Hinweise zu den Daten: Heizgradtage sind ein Mass für den Einfluss des Wetters auf den Heizenergieverbrauch eines Gebäudes. Heizgradtage sind die Differenz zwischen der gewünschten Raumtemperatur (20 °C) und der mittleren Aussentemperatur eines Tages, falls diese Aussentemperatur unter einer bestimmten Heizgrenze liegt. Für die Berechnung wird die Heizgrenze 12 °C verwendet.
