the International Prize for Energy Efficiency and Sustainable Energy in the Housing category (Austria, 2000), nominated for the UN Habitat Prize and a number of other prestigious international awards. In 2003-2004. a number of foreign specialists, including German, Latvian, Lithuanian, Russian, Ukrainian, learned this ecotechnology during the seminars of the Belarusian branch of the International Academy of Ecology (BO MAE). Note: we are not with them, but they are with us.
It is known from the Bible that the wise Solomon gave values equivalent to the cost of several cities for the craftsmen who “knew how to cut wood”. Why? Esotericists know that if a person interrupts someone else's life (for example, a tree) to create objects that satisfy his immediate needs, then he bears karmic responsibility for this. Therefore, the skill of cutting wood in ancient times consisted in the ability to reduce or remove this responsibility, to preserve the purity of the energy of the tree and to increase its service life, which contributed to the formation of a favorable energy situation in the constructed dwelling. The eastern teachings of Feng Shui have preserved bits of this knowledge, but still today we practically do not know anything about it.
At best, they will tell you that the forest must be prepared in winter and at a certain phase of the moon ... Straw is another matter: the plant has gone through a full cycle of development, the energy of the stem is powerful and positive, special skills are not required during harvesting, and the energy of the home is excellent. This is emphasized by everyone who lives in eco-houses made of straw. For example, residents of the Druzhnaya eco-village call the straw houses “alive” and note that they “sleep well”. This is probably why the sites for the foundations of ancient religious and defensive structures, for example, the pyramids in Giza or the Great Wall of China, were lined with a thin layer of straw. Previously, Belarusians also used the energy of straw: when creating straw "spiders" that were attached over cradles and protected children from "evil spirits" (and practically blocked the effects of geo- and anthropathogenic zones), thatched roofs, mattresses (still considered medicinal), utensils, etc.
The first and most important thing is environmental friendliness. We use the most environmentally friendly materials with minimal industrial processing. Expression: the level of the included energy. In Russia, the term is not an entrance, in Europe this term is used much more often. What does it mean? The amount of energy that was expended at all stages of the production of building materials and the construction of a house. Starting from the stage of resource extraction, material handling, delivery and construction. If we compare a house built of bricks and a thatched house (assuming that the straw grows within a radius of 50 km), then the level of included energy in a thatched house will be 1000 times less. A thousand times less energy needs to be invested in building a straw house. This figure is surprising.
Second. The highest degree of energy efficiency. If we compare the walls in terms of energy efficiency, then in order to achieve the result from a straw wall 45 cm thick, a brick house must be 6 meters thick. If we talk about mineral wool and foam, then 45 cm of straw can be equated to 30 cm of mineral wool and foam. If we compare it with wood (solid wood, laminated veneer lumber), then the thickness will be equal to 90 cm. On the market there are 22, 24 cm and everyone says that it is very warm. There is no more than 28 cm on the market. The heat resistance of the straw wall is maximum and is equal to R = 9.
Third. Microclimate. The wall of the thatched house is vapor-permeable. There are no cracks in the wall like in a wooden house, and the air is always fresh. Straw is a fairly warm material and is also fairly well ventilated. But, this does not mean that the straw gives a draft. Straw houses are well protected both indoors and outdoors. No one will ever know what a thatched house made of the mind is made of. The exterior of the house is finished in the same way as other building materials. In the process of decorating houses, highly vapor-permeable plasters and materials are used. Airing a house from straw - diffusion (diffusion - movement of gases), air penetration at the molecular level. The average annual humidity level is 50%. In a stone house, when it is well heated, the air is always dry, and special steam generators are bought for humidification. The wall of the thatched house is a recuperator, i.e. some of the warm air is returned to the house with fresh air. There is no ventilation device, the ventilation function is in progress. Those. the air quality in the house is in perfect condition.
Fourth: Bio-positivity. It is interesting to note that the quantity and quality of sleep is significantly better than in urban apartments.
Fifth: Soundproofing of a straw wall. The material is an excellent heat insulator. If you have enough high-quality windows in your house, and your children walk outside the window and you want to tell them something, they will not hear you. Very high degree of sound insulation.
Many people, hearing about, will probably immediately remember the tale of the three piglets, in which the stupidest, lazy and not far-sighted pig decided to use straw as a building material. But when used and materials, straw can be one of the best options for building. Why? This issue is worth understanding in more detail.
Of course, building a house using only straw is simply impossible. Therefore, this is usually the name for frame houses made of straw. In this case, a wooden-metal frame is used as the main structure, and the main purpose of the straw is to provide the required level of heat and sound insulation. And I must admit that the straw copes with this task just fine.
Specialists carry out most of the work in the workshops of the company. Thanks to this, ready-made parts are brought to the construction site. Collecting them takes a minimum of time - usually it takes no more than one week to build an average house. This indicator can be called one of the best to date. Neither, nor can they boast of such a short construction time.
What are the advantages of straw houses
Many readers will surely have a question - why today more and more people who decide to get their own home choose a house made of straw and clay, and not classic wooden, brick or frame ones? This question should be answered in the most detailed way.
- Light weight. Anyone understands that pressed straw weighs several times less than ordinary wood, not to mention brick. Thanks to this, the work takes less time. It also eliminates the need, which is very expensive and time consuming to fill.
- The raw material is as available as possible and is easily renewable. A tree must take decades to grow to a size suitable for construction. Brick making is generally a complex technological chain. But the straw grows in a matter of months. And the cereal plants necessary to obtain straw grow in almost all regions of our country. This makes building straw houses a very easy and affordable option.
- The thermal conductivity of straw bales is very low - about 0.05-0.065 W / m * K.
To make it clearer, it is worth giving similar indicators for brick and wood. Different types of building bricks have a thermal conductivity of 0.56 to 0.7 W / m * K. For wood, this indicator is 0.18 to 0.23 W / m * K - depending on the species. This means that even on the coldest winter days, you can comfortably live in your thatched house, spending a minimum of money to maintain a high temperature. In the summer heat, it will be pretty cool in such a house - the outer walls will heat up in the sun, but they will not transfer heat inside the premises, which makes it possible to refuse. - Straw easily maintains an optimal indoor climate. Therefore, it is very easy and comfortable to be in one of these.
- Low cost. As mentioned above, the price of this material is many times lower than the cost of other building materials due to its availability. Replacing an expensive foundation with a simpler and cheaper one (pile, sometimes tape) allows additional savings.
- Compared to, straw ones do not need frequent replacement of artificial insulation (its service life usually ranges from 12 to 25 years), without which it is simply impossible to be in a frame house in the winter months.

And this is not a complete list of reasons why people increasingly choose straw bale houses.
Is a fire scary for such a house?
Someone may be horrified by the very possibility of building houses from such a fire hazardous material. After all, one spark is enough for the straw to flare up, and then a whole haystack can burn out in a matter of minutes.
But if we talk about a house made of pressed straw, such dangers can be forgotten forever.
To begin with, bales of straw are necessarily covered with a thick layer of clay, which prevents the fire from reaching the straw. Clay is able to withstand the effects of fire for a long time without the slightest harm to itself.
In the voids of the walls, filled with straw, there is practically no air left, which is needed to maintain combustion. Therefore, even when the clay is damaged and collapsed, the straw smolders only slightly, not supporting combustion.
Laboratory tests show that such walls can withstand open fire for up to 2 hours. So, thatched houses can be called much less fire hazardous than classic wooden ones.
What a thatched house might look like
Light weight of material and ease of installation allows building. This gives a huge scope for the imagination of designers, as well as people who decide to get their own home. All that remains for them to do is tell the specialists about their vision of the ideal home. In a matter of days they will be ready, and they will be able to choose the option that seems most suitable to them.
Thatched house with an unusual shape Building houses using straw does not impose the slightest restrictions on builders. Neither the wall thickness nor the specified length of the source material limits the designers' plans. Therefore, the house can really be anything.

Want a hexagonal house? Experts will be able to make your dream come true. Or maybe you like the unusual? Well, sign a contract with a construction company and a round straw house will be erected on your site in no time.
Thanks to Evgeny Ivanovich Shirokov, straw housing construction is being popularized in Russia more and more. A person who knows literally everything about this segment. Evgeny Ivanovich, tell us a little about yourself.
Konstantin Nikolaevich, head of Razekodom
I am Evgeny Ivanovich Shirokov, was born in Moscow, grew up in Khosta, this is the Sochi region. Studied at MVTU im. Bauman, graduated with honors back in 1981. In 1984 he defended his dissertation there. After that, he spent 25 years in Belarus, worked at the Academy of Sciences, then was vice-president of the International Academy of Ecology. For the last 12 years, until 2010, he was the head of the national center "Habitat". This center performed the functions of monitoring the state housing construction programs that were carried out in Belarus. In parallel with this, during the same period, for 5 years I was an expert of the red-green faction of the European Parliament until 2000. I was often attracted to work as an expert through the UN; I was twice a laureate of the UN Habitat Prize, in 2000 I was a laureate of the Energy global worlds prize in the Housing nomination for the development of straw housing construction in Belarus. For the last 5 years, I have returned to Khosta, where we are creating a center that has the functions of research and health. Now we are engaged in the development of technologies that can dramatically improve the environmental friendliness of the human environment. This is a wide range of issues: the impact on human bioenergy of enclosing structures, architectural forms, what shape should the house be, how to cover the tree - that is, patchwork wax is produced, we are engaged in cleaning the body, both in coarse energy and fine energy, partly we are engaged in multidimensional medicine. In general, a whole range of issues that allows a person to live a free, happy life. To do this, you need your home to be not just a place where you live, but a place that fully provides you - a place where labor is applied. Several projects have now been implemented in Krasnodar: a house and next to a mushroom farm made of straw panels 6 by 15 meters. This gives an income of about 450 thousand rubles in 35 days. Net income is about 100-150 thousand, depending on whether people are hired for you or you yourself. Such technologies, and they are quite interesting, because if you just go to the ground and dance in circles and do nothing, as the experience of many of our ecovillages shows, then a wave of reverse negativity arises, and it is impossible to look at it without tears. We also deal with synchronization issues. Why do people leave for the land to settlements, and after 3 years there are all enemies? Because nobody is syncing. What it is? When our ancestors went to the collective cultivation of the field, they sang together. They walked from the field - they also sang. We don't even sing in families now. If you sing together, synchronization is going on at a very high level, and in this case, you run out of reasons for conflicts. It's the same in family relationships. If you have any problem, the very last thing to do is to figure out who is right and who is wrong. You will be right, but you will be left alone. The most correct thing is joint creativity. If you have co-creation, you are automatically synced. You cannot sing, in extreme cases, sing "ohm" at least 3 times together, and you will have already exhausted the reason for the conflict. When I studied the American experience of successful ecovillages, there are places where I want to return. We practically do not want to go anywhere, with very, very rare exceptions, and I drove almost everything that we have. Because there is no synchronization, outwardly all people, as if on earth, dance in circles (by the way, also a good means of synchronization), but if there is no joint business, there is no joint creativity, then all this is doomed to conflicts.

The cost of a straw green building
What can you say about those people who are the customers of thatch houses? More often these are people who are looking for where is cheaper, or are they still those who are interested in quality and environmental friendliness?
K.N.
In Russian society, the opinion is that thatched houses are houses for the marginalized. But this is not the case. The most expensive hotel in the Krasnodar Territory is made of straw, and the most expensive houses in the Krasnodar Territory are also made of straw. Rich people could build their houses even from Kara marble, but they build from straw. Why? Because straw is a bio-positive building material. What is biopositivity? Any material affects your biofield, the more energy of fossil fuels is spent on the production of building material, the more expensive and negative it is. How is this determined? If you take a control group of 10-12 people, measure their biofield using the crown laboratory method, now there are a lot of devices. You measure "to", put it for an hour in a reinforced concrete apartment, in a brick apartment, in a wooden house, in a gas silicate house, in an adobe house, and in a thatched house. They put him in for an hour, the person leaves, his biofield is once again removed, the second ones are subtracted from the first indicators of the biofield, and the result is averaged over the control group. You get a generalized effect of the influence of this type of building material and architectural form on human bioenergy. Here's what we got and what I was forbidden to publish: a reinforced concrete panel shrinks a person's energy in an hour up to 40%, a brick 25-30%, that is, even worse, it draws energy out of a person. Gas silicate is the same. The wooden house is neutral. The adobe house is neutral. The straw increases the energy of a person from 5% to 15% within an hour. There are things that medical beds can do. A straw panel can also be used as a treatment bed. Recently, research was carried out: people approached, the biofield was filmed, lay down for 10 minutes on a straw bed, after 10 minutes the biofield was filmed again. The minimum effect is plus 8%, the maximum is plus 58%, that is, the biofield increases almost one and a half times in 10 minutes. Imagine you are in a house where all the walls are made of straw, and the house is round, there are no corners that draw out energy, and you also sleep on a straw bed. Before telling or recommending something to someone, I always conduct an experiment on myself, making sure what and how. So my personal experiment is 3 years of life in a round thatched house in Belarus, our health was checked quite often by 26 parameters. Measurements have shown that for 3 years of life in a round thatched house, my biological age has decreased by almost 25 years. If before that my biological age was more than my physical age, then after 3 years of life it became almost 15 years less than my physical age. What is the reason for this? This is due to the fact that the impact of the biofield of straw on a person, plus the way of life, when you get up with the sun, lie down in the sun too, live in nature, you recover better than in any Kremlin hospital, better than any qigong and everything else. Therefore, such houses are curative and that is why very rich people now build just such houses for themselves. In Russian society, with our customers, it turns out like this: 15-20% are very wealthy people, and 75-80% are very poor people who do not have enough for a brick. Why? Because if you don’t have the money to make high quality finishes then you can buy a straw panel, it’s not expensive. And you will assemble the house in 4-5 days, and then you will slowly decorate it. That is, the technology suits both the very poor and the very rich. And in this respect, I believe that this technology is the future.

Mice in a thatched house
Very often people ask questions about rodents. In your experience, are rodents, in particular mice, really a problem in thatched houses?
K.N.
As 20 years of operating experience shows, and the first houses in the CIS were built 20 years ago, mice are not a problem if everything is done according to technology. Why aren't they a problem? In order for the mouse to make a move in straw, which is pressed with an effort of 4 tons, they need to spend 3 times more energy than in a tree. Kevlar vests work on this principle. That is, a Kevlar vest is a chaotic interweaving of threads and a bullet binds in them much better than in titanium and other alloys. Therefore, mice are not a problem if done correctly. There is no need to make any mouse nets. We used to do this, but then we became convinced that it is completely unnecessary. Straw Requirements: Straw must be covered on all sides. It is desirable with a non-flammable screed material. If this is done, then mice are not a problem. Screed in the form of clay, cement-lime or some kind of plaster.

Fire resistance of thatched houses
The second most popular question among people after rodents is fire safety in a thatched house. Is the straw burning?
K.N.
Is the straw burning? By itself, of course, it burns. Is the paper on fire? Yes, it burns. But if you try to burn a thick book, it will burn very badly already. If you plaster this book, it won't burn at all. If you cover the straw with a combustible material, then the fire resistance class is the same as that of wooden log cabins. If the straw is covered with non-combustible plaster 1.5-2 cm, then this is the ultimate fire resistance class. The tests were carried out in the USA, England, Germany. The limiting class of fire resistance is F-119, S-135. What is the F-119? This means that a plastered straw wall can withstand exposure to plasma with a temperature not lower than 800 ° C, while it does not transmit fire through the wall and does not lose its bearing capacity. Plastered thatched houses have the ultimate fire resistance class. Another question is that if there are wooden floors, then houses can burn on wooden floors. Therefore, special attention should be paid to the fire protection of wooden floors. In the spring of this year we had an international meeting on straw construction, and we adopted such a norm for ourselves that if we put straw on top of the floors, like insulation, then it is advisable to make a layer of self-compacting non-combustible material, for example, fine sand, expanded clay, oak leaves with clay, as our ancestors did, or something similar. The physical meaning: if drying occurs there and cracks appear, then, for example, sand automatically fills all cracks and the fire loses its ability to be fed by oxygen. Therefore, in terms of fire resistance, thatched houses are much safer than log cabins.

Economic benefits when operating a thatched house
It is clear that if you build a house from straw, according to technology, then this is not the cheapest construction. Can people, choosing a thatched house, derive any economic benefit from it?
K.N.
If you are building a thatched house, and you have enough funds, it will not look marginal, we will soon go to Krasnodar, see a very expensive thatched house, three-level, 500 m2, built 5 years ago, and ask a person why he built himself a house from straw ... A thatched house, if built correctly and done with sustainable finishes, costs the same as houses made of other materials, but you can save a lot on maintenance. Heating costs in a thatched house are 4 to 7 times less than in an ordinary brick house or any other house. This investment is very good and correct. Why? Because GAZPROM has taken a course towards the principle of equal profitability. What it is? Revenues from the sale of gas domestically must be equal to the income from the sale of gas abroad. That is, the price within the country will be pulled to the European level, and they are already being pulled. And in our country, unlike in Europe, the duration of the heating season is 3 times longer. Our climate is objectively 3 times colder than in Europe, so our heating costs are much higher. Thus, it turns out that it is necessary to invest in good thermal insulation. Why? Because in the future this will allow you to live comfortably, and even better to make a house that has no utility bills at all. That is, a house completely decoupled from central networks. In this case, the crisis is not a crisis, you have nothing to take, you have nothing but a land tax. Otherwise, you live and pay for nothing. There are a lot of such projects, there are also in the Krasnodar Territory, there are also near Moscow, there are also in Siberia. It is easy and simple to make a completely autonomous house now that fully complies with the passive energy standard.

Energy efficiency of thatched houses in numbers
What does the energy efficiency of a thatched house look like in numbers?
K.N.
According to German studies, the thermal conductivity of a straw panel is lambda 0.047 - 0.053 W / m3, the density of pressing is from 80 to 160 kg / m3. Thatched panel is 7 times warmer than brick, 4 times warmer than wood. We have here 45 centimeters wide, if you take a tree, then it is almost 3 meters. Heat loss through such a wall is less than 2%. In fact, such a house is a thermos. If we take the international coefficient, if we take the wall 45 cm, then it has a coefficient of 001 according to the German classification, if we take our system, then 10. The SRO now recommends 4, we do 10.

Breathable walls in a thatched house
How does moisture circulate in straw houses? The walls of thatched houses are breathable, what does that mean, please tell us.
K.N.
A very interesting phenomenon - even if you have not heated a thatched house for 10 years, mold never appears in it. This is in contrast to brick, concrete, gas silicate and other houses. What is the reason? In the fact that the wall is breathable, there is an automatic regulation of humidity: it is never too dry or too humid in a thatched house. By what means? If you are using natural clay plaster or clay-lime plaster, or cement-lime plaster (but there should not be more than 10% cement), then your wall is breathable, and it automatically regulates the humidity inside the house. Accordingly, the humidity is regulated and never reaches critical parameters. There is Darcy's equation: the higher the temperature, the higher the partial pressure of vapor, water. If you are warm inside, you have a high vapor pressure and the wall breathes easily. If an interesting phenomenon, we did a laser check, even at -40 ° C moisture enters, although it would seem that it should freeze at the dew point, but it does not freeze, it comes out and evaporates from the outer surface. By what means? Due to the fact that when moisture passes through the straw, the water does not form a short-range order. It turns out that a molecule with one end of water is always on the surface, in this case, a straw tube or straw pores. When water does not form a short-range order, it, firstly, cannot freeze, that is, it retains mobility at -40 - -60 ° C, and since Darcy's equation has not been canceled, if the concentration outside is less than inside, then the steam comes out, from warm to cold. Therefore, if you are doing it not with plaster, but with a vapor barrier, the film should always be written outward. It often happens that the floor is laid in the same way as on the roof, this is a mistake. It is necessary to do so that the moisture comes out from the heat. If you do this, then such a house is maintained in an optimal humidity regime in a natural way, which is very valuable. The best solution to a technical problem when? When the function is executed but the device is not. If such a solution can be found, then this is considered the best solution. Therefore, straw is the best solution for the building envelope of housing, office, industrial premises, and so on.

The durability of thatched houses
What can you say about the durability of thatched houses? Where did this technology come from, what examples are there, why straw can stand for a long time?
K.N.
There are thatched houses that have been standing since the century before last. I did not invent this technology, it was invented by the first American settlers who came to the Great Plains. There was nothing but grass. By that time, the first horse-drawn balers had already appeared, they were making straw blocks, as in "Well, wait a minute!" Many of these buildings have survived and are still functioning: housing, churches, and schools. They were built in 1896, 1901, 1904, I was there in those places. Many of them are even built from hay, not straw. Why do they feel normal? Because breathable plaster works like a reverse osmosis pump: all excess moisture will be thrown out. Usually they ask the question: "What about the dew point?" So, if water flows through the straw, it cannot form a short-range order, because it is absorbed into the straw, and there is no short-range order, that is, it cannot freeze, relatively speaking. How to make sure breathable plaster works like a reverse osmosis pump? If you have any pre-revolutionary or pre-war barracks, walk up when they are being demolished and see what happened to the wood. As a rule, the floors and logs have already rotted, and when the wall is broken, the tree under the lime plaster looks like it was put yesterday: it is sonorous, in excellent condition. Why? Because lime plaster, like clay or clay-lime, is a reverse osmosis pump. It draws all excess moisture out of the wood, even if you make it from wet wood. You can put either dry or wet wood in the panel, because the plaster will dry it out. The tree can only sit across the grain, but not along it. That's why it doesn't rot. Regarding durability, I want to reiterate that there are houses that are more than a hundred years old. If done correctly, there is no problem for a house to last for over 100 years. There is one more advantage that few people talk about: these houses have an optimal capital ratio. For example, what is the problem of demolishing five-story buildings that are obsolete in Moscow now? These five-story buildings can be demolished, and higher-rise buildings can be built in their place, but this does not work for economic reasons, because the capital of reinforced concrete is very large. To take it apart - iron separately, crushed stone separately - the cost will be $ 300 per m3. It is impossible to simply take it out and throw it into a landfill, as is usually done, because there are no more free landfill sites near Moscow. Long distance driving is also expensive. Moreover, from a five-story building, the landfill spot will be five times larger than the building spot. Therefore, the program for the demolition of dilapidated housing began to be done, but they ran into such problems. It passed as a pilot project, but it does not work as a system.

The strength of thatched houses
Everyone knows the tale of the three piglets, in which a wolf easily blows away a straw house. What can you say about the strength of thatched houses?
K.N.
A straw panel house or a frame filled with straw blocks are frame houses that use straw, a natural material, as insulation. You need to understand that the insulation is actually not foam, not stone wool, but air. With the help of straw or, for example, stone wool, we simply stop the movement of air. In my opinion, it is much better to stop the movement of air using natural, natural materials without any chemicals and harmfulness. As for strength: the use of a fortieth or fiftieth board in the frame allows you to build three-story houses without any problems. Houses can withstand all kinds of hurricanes, earthquakes, and so on. In terms of earthquakes, such a house is much safer than a panel, brick or any other, because it is difficult to kill a person with a straw panel. Such a structure is very easy for shock waves to pass through, it does not collapse, because the tree bends easily, and the shock waves pass. Since the house is light, the foundation is very light. In Sochi, we build houses on any slope, 45-60 degrees - please. We easily build a house, asbestos-cement pipes are made, reinforced, poured with concrete, and this is designed for a 10-point earthquake. Everything else that is being built in Sochi is 8 points. What is the danger? If there are 9 points, then with a guarantee no one will come out of the panel house, because the reinforcing belts, which should be kept from destruction, will burst and the effect of a compressed spring will occur. In a house made of straw panels, there is no danger, because the shock wave easily passes, the foundations are light, stable. I carried out construction in Denmark, Germany, what is the difference in mentality in Russia and in Europe? In Germany, for example, a person is ready to pay double the price if he understands that the house will be environmentally friendly, will not destroy his health, and will not destroy the health of his children. This is not the case in Russia. In 2000, 30 people from Germany studied with me, and in fact everyone created his own company and everyone builds such houses. But there this direction is supported by the state, and people are ready to pay for the environment. In our country, no one is ready to pay for the environment, even more than that, I’ll tell you: in Russia there are no maximum permissible concentrations of harmfulness for housing. This is a paradox. You can make a house out of what you can't live in, and very often it happens. Recent scandals in Moscow, when new nine-story buildings were being dismantled there, because for seven years there has not been a single normal pregnancy, and all building materials are approved and have hygienic certificates. How can this be? The state allows this on the market, but you cannot live in it. Either something in the state is not right, or the goals are different, or some other reason. What is the principle: if you use natural natural materials, then you do not need to know any maximum permissible concentration. As soon as you go into chemistry, supposedly harmless, which does not exist, problems immediately begin: allergies and so on. Therefore, this direction is the future.

Cold bridges between straw panels
Is heat lost in a house built of straw due to interpanel joints?
K.N.
What are the constructive options for performing panel walls, so that there are no cold bridges, there is no infiltration through the cracks, and so on. There are several approaches. The first approach is plaster. Plastering is done like this: a mesh is pulled out and plastered on top. In this case, the gap is under the plaster and has no effect on the infiltration. If you are making a finishing material, for example, thermally insulated pine, you definitely need wind insulation. Already there is not a mesh, but wind insulation, necessarily breathable, after - a finishing material. If you do not have either one or the other, you want to leave the straw so that it works as efficiently as possible on your biofield. There are also such options: you need to lay a jute or linen pad, what is used when laying log cabins, and screw it up. It turns out that the gap is filled with jute. These are the solutions.

Bio-positivity of thatched houses
Many people do not understand the term "biopositive material". Could you, please, reveal what are the bio-positive properties of straw?
K.N.
What is the physics behind the biopositivity of such a pressed straw wall? When I was in Siberia, hunters told me a trick that is used when hands freeze so that it is impossible to hold a matchbox, and there is a real danger to life - you cannot light a fire. What should be done in this case? In this case, a tinder fungus is found, the gloves are removed and the hand is brought under the tinder fungus at -40 ° C. After one and a half two minutes, the hand begins to move. Why? Because at the bottom of the tinder fungus there is a very porous structure of tubules in which there are spores. These porous structures create a specific field that affects the qi and activates the qi movement in the channels. If the qi begins to move actively, the lymph will move after this, the blood will follow the lymph, and the hands will acquire mobility. In a thatched house, the entire wall is such a tinder fungus. Or, let’s say, the bed will give the same effect: you go to bed and you have an intensification of the qi movement. Qi is the energy that falls on us from space, we are familiar with it mainly from the Chinese qigong gymnastics, which is aimed at activating the movement of qi in our body. Qi is cosmic energy, gong is movement. Thatched wall, especially when the house is round, is the factor that strengthens your biofield by intensifying the movement of qi. It is basically a mechanism that allows one to obtain therapeutic effects, health-improving effects, up to the treatment of psychosomatic and mental illnesses. The Germans who studied with me in 2000 created a department of mental problems at the Munich Institute of Parapsychology, in which they treat deep depressions by putting a person on straw, making a straw hemisphere, putting on headphones and fixing alpha, detail, beta, gamma rhythm of the brain. First, he hears bells, and then there is harmonious music and they watch until all his biorhythms return to normal, like a healthy person. This takes 1.5 to 5 hours. Then he puts 1500 € in a box, and gets a guarantee for six months that he will not get depression. Such treatment is quite effective and has already been tested in Europe. Although our grandmothers used it. Ask your grandmother which mattress was considered to be healing, she may not explain “why?”, But which one she will tell you for sure - a straw one. It was possible to sleep on a feather bed, but generally slept on straw, because the biofield on straw is very efficiently restored.

Straw eco houses idea, healthy lifestyle concept
A real eco-house is not just a straw house, it is a connected house-plot system. You can, literally, in a nutshell, reveal the concept of a healthy lifestyle. What is the idea behind building eco houses?
K.N.
How are we different from other construction companies? We try to solve the issue comprehensively, that is, not just build a house, but create a “house-plot” ecosystem. The most important thing is the local permaculture sewage system, which would convey the energy information of your health status to your plants. The Creator arranged it so that the lower serve the higher. If plants receive energy information about the state of a higher being, and we are higher beings in relation to plants, then they are obliged to produce substances that are medicine. It was written in Ayurveda 9 thousand years ago. How to do it cheaply, simply and efficiently? If they order us a house and order such a system, then we design it right away. If you want, we will do it ourselves, if you don't want to - hire Tajiks, and in 3-4 days they will make such a system according to our drawings. It turns out that you pulled the handle of the toilet bowl and you started to irrigate the area underground. Your waste undergoes aerobic, anaerobic, again aerobic purification, and then the water, in fact, already purified and structured, filled with nutrients, goes to your plants, and the yield increases significantly, and the fruits are medicine for you. Plus, I have already spoken about the house as a place for the application of labor. It is important to build not just a house, but it is important to build a house and something to support the family. You integrate into the social division of labor by growing fruits, vegetables, mushrooms, in a word, whatever you like. It is important to understand the boundary conditions, you need to understand that the Krasnodar Territory, South Siberia, the Central part are now very much sprinkled with chemistry from the civil aircraft of American and Turkish airlines, NATO aircraft have a base in Ulyanovsk, they are also sprinkled with powder. Therefore, when you make systems that provide you with food, it is very important to protect them from what is falling from above. We give recommendations on how to do this, develop drawings, how, for example, to make a greenhouse around a house that would cover your needs, and at the same time keep the soil clean. Because their task is they have now made lines of plants that are resistant to aluminum salts and mercilessly pour this aluminum so that natural plants simply do not grow. Who cares, go to the Internet, Galina Tsareva's film "Haarp - climatic weapon", the second part, or simply "chemtrail", there will be a lot of information. All this must also be understood, and we take this into account when we make such systems.

Straw green building and ecology
It is clear that straw has a very beneficial effect on human health. And what can you say about the impact of straw construction on nature, on the environment?
K.N.
Ecology of impact on nature. In Russia, about 100 million tons of straw are burned annually. Because there is no adequate straw recycling technology. Sometimes they put drum grinders on the combines, which grind the straw into dust, but in this case the fuel consumption increases by 30-40%, and the farmers already live in a "pressed" state, and they are not interested in increasing the consumption of diesel fuel by almost one and a half times, for to grind the straw. It turns out that the straw remains in the field and is then burned, there is practically no bedding for livestock now, everything is on the manure water washout. When straw burns in the fields, it is clear that nothing good happens: smoke, destruction of entire ecosystems of insects, small animals, and so on. This is on the one hand. On the other hand, rice straw in the Krasnodar Territory is a big problem, because it doesn’t go anywhere, even to bedding cattle, and it’s not clear what to do with it. In general, the technology of building houses from straw will allow solving the housing problem in the country in 2 years. But there is no interest, because there are established financial flows, formed, and changing them is fraught with consequences. Everything has already been divided, so to speak, so there are always people who do not like it very much. Now for the third factor. We have already said that when a reinforced concrete five-story building "dies", it is not clear what to do with construction waste. In Germany, this is also a very big problem, because 10 million tons of construction waste appears there every year. You cannot bury it in the ground, because it is, as a rule, bent reinforcement, concrete; it is very expensive to process it so that the crushed stone is separate, and the iron is separate, is very expensive. When the straw has served its life, it was thrown out in the field, and the natural circulation will go. Also clay plaster. Everything here is completely renewable, ecological, without any chemicals. What's the bottom line? Production solves environmental problems, recycling does not create environmental problems, in the process of operation a person strengthens his health. Why not use this technology?
What are the difficulties at the moment when building a thatched house?
K.N.
There are not so many specialists in the construction of houses from thatch panels now. Although people receive information via the Internet, they themselves begin to assemble machines and make panels. This is not bad, but a house is such a thing that it is better to learn from the mistakes of others from professionals, or to attract specialists to build such houses. The Razekodom company is the first in Russia to build three-story houses from straw panels, built in Siberia, the Volga region, and near Moscow, in the Krasnodar Territory. There were also one- and two-story round houses, also made of straw panels. The results are good. Everything that I said about the timing and technology has been tested by practice, this is not a fantasy, but the reality of our days. Therefore, contact the specialists.

Steps and timing of construction of thatched houses
If a person has already decided to build a straw house for himself, how should he proceed further? How long does the construction take?
K.N.
What is the scheme of work? If you have a plot, then before building a house, you need to find out what you have with the energy patterns on the plot: how the sun goes, where you have aboveground, underground water. In straw panels, the compressive force is 4-5 tons, ventilation cannot be even theoretically. Everything costs very quickly. There is one more factor: with the same estimate, if you build quickly, your costs are significantly less than if you stretch this pleasure for 3-4 months. So, the foundation is about a week, the house is assembled in 3-4 days without a roof, the roof is made for a week, and after that you can start finishing. The ecological quality of the houses is checked and certified. We build everywhere: in the Krasnodar Territory, in the Urals, in Omsk, in Moscow, in St. Petersburg, the Volga region. In a word, all over Russia. I was often asked to build a village of 100-150 houses per season. Last year I had to refuse. Because I worked with straw blocks, and with the number of specialists at which I could guarantee quality, the maximum could be counted on 10-15 houses per season. Couldn't do any more. Now, with a more modern construction technology from straw panels, you can build both 100 and 200 houses. This is already a fairly high quality and fast enough construction. You can also make round houses from straw panels, rectangular, oval, whatever.

Terminology
The most valuable thing in a person's life is his health. Everyone understands that it is impossible without a healthy lifestyle. Many environmental factors affect human health. What we eat, what we drive, where we live are all crucial.
A healthy lifestyle is impossible in an environment filled with harmful substances. Therefore, in the pursuit of health, we come to the need to use environmentally friendly building materials. Unfortunately, many of those who prioritize a healthy lifestyle do not see the difference between environmentally friendly and sustainable materials.
Environmentally friendly materials are called materials that do not have a detrimental effect on the environment. But only those materials that do not cause any harm to the environment at all can be called absolutely environmentally friendly.
On the need to use straw
The use of environmentally friendly materials is not a sufficient measure to preserve the environment. The fact is that when creating such materials, technologies that harm nature are often used. For example, when using different devices and units, the demand for electricity increases, the production of which can be associated with "dirty" processes. In addition, the amount of resources required to sustain production increases. This includes the creation and use of lubricants, spare parts, as well as waste from related production processes.
Brick, mineral wool, natural stone and other environmentally friendly building materials require a lot of energy and resources to manufacture. The use of wood, as one of the most environmentally friendly materials, leads to the rapid reduction of forests on the planet. Therefore, using wood is not a sustainable approach to construction.
Combining convenience and environmental friendliness
The logical conclusion is to reduce the amount of wood in the construction of buildings to the minimum possible. This issue has already been partially resolved - "frame" construction is gaining more and more popularity. The share of wood used in this technology is only about 15% of the total wall material.
(Compare this with a house made of logs, in which wood makes up 100% of the material. To build one house with an area of 150 square meters, you need to cut down a quarter of a hectare of forest. For reference: it takes 30-50 years to grow a tree suitable for cutting six-meter boards).
The walls of buildings with frame technology consist of wooden "ribs", the space between which is filled with some kind of insulation. Most often it is mineral wool or expanded polystyrene, better known as polystyrene foam. And he and the other insulation can not be called environmentally friendly. During operation, they can emit harmful substances into the atmosphere. In addition, the installation of mineral wool insulation is fraught with the risk of damage to the skin and mucous membranes of a person.
Perhaps the only insulating material that has the right to be called environmentally friendly is ordinary straw. It is an annually renewable resource. Moreover, it appears as a by-product in the cultivation of cereals.
Therefore, there is no need to create a separate production facility for straw. After all, straw remains on the field after harvesting - wheat, rye and the like. You just need to collect it.
In the production of wall panels, it is most advisable to use rye straw. It is not suitable for the household - due to its rigidity, it is not even suitable for flooring in animal housing. Often times, it just stays rotting in the fields. In addition to this, the straw has excellent sound and thermal insulation qualities. It is three times more effective than pine wood and 10 times more effective than brick.
Consequently, rye straw, as a raw material for construction, has three key advantages: annual renewability (remains in the fields), lack of energy-intensive production (costs only for collecting straw) and fiber structure (thermal insulation). Thanks to these advantages, straw insulation is out of competition in terms of environmental friendliness compared to other materials.
History reference
People have been using straw to build houses for thousands of years. The first mentions of thatched houses (in surviving sources) have come down to us from ancient Egypt (about 5000 BC). Since then, the technology of straw housing construction has come a long way from adobe houses to multi-storey buildings with straw insulation.
Initially, these were walls made of straw, covered with clay for strength and weather resistance. Then there were houses built of bricks made from a mixture of straw, clay, sand, earth and water. Later, straw pressing was invented, which made it possible to erect the walls of one-story buildings from straw briquettes, and then cover them with plaster. To date, the development of technology has come down to the creation of wall panels with straw inside, ready to be installed and formed walls.
Today straw technology is used in many areas of Eurasia (from Kuban to Great Britain), North America (USA, Canada) and others.
Not afraid of water or teeth
The straw, which is used as insulation, does not rot. Firstly, the rye, which has not yet been harvested, is washed by the rains and then dried by the wind. Secondly, it is collected only in dry, sunny weather. Thirdly, after being pressed into the wall panel, the straw is plastered on both sides with a layer of moisture-proof material: clay or gypsum. This plaster protects from moisture, but at the same time it is perfectly vapor permeable. Thanks to this, the straw insulation is highly durable.
In addition, rodents do not grow in rye straw. There are also several reasons for this. The first is that the straw goes to the production of panels after harvest. They are simply dry stems left over after threshing, freed from leaves, inflorescences and seeds. There is nothing for rodents to eat in this straw. The second is that the straw contains a substance called lignin, which rodents do not like very much. The third is rye straw so hard and prickly that it cuts the skin. Therefore, straw is not suitable for living either - it is uncomfortable to sleep on it.
In addition to this, straw contains 2-3 times more silica than wood. This makes it more durable and resistant to fungal attack.
Brief description of technology
The straw is collected from the field using an automatic baler. It leaves behind bales that the workers manually load onto the tractor body. After that, the straw is delivered to the edge of the field, where it is transferred to a truck that carries the straw for the production of panels.
At this time, the assembly of the frame for the panels is in progress in the workshop. Using pre-prepared boards (dried and sanded), frames of future panels are formed. Then the straw is pressed into the assembled frames to a density of 140 kg / m3. With this degree of compaction, the straw becomes a completely non-combustible material.
When creating one standard wall panel 1.25 m wide, 2.5 m high and 0.42 m thick, 15 rectangular bales of 30 * 50 * 80 cm are required. Taking into account the weight of the dried wood, the finished panel weighs 230 kg. The plastered panel weighs almost 600 kg.
The last step in creating a wall panel is to cover the front sides of the panel with plaster. At the same stage, cable and ventilation ducts are laid in the plane of the wall. As a result, a finished panel comes out of the production line, suitable for installation of walls or ceilings on a construction site.
Such panels allow building houses up to 3 stories high. If, when assembling the panel, add metal to the wood, the number of storeys of the building with straw insulation can be increased to 5 floors. Such houses are very common, for example, in Germany.
A building made from such wall panels can withstand a magnitude 10 earthquake.
Assembling a finished house
Wall panels assembled using the latest advances in straw construction have such important qualities as durability and reliability. They are carriers in themselves. In addition, the technology allows you to customize production for the production of panels of various formats.
Thanks to the proven technology, the finished panels are easy to install, and also have a primary finish. You can immediately attach decorative elements and light furniture to the side of the panel facing the inside of the house.
The technology allows assembling the house at any time of the year, observing the only condition - dry weather.
Water and fire are not afraid
The plaster used to cover the straw consists only of natural materials. Its main components are gypsum or clay, which have the same properties. Other components of the plaster serve to give it rigidity - salt, lime, or are added as heat-insulating fillers: chopped straw, sawdust, sand, vermiculite, expanded clay.
In addition, the clay additionally preserves the entire structure. They say that thanks to this very property, several decades after the construction, dismantling such a house, a tree that has not been spoiled by time is found in the thickness of the wall.
But clay has another unique property: it maintains ideal humidity in the room, absorbing excess moisture or giving it back if necessary.
The fire safety class of the wall panel is K0 (30). This means that the plastered panel will withstand exposure to open fire for 30 minutes. Only then will the straw insulation inside the panel heat up and begin to smolder. The straw will stop smoldering without further heating.
The humidity inside a panel house with thatched insulation is maintained within the range of 40 to 60%. This indicator is comfortable for a person in the warm season. Consequently, the humidity inside such a house will be comfortable all year round.
It's easier today
For a long time, construction using straw was very time consuming. Collecting straw, laying in walls, covering with clay - all this required a lot of time and effort on the part of the builder. Forming briquettes from straw using a baler right on the field did not save the builder from manually laying briquettes to form the walls, as well as from plastering. Now - with the presses in the shop - the panel assembly process has been greatly simplified and accelerated.
Thatch house building is the most environmentally friendly.
A home built using thatch has many positive aspects. Straw insulation does not require high energy consumption when creating. Straw does not create any inconvenience during installation, like mineral wool insulation. It does not emit harmful substances and does not serve as a pollutant remaining after construction.
In addition, straw has excellent sound and heat insulation. It is the best foundation for creating a passive, self-contained home. It allows you to significantly, up to 50%, reduce energy consumption for maintaining the temperature. According to statistics, 27% of the energy generated in the world is spent on space heating in cold seasons and cooling in warm seasons.
Considering all the listed features of straw insulation, we can conclude that this is an absolutely biopositive material. Its extraction, production, use and disposal do not cause any harm to the environment.
To keep up with the times
A house that uses rye straw for insulation is not just environmentally friendly. Such a house will be the most energy efficient and environmentally friendly of all. By building such houses, we protect nature from pollution. Thanks to the development of technology, today's house with thatched insulation has nothing to do with the hut, which crumbled from the wolf's breath in the famous fairy tale.
Life goes on, technology develops, straw grows, houses with straw insulation stand and delight their owners. Realizing the value of the environment, you need to arm yourself with the fruits of technology development and keep up with the times.
