Comparison of Thermal Performance of Newly Produced Lightweight Wall and Roof Elements for Energy-efficient Buildings

Öz:
In this study, both experimental and theoretical investigations are performed to obtain newconcrete types with high thermal insulating characteristics for energy-efficient buildings.In this regard, 102 new concrete wall samples were produced using different aggregates atdifferent volume fractions, and their thermophysical properties were tested according to ENand ASTM standards. The experimental research focused on developing new wall or rooftypes with higher thermal insulation properties in order to reduce the energy consumptionof buildings due to heating or cooling. In order to specify the thermal performance of developed lightweight concretes, an analytical solution method is developed by the ComplexFinite Fourier Transform (CFFT) method to estimate heat gain utilizing measured thermophysical properties data of those samples. The results indicated that the reduction in heatgain value was obtained as 83.21 % for the PC100 wall corresponding to conventional concrete. Consequently, the thermal insulation effect of those samples shows excellent potentialfor development.
