DETERMINATION OF OPTIMAL PACKAGES OF ENERGY EFFICIENT MEASURES FOR PUBLIC BUILDINGS

Abstract

The paper is devoted to the problem of improving the energy efficiency of public buildings maintained with funds from the state and/or local budgets. Optimization modeling is proposed as an instument to determine the optimal packages of energy efficiency measures according to the criterion of maximum achieved savings of fuel and energy resources. Approbation of the mathematical model on actual data has shown its practical value - depending on a given budget, the optimal packages of energy efficiency measures for public buildings (on the example of Zaporizhzhia city) are determined. Based on the results of computational experiments, energy efficiency measures with the best and worst ratios of implementation costs and achieved savings of fuel and energy resources were identified. The impact of additional constraints on the composition of an optimal package of energy efficiency measures was shown to make informed and rational decisions on investing in energy efficiency improvement projects for public buildings.
