Namely, starting from the generic Gepner models for Calabi-Yau 3-folds, we construct the non-SUSY heterotic string vacua with the vanishing cosmological constant at the one loop. We especially focus on the asymmetric orbifolding based on some discrete subgroup of the chiral $U(1)$-action which acts on both of the Gepner model and the $SO(32)$ or $E_8\\times E_8$-sector. We present a classification of the relevant orbifold models leading to the string vacua with the properties mentioned above.
