Influence of using clay block with increassed mass on energy performance of an office builidng in Nis

The objective of the research was to compare various types clay blocks in terms construction thermal inertia parameters and influence they would have on energy performance office building located Nis. For this, a new type block with increased mass is proposed, custom approach for determining all relevant indicators described, intensively relying simulations. Fourteen configurations external walls made block, including newly proposed mass, were investigated using EnergyPlus weather file obtain storage indicators, i.e., time lag decrement factor. In addition, same model used check this has served by low temperature radiant system. Results show possibility reducing heating consumption 3.65% under similar wall U-values.
