All you need to create is Instruction + Video and Photo

All you need to create is Instruction + Video and Photo An autonomous house is its own master in a private household. In Russia, many people began to pay attention to this type of construction as an autonomous house, which is popular in the West. As a rule, most of the information began to be learned from news about such unique buildings. Everyone saw beautiful pictures, as well as stories about how efficient and modern the house is, and how pleasant it is to live in it.

By virtue of the profession, many construction companies keep a close eye on the latest developments in order to fulfill any wishes at the request of customers and build a dream home.

The indispensable attributes of the construction of a modern house is an increase in efficiency in solar panels, cost reduction, efficient heat pumps and solar solar collectors, heat recuperators and solid fuel boilers, as well as energy-saving technicians and modern construction materials. Sooner or later, the experience of implementing income is up to us.

General information

Let's look at the very concept of "autonomous house". It is a house that is independent of city communications. Later in the article you will learn more about this concept.

What does living in a house depend on? To begin with, let's find out what ordinary houses, to which we are accustomed to, depend on:

  1. From electrical energy ( the nearest RES).
  2. From gas supply ( the nearest regional gas).
  3. From sewerage and water supply ( your local water utility, if available).

As a rule, it is possible to resolve the issue of water supply and sewerage without the direct participation of the local water utility - this will require drilling a well and equipping a cesspool or septic tank, so we will not consider this item in detail. Let's talk about something more important.

Gas - most often it is used to heat the house and heat hot water. Electrical energy - for the operation of all electrical appliances in the house (and sometimes for heating). Now it is worth considering the pros and cons of a house, which is also called a volatile home.

Advantages Disadvantages
  1. Relatively inexpensive electrical energy.
  2. Cheap gas (depends largely on the category of consumers).

  3. Comfort (everything will work offline).
  4. The equipment is compact, does not take up much space.
  1. Typically high costs for gas and electricity connections.
  2. Binding to the area when building a house, namely from the location of communications.
  3. Waste of time for agreement and approval of the project and the accompanying documentation.

  4. There is a chance of electricity and gas outages due to economic, political and technical reasons.
  5. The quality of power supply is not always the highest.
  6. Constant increase in utility bills.

The list of advantages and disadvantages of the house was taken from the experience of the builders and customer reviews.It could have been larger, but only the major milestones were taken into account.

What is the difference between a standard house and an autonomous house?

First, you need to consider how, using available modern technologies, we can replace the standard processes taking place in the house with autonomous ones, which will not depend on networks.

Electricity

According to the average statistical data, one residential building uses from 200 to 300 kWh of electric energy per month. Such a need can be replaced with the use of an autonomous power supply system at home in the form of solar panels (which will come complete with a diesel or gasoline generator) or with the help of a solar-wind station, in which two sources will operate simultaneously.

Since it is in the summertime solar insolation has the highest rates in summer, and the wind will blow with great force in autumn and winter, this combination of two sources will be an alternative and optimal option - the sun and wind complement each other perfectly friend all year round.

A typical solar station of an autonomous type consists of:

  • All you need to create is Instruction + Video and Photo Solar batteries / panels, which are placed on the roof of the house and in them, depending on the rated power, will occupy from 10 to 50 m 2 .

  • The charge controller, it charges the batteries, and is located indoors.
  • Inverter, it is he who is responsible for converting DC voltage from the battery to AC with a value of 220 V.
  • Batteries, being a storage of energy, which was received in a day from solar panels.

If you use a wind-solar station, then you need to add a wind generator and a mast to the scheme, the height of which can be from 18 to 24 meters.

Hot water / heating

You can provide your home with constant hot water using a solar collector, which will bring energy from solar radiation in the form of thermal energy and then accumulate in a special storage tank.

For a small house with an area of ​​100 to 140 m 2 , the size of the collectors on the roof will take from 5 to 10 m 2 , and the storage tank will have a capacity of 200 to 500 liters.

Taking into account the fact that the intensity of solar radiation in winter is several times lower than in summer, the system will 100% cover the need for hot water in the warm season, and in autumn and winter only by 60%, leaving water heating and for another heat source.

There are several options for heating an autonomous house. Now there are two main approaches to solving this issue. The first option is to use a solid fuel boiler, and the second is to buy a heat pump.

As a source of autonomous type for an insulated house, it is advisable to purchase a solid fuel boiler that can also run on wood. And on pellets, fuel briquettes and biofuels. It may seem to you that there is no autonomy.

In fact, the boiler in any case should consume at least some fuel, and this is quite natural, but believe me, if you correctly design a boiler room and heating system in the house, choose a boiler that you do not need will fit every day. Thanks to modern fuel supply systems, you can completely automate the process.

Naturally, one cannot do without cons, namely storage of firewood, purchase, but it will be much safer and more predictable than using gas or electricity. The use of a heat pump in an autonomous house, in which electrical energy will be obtained by alternative methods, is recommended only in well-insulated houses, which will be discussed further.

Conditioning

When using a standard solid fuel boiler, air conditioning will take place according to the classical method by means of energy-efficient split systems. If the heat pump is used as a heat source, it can be used in reverse mode in summer to cool the air in the house. It can be active cooling with the compressor running or passive cooling due to the coolness of the earth.

Energy efficiency

Separately, we note that in a standard house most of the energy consumption goes just for heating. Based on these data, you will see that with a decrease in the consumption of electrical energy for heating, it will be possible to heat less. To do this, your house must be well insulated, as well as competently designed and built to last. The main task during construction is to create a house that will save energy well.

Passive houses have gained particular popularity lately.

These are special houses in which energy consumption and consumption are minimized. If in a standard house the energy consumption (heating + all electrical appliances + hot water) is from 200 to 300 kW * h / year * m 2 , then in a passive house the value will be up to 15 kW * h / year * m 2 . As you can see, when building a house using a new technology, the energy demand will be reduced by more than 10 times!

In Germany, such houses have been built for more than 20 years and they have proven themselves from the most comfortable and profitable side. From the beginning of 2020, all new buildings will be built in Germany using this technology alone. What is it all for?

In addition to the fact that with a significant reduction in energy losses at home, complete autonomy will be able to show itself in all its glory.

The house will become completely autonomous, comfortable and modern.

All you need to create is Instruction + Video and Photo With small heat losses, you can abandon the solid fuel option for heating an autonomous house and opt for a heat pump that will work from electricity that is generated from a wind-solar power plant.

Due to the fact that the need for electricity is not so great, the purchase of a powerful heat pump is not required, and this is also a cost saving.Since the power consumption of a warm pump is not very large, the power of solar panels or stations can also be chosen of a moderate type, and this is also a direct saving.

The main methods to reduce energy costs at home

  • The use of solar panels is passive due to the building's orientation to the south and the absence of any type of dimming.

  • Thermal insulation of the house to the maximum and use of high-quality materials during construction.
  • Use of energy-saving appliances, consumption class A ++.

Comfort and freedom of choice

With all the systems of an autonomous house, you will have the freedom to choose any site for construction. The house can be placed where you want and not overpay for a plot of land on which there are all standard communications. It will always be comfortable in such a house with the latest technologies, otherwise there would be no point in using them.

With the correct calculation of all systems with specialists who can "make friends" the work of all systems, you will become the owner of a harmonious system that can satisfy all needs.

Wind and solar power plants, solar systems, heat pumps and solid fuel boilers - this is all that has long been tested and is successfully used in Ukraine and Russia at a large number of objects. And now you can summarize the results, advantages and disadvantages in one small tablet.

Advantages Disadvantages
  1. Possibility of placing the house in any convenient place for you .
  2. Saving money and time for connecting communications (gas, water and electricity).

  3. Independence from suppliers of resources (regional gas, local water utility).
  4. Independence from tariff increases.
  5. You do not need to pay bills.
  6. Modernity.
  7. The best value and investment in a future free home maintenance.

  8. You can sell excess energy to the grid at a green rate (if there is an electric grid nearby).
  9. Perspective.
  1. There is a possibility that engineering systems will rise in price.
  2. When using a solid fuel boiler, you will have to buy, deliver and allocate space for storing fuel.
  3. When using a heat pump, an area for placing the heat exchanger on the ground is required.

Where to start?

Now you know which autonomous systems are separately composed of an autonomous house, but how to start construction?

  1. All you need to create is Instruction + Video and Photo First, decide if you need a plot with communications. If not, then buying a land plot will be much cheaper.
  2. After we will solve the issue with the area of ​​housing. With the same budget, you can build a house for both 300 m 2 and 150 m 2 . In the second case, the house will be more technologically advanced and more modern.

  3. Do not forget that even well-insulated houses will consume about 200 kW * h / year * m 2 (not to be confused with a passive house). The larger your home is, the more you will spend on maintaining it. With prices constantly rising, this can come as an unpleasant surprise.
  4. Remember that the money invested in insulation will pay off faster than energy efficient equipment.
  5. If you want to leverage new technology, look at how it fits.

    Engineering solutions are discussed first, and then design. discuss with experts what engineering systems can be used in your home and what area they will occupy, where it is better to place. Only then can the project be approved.

  6. If this is your first time building a home, try to hire as few contractors as possible. Since you are not an expert, it will be difficult for you to figure out where the powers of one end and the responsibilities of the other begin.

    As practice shows, it is much easier to ask everything from one person. That being said, find out if you can buy materials in one place to get a discount on bulk purchases.

  7. The guarantee of effective use will be the responsibility and professionalism of specialists. Clarify the possibility of a bundle of all technologies and creation on a turnkey basis,
  8. Try to find such masters who will answer all your questions in understandable language. Do not hesitate and ask them to talk about all the advantages, disadvantages and pitfalls.

    You have the right to ask about everything and more than once until the complete picture is formed.

Conclusion

Summing up all of the above, we can say with confidence that an autonomous house is not something from the realm of fantasy, but a real, modern and energy-efficient solution , for the implementation of which it will be necessary to correctly calculate and design everything. Only with the proper integration of all systems will you get the desired result.

As the experience of European countries shows, energy resources are the gold of the 21st century. For this reason, everyone is trying to race to develop new programs for the introduction of such energy sources that are renewable, and energy conservation is being promoted even in children's institutions.
