Abstract: Calculating energy savings and emission–reduction potentials for municipal energy systems requires computer models with high spatial and temporal disaggregation. Consequently, the computational effort necessary to run such models is considerable. For the optimization models ecco, ecco-solar and deeco, this problem has so far been solved by assuming that the time intervals considered are independent of each other and may, therefore, be optimized consecutively. For minimization of primary energy inputs and emission of pollutants, this approach is sufficient. Optimization of monetary costs and placing of intertemporal emission limits, however, is not possible. Based on fuzzy-set theory, we develop a method with which the up to 8760 input-data sets of the model can be compressed by 1–2 orders of magnitude such that the remaining ones may then be optimized simultaneously. Test runs with original and compressed data sets show good agreement, thus proving the functioning of the method.
