Dear,

can anyone explain me the logic behin the formula in attachement? It is the
formula to calculate u in case the off-heating is larger than the value of
4+0.25T

Is there some background information provided for the explanation of the
parameters and formulas for the calculation of the utilisation factor for
heating and the value Tsc (page 143-144 in the SAP2009 document)?


Thanks,

Leen
