Compartment-contributions about the heat-protection, to the insulation and moist walls

Not only the insulation belongs to a balanced heat-balance sheet at a building as it intends the calculation after the EnEV. (Criticism about the EnEV of Prof. Meier.)Soon, each German construction with a thick isolation is enveloped. The intensified EnEV will already make it possible. With the Unit of heat-transfer, other influential factors, like heat-storage-ability, remain the humidity, phase-alterations in the wall-cross section, the heat-convection or the virtually unknown attempt to influence through the Hheat-radiation unconsidered. Already the Heat-stream is not correctly determinable. The physical connections are very complex. If the coupled dampness and heat-transportations are shaped by the construction unfavorably, so the moist-formation can occur long-term. Is here to be attributed a special role to exactly the unobstructed diffusion.
A meaningful inclusion of the heat-storage helps save costs for heating. A simplified measurement of the saved solar-energy shows this in the stonework.

Heat-bridge at heat-isolation heat-bridges is prefabricated parts, for example at a property, where a lower surface-temperature is available in the comparison to other beside-lying prefabricated parts and prefabricated part-sections respectively. The consequences are a higher moisture-burden, that leads to the known mold-appearances and to the elevated material-wear. Summary of the contributions to heat-bridge. They are to the evaluation chemical and physical qualities of construction-materials important.

Roof-projectile-extension - problem-areas heat-bridges and joints. Exactly at the self-extension, essential criterions, that become starting point for a serious construction-damage, that one recognizes first, are overlooked here if it is too late.

Redevelopment, heat-isolation and heat-bridges, 1994 (19 KB)
Often, the question is asked, first the heater rearranges or the thermal behavior of the property improves. Besides the heat-isolation, also more factors play a role. The building should be shined on as much as possible by the sun above all in the winter and opens..., at an example-object, no energy-saving came after the installing a Heat-system-system,...

Mold on heat-bridges - general representation and showing of constructive lacks at the roof-projectile-extension, 1994. The energy-cycle in a property is determined by many factors that only a part of these connections is known. At the moment, one gets the bearings mainly only on the u-Wert.

With thermal unfavorable houses already is meaningfully an insulation. In the contribution Evaluation of the consumption of heat at an increase-family-house 1958 (Block-construction-manner, an assessment takes place.

Statistical evaluation of the additional insulation. We would be very happy if you take part in this statistical rise (of course anonymous) to the energy-consumption of the buildings. A few crosses and ready.

Inside isolation at the attic-extensionAn inner-isolation, can lead to a construction-damage through heat-bridges and joints for example at the roof-projectile. A proper implementation is necessary. (Pictures of implementation-mistake and to construction-damage.)

Feuchtes MauerwerkMoisture in the stonework at old buildings is a problem the redevelopment of moist walls since the hygroskopische quality of the salts is underestimated. Here, the wall-salts, her/its/their redevelopment and the different procedures about the drainage with her/its/their function-manner and price-confrontation are introduced extensively.

Right ventilation is Zur conservation of the health a certain ventilation-installment necessary. This is in the contradiction to the the intensified requests of the EnEV 2000. Not only the humidity but also pollutants and radioactivity is exchanged with the right ventilation.
