In den 70er-Jahren des letzten Jahrhunderts waren sie Mode: Luftbilder der eigenen Liegenschaft. Wie liess sich der Stolz auf das eigene Haus besser illustrieren als mit einer grossformatigen Luftaufnahme? Nun – die Zeiten haben sich ge\u00e4ndert: Vertikalaufnahmen geh\u00f6ren im Internet zum Standardangebot von Kartenprogrammen.<\/p>\n

Eine \u00e4hnliche Mode zeigt sich aktuell: W\u00e4rmebilder (oder Thermographieaufnahmen) sind in. Farbige Aufnahmen, die die Oberfl\u00e4chentemperaturen der abgebildeten Fassaden zeigen, als Indikator f\u00fcr den W\u00e4rmehaushalt auf dieser Fassade.<\/p>\n

Wer gerne ein Falschfarbenbild seines Hauses irgendwo verf\u00fcgbar haben m\u00f6chte, soll sich solche Bilder herstellen lassen. Aber: die Bilder haben geringe Bedeutung f\u00fcr Energiepolitik und Energietechnik!<\/p>\n
