  The equilibrium transport properties of an elementary nanostructured device
with side-coupled geometry are computed and related to universal functions. The
computation relies on a real-space formulation of the numerical
renormalization-group (NRG) procedure. The real-space construction, dubbed
eNRG, is more straightforward than the NRG discretization and allows more
faithful description of the coupling between quantum dots and conduction
states. The procedure is applied to an Anderson-model description of a quantum
wire side-coupled to a single quantum dot. A gate potential controls the dot
occupation. In the Kondo regime, the electrical conductance through this device
is known to map linearly onto a universal function of the temperature scaled by
the Kondo temperature. Here, the energy moments from which the Seebeck
coefficient and the thermal conductance can be computed are shown to map
linearly onto universal functions also. The moments and transport properties
computed by the eNRG procedure are shown to agree very well with these
analytical developments. Algorithms facilitating comparison with experimental
results are discussed. As an illustration, one of the algorithms is applied to
thermal dependence of the thermopower measured by K\"{o}hler [PhD Thesis, TUD,
Dresden, 2007] in Lu$_{0.9}$Yb$_{0.1}$Rh$_{2}$Si$_{2}$.
