WHY WE NEED ENERGY UPGRADING?

We build houses in a pleasant and healthy climate to create rooms. But is it exactly that the conditions of being nice? What a pleasant room climate we feel it can not be too hot or too cold. The air humidity should feel uncomfortable, but it is not pleasant, when the air is too dry.

Generally, 20 to 22 degrees around room temperature, and the corresponding air 50-70% relative humidity feel comfortable. If the wall surface temperature is higher than 18 degrees to 20 degrees around the room, or even less pleasant temperatures judge.

II. After World War II, but mostly in the 70s from the comfort of the demands placed fundamentally changed.

The insulation improvements only after the mid 70's took place (in our country it arrived much later) so the increase in demand increased comfort space heating energy consumption in reverse. Therefore, it became clear that the heating energy consumption, reduce our need! The comfort we do not want to give up, so it's just more efficient use of energy, advanced technologies available!

For this purpose, as well as in the previous article in detail the requirements of the raises, legislators have created here at home in 7/2006 TNM regulation, the definition of energy performance of buildings.

The regulation of buildings and doors bounding structures of the heat transfer aspects of the customized requirements. A building element hőátbocsátásának measure of overall heat transfer coefficient (U value). This is the type hőáromot Watts, 1 K temperature difference is when a food is based on my m2 surface flows. It is expressed in W/m2 * Tues The lower the U value the better the thermal insulation of building elements, and the less the resulting heat loss.

Some of the most important limiting factor for heat transfer mechanism required value in the table below:

U overall heat transfer coefficient value of the structure required W/m2K

• External walls 0.45
• Flat roof 0.25
• 0.3 Attic Floor
• Facade glazed windows (wooden v. PVC ed.) 1.6

The thermal conductivity λ is a set (building) material properties of specific heat to drive. It is expressed in W / m * Tues The smaller the value of λ the less drives the heat flow, so the better the insulation meets the building. The value of λ such as mineral wool 0.040 W / m * K poliuretánhaboké 0.030 W / m * Tues

Download lambda values ​​of various building materials

Boundary structure of a building U value of the building materials from thermal conductivity and thickness of the structure can be calculated.

Should an energy certificate?

• I do not know what that is?
• not be just a waste of money
• it would be important to know all energy users
• I do not know enough, would I need more information
• would be interested in the specific calculations
• As a professional would need help

The above (several articles) continuously since the beginning of 2008 you can vote

An upgrade of building energy as a first step in building energy condition must be assessed. This is an audit to properly define. The energy audit certification of similar aim, to explore the energy characteristics, to determine the problem and propose solutions for improvement. This task is also building energy professionals, energy auditors conducted throat. So once again we have reached in the previous article discussed topic of certification, auditing, or need to.

In Hungary, the buildings in the 7/2006 TNM system according to a threefold requirement must be met.

• I The boundary elements of the heat transfer structures and fenestration requirements.
• II. The specific requirements for heat loss factor value.
• III. The total energy requirement characteristics.

Above 2006. September 1 started after the building permit process will apply after that date is for a building permit in the buildings above requirements must be met. The above date is a milestone in our building energy point of view.

At some time after practice and should have developed the principle that the energy point of view of the best new buildings, so these values ​​should be the highest. If the real estate market, this principle applies, then everyone's interests to its own building a new building to improve energy levels, this raises the value of the building and its energy cost reductions achieved.

That this is a building owner can do, especially in size to house the energy point of view, what are the characteristics of a physical home energy and how it transformed or renewed the house to meet these requirements.

In the next section of this triple system requirements, the details and we can read ...

You can also volunteer végeztetne energy test?

• interested in the flat faults, detailed investigation was finished
• interested in the flat faults, would have a very simple test
• hibahelyekket know, this test can not be
• only if required to do so
• Only if I knew the substance was being accomplished
• waste of money

The above write the recently launched Energy Awareness episode part where we try to emerging technical issues to walk around and proposals megfogalmazni.Ha a problem or question is, what considers not only you but many people were affected, send it to us and if we decide, you can to reflect upon it in a separate article
