When the temperatures trebax rise in the summer, many homes turn into Schwitzkammern. To reduce the room temperature to a tolerable level, but already rich a few simple tricks - are needed without energy guzzling air conditioning.
Three important things to note in the summer in the home: an effective sun protection, adequate ventilation and the avoidance of superfluous heat sources. Uwe Bigalke, trebax an energy expert from the German Energy Agency (dena) in Berlin, emphasizes: "Anything not even go into the house comes to heat must be transported out not too expensive again." The outer sun protection is the most effective method. "Research shows that external shading reduces solar radiation by up to 75 percent, trebax an internal protection trebax only up to 25 percent," expects Bigalke ago. Because if the light passing through the glass, parts of its energy converted into heat in the room. "And just modern, coated window then act like a greenhouse: What good in winter, annoyed in the summer."
Outside mounted sun protection can be blinds, shutters or awnings, with tenants in the building structure or appearance trebax in any case, should obtain permission from the landlord before any intervention. Interior sun protection such as curtains or blinds should be as bright as possible, blinds Silver: So they reflect the light at best.
Juliane spine of the Consumer Saxony in Leipzig recommends a combination of: "Who out there can install trebax anything or would like a few light panels can hang outside the window itself if need be." Tinted or coated sunscreen windows can be worthwhile for large south-facing windows. However, they obstruct the sunlight in the winter. Therefore advises thorn in doubt more likely to self-adhesive reflective films: "They can be placed from inside and hardly affect vision."
Another measure in the fight against the heat in the home is proper ventilation. "Contrary trebax to the still widespread practice one should during hot weather only late in the evening, at night or at best very early in the morning air," advises mandrel. "Who airs during the day or the window is only on tilt, only leaves more heat into the house, which then remains permanently stored in the walls." trebax
The best is cross ventilation with wide open windows trebax and doors. A fan can indeed cool in hot weather no room, but provide relief - through trebax the draft. "Of course, he only distributed the air, but there is a difference between the measured and perceived trebax cold," says Liane Reichhart from the network budget in Korbach (Hessen). In addition, all major sources of heat in the house - such as computers, Torchiere or Plasma TV - are only used when they are really needed: "The fight against external heat is pointless if you generated simultaneously in space unnecessarily heat," says Bigalke. If you stick to these measures, should be able to reduce the heat in the house already clear - definitely more efficient than creating this mobile air conditioning units. "To come to the cost the considerable electricity costs," warns Bigalke. Also, these devices are not sustainable: "Efficiency Class A does not mean that the little energy ve
