What you need to know about energy-efficient technologies

With each passing day more and more people think about the use of energy efficient technologies. This is not surprising, because each of us wants to live in a warm and most importantly - eco house. Forumhouse.ru will tell you - what materials and technologies are used pristroitelstve energy-efficient homes.

So,

• What is it - the energy-efficient house?
• What materials and tools to build warm and comfortable home you can offer the modern market of building materials?
• Do you know all about the energy efficiency project for your future home?
• How to reduce heating costs already built house?

Energy-efficient house - it's ...

What is the meaning we put into the phrase - energy-efficient house?

According to the company manager TKDomAlexander Vodovozov - energy-efficient house - a building in which all the minimized energy losses and power consumption. The basic principle of the construction of energy efficient homes is to achieve maximum tightness homes, the use of energy-saving technologies and the elimination of thermal bridges.

In Russia, the main energy consumption falls on heating, so the main task is to prevent heat loss through the building envelope the house - floor, walls, windows, floors and roof. This can be achieved with the help of modern technology frame construction. Through the use of heaters and special methods of sheathing frame completely eliminated the presence of cracks.

Thus, for the construction of energy-efficient home should:

• Warmed to build the foundation. In frame construction, similar to the foundation still plays a role, and the storage tank;
• To establish a highly efficient ventilation with heat recovery system. Since lost through the ventilation 30-40% of the heat, the application of such a system will significantly reduce the energy consumption for heating the supply air;
• Locate living rooms in the southern part of the building. Which will use solar power as an additional source of heat;
• Produce the maximum insulation walling. It is through these major heat loss occurs.

But often, developers just do not want to invest in additional insulation, believing that it will lead to an increase in the cost of erecting the building. So whether to build energy-efficient house is beneficial?

Alexander Vodovozov:

- If we talk in terms of figures, the construction of energy-efficient house costs about 15% more expensive than usual, but in operation it is cheaper by 60-70%.

We can say that the construction of energy-efficient home is a complex undertaking, which can conserve your cash for the foreseeable future.

Foundation "warmed Swedish stove" - ​​as the basis for energy-efficient homes

It is believed that the additional insulation of the foundation a waste of resources. But is it really?

Seek clarification from the technical specialists "TECHNONICOL"Developing special materials for energy-efficient homes Anton Borisov.

- Heat losses occur constantly, distinguish only the intensity depending on the type of construction. For example, the highest heat flux passes through the upper roof structures, due to the density of warm and cold air. The warm air tends to rise upwards, together with the dragging and thermal energy. Also, there is large and the heat loss through the foundation.

All the heat loss can be divided into heat loss that can be prevented and those that lend themselves to a slight reduction! For example, the heat losses through the foundation on average 10-15% of the total heat losses of the building. Therefore, the construction of energy efficient homes must begin with the construction of insulated basement.

Anton Borisov:

- One of the most effective ways to reduce energy consumption for heating the building becomes the construction of houses on the type of foundation "Insulated Swedish stove". For this purpose, use extruded polystyrene.When selecting a heatershould pay attention to the rate of heat conduction. The smaller, the better, since a smaller thickness require insulation layer.

When energy-efficient device of plate bases should also be aware of such an important index - as the compressive strength of insulation. Since these foundations are insulated from the bottom, the insulation should withstand the weight of the whole house, with all variable loads!

Selection of optimal insulation thickness

It lost through walls up to 20-30% of the heat. What is the thickness of the insulation must be selected for the construction of energy-efficient home?

Tatiana Smirnova (Head of Design Center ROCKWOOL):

- The first layer of insulation thickness will depend on the structures of the building. If the frame technology, for the Central region of Russia, the recommended standards insulation thickness is 150 mm, and the optimum from the point of of energy efficiency will be the thickness of 250-300 mm, then the construction of the house of foam, the effective thickness will be 150-200 mm, while the regulatory 80 mm. Roof should be used not less than 250-300 mm of insulation. In addition to an optimal thickness, it is necessary to take into account when choosing insulation, insulation that is available for the use of different brands in various building structures, wherein each product type decides a specific task and responds appropriately requirements.

The construction of energy-efficient home requires a balance between the cost of materials and high-quality thermal insulation of walls and roofs. Therefore, there is no need to increase the insulation layer by more than 30% from the recommended value. Otherwise, the estimate increases, and the project becomes unprofitable.

The thicker the wall - the warmer the house?

Meaning the energy efficiency of a private home you need to think not only about reducing domestic consumption energy, but also on additional ways to heat accumulation that will reduce costs heating. There is a misconception that the thicker wall masonry house under construction, so it will be warmer, but is it really?

Consultant FORUMHOUSEPavel OrlovRepresenting the company Smart Story He believes that - the energy efficiency of a building is only slightly dependent on the material and wall thickness. There are principles and technology to be used in design and construction. A home energy efficiency will primarily depend on the thickness of the insulation used.

So what principles and techniques still need to be guided in the construction of energy-efficient home?

Pavel Orlov:

- First of all, the developer needs to understand that the basic principle of the construction of energy efficient homes is to heat energy savings. Modern technologies allow to reduce heat loss at home, to the value of internal radiation from people and appliances. Severalcomplicated things with electricity and hot water. Their consumption is usually much lower can not, t. To. They mainly depend on the habits of the hosts and have a direct impact on the comfort of living.

Also, it makes sense to consider the following points according to Paul in the construction of energy-efficient homes:

• The potential customer must first order the project in a major engineering company, with experience in the design of energy-efficient buildings;
• At the design stage, it is necessary to provide for the use in the construction of modern forms of insulation at home. In this way we lay the high value of heat transfer resistance;
• Since the windows are lost approximately 15-25% of the heat, it is necessary to use glazing with double-glazed windows of the three with argon filling.
