USE OF BUILDINGS ENERGY MODELING IN DEVELOPMENT OF ENERGY EFFICIENCY PROJECTS

Abstract

Research  of  the  problems  in  different  types  of  energy efficiency  projects  in  public, residential and manufacturing facilities buildings that are or can be made by students of energy specialties with using dynamic energy modeling software for buildings and renewable energy sources. In the process of researching the mentioned problems are considered examples of works using:  mathematical  modeling  of  heat  transfer  processes,  energy  balances  and  modeling  software.  The
current Ukrainian legal base, which describes and regulates approaches for energy efficiency assessment of buildings, is analyzed also. Results. In the courseof the research typical projects for improving of the energy efficiency level of
public,  residential  and  manufacturing  facilities  buildings  are  considered,  conducted  by  the  students  of energy specialties with using software packages such as RETScreen, EnergyPlus, DesignBuilder, etc., the technical potential of the mentioned software packages are analyzed, the methods of processing of input data for some programs are considered, the main characteristics, advantages, disadvantages and difficulties that
students face in making of energy modeling and analysis of results are presented. Scientific novelty. The existing experience of the energy modeling of buildings by students and the
analysis  of  certain difficulties  that  arise  in  modeling  is  systematized,  which allows  to  optimize the  whole process of research of energy efficiency of buildings. The  practical  significance.  As  a  result  of  the  stated  research  the  potential  of  using  different software complexes for student training in energy modeling of buildings and analysis of the criteria of the energy efficiency of buildings in Ukraine was determined.
