摘要：The aim of this article is to present a methodology and an approach for energy efficiency optimization for buildings, connected in microgrids. The initial investment costs for the building and the energy costs are optimized while the environmental pollution is minimized at the same time. A bi-criterion optimization problem is formulated. It is solved by a multi-objective genetic algorithm in MATLAB. The possibilities of the approach are illustrated by the optimization of the energy efficiency of a group of three-storey houses connected in a microgrid. The obtained results demonstrate that the proposed approach could be implemented for different real problems concerning the buildings energy efficiency and may be helpful for construction managers, architects and decision makers in this area.
