So what should we do to our houses now built a new building to bring the level of energy?

First, determine what you building? Assign expert (expert in sustainable design, energy auditortól) an audit.

This idea was important to emphasize, because the current practice is that the homeowner decides to hőszigetelteti the house. This makes it even so, because many of the heating bill, and you want to reduce or friends told him how much it reduced the gas bill, so he can have done it. But the situation is not that simple. Look why do not you?

Generally accepted rule of thumb is that one-third of a building's heat loss through walls, one-third of the roof, windows, doors, and one-third of the produce. However, this varies per building, and it is very well return.

For example, a building with the roof surface, disproportionately greater than the surface of walls, the roof insulation to improve the most important task. Or when an old building with thick walls are (and therefore relatively better thermal insulation is provided), but the building is very ill-fitting and non-insulating glazed old windows, and therefore a disproportionate number are in the building will, mutatis mutandis, the windows should be addressed and thus improve the energy state. The number of houses built earlier architecture, thermal bridges which lead to the existence of an energetic appeal to be recognized before the renovation and refurbishment of the solution must be found out. This, however, a professional can properly assess. So, after a survey of owners of well-qualified to be able to decide. Before hundreds of thousands or millions to spend, so it sure pays off when service professional.

A dedicated audit is good to include:

- The purpose of building and related basic data and requirements definition.

- The geometric definition of the data.

- The surface / volume ratio calculation.

- The specific heat loss factor is allowed to specify the value.

- The specific heat loss factor is designed to determine the value. Control the risk of overheating in the summer.

- The net heating energy demand calculation.

- The heating system loss determination.

- The heating system is the definition of primary energy demand.

- The hot water supply net heat demand calculation of the losses of melegvizellátás definition of electric utility and energy needs to be determined.

- The hot water supply of primary energy needs to be determined.

- The ventilation system of heat balance calculation, the calculation of the losses of the system, the system power requirements definition, system definition of primary energy needs.

- Primary energy demand for cooling calculations.

- The annual lighting energy requirements of the definition.

- Building their own systems from the current definition of income.

- The building's overall energy performance calculations.

Above we can see how conditions play a role in making our house how the energy state. Be sure to use so if they were finished, and then decide according to that investment, most important, and what the amount of results, and what is the payback period? In many cases, the exchange of windows you choose, because it is very fashionable today, but maybe they are not the biggest sources of heat loss and can not be recovered so quickly as the most urgent tasks include! Maybe this is the house on our results is larger reconstruction, modernization options.

The work order of important terms you'll find the following:

The thermal upgrading of the heating time before the upgrade do, because a comprehensive renovation, the building needs greatly reduce heat. So maybe a new heating boilers and radiators are much less powerful enough, which positively influences the efficiency of new heating.

In works such as external wall insulation subsequently, the cellar ceiling, floor or the top level of the heat insulation of the other renovations are separate from and may be carried out.

The renovation of windows, external or internal insulation before or at the same time must be performed, because the new windows must be connected to the insulation plane.

The outer insulation of the facade, however necessary renovation carried out by the most economical.

The roof flat roof insulation or other insulation work independent from, but it is economical only on the roof other necessary renovation works (such as roofing replacement) should be implemented together.

So if you are considering upgrading our overall energy, we discuss an energy consultant. This work also details several years elhúzva may be accomplished, however, the order of the experts can give good advice.

Drop a few more words penészesedéséről buildings.

A common problem in older buildings, the building's walls and floors of moldy. The mold may be the windows repaired subsequent leaks occur. The leak is repaired because the ventilation is fundamentally changed. The filtration reduced the loss by reducing the strength of natural ventilation, you absolutely must make up for frequent ventilation.

In the absence of old buildings, often because of poor insulation, the heat transmission coefficient of the walls so high, so the introduction of the cold wall so that the inner surface temperature is low. If this is the surface temperature is lower than the relative humidity of the dew point temperature, the vapor condenses. For example, 20-degree air temperature and relative humidity of 60% of the dew point temperature is about 12 degrees.

If a wall inside surface such as a wreath of cars, corners where the thermal bridges due to the dew point falls below the temperature (for example, the koszorúnál 12 degrees falls below the wall inner surface temperature), the reduced air flow due to the appropriate organic medium for the existence of (eg wallpaper or painting as well) starts to mold growth. Old buildings often have reinforced the shrouds, and lintel is fully insulated ones life.

The good légzárású windows because of the increased relative humidity in the air of the room and making it even more surface temperatures (ie, better insulating relatively well) can lead to condensation.

Thus, the subsequent isolation of windows necessarily have to pay attention to the frequent and regular ventilation, the ventilation habits change drastically.

The best solution of course is a modern building ventilation system.

However, poorly insulated buildings with heating power is needed, making the room more air flow (convection) is created which prevents condensation. The building is well insulated so that heat output is much smaller than the lower convection which may increase the risk of mold growth because of less convection does not adopt completely
