EFFECT OF VARIATION OF OPERATIONAL REGIMES IN BUILDING ENVIRONMENT ON RESULTS OF ITS ENERGY AND EXERGY ASSESSMENTS
Journal Title: Civil and Environmental Engineering Reports - Year 2017, Vol 1, Issue 24
Abstract
For further development of the dynamic exergy analysis within built environment the work proposes to take into account stochastic nature of variations of operational regimes. Using the probability theory and statistics methods, the set of parameters considered as relevant for uncertainty conditions are presented. It is shown that characteristics of buildings (insulation, window performance, heat recovery, etc.) and type of the heating system have undoubtedly a strong influence not only on the energy/exergy demand and consumption but also on the sensitivity of the energy/exergy parameters to variations of external conditions. According to the results obtained after implementations of energy efficient solutions coefficient of variation of energy/exergybased parameters can be increased up to two times.
