Özet
The growing concern about energy consumption of heating and cooling of buildings has led
to a demand for improved thermal performances of building structures. Many investigations are
present in literature arguing to establish the influence of each thermophysical property on the thermal
characteristics of building components, while the properties have been assumed as independent of
each other. In this context, this paper focuses on the effect of each property on heat gain value
utilizing relationships between the measurement values of thermophysical properties of building
structures. In the previous study, 102 new concrete wall samples were produced, their thermophysical
properties were tested, and expressions among these properties are obtained. In this study, the heat
gain values through the structures are computed using the solution of transient heat transfer problem
by using both the obtained expressions between the thermophysical properties and assumptions
proposed from the literature. Then, the results obtained from the study and the literature have been
compared and discussed in this study. The results show that the assumptions are not realistic in a
significant number of cases. Moreover, it has been proved that if one of the thermophysical properties
of a building material is known, the heat gain values can be calculated easily for the selected wall
types
