A Ginzburg-Landau-like functional is proposed reproducing the main low-energy features of various possible high- superconducting mechanisms involving energy savings due to interlayer interactions. The functional may be used to relate these savings to experimental quantities. Two examples are given, involving the mean-field specific-heat jump at and the superconducting fluctuations above . Comparison with existing data suggests, e.g., that the increase of due to the so-called interlayer tunneling (ILT) mechanism of interlayer kinetic-energy savings is negligible in optimally doped 8+x.
