Energiepolitik<\/span><\/h2>

Die Welt ver\u00e4ndert sich durch CO2 enorm\u00a0<\/sub>emissionen; es kann nicht auf nat\u00fcrliche Weise mithalten. Deshalb ist Energiesparen heute wichtiger denn je. Die Bauwirtschaft kann zu dieser Einsparung beitragen, indem sie die Geb\u00e4ude thermisch d\u00e4mmt. Das Heizen und K\u00fchlen von Geb\u00e4uden hat einen Anteil von 48 % am europ\u00e4ischen Endenergieverbrauch. W\u00e4rme\u00fcbertragung kann an jeder Oberfl\u00e4che des Geb\u00e4udes stattfinden, aber Fenster und andere \u00d6ffnungen verursachen den gr\u00f6\u00dften Energieverlust. Neben den T\u00fcren und Fenstern k\u00f6nnen sich Bauherren auch auf die Isolierung der W\u00e4nde, D\u00e4cher und B\u00f6den konzentrieren, um den Gesamtverlust zu reduzieren.<\/p>

Aus europ\u00e4ischer Sicht besteht das Ziel darin, die Emissionen bis 2030 um 60 % zu reduzieren. Nach Angaben der EEA (Europ\u00e4ische Energieagentur) stehen langfristig nur begrenzte Fl\u00e4chen f\u00fcr Wind- und Solarenergieanlagen zur Verf\u00fcgung. Emissionen k\u00f6nnen nicht allein durch den Ersatz der Energiequelle durch gr\u00fcne Energie reduziert werden. Dies bedeutet, dass fossile Brennstoffe noch lange bestehen bleiben und m\u00f6glicherweise zus\u00e4tzliche Vorschriften mit sich bringen. Deshalb ist es wichtig, auch in den Geb\u00e4uden Energie zu sparen.<\/p>

Bei der Berechnung der Energieeffizienz des Geb\u00e4udes gibt es zwei Hauptziele. Einer davon ist die W\u00e4rme\u00fcbertragung an den Oberfl\u00e4chen. Der zweite Punkt ist die Luftdichtheit. Diese beiden Parameter k\u00f6nnen mit internationalen Standards wie EN ISO 6946, EN 13829:2001, ISO 9972:2006, AISI S250, ASTM E779-10, ATTMA TS1, ICC IECC-2018 usw. berechnet oder getestet werden.<\/p>

Beispieldetail<\/span><\/h2>

Kaltgeformte Stahlbaugruppen weisen Hohlr\u00e4ume zwischen den Profilen auf, die mit Isoliermaterialien gef\u00fcllt werden k\u00f6nnen. Zus\u00e4tzliche Abdeckmaterialien oder -schichten k\u00f6nnen W\u00e4rmebr\u00fccken verhindern. Innen-Au\u00dfenverkleidungen und F\u00fcllmaterial im Hohlraum k\u00f6nnen als Standarddetail im Leichtbau verwendet werden. Um die erforderliche W\u00e4rmed\u00e4mmung aufrechtzuerhalten, k\u00f6nnen die Details in Abbildung 1 verwendet werden. Die Auswertung des R-Wertes, der den thermischen Widerstand beschreibt, kann anhand der Codes erfolgen.<\/p>

Energy Policies The world is changing immensely due to CO2\u00a0emissions; it can not keep pace naturally. Therefore, saving energy is more important than ever today. The construction business may contribute to this saving by insulating the buildings thermally. The heating and cooling of buildings have a ratio of %48 at Europe\u2019s final energy consumption.
