Energetische Sanierung betrifft Altbau bzw. Bestand und umfasst die Verbesserung einzelner Bauteile. Dazu z\u00e4hlen bspw. D\u00e4cher, W\u00e4nde, Fenster, Keller bzw. Sockel. Auch die komplette Modernisierung zum KfW-Effizienzhaus f\u00e4llt unter eine energetische Sanierung. Ziele sind, den Energieverbrauch zu senken, die D\u00e4mmung zu verbessern, geringere Heizkosten zu erzielen und den Wohnkomfort zu erh\u00f6hen.\u00a0<\/p>\n

Bei einer energetischen Dachsanierung m\u00fcssen Sie mit etwa 450 \u20ac pro m\u00b2 Dachfl\u00e4che rechnen, da hierf\u00fcr ein Ger\u00fcst, Materialien sowie Dachdecker- und Klempnerarbeiten erforderlich sind.
