This paper focuses on the topics U-values and indoor air temperatures of unheated basements with uninsulated cellar ceilings. Measurement values are compared with calculation procedures suggested by building regulations. Concerning the U-values
it is shown that they are typically considered to be higher (i.e. worse) in uninsulated existing constructions than they effectively are.
Measured temperatures in seven basements are higher (around 8 K) than a calculation according to regulations would yield. The
paper derives suggestions for the adjustment of calculations focused on existing residential buildings.
