Energy-saving has become one of the basic strategies for developing countries like Turkey that need
energy imports. One of these strategies is energy-efficient building designs. The energy-efficient building envelope, which is one of the most important components of energy-efficient building designs, is of great importance in
terms of insulation, indoor comfort, and environmental effects. In addition, the climatic and seismic characteristics
of the regions where the buildings will be built are a matter of curiosity for building designers. It is an important problem to determine the effect of climate and earthquake zones on the building envelope. In this study, the
effects of climate and earthquake zones on the costs in the building life cycle, together with the building envelope
properties, are investigated. Life cycle cost assessment (LCA) analysis is applied by considering the parameters of
building envelope material cost, heating energy consumption cost, cooling energy consumption cost, CO2 emission cost, embodied carbon cost, and earthquake-based repair cost. Fourteen different decision variables are taken
into account, including exterior plaster, wall, and roof insulation material, wall, interior plaster, the thickness of
these materials, window type, and window/wall ratio. Significance levels of decision variables for heating energy
consumption, cooling energy consumption and CO2 emission are calculated. It is determined that five decision variables for heating energy consumption, four for cooling energy consumption, and seven for CO2 emission are more
important. It is an interesting pattern that earthquake zones have 28%, 46%, and 13% importance for heating energy
consumption, cooling energy consumption, and CO2 emission. It has been observed that the EnergyPlus-based ANN
approach proposed for LCA analysis provides over 95% accuracy on the sample data set.
