Multi-Objective Optimization Model for The Selection of Measures for Energy Efficient Retrofitting of Building Envelopes

Abstract

Within this paper, a multi-criteria decision-making model for evaluating the energy efficiency of building construction measures for new or existing buildings will be presented. The proposed model observes the optimization process simultaneously through the four most important aspects of energy efficiency: economic aspect, energy consumption, environmental impact and indoor comfort, taking into account factors that may occur in the building environment during its operation, such as inflation and currency depreciation/appreciation. The model introduces dynamic thermal parameters of the wall that reflect a thermal accumulation of the building envelope and its ability to provide thermal comfort in time-varying atmospheric conditions in the building environment.
