Сomputer modeling and optimization of energy efficiency potentials in civil engineering

Abstract

The paper presents the results of creating a software package for optimizing the calculation of potentials of alternative energy sources in the regions of Ukraine based on BIM technologies (AutoCAD, ArchiCAD, Revit), which are combined using the IFC format. The software package uses mathematical and graph-analytical models of climate and energy zoning in the regions of Ukraine, and with the help of MS Excel visualizes the research process and automates, accelerates optimal decision in design, reconstruction and construction. The process of forming a database for traditional energy sources (electricity, oil products, natural gas, coal, firewood) and a database of energy potentials of alternative energy sources (solar energy, wind energy, geothermal energy, hydropower of small rivers, potentials of livestock and crop biomass potential of excess pressure of natural gas, potentials of heat of soil, ground and sewage, potentials of energy of peat and forest waste) for all regions of Ukraine. The structure of the software package and a block diagram has been developed, all indicators are reduced to a single unit of measurement (MW*h / year per 1000 people). To analyze and make optimal decisions, informative-illustrative bar and sector pie charts are built in MS Excel on five main areas of energy consumption, taking into account alternative energy sources for each region of Ukraine. The general analysis of energy consumption and optimization calculations are carried out with the help of informative-illustrative diagram SANKEY, which is created with the help of "SankeyDiagramGenerator", and visualizes the whole process of graph-analytical modeling of energy consumption in Ukraine.
