EXERGETIC ANALYSIS OF A BUILDING AS A KEY ELEMENT OF A HEAT SUPPLY SYSTEM

the study of complex influence weather and climatic factors their variability on needs en-ergy exergy when creating thermal comfort in a house with various engineering architectural charac-teristics is carried out. It confirmed that even for houses relatively low characteristics built accordance regulatory documents, role solar radiation formation heat balance, espe-cially at beginning end heating season, important. Studies showed due to combined external meteorological factors, improvement houses, correlation between energy demand favorable microclimate outdoor air tem-perature significantly worsens. determined this case, value approximation reliability decreases from 1 (with linear dependence) 0.55 lower maximum possible improved ther-mal today).
