TI  - Comparison of heat gain values obtained for building structures with real and constant properties
AB  - The magnitude of energy consumption due to the heating and cooling of buildings has led to the demand forincreasing the thermal performance of building structures. Many investigations are presented in literature arguingto find the effect of each thermophysical property on the thermal characteristics of building components, while theproperties have been assumed as independent of each other. In this context, this paper focuses on the effect of eachproperty on heat gain value utilizing relationships between the measurement values of the thermophysicalproperties of building structures. In the previous study, 102 new wall samples were produced, their thermophysicalproperties were tested and expressions among these properties are obtained. In this study, the heat gain valuesthrough the structures are computed using the solution of the transient heat transfer problem by using both theobtained expressions between the thermophysical properties and assumptions proposed from the literature. Resultsobtained for varying and constant thermophysical properties have been compared with those values presented inthe literature. The results show that the assumptions are not realistic in a significant number of cases. Moreover,if one of the thermophysical properties of a material is known, heat gain values can be calculated easily for theselected wall or roof types.
