Tracks and isochrones have been computed in the range of initial masses 0.15- 20 Mo for a grid of 39 chemical compositions with the metal content Z between0.0001 and 0.070, and helium content Y between 0.23 and 0.46. The Padovastellar evolution code has been implemented with updated physics. New syntheticTP-AGB models allow the extension of stellar models and isochrones until theend of the thermal pulses along the AGB. Software tools for the bidimensionalinterpolation (in Y and Z) of the tracks have been tuned. This first paperpresents tracks for low mass stars (from 0.15 to 2.5 Mo) with scaled-solarabundances and the corresponding isochrones from very old ages down to about 1Gyr. Tracks and isochrones are made available in tabular form for the adoptedgrid of chemical compositions in the plane Z-Y. An interactive web interfacewill allow users to obtain isochrones of whatever chemical composition and alsosimulated stellar populations with different Y(Z) helium-to-metal enrichmentlaws.

Scaled solar tracks and isochrones in a large region of the Z-Y plane I. From the ZAMS to the TP-AGB end for 0.15 - 2.5 Mo stars
